the great recession and the bulimia of us consumers deep causes and possible ways out this paper focuses on the apparent bulimia of us consumers and its role in the recent crisis we seek to show how various characteristics of american society and the us economy are related to this phenomenon we illustrate some structural features of the us economy and public policies that may have created a difference in terms of patterns of consumption and market participation between the usa and continental europe we then present some explanations of us hyperconsumerism put forward by psychologists and sociologists thus relating this phenomenon to the decline in subjective well being and social capital documented in the usa we also discuss how the negative endogenous growth paradigm may help to account for it finally we review the debate on the us policy agenda by underlining some weaknesses in the two politically more realistic options and by outlining a third policy strategy which is possibly preferable for people s long term well being

network based social capital and individual loan repayment performance abstract this study analyses the effects of social capital on the repayment behaviour of borrowers in thailand in the context of agricultural economics an innovative data collection approach is used that originates from the field of sociology a personal network survey is carried out to measure the individual social capital of borrowers social capital variables are defined according to tie strength bonding bridging and social distance linking between the respondent and his her network member bonding social capital has a significant and positive influence on repayment performance however we find no significant evidence for an effect of bridging and linking social capital

learning about a new technology pineapple in ghana this paper investigates the role of social learning in the diffusion of a new agri cultural technology in ghana we use unique data on farmers communication patterns to define each individual s information neighborhood conditional on many potentially confounding variables we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surpris ingly successful in previous periods the relationship of these input adjustments to experience further indicates the presence of social learning in addition applying the same method to input choices for another crop of known technol ogy correctly indicates an absence of social learning effects jel d83 013 033 q16

induced innovation in american agiculture a reconsideration this paper investigates the role of induced innovation in the development of american agriculture from 1880 to 1980 the induced innovation hypothesis most closely associated with the work of hayami and ruttan argues that successful economies develop technologies in accordance with market price signals to loosen constraints on growth imposed by factor scarcities our analysis employing new state and regional level data fails to find support for hayami and ruttan s hypothesis this paper suggests that many of the fundamental generalizations about american agricultural development need to be reconsidered and redirects attention to the role of settlement changing crop patterns and biological investments in explaining changes in factor utilization in american agriculture

preemptive r d rent dissipation and the leverage theory this paper provides a new perspective on the validity of the so called leverage theory in a model of preemptive innovation in systems markets i examine the effect of bundling on r d incentives i find that bundling provides a channel through which monopoly slack in one component market can be shifted to another with the effect of mitigating rent dissipation in the systems market bundling can be profitable if this beneficial effect of reduced rent dissipation outweighs the negative effect of intensified price competition after demonstrating the private optimality of bundling its welfare implications are considered finally the results can be reinterpreted to analyze the relationship between compatibility decisions and r d incentives in mix and match models

compatibility and bundling of complementary goods in a duopoly this paper presents a simple model of compatibility and bundling in industries where consumers assemble several necessary components into a system that is close to their ideal the authors show that for a wide range of parameters firms will choose to produce compatible components but will offer discounts to consumers who purchase all components from the same firm however firms would be better off if they could commit not to provide such discounts furthermore the equilibrium tends to involve socially excessive bundling finally mixed bundling strategies tend to increase the range of parameters over which socially excessive standardization occurs copyright 1992 by blackwell publishing ltd

social capital and institutional trust evidence from bolivia s popular participation decentralisation reforms this article uses bolivia s emblematic process of decentralisation popular participation to explore the elusive relationship between interpersonal and institutional trust as central components of social capital the evidence corroborates the notion that basic social interaction and more complex institutional settings are strongly co related such as the trust that individuals place in their governments and institutions the data also shows that social capital has a direct effect on civic activism and political behaviour at the individual level the notion of social capital is present throughout the analysis as this type of capital allows observing and measuring changes in social structures that affect more complex institutional arrangements

