Bop and Market Design Economics

{Acknowledgment}Professor Dr. Peter Knorringa arises the question of how economists can contribute to the emerging field of Bottom of Pyramid. This question motivates me to write this paper.

{Abstract}Theory of bottom of pyramid without doubt is one of the most influential theories in business literature the past decades. More than 4 billion people live in poverty. Prahalad suggests; “large-scale and wide-spread entrepreneurship is at the heart of the solution to poverty eradication”. This paper suggests that economic theory can contribute to BOP literature.  This paper utilizes two influential economic theories; transaction costs and market design economics, to further enrich BOP literature.

\section{Introduction}Prahald introduces new tool for poverty reduction. In his book “Fortune at the Bottom of Pyramid” he notes that; BOP (the 4 poor billion people) can and must involve in market as a customer and as a part of production process . The poor not only should not be excluded from market but they should be included in the market as a profitable customer class and active participants of value chain. He provides examples of companies that successfully enter to the BOP market; such as Casa Bahia, CEMEX, The Annapurna Salt Company, HLL Shakti, Jaipur Foot, ICIC Bank, ITC e-Choupel. These companies approach the poor as consumers and create win-win situation. That is, by selling to the poor companies gain profit and the poor get access to the products that contribute to their wellbeing. An example is Annapurna Salt Company that by selling idolized salt to the poor decreases IDD among the poor in India. \\Technological advancements decrease production costs and make products affordable for middle and low economic classes. An example is reduction in the cost of agricultural products in the past decades due to the technological achievements. Nonetheless, the Prahalad raises the question of how companies can reduce cost of products by changing the management system. That is, decreasing the cost with the assumption of stagnant technology. \\Prahalad , and BOP literatures, briefly answer to the aforementioned question. Nevertheless, economic theories discuss extensively the ways that firms can reduce products’ costs, given technology stay constant. Hence, economic theory provides robust theoretical framework for explaining how firms can extend their market to BOP \cite{1}. \\Institutionalists economists introduce two types of costs that determine the final price of products: primo, transformation cost which is cost of transforming raw materials to the final products. Secundo, transaction costs; as north define it; “all those costs incurred in operating an economic system”. An example of transaction costs is lack of trust in a market to the poor. The result is that the interest rate for the poor is by far more than normal interest rate. \\Technology reduces transformation costs, however, economic theories has focused on decreasing transaction costs. The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel has been awarded to the topic of transaction economics. The reason for that is the important implications of transaction cost economics in several fields.\\Market design economics is an emerging field in economics that creates a rigorous mechanism for tackling with transaction costs. This field utilize gamethory, mathematics, and IT to find solutions for market failures and transaction costs. Market design economics resuscitates several markets that severely suffered from transaction costs; kidney exchange market, high school admission, working position for new doctors and so on.\\This papers link economics theories; explicitly transaction costs economics and market design economics, with BOP literature. This connection can further enrich both fields and contribute to life of the poor. \section{Bottom of Pyramid at the Glance}Since the early 1950s developed countries have provided financial aids to developing nations. The common believe has been that capital is the main obstacle for development and providing financial capital is the main path for poverty reduction and development (Foreign Aid: Its Defense and Reform, page 24). The idea of financial aid as the path for poverty reduction become a dominant idea among majority of the agencies who aimed at helping the poor people; such as international organizations, NGOs and so on. \\Graph1\\ \includegraphics[scale=0.4]{11}\\Financial aid has increased from \$41 billion in 1970 to \$107 billion in 2005. That means an average of 3.1\% growth per year. Furthermore, in Monterrey consensus\footnote{http://www.un.org/esa/ffd/monterrey/MonterreyConsensus.pdf }the G8 has committed to double the aid to developing countries. From Monterrey Consensus till the end of 2010 the aid has increased by 50 percentages. (Trends and issues in development aid; Homi Kharas) In spite of the substantial increase in the financial aid, our world still suffers from extreme poverty. According to World Bank, in 2011 Over 1 billion people live in the income less than \$1.25. Moreover, 2.2 billion people live on less than \$2 per day. \footnote{http://www.worldbank.org/en/topic/poverty/overview }.  The statistics reveals that the classical approach for poverty reduction has failed. The ironny is that the other approaches has to be taken. \\In 2002 Prahald propose a new instrument for poverty reduction. In his article “The Fortune at the Bottom of the Pyramid,” (January 2002), he notes; “large-scale and wide-spread entrepreneurship is at the heart of the solution to poverty” (refrence). This theory suggests that, BOP (4 billion people) can and must involve in market as a customer and as a part of production process. The poor not only should not be excluded from market but they should be included in the market as a profitable customer class and active participants of value chain.  He declares that, philanthropy and altruistic approach cannot significantly contribute to the life of the poor. The reason for that is, providing financial aid is not sustainable and it makes the poor dependents. Large scale companies should integrate the poor in their production value chain. Moreover, large-scale entrepreneurs with help of NGOs and local governments should approach the poor as consumers. A win-win relation between the inhabitant of BOP and producers is needed in order to empower the poor. \\In the BOP literature there are several examples of successful companies who enter into the BOP market; such as Casa Bahia, CEMEX, The Annapurna Salt Company, HLL Shakti, Jaipur Foot, ICIC Bank, ITC e-Choupel.\\One of the most interesting examples is Annapurna Salt and its help to eradication of Intellectual Developmental Disorders (IDD). \\IDD is the world’s leading cause of mental disorder. In India more than 200 million people are in the risk of IDD and 70 million already have mental disorder. \\Iodine prevent occurrence of IDD. Everyone including the poor use salt, hence, it is easy to prevent IDD by consumption of iodized salt. Nonetheless, it is difficult to educate the poor and incentives them to purchase iodized salt rather than simple salt. The reason for that is the poor used to low price for salt and are not willing to pay an extra margin. In addition, they are not well educated have little knowledge about treatment and prevention methods of IDD.