indirect effects of an aid program how do cash transfers affect ineligibles consumption cash transfers to eligible households indirectly increase the consumption of ineligible households living in the same villages this effect operates through insurance and credit markets ineligible households benefit from the transfers by receiving more gifts and loans and by reducing their savings thus the transfers benefit the local economy at large looking only at the effect on the treated underestimates the impact one should analyze the effects of this class of programs on the entire local economy rather than on the treated only and use a village level randomization rather than selecting treatment and control subjects from the same community

the influence of motivations and environment on business start ups some hints for public policies abstract this paper examines entrepreneurial motivations to start a business in different perceived environmental settings motivations to start a business for a sample of 163 entrepreneurs from growing and declining regions in the north center and south of italy were factor analysed in order to identify the main groupings of variables that lead people to start their own business the results proved to be highly consistent with friberg s 1975 1976 findings on incentives to start a business the motivation factor scores were then clustered and three verv different classes of entrepreneurs were identified each driven by very different sets of motivations self actualizers who started their business driven by a thirst for achievement and a sense of independence and autonomy discontented entrepreneurs unhappy with present working conditions and followers of family tradition role models the relationship between individuals motivations and their perceptions of the environment was then investigated resources and incentives to start a business were factor and cluster analyzed to yield three very different types of perceived environments munificent environments characterized by efficient infrastructures established capital markets and the availability of incentives to start a business supportive environments in which the creation of an infrastructure specifically aimed at encouraging new companies could lead to a significant increase in entrepreneurship sparse environments lacking both infrastructure and capital availability the proportions of entrepreneurial types differ significantly in each environment government intervention in stimulating the diffusion of entrepreneurship is legitimized by the role new companies play in job and wealth creation and the diffusion of innovation within a territory these results suggest some implications for public policies instead of blanket incentive policies applied on a wide geographical basis policies tailored on a local basis may be more effective in stimulating new venture creation

intra firm bargaining under non binding contracts we present a new methodology for studying the problem of intra firm bargaining based on the notion that contracts cannot commit the firm and its agents to wages and employment we develop and analyse a general non cooperative multilateral bargaining framework between the firm and its employees and consider outcomes which are immune to renegotiations by any party equilibrium firm profits are characterizable as both a weighted average of a neo classical non bargaining firm s profits and a generalization of shapley value for a corresponding cooperative game furthermore the resulting payoffs induce economically significant distortions in the firm s input and organizational design decisions

risk and insurance in a rural credit market an empirical investigation in northern nigeria credit contracts play a direct role in pooling risk between households in northern nigeria repayments owed by borrowers depend on realizations of random shocks by both borrowers and lenders the paper develops two models of state contingent loans the first is a competitive equilibrium in perfectly enforceable contracts the second permits imperfect information and equilibrium default estimates of both models indicate that quantitatively important state contingent payments are embedded in these loan transactions but that a fully efficient risk pooling equilibrium is not achieved the research is based on a year long survey in zaria nigeria conducted by the author

explaining micro entrepreneurship in rural vietnam a multilevel analysis in the literature on entrepreneurship there is an ongoing debate about the impact of regional factors on the entrepreneurial process to date most of the empirical work on the influence of regional characteristics on entrepreneurship has focused on developed countries while empirical work that analyses the regional determinants of micro entrepreneurship in rural areas of emerging markets remains scare this paper uses three level binary logistic random intercept models to analyse the effects of explanatory factors at different levels on micro entrepreneurship in rural vietnam our analyses show that identifying the motivation behind starting a micro enterprise is a good way to split entrepreneurship into two groups namely opportunity and necessity driven entrepreneurship which are influenced by very different explanatory factors at different levels we find evidence that in rural areas of emerging markets the individual level dominates with regard to explaining both opportunity and necessity driven entrepreneurship nevertheless the regional level has a significant impact albeit only on opportunity driven entrepreneurship

optimal linear income taxation in models with occupational choice the purpose of this paper is to investigate the implication of occupational choice for linear income taxation occupational choice is restricted to entrepreneurship versus wage earning different settings are considered concerning the introduction of uncertainty and that of individuals heterogeneity in ability or risk aversion for each setting an optimal tax formula is derived and shown to be made up of various components pertaining to insurance redistribution and efficiency