social networks and technology adoption in northern mozambique despite their potentially strong impact on poverty agricultural innovations are often adopted slowly using a unique household dataset on sunflower adoption in mozambique we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks since farmers anticipate that they will share information with others we expect farmers to be more likely to adopt when they know many other adopters dynamic considerations however suggest that farmers who know many adopters might strategically delay adoption to free ride on the information gathered by others we present empirical evidence that shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse u in line with information sharing the network effect is stronger for farmers who report discussing agriculture with others the data contains information which is needed to ameliorate the identification issues that commonly arise in this context in particular social networks are precisely identified and in addition we can control for village heterogeneity and endogenous group formation

is social capital declining in the united states a multiple indicator assessment despite a great deal of interest in a possible decline of social capital in the united states scholars have not reached a consensus on the trend this article improves upon previous research by providing a model of social capital that has explicit links to theories of social capital and that analyzes multiple indicators of social capital over a 20 year period the results do not consistently support putnam s claim of a decline in social capital showing instead some decline in a general measure of social capital a decline in trust in individuals no general decline in trust in institutions and no decline in associations

tax morale and prosocial behaviour evidence from a palestinian survey the first empirical investigation is conducted into the relationship between prosocial behaviour and tax morale in the context of state capacity building as in the palestinian territories we consider public spirit a positive attitude adopted by citizens for the benefit of the community and associational activity individuals engagement in voluntary activities two major expressions of prosocial behaviour and estimate their impact on palestinians tax morale intrinsic motivation to pay taxes the empirical analysis employs a unique palestinian public opinion survey conducted in 2007 in the west bank and the gaza strip by using a bivariate probit model we find that tax morale increases with public spirit but it is lower among palestinians involved in associational activities predicted conditional probabilities indicate that public spirit has more impact when the respondent has low confidence in the institutions and in the rule of law finally more public spirit is required for a self employed person in order to deal with tax compliance than for a worker in the public sector unless the worker in the public sector has lower confidence in the institutions and in the rule of law than the self employed person

an analysis of bundle pricing the case of biotech seeds biotechnology has provided opportunities for strategic management and pricing of patented products this article analyzes the economics and strategy of bundling and bundle pricing of biotech traits in seeds when the bundling of genes traits is decided by biotech firms firms may choose among subadditive pricing component pricing or superadditive pricing strategies we argue that complementarity among component genes contributes to subadditive pricing while substitution among components contributes to superadditive pricing the nature of bundle pricing is explored empirically using u s seed corn data from 2000 to 2007 we document that subadditive bundle pricing of traits is commonly found in the seed corn market however we also present evidence of superadditive pricing and component pricing the presence of different pricing and bundling strategies suggests a rapidly advancing and complex market the preponderance of subadditive pricing suggests that trait bundling offers benefits to farmers exhibiting strong demand for multiple complementary genetic traits jel classifications l4 l13 l65

the dark side of chinese growth declining social capital and well being in times of economic boom summary over the last two decades subjective well being in china declined using data from the world values survey we identify predictors of the trend in life satisfaction in china during 1990 2007 social comparisons and the decline of social capital explain the decrease in well being and they are strictly connected to the increasing orientation of chinese people toward materialistic values the increasing role of social comparisons is also a key factor in the increase of well being inequalities between income classes

the induced innovation hypothesis and u s public agricultural research applicability of the induced innovation hypothesis that a change in relative input prices induces innovation to economize use of the increasingly expensive input hicks 1932 is examined for u s public agricultural research a reduced form test is developed using input prices from the agricultural production sector expenditures from the public research sector aimed at developing new technology to save specific agricultural inputs and variables to control for innovation marginal cost differences and nonhomotheticity unlike recent demand side studies that soundly reject the induced innovation hypothesis for agriculture support for the hypothesis is found for several input pairings through these tests of public agricultural research using state level panel data