\\Hindustan Lever is a subsidiary of Unilever that operates in India. It operates since 1930 and now it is the largest branch of Unilever, It has more than 52\% of the total wealth of Unilever. Hindustan Lever Research Centre innovates products that match to Indian demand. Hindustan Lever feels the gap of iodized salt in the Indian market. Hence, the research centre aimed at creating an iodized salt that match well to the Indian kitchen of middle and low economic class. They found that in Indian cooking iodine vanishes. Consequently, the research centre aim at a salt that can keep the iodine in the salt for longer period, be storable, as well as do not vanish in the Indian cooking. The result of the research was an iodized salt that is called Annapurna. \\The difficulty of introducing Annapurna into market was to educate the poor for paying a higher price for iodized salt. The Indian villages have barely access to TV, Radio, Internet and other social network. Hence, it is extremely difficult to reach the poor via advertisement and social media. To overcome this problem, Hindustan Unilever introduces a new selling and advertisement methods. \\The Hindustan Unilever introduces Shaktis. Shaktis are Indian ladies who are member of self-helping groups in rural area in India. Hindustan Unilever, give them a fix salary for educating the poor about benefit of iodine. Moreover, Hindustan Unilever, give them a commission for selling their products. Shaktis are well connected and explain the benefit with respect to local education level. \\The result of the new advertisement system as well as Annapurna Salt was that the Hindustan Unilever earns huge profit form this product. Furthermore, the poor health improved because of consuming iodized salt. \subsection{BOP Market}BOP Market The term “bottom of pyramid” or “base of pyramid” or simply BOP was first introduced by Prahalad in his influential paper; “The Fortune at the bottom of Pyramid”. He divides the world population to 4 economic classes with regards to their income. The last largest and poorest socio-economic class who are 4 billion and earns less than \$1,500 per year are called bottom of pyramid (refernce), graph 2. This definition is the most common definition of bottom of pyramid (Hall, Matos, Sheehan \& Silvestre 2012).  There are also other definitions of BOP, for instance Shah 2008 claim that BOP are 2.5 billion who earn less than \$2.5 per day (Shah,2008). Some other researchers define people who earn less than \$3,000 per year as BOP (Hammond, Kramer, Katz, Tran \& Walker, 2007; Subrahmanyan \& Gomez-Arias, 2008). Most of the people at the bottom of the economic pyramid are based in South Asia, Africa, Eastern Europe, the Caribbean and Latin America (Subrahmanyan \& Gomez-Arias, 2008). \\ In spite of the fact that the individual purchasing power is low in the BOP the aggregate demand is extraordinary and this make it attractive market for all companies. The GDP of nine of developing countries is about \$12.5 trillion. The main question for entrepreneurs should be how to entre and aggregate the demand. \\Graph2 \includegraphics[scale=0.5]{2BOP}\subsection{Entrepreneurship Barriers in BOP}High transaction costs act as a barrier for vibrant entrepreneurship to grow and enter into the BOP market( 5 refernces). Prahalad believes that transparency reduces transaction costs. Nevertheless, majority of BOP countries suffers from an opaque market with high transaction costs. For instance, if an Indian farmer wants to register his land he first approached by a broker. The broker will lobby with authorities and do the long bureaucratic process and ease the transaction. The cost of a registering a land for a farmer will be the registration cost plus unnecessary transaction cost; broker fee, corruption to bribe officers. As it is explained in detail in the next section, the high transaction cost leads to market failure. In this case, if the cost of bribing and broker fee be too high that farmer could not afford it and the market will fail. The high transaction not only disincentives the multinational companies to participate in the poor countries, but also it hinder local entrepreneurship grows. \\High transaction costs act as a barrier for vibrant entrepreneurship to grow and enter into the BOP market( 5 refernces).

U actually explained it with explaining the function of computer. No I did not. )C.K Prahalad  declares that there are four requirements for creating a transparent market and reducing transaction costs: Firstly, access to information and transparency in all of transactions. Secondly, fast speed in transactions. Finally, high trust level in the system (refrence). \\Mainstream development literatures suggest that implementing appropriate rules and enforcing them are the main way for transparent market (refrence). However, changing rules and institutions is not feasible, in short run, in majority of the BOP countries. BOP literature does not provide a short run and feasible solution for this problem(refrence). \\New Economists who are called market designer provide other alternative for building transparency in the short run. In the section of market design it is explained how the solution of market designer provide the four conditions that proposes by Prahald. Before, explaining different types of transaction costs as well as market design, the market at BOP will be explained. \section{Transaction Cost Economics at a Galance}In 1937 for the first time Ronald Coase notes that the neoclassical results of efficient markets obtain only in the absence of any transaction cost. He shows that, institutions play a crucial role when there is a substantial transaction costs in a market. Moreover, the results of economic activities and entrepreneurial grows depends on the transaction costs in the market.  (Ronald Coase, the nature of the firm + R. Coase, "The Problem of Social Cost," The Jouraal of Law anconomics (1980) 3:1-44 ).\\Economic activity has two source of cost, the first one is transformation (production) costs; that is, all of the costs that incurred for transforming raw material into the final product. The other type of costs is transaction costs; as north define it; “all those costs incurred in operating an economic system”. That is, the costs that a firm has to pay for bringing the final products to end consumers. Most of participants in an economy do not produce any final goods. Think of politicians, brokers, accountant, judges, and bureaucrats in general they are mainly involved in transacting sectors. Transaction costs depends on the complexity of an economic system. The more complex and opaque an economy the higher the transaction costs. In America, which is a developed country and has less complexity in comparison to developing countries, 45\% of GDP in 1970 spent on the transaction sectors. This number is by and large higher in developed countries.  \\The institutions determent economics structure of each country, and economic structure determines how the wealth is distributed. In contrast to what neoclassical economics believes, the competition among economic participants dos not always leads to efficient outcome. Economic participants design structure in such way that they gain the largest share of the wealth, even in the expense of the others. If the rules do not restrict transacting sectors they will strive for an structure in which majority of the wealth allocated to transacting sector and tiny share to production. In other words, transacting sectors can hinder economic growth. That is, inappropriate economic structure will replace the productive entrepreneurship to inefficient transaction sectors and most of a nation’s wealth spends on transaction costs. ( refernce north). \subsection{Search Cost}One of the transaction costs is search cost and there are two types of search cost; internal and external. Internal search cost is “the cognitive effort buyers must engage in to direct search inquiries, sort incoming information and integrate with stored information to form decision evaluations” (refrence). The external search costs are the costs that are beyond the consumer direct control and consumers have to decide to bear the cost or not. There are two sorts of external costs; primo, cost of acquiring the information. Secundo, opportunity cost that is spend on the search rather than working.  