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

the third sector and the regional development of social capital birch k and whittam g the third sector and the regional development of social capital regional studies there is a growing academic and policy interest in the third sector and its potential impact on regional development a key aspect of the third sector is its role in regional development through the promotion of social capital however there is considerable debate around the definition of the third sector that limits one s understanding of its impact the paper first disentangles a number of ambiguities to clarify the distinctions between the concepts before then exploring the relationship between the regional development of social capital and the various aspects of the third sector finally uk policy agendas and initiatives are considered in light of the earlier discussion birch k et whittam g le secteur tertiaire et le developpement regional du capital social regional studies le monde universitaire et la politique s interessent de plus en plus au secteur tertiaire et a son impact potentiel s

corruption and destructive entrepreneurship the negative effects of corruption at the macro level are well documented corruption reduces economic growth lowers investment and erodes trust in government officials creating an institutional environment that pushes entrepreneurs from productive to destructive activities corruption also has effects at the micro level because some industries are better situated to profit from corruption than others corruption not only lowers economic output but also shifts resources toward some industries and away from others using federal convictions in the usa as a measure of corruption regression results show that increased corruption shifts resources toward the construction industry and away from the education industry and professional scientific and technical service industry the evidence also shows that the distance from state capitals and voter turnout moderate the relationship between corruption and firm concentrations

regional social capital why it matters malecki e j regional social capital why it matters regional studies social capital refers to a culture of interaction among people with productive economic outcomes social capital promotes regional learning both within a region and beyond as it reinforces openness to the ideas of others regional cultures vary in the degree to which people individually and within their organizations trust and interact with one another which is why regional outcomes vary innovation learning and entrepreneurship key processes of regional development take place largely within and among people as members of companies and territorial organizations innovative milieus industrial districts and knowledge economies are among the regions with extraordinary pools of social capital malecki e j

local social capital and entrepreneurship we aim to contribute to the analysis of the role that spacebound social capital plays in local regional entrepreneurship we compare social capital with other forms of capital the conclusion is that in the main social capital can be analyzed in the same way as other capital but it has some important special attributes with these attributes as starting point we sketch an outline model of how the spatially defined producer surplus and consumer surplus form a place surplus and of the role played by social capital in the creation of the producer surplus a rereading of schumpeter shows that he was aware of several aspects of what we denominate entrepreneurship inhibiting and facilitating aspects of social capital finally we discuss some formal economic modeling approaches to the theoretical relationship between social capital and entrepreneurship

fractionalization entrepreneurship and the institutional environment for entrepreneurship the vast majority of the literature on ethnicity and entrepreneurship focuses on the construct of ethnic entrepreneurship however very little is known about how ethnic heterogeneity affects entrepreneurship and the institutional arrangements affecting entrepreneurship this study attempts to fill the gap and thus examines the effect of ethnic heterogeneity on various outcomes associated with entrepreneurship and the institutional environment for entrepreneurship using indices of ethnic and linguistic fractionalization we show that ethnic heterogeneity negatively influences entrepreneurship we argue that potential channels that can explain the negative effect of fractionalization on entrepreneurship include trust social network and innovation among others this study provides a new perspective on the existing debate that seeks to understand why the levels of entrepreneurial success vary across countries

panel studies of new venture creation a methods focused review and suggestions for future research longitudinal panel studies of large random samples of business start ups captured at the pre operational stage allow researchers to address core issues for entrepreneurship research namely the processes of creation of new business ventures as well as their antecedents and outcomes here we perform a methods orientated review of all 83 journal articles that have used this type of data set our purpose being to assist users of current data sets as well as designers of new projects in making the best use of this innovative research approach our review reveals a number of methods issues that are largely particular to this type of research we conclude that amidst exemplary contributions much of the reviewed research has not adequately managed these methods challenges nor has it made use of the full potential of this new research approach specifically we identify and suggest remedies for context specific and interrelated methods challenges relating to sample definition choice of level of analysis operationalization and conceptualization use of longitudinal data and dealing with various types of problematic heterogeneity in addition we note that future research can make further strides towards full utilization of the advantages of the research approach through better matching from either direction between theories and the phenomena captured in the data and by addressing some under explored research questions for which the approach may be particularly fruitful