valuing product innovation genetically engineered varieties in us corn and soybeans we develop a discrete choice model of differentiated products for us corn and soybean seed demand to study the welfare impact of genetically engineered ge crop varieties using a unique data set spanning the period 1996 2011 we find that the welfare impact of the ge innovation is significant in the last five years of the period analyzed our preferred counterfactual indicates that total surplus due to ge traits was 5 18 billion per year with seed manufacturers appropriating 56 of this surplus the seed industry obtained more surplus from ge corn whereas farmers received more surplus from ge soybeans

bundling as an entry barrier in this paper we look at the case for bundling in an oligopolistic environment we show that bundling is a particularly effective entry deterrent strategy a company that has market power in two goods a and b can by bundling them together make it harder for a rival with only one of these goods to enter the market bundling allows an incumbent to credibly defend both products without having to price low in each the traditional explanation for bundling that economists have given is that it serves as an effective tool of price discrimination by a monopolist although price discrimination provides a reason to bundle the gains are small compared with the gains from the entry deterrent effect i introduction in this paper we look at the case for bundling in an oligopolistic environment we show that bundling is a particularly effective entry deterrent strategy a company that has market power in two goods a and b can by bundling them together make it harder for a rival with only one of these goods to enter the market bundling allows an incumbent to defend both products without having to price low in each while it is still possible to compete by offering a rival bundle a monopolist can significantly lower the potential profits of a one product entrant without having to engage in limit pricing prior to entry we also show that bundling continues to be an effective pricing tool even if entry deterrence fails or if there is already an existing one product rival a company with a monopoly in product a and a duopoly in product b makes higher profits by selling an a b bundle than by selling a and b independently leveraging market power from a into b and accepting some one product competition against the bundle is better than using the monopoly power in good a all by itself since bundling mitigates the impact of competition on the incumbent an entrant can expect the bundling strategy to persist even without any commitment the traditional explanation for bundling that economists have given is that it serves as an effective tool of price discrimination by a monopolist see stigler 1968 adams and yellen

endogenous growth decline in social capital and expansion of market activities abstract we model in an endogenous growth set up the hypotheses that the expansion of market activities weakens social capital formation and that firms can invest in formal mechanisms of control and enforcement to substitute for social capital trust work ethics honesty the model shows that the economy tends to grow faster when it is relatively poorer in social capital and that perpetual growth can be consistent with the progressive erosion of social capital these results may help to reconcile putnam s claim that social capital has declined in the u s with the satisfactory growth performance of the u s over the same period

individual and opportunity factors influencing job creation in new firms we build on multiple theoretical perspectives to investigate the unique and joint effects of individual and opportunity level factors affecting job creation in new firms we tested hypotheses using survey data from individuals who transitioned from unemployment to self employment under the auspices of a german public policy program our findings reveal that an entrepreneur s breadth of knowledge has a negative influence on the firm s job creation whereas the entrepreneur s leadership experience has a positive influence however as the sector specific labor requirements of a business opportunity increase both breadth of knowledge and leadership experience allow founders to operate their firms with fewer employees

supply and demand functions for multiproduct u s cash grain farms biases caused by research and other policies this study presents new estimates of supply and demand elasticities for u s multiproduct cash grain farms and estimates of input and output bias effects caused by public and private crop research extension and farmers schooling the study also shows that the social rate of return to public crop research is large about 62 percent

the location of markets perceived entrepreneurial risk and start up capital of micro rural firms it is argued that when founders of smes perceive the probability of a successful and lucrative venture to be greater they are more likely to provide a greater proportion of the start up capital this paper provides an empirical examination of two concurrent hypotheses firstly that the size of the debt or equity is affected by factors influencing perceived entrepreneurial risk secondly that the location of the market for the firm s output is a major factor reducing perceived entrepreneurial risk and increasing equity of the start up capital a statistical analysis based on the simultaneous tobit model is used results show that significant factors influencing risk perception include the size of the new business and the sector of economic activity as well as entrepreneurial experience and the location of the markets for the firm s output the results highlight implications for the design and implementation of rural development policies and especially for the instruments supporting rural business creation