The example of external search cost is waiting time that is the time that a customer has to spend in order to achieve information. In addition, during the past decades the opportunity cost for the house hold has been increased, due to the increase in the women workforce and labour working hours (Weigl \& Fisher, 1976; Stigler, 1961). \\Consumers make decision on level of their search based on the cost and benefit of search. Moreover, consumer continue searching process till the marginal cost of search be equal to the marginal benefit of search (288 G.E. Smith et al. / Journal of Economic Psychology 20 (1999). Hauser et al. (1993) claims that, buyers maximize the value of search subject to a budget constraint. This implies that, a buyer maximize the search with respect to the total time that he needs to allocate for a search, which sources to search, and how much time to spend at each search source. \\Studies have shown that knowledgeable buyers incur lower search costs and therefore search more; less knowledgeable buyers incur higher search costs and search less (Srinivasan \& Ratchford, 1991; Urbany, 1986). High knowledge consumers have sophisticated decision-making structure (Rao \& Monroe, 1988). They analyze the information faster; as a result, compare the quality of different products easier (Bettman \& Park, 1980; Park \& Parker Lessig, 1981;).  In summary high knowledge consumer have two advantages in comparisons to low knowledge consumer; first of all, the cost of analyzing information is lower for them. Moreover, they are more able in linking internal and external information. Consequently, the can better mange the search level. If the external search cost, such as waiting time, is high they will be able to combine the cognition with little external search. Moreover, in the situation where the external search cost is low they use more external search. \\In comparison, low knowledge consumers suffer from higher search cost. Hence, they approach purchase decision with help of rules of thumb and heuristics (Bettman \& Park, 1980, Kahnemaen and tversky).\\There is negative relation between search cost and search level: (Stigler, 1961; Andrews, 1992; Ratchford, 1982; Newman \& Staelin, 1972). The relationship between prior category knowledge and search level is positive ( Urbany, Dickson \& Wilkie, 1989; Fiske et al., 1994).\\Consumer in BOP, the poor, faced with higher search cost in comparison to the middle and high class. The reason for that is, first of all the internal search cost is higher for the poor. That is, middle and high social class enjoy better education system and this helps them to develop their cognition and information processing skill. That result in lower internal search cost for the rich social class. Furthermore, the poor suffers from higher external cost. This can be explained by lower access to the Internet, TV, radio and other social communication among the poor in contrasts to the people and the middle or top of the pyramid. Besides that, majority of the poor live in the rural area that restrict their access to the information and make external information more costly. \subsection{Contract Costs}There are personal and impersonal transactions. In personal transaction family ties, friendship, loyalty and certainty of repeating transaction decrease opportunistic behavior. Consequently the need for detail specification in contract will decrease. Nonetheless, in impersonal transactions there is risk of opportunistic behavior in making contract. The need for detail specification in contract cost increases the contract cost. \subsection{Enforcement Cost}In case of weak judiciary system shirking and cheating will pay off. As a result, transactions are too costly and agents are less willing to participate in economic transaction. Strong judiciary system that enforce contract is essential for economic growth. In the Western world courts, legal system, and partly strong judicial system guarantee economic specialization and permit development of complex systems. Efficient markets are a consequence of institutions that provide “low-cost measurement” and enforceable contracts (refrence). \section{Institutions and Institutional Changes}North define institution as the structures that human create in dealing with each other. Furthermore, he claims that institution plus the technological change will determine the transaction and production costs. Ideally, institutions should provide transparency in and information to market participants. (reference) However, institutions can manipulate the information that they have and create an opaque market. Furthermore, Institutionalists define organization as a player that play in the game that its rules are determined by the institutions(reference).\\Institutions determine the opportunity set in the society. Consequently, economic opportunities determine the kinds of organization that come into existence. Organizations aimed at maximizing their survival possibility. They learned the skilled and knowledge that will pay off under the institutional rules(reference). North writes that:“If the highest rates of return in a society are from piracy, then organizations will invest in knowledge and skills that will make them better pirates; if the pay- offs are highest from increasing productivity, then firms and other organizations will invest in skills and knowledge that achieve that objective. ”( (reference))Two agents have power to change the institutions; economic entrepreneurs or political agents. Motivation of entrepreneurs for changing the institutions is the margin and the profit that they earn from changing the structure of the institutions. For example, an entrepreneurs have an incentive to change the institutions in a way that it reallocate the margin of middle mans to entrepreneurs. \\The direction of change is characterized by path dependence. That is a change has to be in the interests of the current players in the market. If it is too diverge from their interests they resist against changes.\section{Market Design Economics}Market design economics is about understanding of how market works, why they fail, and how to fix them (Roth What we have learned form). This field resuscitates several markets; kidney exchange market, high school admission, working position for new doctors and so on. Due to its significant contribution to different markets, the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel in 2012 was awarded to Alvin Roth, the founders of this field.  \\Alvin Roth believes that market failed due to three main reasons: 1. Thinness; that is, a market that does not attract sufficient proportion of potential market participants will fail. A successful market needs to be thick enough. \\2. Congestion: In some cases of thick markets, there is a problem of congestion. That is, the market might not be able to make transaction fast enough so that market participants can consider enough alternative possible transactions to arrive at the satisfactory one. \\3. Make it safe to participate in the market as simply as possible a. as opposed to transacting outside of the marketplace or b. as opposed to engaging in strategic behavior that reduces overall welfare. \\He shows that each of this market failure can be overcome by designing an appropriate clearinghouse. A clearinghouse is a centralized matching mechanism. In the same token, he elaborates the crucial features of modern clearinghouse in creating a transparent market: \\1) Overcome Thinness problem: it makes it possible to have a market with many participants in a virtual place. Furthermore, it reduces cost of physically participation in the market. In other words, it aggregates demand and ensure that there are enough participant in a market.\\2) Overcome Congestion in market: the processing ability of Internet makes it possible to process several transaction in a market without having congestion. Furthermore, it collects information and has faster decision process.\\ 3) Provides trusted intermediaries; it creates a safe process participant to participate and reveal their information truthfully. A middle man is trusted from both sides.\\4) Computers evolve auction markets into matching market. This means that the inefficiencies in the auction market will be replaced by certainty in the market.\\The majority of the markets that market designer have involved are matching market. That is, an agent not only has to choose but it has to be chosen. The examples of these sorts of markets are marriage market, hospital and residence that both have preferences about each other. A centralized clearinghouse has been used in order to solve market failures and transaction cost.