core and periphery in networks abstract we study a model of network formation where the benefits from connections exhibit decreasing returns and decay with network distance we show that the unique equilibrium network is a periphery sponsored star where one player the center maintains no links and earns a high payoff while all other players maintain a single link to the center and earn lower payoffs both the star architecture and payoff inequality are preserved in an extension of the model where agents can make transfers and bargain over the formation of links under the condition that the surplus of connections increases in the size of agents neighborhoods our model thus generates two common features of social and economic networks 1 a core periphery structure 2 positive correlation between network centrality and payoffs

determinants of trust in supplier relations evidence from the automotive industry in japan and the united states abstract this study examines the determinants of inter organizational trust by using survey data from over 1000 suppliers in the automotive industry drawing on transaction cost economics game theory and sociological exchange theory we define trust and derive a model of its determinants regression analysis results indicate that determinants of trust are different from determinants of opportunism us japanese differences are found in three respects i the way trust is conceptualised by suppliers is more complex in japan than in the us ii the level of trust is higher in japan than in the us and iii the factors facilitating trust and those attenuating opportunism differ in the us and japan

risk sharing across communities this paper studies cross community risk sharing there is now a large body of theoretical and empirical work on informal insurance where people mitigate risk by sharing income a consistent empirical finding is that risk sharing is not complete within villages often the observed sets of individuals 2 one reason researchers suspect is that risk sharing does not take place at the village level but between individuals and families 3 we build a theoretical model where risksharing takes place between pairs of agents there are idiosyncratic shocks to individual income and community level shocks we consider how the opportunity for cross community links affects the shape and efficiency of risk sharing arrangements we find that when links across villages form there can be less risk sharing within a village welfare is higher for those directly or indirectly connected across villages but lower for those with no path connecting them to the other village overall welfare can be higher thus empirical findings that insurance within a village is not complete is not necessarily evidence of an inefficient pattern of risk sharing relations rather the finding is consistent with risk sharing patterns that involve cross community relations and such patterns may yield higher aggregate welfare despite incomplete insurance within a village this paper makes two contributions first it demonstrates the importance of a network analysis by examining pairwise incentives to form relations and the resulting pattern we can see new risk sharing outcomes second with this network model we show how informal risk sharing across communities has both aggregate and distributional effects to study network outcomes we posit a simple two stage model first we provide a benchmark model for risk sharing for a given network then working backwards we consider incentives to form risk sharing links 4 to illustrate consider a rural population and ask how people might link

entrepreneurship and the intergenerational transmission of values there is mounting empirical evidence that there is intergenerational transmission of parental preferences for entrepreneurship however much of the work on this topic is not explicit about the role of values in this transmission process furthermore nearly all studies neglect potential heterogeneity of values among entrepreneurial parents this paper contributes to the literature by making use of a natural experiment that allows 1 identifying a group of entrepreneurial parents who have a distinct priority of challenging existing conditions mastery and 2 detecting whether this value orientation is transmitted comparing german entrepreneurs two decades after reunification reveals that the children of self employed parents who encountered a great deal of resistance in the socialist german democratic republic due to their self employment are much more likely to give mastery as the reason for running their own venture compared to entrepreneurs whose parents did not have to overcome this sort of challenge

bidding for surplus in network allocation problems in this paper we study non cooperative foundations of network allocation rules we focus on three allocation rules the myerson value the position value and the component wise egalitarian solution for any of these three rules we provide a characterization based on component efficiency and some balanced contribution property additionally we present three mechanisms whose equilibrium payoffs are well defined and coincide with the three rules under consideration if the underlying value function is monotonic non monotonic value functions are shown to deal with allocation rules applied to monotonic covers the mechanisms are inspired by the implementation of the shapley value by perez castrillo and wettstein bidding for the surplus a non cooperative approach to the shapley value j econ theory 100 2 2001 274 294