linking indigenous bonding and bridging social capital o brien d j phillips j l and patsiorkovsky v v 2005 linking indigenous bonding and bridging social capital regional studies 39 1041 1051 reconciling indigenous bonding and bridging social capital remains a difficult issue in economic development and global issues of inequality a failure to address this problem weakens the legitimacy of liberal democratic political institutions mancur olson s logic of collective action 1971 is used as the starting point to identify the structural properties of bridging social capital and the broad parameters within which strategies for using indigenous social capital to create these properties may be found empirical examples from the authors research are used to illustrate alternative ways and the costs and benefits of different strategies for linking indigenous bonding and bridging social capital

inequality and group participation theory and evidence from rural tanzania abstract this paper investigates the determinants of group membership and in particular the effect of income inequality on individual incentives to join economic groups drawing on a simple model we show that an increase in inequality has an ambiguous effect and that the type of access rule open versus restricted access is key in determining what income categories are represented in the group furthermore the shape of the income distribution can be crucial to determine whether increased inequality leads to more or less group participation using survey data from rural tanzania we find that inequality at the village level has a negative impact on the likelihood that the respondents are members of any group this effect is particularly significant for relatively wealthier people both when relative wealth is objectively measured and when it is subjectively defined however when we disaggregate groups by type of access rule we find that inequality decreases participation in open access groups when there are wide disparities at the bottom of the distribution while it increases participation in restricted access groups when the disparities are around the middle and top part of the distribution finally we assess the impact of inequality on various dimensions of group functioning

social capital geography and survival gujarati immigrant entrepreneurs in the u s lodging industry immigrant entrepreneurs often rely on their groups local social capital in their new home market to establish and maintain their businesses in particular immigrant entrepreneurs with few resources of their own receive help from those possessing more resources supporting these arguments using the empirical setting of gujarati immigrant entrepreneurs in the lodging industry we find that the likelihood of survival of an immigrant entrepreneurs hotel increases when surrounded by higher counts of branded hotels representing high resource establishments owned by individuals from their ethnic group but is unaffected by unbranded motels representing low resource establishments owned by members of their ethnic group or by branded hotels owned by individuals from other ethnic groups these results isolate and reinforce the importance of social capital not only for immigrant entrepreneurs but also more generally for any entrepreneurs belonging to ethnic professional religious or social groups

social capital access and entrepreneurship we investigate the effect of social capital access on entrepreneurship social capital helps entrepreneurs to overcome resource constraints this is especially important in small communities where we often see a lack of market oriented institutions such as venture capital firms entrepreneurs gain access to social capital via club memberships combining differences in the number of individual club memberships with differences in the importance of social capital across communities we identify a causal small community mark up effect of individual club memberships on entrepreneurship assuming that unobserved heterogeneity that might influence both the individual s selection into clubs and the occupational choice to be an entrepreneur is independent of community size we find that the effect of club membership on the propensity to be an entrepreneur is 2 6 percentage points larger in small communities than in large communities robustness tests support the validity of our identifying assumption and results

the environmental kuznets curve under a new framework the role of social capital in water pollution we advance a case for including social capital in an environmental kuznets curve analysis using highly disaggregated data of water pollution in louisiana we create a social capital index and employ parametric and spatial panel regression models to explain water pollution dynamics

return migration and occupational choice evidence from albania this paper explores the impact of return migration on the albanian economy by analyzing the occupational choice of return migrants while explicitly differentiating between self employment as either own account work or entrepreneurship we find that the own account workers have characteristics closer to non participants in the labor market i e lower education levels while entrepreneurship is positively related to schooling foreign language proficiency and savings accumulated abroad furthermore compared to having not migrated return migrants are significantly more likely to be entrepreneurs showing the positive impact of migration on job creating activities in albania