\\The structure of this part of the paper is as following, firstly, the marriage market, which is the simplest form of matching market, is explained. Afterwards, an example of the market that failed due to unraveling is explained. In addition, it is elaborated that how a centralized clearinghouse solve unraveling in a market. The next example is about the kidney exchange market that has been failed for several years due to lack of market thickness.  Herein, it is explained that centralized clearinghouse solve market thickness problem. Thereafter, a market is indicated in which the participants are reluctant to reveal their true information. Therein, the usefulness of clearinghouse for combating this problem is elaborated. This section is followed by a case study of gastroenterologists that reflect that sometimes combination of force and implementing favorable rules are a necessity for a successful clearinghouse. Finally, the last section is about one of the most common source of market failure that is adverse selection. Therein, it is explained that the centralized signaling house can significantly change the market and overcome the market failure. \subsection{Marriage Market}Marriage MarketThe simplest form of matching problem is  “Two sided matching”, also known as “marriage market”. In the simplest form of this market there are two agents; one can propose a match and one can either accept or reject the proposal. The marriage market refers to sets of men and women that want to marry to a preferred partner. \\The assumptions of this market are; first, each woman can only marry to a man and each man can only marry to a woman. Each woman (man) has strict preferences over Men (Women). Each participant prefer to match rather than being unmatched.\\The main question in this market is how to find a match that is stable. Gale and Shapely define stable match if no “pairs” of agents have incentive to change the current match (refrence). The emphasize is on the pair, because a single participant might want to change the match, however, there is no pair that is willing to change the match. The other question, for creating an efficient matching market, is how to find a stable match that is also a dominant strategy for all pairs of players. Gale and Shapely (1962) differed acceptance algorithm always leads to stable matches and is dominant strategy for pairs. The marriage market example help to better understand the matching market and its solution. Imagine a country with three man and three women. Table 1 explain the preferences of participants:\\\includegraphics[scale=0.5]{3}\\The two stable matches are {(M1,W1), (M2,W3), (M3,W2)} and {(M1,W2), (M2,W3), (M3,W1)}. \\The mechanism that each agent achieves this result is that, in the first place a man propose marriage proposal to woman, or other way around. The proposer will propose to the most preferred choice. Receiver will select the most preferred proposer. In a case that receiver receives a proposal from his most prefer proposer, he or she will accept and there will be a match.  Otherwise, there would be no match and receivers will remain single. Each proposer who is not in match in the first round propose to the most preferred choice, which is still available, in the second round. If there is no choice available a proposer will remain single.   This process will be repeated till the point where proposer will either run out of acceptable receiver or is engaged. \\To illustrate the effects of algorithm in the aforementioned example, at the first round M1 proposes to W2, and M2 and M3 is propose to W1. The consequence of first round will be (M1,W2) and (M3,W1), and M2 proposal is rejected. Hence, the result will be the stable matching of {(M1,W2), (M2,W3), (M3,W1)}. This algorithm can be extended to a market with many participants and still leads to the stable match result. If we were to reverse the roles of women and men in the algorithm, we would actually find the other stable matching of {(M1,W1), (M2,W3), (M3,W2)}. In case that women be the proposer the stable match will be {(M1,W1), (M2,W3), (M3,W2)}. \\Suppose rather than differed acceptance algorithm, the algorithm of {(M1,W1), (M2,W2), (M3,W3)} be used. This match will be blocked by the pair (M1, W2), that is M1 and W2 have incentive to break the current match and match together. Then the match will be changed to {(M1,W2), (M2,W1), (M3,W3)}. The current match block by (M3, W2), by rematching the partner the match will be {(M1,W3), (M2,W1), (M3,W2)}. The achieved match is again block by  (M3,W1), as a result the match will change to {(M1,W3), (M2,W2), (M3,W1)}. As this match is blocked by (M1,W1) the match will be change to {(M1,W1), (M2,W2), (M3,W3)}. \\The difference between stable and unstable match can be found in aforementioned examples. In the first example there is stable match, this implies, there is no pair of match that have an incentive to break the match. Although W3 match with her least preferred match, but there is no man who is willing to break his relation and start a new relation with W3. Nonetheless, as we can see in the second algorithm there is always possibility of finding a pair that changes the match. \\In summary there is always exist stable match in matching market and the stable match(s) can only be found by deferred preferences algorithm. Moreover, a random algorithm might leads to endless cycle. In other words, in a decentralized matching market there is no guarantee that the market achieve stable match. A centralized clearinghouse is necessary condition for a market to achieve stable match. Furthermore, a decentralized match can increase the cost of transactions in market. That is, participants faced with high risk of unsuccessful match and high cost of transactions. Hence, they might show reluctant to involve in a market with decentralized matching system. In case of marriage market, a boy face with the risk of not finding his perfect match and he might not marriage at all. However, if a market guarantees that the match mechanism leads to the best possible result boys are more willing to participate in this market. \subsection{Market for New Economics}Alvin Roth is the first one who finds application of Gale and Shapely in real world market. The first time that he found Gale and Shapely algorithm’s application was in 1984 in the job market for new doctors. He proves that since 1951 deferred acceptance algorithm has been used in matching new doctors to hospitals.\\New doctors have to pass two years of internship after their graduation, which is called residency. Residency provides a crucial workforce for hospitals and consider as an important period that influence future doctors career. Hence, there is a fierce competition among hospitals to hire medicine students graduate. From 1900 to 1945, there had been competition among hospitals for hiring residence. As a result hospitals offered position to students two years before students’ graduation.\\Today we know that this market suffered from unraveling, which is a common and costly type of market failure. This implies that, students had to make decisions before having perfect information about their preferences and hospitals quality. Hence, students were not able to make the best possible decision. \\Marker design economics have discussed problem of unraveling and propose several solutions for it (several refrences). For instance, Roth and Xing (1994) note that as in thirteenth century unraveling can be eradicated by not allowing transaction before goods are offered in a market. After 1945, in order to avoid unraveling, American medical schools released students’ information just one year before graduation. Consequently, a new problem arises; if most preferred students rejected hospitals’ offer, the other candidates might accept offers of other hospital. That is, the market did not guarantee that the hospitals and student find their most preferred matches. Moreover, there was a risk of not finding enough residences for hospitals. Hence, hospitals proposed to abundant numbers of students. The reason for that was hospitals want to ensure that they will reach as many number of students as possible. This leads to congestion that is another forms of market failure.  \\ Markets difficulties and failures brought hospitals, students, and schools together to solve the current market failures. Therefore, they designed a centralized clearinghouse to improve market coordination. The clearinghouse system works in the following manner, in the first round students apply and hospitals will interview with the students. Afterwards, students rank the hospitals that they have interviewed and hospitals will also rank the students that they have interviewed. Finally, a centralized clearinghouse, which is called today National Resident Matching Program (NRMP), matches hospitals and students. \\In 1984 Roth prove that the National Resident Matching Program (NRMP) employs deferred preference algorithm, which is created by Gale and Shapely (1962), and it always result in a stable match. This suggests, under the current match system there are no student and hospital that prefer mutually to match together but they do not. In other words, there is no pair of student and hospital that can break the resulted match. Roth further shows that 95 percentage of matches in this market is done by clearinghouse and particularly by deferred acceptance algorithm.  \\One might suggests that the successful match can be the result of any algorithm and not merely deferred acceptance algorithm. Roth 1990 and 1991 launch a study in England and compare the different region that apply different algorithm. He finds that the centers that apply deferred acceptance algorithm produce stable matching and keep the algorithm for a long period. In contrasts, the other centers that use other kinds of algorithm create instable match. In the same token, Kagel and Roth, in lab experiment, prove the hypothesis that deferred acceptance algorithm eliminate unraveling, however, other algorithm produce unraveling matches. \\This examples suggests that, centralized clearinghouse is a solution for unraveling, which is one of the costly form of market failure. Furthermore, deferred acceptance algorithm leads to stable match. \subsection{Kidney Exchange}Kidney transplantation is the final remedy of patients with diseases related to kidney. Moreover, the life of many kidney patients depend on kidney transplantation. Healthy people can give one of their kidneys. However, due to rules and regulation kidney purchasment and sell is forbidden. Moreover, the main problem for kidney donation is that the blood type and the immune system of patient are not compatible with patients. Alvin Roth with respects to market limitations design a mechanism that facilitate transactions in this market. \\In the Unites States of America, more than 70,000 patients are in the waiting list for a deceased donor. Nevertheless, only 11,000 receive a kidney. The result is that above 5000 patients died while they are in the waiting lists for a compatible kidney. The same situation holds in other parts of the worlds. For illustration, in UK 6000 renal patients are in the waiting list for a transplantable kidney, nonetheless, only 1240 have the chance to operate a transplantation surgery.\\Healthy people also can donate one of their two kidneys to renal patients. Moreover, kidney transplantation from a healthy body is by and large more helpful for the patients than cadaver kidney transplantation. However, the donation of kidney requires compatible blood type and immune system. \\There is an excess of demand in kidney market, however, due to legal system of all countries, it is illegal to buy and sell kidney. The reason behind that is, most of the societies show repugnant toward transaction of some specific goods (Roth 2007). \\Alvin Roth indicates that the task of economists as a market designer is to create a mechanism that facilitate and increase transactions, given present legal restrictions and social repugnance in the market. \\There are two possible ways to increase number of transactions in this market, given the current legal rules; primo, the exchange of kidney between donor-patient pairs (Footnote: patient-donor pair, a donor who wants to give his kidney to a patient). To understand it, assume two patient-donor pairs, donor A want to donate his kidney to patient A, and donor B wants to donate his kidney to patient B. Kidney of donor A is not compatible with patient A and the same hold for donor-patient B. Nevertheless, donor A has a compatible kidney with patient B and donor B has a compatible kidney with patient B. It is possible that a donor A donate his kidney to the patient B in exchange for donor B donate his kidney to patient A. \\Secudno; the other possible exchange is between a donor-patient pair and a patient who is early in the waiting list of a cadaver kidney. Again, assume donor-patient pair of A and patient B who is early in the cadaver kidney waiting list. Donor A donates his kidney to patient B, and cadaver kidney is given to the patient A. \\In spite of the fact that both forms of exchange are feasible and are in aligned with social norms these sorts of exchange are rarely happened. For example, only 5 exchanges had been occurred in 14 transplant centers in New England. \\There are several factors that explain why exchange has been so rare, or the kidney market has failed to exchange kidneys. The most dominant cause of the market failure is that the market is thin. That is to say, there are not enough incompatible patient-donor candidates for an exchange in the market. Furthermore, when a compatibility test reflects that donor kidney does not match to his patient, doctors send a way donor without recording the information of donor. Besides that, in case that donors’ information is available, due to medical regulations and privacy rules it is not possible to have an access to the information.\\Roth, Sönmez, and Ünver (2004a) prove that a centralized clearinghouse that gather database of incompatible donor-patient pairs make kidney transactions more feasible. This means, the more information about different donor-patient pairs the easier to find match between different patients and donors. Furthermore, they show that there is no restriction in sizes of pairs. That is, the system can match as many pair as possible. The reason for that is, there will be a cycle of kidney exchange where a first pairs will give to the second pairs and a second pairs give to the third and third will give to the four and so on. This cycle will continue till the cycle closed, and last pair donate to the first.\\ Roth and his colleagues send this idea to many kidney surgeons. As a result, one of the surgeons (who is the medical director of the New England Organ Bank) accepts the idea and brought the idea to 14 kidney transplant centers in New England. In these centers they use the matching software that is designed by Roth and his colleague. In the beginning the logistical limitation limit exchange to maximum of two pairs. That is, there is a need for simultaneous operation of two pairs, 4 operations in the same time. The reason for simultaneous operation is to ensure that donors wont change their idea. After years, the matches extended to three pairs and also several transplantation centers applied the software clearinghouse( refrence).\\In summary, the kidney market was failed due to the lack of market thickness. The market fails to bring what Jevons called double coincide of wants (Jevons 1876). A centralized clearinghouse that entail database of donor-patient pairs increases the numbers of kidney exchange. \subsection{School Choice}This is an example of markets where money does not influence the transaction. The school select annually number of students based on specific criteria. Students have some specific preferences and there are also admission requirements from school side. Market thickness is not a problem here, since government provides supply side in according to number of students. The performance of school choice systems depends on two facts; firstly, quality of dealing with congestion; secondly, makes it safe for participants to reveal true preferences. New York City (NYC) education system suffers from congestion, hence, NYC education department ask Roth and his colleagues to redesign the education choice system. A centralized clearinghouse solves the problem of NYC education system. Formerly, Boston education choice system does not make it safe for students to reveal their true preferences and Roth has successfully redesigned the system and solve the problem (Chen and Sonmez (2006), Ergin and Sonmez (2006), Pathak and Sonmez (2008), and Abdulkadiroglu et al. (2007)). In the following it will be explained that how a system can leads to congestion and make it risky for participants to reveal their preferences. Furthermore, the solution for these problems will be explained.