bargaining in stationary networks we study an infinite horizon game in which pairs of players con nected in a network are randomly matched to bargain players who reach agreement are replaced by new players at the same positions in the network we show that all equilibria are payoff equivalent the payoffs and the set of agreement links converge as players become patient several new concepts mutually estranged sets partners and shortage ratios provide insights into the relative strengths of the positions in the network we develop a procedure to deter mine the limit equilibrium payoffs for all players characterizations of equitable and nondiscriminatory networks are also obtained jel c78 d85 competitive equilibrium theory assumes large and anonymous markets in which every buyer can trade with every seller underlying these assumptions are standard goods and services that may be traded at low transaction costs by agents who are not in specific relationships with one another however in many markets goods and services are heterogeneous e g cars apartments or need to be tailored to particular needs e g manufacturing inputs technical support furthermore trad ing opportunities may depend on transportation costs social relationships infor mation advertising trust technological compatibility joint business opportunities free trade agreements etc in such cases it is natural to model the market using a network where only pairs of connected agents may engage in exchange new theories are needed to explore the influence of the network structure on market outcomes many questions arise how does an agent s position in the net work determine his bargaining power and the local prices he faces who trades with whom and on what terms when are prices uniform in the network one possible conjecture is that an agent s bargaining power is determined by his relative number of connections in the network however this simple theory is implausible consider the network of four sellers located at the top nodes and nine buyers located at the bottom nodes depicted in figure 1 assume that each seller supplies one unit of a homogeneous indivisible good each buyer demands one unit of the good and all buyers have identical values for the good the buyer located in the middle has the largest number of links in the network as he is connected to each

measuring enterprises investments in social capital a pilot study westlund h and nilsson e 2005 measuring enterprises investments in social capital a pilot study regional studies 39 1079 1094 research into the impact of social capital on economic growth has focused mainly on the social capital related to the civic society social capital related to business enterprises has received little attention this pilot study aims to develop a method of measuring investment by enterprises in social capital and to study possible connections between the enterprises investments in social capital and their economic growth based on a network approach the paper makes a distinction between the networks links and the norms values etc that are created and sustained by the nodes i e the enterprises and other actors and distributed via the links the study has been limited to measurement of the links three types of link are analysed 1 direct investment in social links 2 investment in economic links forming the basis of social links and 3 investment in social li

structural holes in social networks we consider a setting where every pair of players that undertake a transaction e g exchange goods or information creates a unit surplus a transaction can take place only if the players involved have a connection if the connection is direct the two players split the surplus equally while if it is indirect then intermediate players also get an equal share of the surplus thus individuals form links with others to create surplus to gain intermediation rents and to circumvent others who are trying to become intermediary our analysis clarifies the interplay between these forces in the process of strategic network formation first we show that in the absence of capacity constraints on links it leads to the emergence of a star network where a single agent acts as an intermediary for all transactions and enjoys significantly higher payoffs second we study the implications of capacity constraints in the ability of agents to form links in this case distances between players must be long which induces players who are far off to connect in order to avoid paying large intermediation rents a cycle network then emerges payoffs being equal across all players

against parsimony three easy ways of complicating some categories of economic discourse economics as a science of human behavior has been grounded in a remarkably parsimonious postulate that of the self interested isolated individual who chooses freely and rationally between alternative courses of action after computing their prospective costs and benefits in recent decades a group of economists has shown considerable industry and ingenuity in applying this way of interpreting the social world to a series of ostensibly noneconomic phenomena from crime to the family and from collective action to democracy the economic or rational actor approach has yielded some important insights but its onward sweep has also revealed some of its intrinsic weaknesses as a result it has become possible to mount a critique which ironically can be carried all the way back to the heartland of the would be conquering discipline that the economic approach presents us with too simpleminded an account of even such fundamental economic processes as consumption and production is the basic thesis of the present paper this abstract was borrowed from another version of this item

consumption smoothing migration and marriage evidence from rural india a significant proportion of migration in low income countries particularly in rural areas is composed of moves by women for the purpose of marriage we seek to explain these mobility patterns by examining marital arrangements among indian households in particular we hypothesize that the marriage of daughters to locationally distant dispersed yet kinship related households is a manifestation of implicit interhousehold contractual arrangements aimed at mitigating income risks and facilitating consumption smoothing in an environment characterized by information costs and spatially covariant risks analysis of longitudinal south indian village data lends support to the hypothesis marriage cum migration contributes significantly to a reduction in the variability of household food consumption farm households afflicted with more variable profits tend to engage in longer distance marriage cum migration the hypothesized and observed marriage cum migration patterns are in dissonance with standard models of marriage or migration that are concerned primarily with search costs and static income gains