social contacts and occupational choice social contacts help workers to find jobs but those jobs need not be in the occupations where workers are most productive hence social contacts can generate mismatch between a worker s occupational choice and his comparative productive advantage thus economies with dense social networks can exhibit apparently low labor force quality and as a result low returns to firms investment and depressed aggregate productivity we employ us and european data for the 1990 s to test the key prediction that social contacts distort workers occupational choices in a direction that reduces their apparent productivity we find that the use of social contacts helps find jobs one to two months sooner but leads to individual wage discounts of 5 to 7 and produces negative externalities on aggregate productivity

geographic aggregation and induced innovation in american agriculture the induced innovation hypothesis is tested for the usa and western regions using cointegration procedures an error correction model separates short run and long run effects of relative price changes a significant difference in the elasticities of factor substitution along the isoquant and the innovation possibility curve implies induced innovation the estimated results support the hypothesis for washington the pacific northwest and the western region but not for the nation corroborative tests of weak exogeneity fail to support the hypothesis in any of the geographic units changes in output level and research investment do not significantly bias agricultural technology in the usa

job information networks neighborhood effects and inequality this paper explores the theoretical and empirical literature to examine the use by different social groups of informal sources of information provided by friends relatives and acquaintances during job search and its consequences for the job market it also addresses the role of network structure and size the resource endowments of contacts and nature of the links between contacts to explain differences in the effects of job information networks in doing so the paper also turns to the sociology literature on job information networks and provides an economic perspective on such sociological concepts as strong versus weak ties inbreeding distance from structural holes etc the paper distinguishes between models of exogenous job information networks that is where individuals obtain job related information through a given social structure and endogenous job information networks which are social networks that result from individuals uncoordinated actions the paper pays special attention to such issues as physical and social proximity and sharing of information and discusses them in the context of the recent social interactions and neighborhood effects literature finally the paper outlines a model that integrates job information networks where interactions occur in business cycle frequencies with the dynamics of human capital formation which include the joint effects of parental community and neighborhood human capital and are set in life cycle frequencies for the purpose of organizing suggestions for future research and examining earned income inequality

agricultural productivity revisited this paper describes production accounts for agriculture output is defined as gross production leaving the farm as opposed to real value added inputs are not limited to capital and labor but include intermediate inputs as well we derive index numbers of gross output capital labor and intermediate inputs these data are used to construct indexes of total factor productivity we then compare the contributions of input growth and productivity growth to economic growth the important role of productivity growth in agriculture becomes immediately apparent

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

knowledge sharing and the dynamics of social capital abstract mutual aid often entails the sharing of knowledge we investigate how in turn knowledge sharing affects the long run dynamics of mutual aid in our economy agents with specific knowledge are held up by their principals inside communities agents aid each other by sharing their specific knowledge this process generates a new type of knowledge which exacerbates the specificity of the existing types and induces more agents to engage in mutual aid however since the knowledge generated is shared it progressively renders agents inside communities more flexible and thus less dependent on mutual aid we characterize conditions under which in the long run mutual aid spreads or is abandoned

determinants of microenterprise performance in nepal although the literature on entrepreneurship studies has contributed significantly in improving our insights regarding the factors determining the enterprise performance in a broader sense there has been a little research concerning the factors determining the microenterprise performance using primary data enumerated from 501 micro entrepreneurs randomly sampled across different strata gender caste ethnicity enterprise category and ecological belts in nepal in 2013 for the years 2068 bs april 2011 march 2012 and 2069 bs april 2012 march 2013 and executing the multiple linear regression models the study primarily focused on identifying the factors determining the microenterprise performance the study revealed that the entrepreneur related factors particularly gender managerial skills need for achievement need for autonomy creative tendency internal locus of control and managerial foresight enterprise related factors particularly enterprise age enterprise size and initial financial constraint and environment related factor particularly social network were the key factors determining the performance of microenterprises in nepal