\\In NYC around 90,000 students have to be assigned to 500 high school program. The old system match students with schools in the following manner;First, students filled out a rank order list and only mentioned the top five schools that they prefer them the most. Second, the preference’s list was sent to the five schools. Third, schools could make three decisions; accept, reject, and put the students in a waiting list. Fourth, the result was sent to the students. Fifth, students accepted one choice and inserted one of the choices in waiting list. Sixth, Schools that still possess empty positions sent new offers. This process repeated only three times and afterwards those students who did not get admission from any schools were assigned to zoned schools or assigned in an administrative process. \\The market suffered from several sever problems. First of all three rounds of process were not sufficient to allocate 90,000 students, who make 5 choice over 500 potential options. This suggests that market fails due to the congestion (Roth and Xing [1997]). Consequently, only 50,000 receives offer and top 17,000 students secured with several offers. Moreover, more than 30,000 students assigned to the school hat were not in their preference list. \\Three issues motivated NYC education department to call Roth for redesigning the choice system; primo, 30,000 students who were assigned to the schools that they were not prefer it. Secundo, students rank the schools strategically. That is to say, students filled in preferences list untruthfully. Students ranked the schools that were most likely got admission from and not preferred it the most. The reason for that was, students thought that schools took the preferences lists into consideration for admission. Tertio, schools played strategically and did not revealed their actual capacity to NYC department of education. Schools afraid that their positions will be filled in by students who came unwillingly and are rejected from the other schools. (The school after cleaing house reveal their true prefercnes because thy make sure that the NYC education department wont allocate unsatisfactory students to their schools).  \\Exercising centralized clearinghouse contribute to the quality of choice system. First of all, it overcome congestion problem: specifically, number of students who assigned administratively reduce from 30,000 to 3,000. Secondly, after three years of implementation schools learned that, it is not profitable to hide the capacity. That is to say, the new system guarantee that schools’ positions are filled in by students who prefer schools the most. That is, the new system ensures that the match is the best possible match. The last but not the least, as the preferences list was filled in honestly and truthfully; the data use for several political research and decision-making process. For instance, it has been used to identify the low quality schools. Abdulkadiroglu, Pathak, and Roth 2005, 2007). \\( The question is how they make students to reveal their true prefernces truethfully and how they make the schools to show the truth capcit ? If we can solve this we can show that how a centralized matching house can also overcome principle agent problem. \\That is to say, since computers are a trusted intermediaries both parties will trust it and provide the ture information to it. Furthermore, they cannot hide It anymore, But how you can make schools to reflect their true capacity??) The answers are all in Abdulkadiroglu, Pathak, and Roth 2005, 2007) \\In Boston the drawback of old system was that it make it risky for families to unveil their preferences, if it was not their local school. The old system worked in the following manner; in the first place parents rank their schools. Afterwards, an algorithm in Boston education system tried to assign as many students as possible to their first choice. If there was an excess of demand for a school, the numbers of students that apply for a school exceed available positions in a school, then the algorithm will prioritize those who have siblings, live in a same location, or are lucky and have a good lottery number. In the next step all of the students who were not assigned to their first choice will be assigned to their second preferences. The process will continue to the third rank of preferences and so on.\\The drawback of this system was that families always feared that if they were rejected from the most preferred schools other schools are filled by students who ranked them as a first choice. In other words, they afraid that they would not get admission form a school if they rank it in second position. Therefore, families confronted with difficult strategic decision and had to spent substantial resource to gather information about capacity of school, and regulation and so on. The other issue with the old system was that, majority of students ended up with the schools that they like them the list but, due to inefficient system, rank them the first.\\In Boston, schools do not play a role in making the final choice. This make the designing much more easier, since there are broader possible matching system. Roth and his colleague propose two possible systems that make revealing the true preferences the dominant strategy for students and their families (Abdulkadiroglu et al. 2005, 2007). They utilize deferred acceptance algorithm and “top trading cycles” algorithm, that was discovered by Shapely and Scarf in 1974. The algorithms proven to be strategy-proof, in the case of schooling problem this implies that for families it is dominant strategy to reveal their true preferences (Abdulkadiroglu and Sönmez (1999, 2003). Therefore, Roth and colleague advice Boston education department to adapt a form of deferred acceptance algorithm. \\In summary, the old schools choice system made it unsafe for the students to unveil the preferences. Concealing information is a common and costly form of market failure. A clearinghouse and the algorithm transparent the market. As a result, providing the true information becomes dominant strategy for families. \subsection{Gastroenterologists}American medical students who aimed at becoming a gastroenterologists have to pass three years of residency in internal medicine and then apply for a gastroenterology fellow position. From 1986 to 1990 a stable clearinghouse had been used to assign resident to gastroenterology fellow.  Nevertheless, at the beginning of 1991 this centralized system was replaced by a decentralized matching market. The consequence was the emergence of unraveling in the market. The gastroenterology institutions’ offers were scattered in the year and they shorten the period of response. Furthermore, gastroenterology institutions’ offers to student reached to two years before student enter into the job market. These caused thinness of market and most of the students continue to work as a gastroenterologists in the hospitals where they were residences. \\These issues created a common consensus, among various organizations that involved in gastroenterology market, that the clearinghouse should exit one year before accomplishment of residency period. \\The problem that arise was that program directors who ask for recreation of clearing house afraid that the other gastroenterology organizations do not use the clearinghouse and offer students again in two years in advance. As a result, they discussed their concerns with Roth and his colleagues. Alvin Roth proposes that some regulations have to be enforced in order to disincentivize applicants and employer to transact outside of the clearinghouse.  