statistical discrimination with peer effects can integration eliminate negative stereotypes we introduce peer effects in the costs of human capital acquisition into a model of statistical dis crimination in labour markets this creates a link between the level of segregation in social networks and racial disparities in job assignment and wages we show that this relationship is characterized by disconti nuities there is a threshold level of segregation below which negative stereotypes become unsustainable and steady state skill levels can change dramatically this change can work in either direction skill levels may either rise or fall in both groups vvtiich of these outcomes arises depends on the population share of the disadvantaged group and on the distribution of the costs of human capital investments we also examine the effects of affirmative action policies in the presence of peer effects and provide conditions under which such policies eliminate negative stereotypes

optimal bundling and pricing under a monopoly contrasting complements and substitutes from independently valued products we develop an analytical model of contingent valuations and address two questions of import to a monopolist i should a given pair of complements or substitutes be sold separately pure components together pure bundling or both mixed bundling and at what prices ii how do optimal bundling and pricing strategies for complements and substitutes differ from those for independently valued products we find that the combination of marginal cost levels and the degree of complementarity or substitutability determines which of the three bundling strategies is optimal complements and substitutes should typically be priced higher than independently valued products

governments reciprocal exchange and trust among business associates both pearce and molm have conducted research in interpersonal trust here we apply their work to international business by deriving hypotheses from their work some compatible some conflicting we test them with data from managers in china the united states hong kong and thailand using measures from the world bank world competitiveness report and transparency international and managerial interviews we find support for pearce s arguments on the effects of governmental facilitation on managers trust in their business partners and for extensions of molm s work on reciprocal exchange to international field settings for the conflicting hypotheses results support pearce s arguments that the structural assurances of facilitative governments lead to higher levels of trust in business associates

social capital and growth we define and characterize social capital in a simple growth model we capture social capital in a model where individuals in a community maximize their lifetime gains to trade each trade between two members of a community has the structure of the prisoners dilemma trades are repeated indefinitely but not necessarily each period social capital is defined as the social structure which facilitates cooperative trade as an equilibrium the trading model is incorporated into a growth model to explore the connections between growth labor mobility and social capital the key assumption is that technological innovation which drives growth involves a reallocation of labor that affects social capital modifying the responsiveness of labor to a technological shock has implications for both labor efficiency and social capital

gaussian demand and commodity bundling in an important and widely cited essay adams and yellen 1976 examine the use of package selling as a price discrimination device they consider a monopolist producing two goods with constant unit costs and facing buyers with diverse tastes the marginal utility of a second unit of either good is assumed to be zero for all buyers the two goods are independent in demand for all buyers so that any buyer s reservation price for the first unit of either good is independent of the market price of the other thus the maximum amount any buyer would pay for a bundle consisting of one unit of each good is the sum of the two reservation prices and buyers are completely described by the values of those two prices 2 resale markets are assumed away in order to obtain comparative results for alternative pricing strategies the distribution of reservation prices in the adams yellen framework is assumed to be bivariate normal implications of gaussian demand are explored pure bundling is shown to operate by reducing buyer diversity thus facilitating the capture of consumers surplus it generally makes buyers worse off than unbundled sales it is more profitable if average reservation prices are high enough mixed bundling combines advantages of both pure bundling and unbundled sales and it is generally strictly more profitable than either bundling which treats goods symmetrically seems most attractive under symmetric reservation price distributions i am indebted to severin borenstein for superb research assistance to the ford motor company for research support through a grant to m i t and to the harvard economics department for housing me as a visiting scholar while most of this research was performed of course only i can be held responsible for this essay s shortcomings 1 the first clear recognition of this possibility seems to have been by stigler 1968 but also see burstein 1960 2 paroush and peles 1981 relax the assumption that consumers purchase at most one unit of each good but they consider only two types of buyers both with linear demand functions they retain the assumption that demands are independent for all buyers telser 1979 and phillips 1981 use different frameworks to analyze bundling policies spence 1980 explores the relation between bundling across commodities as here and bundling multiple units of the same