Roth and Niederle 2008, in lab experiments, test the impact of rules on the time of agents’ offers and applicants response. They propose that the matching should be occurred in 15th of April. Moreover, they propose to enforce the following policy; any working agreements with residence before the 15th of April can be terminated. Nevertheless, residences are responsible for the working agreement that are made after 15th of April and no party can break an working contract without having agreement of both sides (http://www.cgsnet.org/ portals/0/pdf/CGSResolutionJune2008.pdf).\\Four major gastroenterology professional organizations accept to implement the policy; American Gastroenterological Association, the American College of Gastroenterology, the American Society for Gastrointestinal Endoscopy, and the American Association for the Study of Liver Diseases. Their resolution ensure that the applicants and position will remain till the match and there is no need to rush and make a contract before the match take place.\\Resolution aimed at: make it unattractive for program director to offer in advance. Moreover, nudge applicants to do not accept early offers(refrence: Website).\\As a result, 79\% of fellowship programs participate in the matching clearinghouse. Form the participants 98\% match through the clearinghouse. This implies, the new rules make it safe for players in the market to participate in the match. Furthermore, the problem of timing, dispersed offers through the year, and congestion have been solved by clearinghouse. \\This example illustrates that, for clearinghouses to work effectively sometimes there is a need to impose rules and implement force. In many cases, clearinghouse is a solution for market failures. However, there are agents who benefit from decentralized and opaque market. These agents are not willing to participate in clearinghouse or other mechanisms that transparent the market. In this situation, a physical clearinghouse by itself won’t make much change in the market. There is a need for using force and regulating the market. In these cases professional Gastroenterology organization seat together and enforce the rules.\\ However, in case of BOP private agents have to convince governments to enforce the rules that help clearinghouse to work and leads to market failure. \subsection{Market for New Economics}Job market for new PhDs is decentralized and open market. This means that, PhD graduates apply for several institutes separately and institutes consider the applications independently. Moreover, the market for PhD graduate is not concentrated in a geographical location and it spread over many different countries. \\In North America this market suffered from two sources of market failure. The main problem was adverse selection, this implies, institutions that offer jobs were not ensure that applicants consider the position certainly. Usually, applicants considered some positions as their default options and were not interested on the position. The other problem was congestion; the system in North America was designed in a manner that it triggers congestion in the market. In the following, first the structure of the job market and its problems will be explained. Afterwards, it will be elaborated how a central signaling system solve the adverse selection problem and a centralized market overcome the congestion.  \\The job market for new PhDs is decentralized, however, there are some centralized institutions that operate in this market such as American Economics Association (AEA). The job market structure is as following: in the early fall job seekers can see the advertisement of institutions in economics monthly magazine of economic associations (for example see (http://www.aeaweb.org/joe/). PhDs students send their application and reference letter to institutions. As a result, department receives hundreds of application in late fall. They have to go through all details of the applications and make a selection for 30 minutes interview that hold in large meeting in early January. This meeting consists of 51 associations and takes place in a hotel and applicants have an interview with department in suits. Department have to reserve suits two months in advance. Recruiting teams interview candidates one after another and candidates up and down the flours and have several meeting in a day. \\After a meetings in early January some the candidates will be selected for the “fly out”. That is, a day where candidate will meet faculty member and dean. \\The result of this system is that by the end of March market faces thinness problem. For instance, departments interview with 20 applicants, and invite 6 of them to fly out day and offer two of them the position. In case that the two applicants reject the offers, departments have to look at all of the applicants and start all of the procedure again to find a suitable candidate. The same problems hold for applicants, if they were rejected in the last step they have to search for new department. This indicates how costly is adverse selection for the institutions. \\AEA by creating a central signaling house overcome partly the adverse selection problem. Students have to send a list of their preferred departments and their profile to AEA. AEA transmits only two recommendation letters to two departments. Due to the fact that the signaling was limited it provides valuable information. Furthermore, it overcomes the congestion problem, because of the fact that only limited numbers of applicants will be sent to the interview.\section{e-Choupel}Backward farming technology and inability in weather prediction leads to shortage of food in post independence India. Consequently, politicians aimed at finding a solution to the food shortage and insecurity. This results in “green revolution” in India. As part of this plan, the Indian government decided to distribute farms to the end cultivator. The ideology beside this was to make farms more productive and redistribute wealth to the poor. Nonetheless, the farms become too small to become profitable and farmers became extremely poor. \subsection{Oil Seed Complex}Edible oils are the crucial part of Indian kitchen. The oil seed complex is crops that produce oils. In 1970s there was excess of demand for oilseed in India, combining with inefficient agriculture sector, the result was that 32\% of oilseed were imported from other countries. Dependence on imported food brought insecurity in the food provision and large variance in foods’ price. In order to bring independency in the oils, protectionism brought profit into oilseed cultivation. Hence, the production doubled in a short period. Furthermore, farmers cultivate two new oilseed, namely; sunflower and soya bean, and thy account for 40\% of oilseed production. These two oilseed are mainly processed in crushing factories. As a result, it is crucial for farmer to sell this to the traders that have link with crushing factories. \subsection{Marketing Chanel}Agricultural Products Marketing Acts creates, a governmental agency that is called, Mandi with the aim of more equitable distribution of grains among consumers, and traders. Each Mandi approximately covers 700 square kilometers. Farmers bring their productions to Mandis and traders purchase products in Mandis place. Hence, they are the key in bridging demand and supply of oilseed, especially for Soya where the main use is for crushing company.\\There were three ways for farmers to sell their products: Mandis, traders that distribute the product to the crushers, direct sale to crushers. Selling through Mandis and traders account for 90\% of the transactions in the market.\\In each Mandis there are two Commission agents that are responsible for lunching the trades. \subsection{Mandi Value Chain}        \begin{table}[h]        \begin{tabular}{l| C{3cm} | C{3cm} | C{3cm} }                Value Chain Steps  & Description & Inefficiencies & Market Failure \\                \hline                Inbound Logistic    & \textbf{Farmers choose one of the nearest Mandis and transportl their products to Mandi Place.} & \textbf{1-Farmers do not have a resource to analyze the price before trasnporting the products to Mandi.

Mandi is an example of an inefficient agent that causes failure of agriculture market. For example, before Mandi in one of the Indian village there were 100 percent soybean production, nevertheless, afterward it reduces to 50%. \\Mandis and middlemen in the market distort the information transformation from crusher companies to farmers. That is, Mandi do not explain to farmers what types of quality a crushing company needs. As a result, farmers do not know how to improve the quality of his production. In addition, due to instability in purchase there was large price variation in products’ prices.\subsubsection{e-Choupel}An Indian conglomerate, which diversified into agribusiness and information technology, aimed at entering to oilseed sector. ITC called its mangers to utilize the new technology in a way that they overcome to the problems in the current oilseed market. Consequently, mangers and IT men in the ITC came up with centralized information centre that connect farmers to the Internet and provide with information about price of products and its trends. \\As Roth says, the evolution of markets are from auction to the matching market and the ITC system can be seen as a bridge that bring this market toward matching. Farmers do not need anymore to participate in the auction to sell their products; they can check the price of products in different Mandis, in different markets in the world and its trend. Hence, they choose to whom to sell and match their products with one buyer. \\The new systems solve the problems of unraveling, congestion, and asymmetric information. ITC centralized information house (e-Chouple) provide complete information for farmers. Hence, farmers decide with complete information, hence, the past problem of unraveling was solved. Moreover, farmers do not need to sleep in a queue to ensure they will be the first their products, as a result, the congestion was overcomed. Finally, with advance technology ITC were able to precisely estimate the quality of the products, therefore, the asymmetric information reduce between the two parties. \\e-Choupal is the traditional name of a place in the village where people gather. e-Couple is computers that is located in the Snanchalaks’ house, that provide a centralized information centre for farmers. e-Chouple are in distance of max 5 kilometers to the farmer. It covers more than a million farmers and in 11,000 villages and 2000 kiosk across 4 states. \\Snachalak means farmer, and is a farmer in village that run the local e-Chouple. That is, in each village a computer install in the house of Sanchalak and they were responsible for estimating the quality of village’s product.There were two reasons that ITC use a local farmer as a commissioner. First of all, in Indian’s villages the contract’s costs are high because of difficulty in enforcement of contract. Hence, ITC hire a local farmer that the other farmers trust him. Consequently, other farmers trust ITC Commissioners. Besides that, ITC reduce the cost of purchasing a building and its maintenance in several villages.\\ITC creates continues flow of money to Sanchalak through a unique system. That is, Sanchalaks have incentive to work in aligned of ITC’s interests. Sanchalak get a commission for each sets of products that its detect. ITC determines sets of products that divide into four different seasons. In this system, Sanchalaks earn money all of the year and this position become attractive for him.\subsection{e-Choupel Value Chain}\includegraphics[scale=0.5]{6}\section{Conclusion}Prahalad notifies that extension of market into the BOP is crucial for poverty eradication. Management science has been dominant in BOP literature. This paper try to utilize economic theory to further enrich BOP literature. \\In this paper it is discussed that, the poor active involvement in the production value chain and consumption is a powerful tool for poverty eradication. Hence, there is a need for involvement of large-scale entrepreneurs in the poor market. However, institutionalists rise the point that in the case of high transaction cost entrepreneurial growth is unlikely and large-scale companies show reluctant in involvement in BOP market. There is a common consensus that transaction costs are high in BOP market.  Market design economics is an emerging field in economics that entails a solution for transaction costs and market failures. In this paper it is that how a clearinghouse overcome market failures. Furthermore, this paper ends by the example of a firm in BOP that apply clearinghouse. As it can be seen from the example, the clearinghouse change the life of the poor farmer and gives a birth to the oilseed complex in India.\\This paper suggests that Market Design and Transaction Costs can provide a robust theoretical framework to further enrich BOP studies. Connecting these two fields can contribute to both specialties.\\Roth believes that the maturity of market design economics requires accumulation of experience in several markets. Market design economists have to further investigate other markets and explain in detail complexity, result, and failure of markets. The next generation of authors should not focus on game theory and absolute mathematical models, the development of this field requires transferring audience from publishment’s judge to the society and participants of several markets. Furthermore, currently BOP literature does not have a robust theoretical framework.….  \\Long steps have to be taken in order to analyze the implication of market design economics into the BOP field. As Roth said the evolution of markets are from auction to matching market.  Development of algorithm that can be used in the BOP market can significantly improve the structure of the market. Furthermore, market design economics maybe able to faster the pace of the poor involvement into the production value chain and customer.  \bibliographystyle{apacite}\bibliography{Bibdesk}\end{document}