tying foreclosure and exclusion in recent years the leverage theory of tied good sales has faced heavy and influential criticism in an important sense though the models used by its critics are actually incapable of addressing the leverage theory s central concerns here the author reconsiders the leverage hypothesis and argues that tying can indeed serve as a mechanism for leveraging market power the mechanism through which this leverage occurs its profitability and its welfare implications are discussed in detail copyright 1990 by american economic association

sustainable urban livelihoods and marketplace social capital crisis and strategy in petty trade urban growth has been accompanied by the development of bimodal labour markets and increasing inequalities in both north and south in southern cities many of the poor have turned to the informal sector in particular to street trade this has resulted in a multiplicity of urban conflicts and has led to pressure on urban managers to undertake formalisation for which an increasingly developmental approach has been advocated nevertheless for traders the formalisation of street trade has very uneven outcomes the starting point for this article is the premise that not enough is known about the social fabric upon which trading careers depend adopting sustainable livelihoods as a conceptual framework and drawing on social capital theory four questions are addressed how do trading careers survive over time are there differences in the survival strategies for which social capital is employed among traders operating in different political cultural and socioeconomic contexts in the new processes of urba

trust in large organizations several authors suggest that trust is an important determinant of cooperation between strangers in a society and therefore of performance of social institutions we argue that trust should be particularly important for the performance of large organizations in a cross section of countries evidence on government performance participation in civic and professional societies importance of large firms and the performance of social institutions more generally supports this hypothesis moreover trust is lower in countries with dominant hierarchical religions which may have deterred networks of cooperation trust hold up remarkably well on a cross section of countries this abstract was borrowed from another version of this item

the welfare effects of bundling in multichannel television markets we measure how the bundling of television channels affects short run welfare we estimate an industry model of viewership demand pricing bundling and input market bargaining using data on ratings purchases prices bundles and input costs we conduct simulations of a la carte policies that require distributors to offer individual channels for sale to consumers we estimate that negotiated input costs rise by 103 0 percent under a la carte these higher input costs offset consumer benefits from purchasing individual channels mean consumer and total surplus change by an estimated 5 4 to 0 2 percent and 1 7 to 6 0 percent respectively jel d12 l11 l51 l82 m31

bundling and licensing of genes in agricultural biotechnology we examine the strategic incentive for gene holders to vertically integrate with seed companies and chemical input companies with homogeneous conventional seeds we find that a pure bundling strategy produce the genetically modified seed only is dominant when the gene holder and breeder are respectively the monopolistic producers of genetically modified and conventional seeds they may commit to mixed bundling supply both genetically modified and conventional seed to deter potential entry to the conventional seed market a vertical merger may solve the credibility issue of the mixed bundling commitment through third party licensing agreements in the conventional seed market copyright 2009 oxford university press

self employment and the earnings of immigrants we examine the question of the economic returns to immigrants engaged in self employment based on samples of four entrepreneurial immigrants plus control samples of blacks and whites from the 1980 u s public use microdata sample we find large differences in the net effect of self employment depending on the use of a linear absolute dollar values or loglinear relative returns form we examine various explanations for the discrepancy and identify the role of outliers as significant the loglinear form fits the data better but at the cost of obliterating substantively important information namely the preponderance of the self employed among positive outliers effects of excluding the latter from the linear form and the theoretical and policy implications of alternative specifications of the earnings equation are examined excerpt

to bundle or not to bundle commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation or if the distribution of valuations is very peaked around the mean

capital services in u s agriculture concepts comparisons and the treatment of interest rates this paper begins with a review of the methods and assumptions used to measure capital service flows two data series on capital inputs in u s agriculture are briefly described and compared we show that measures of capital services are sensitive to the treatment of interest rates notably the use of fixed versus variable market rates significantly affects measures of the quantity and productivity of agricultural capital in the united states we conclude that when calculating capital usage in u s agriculture the use of a fixed interest rate generates more plausible estimates than the use of an annual market rate

social network structure segregation and equality in a labor market with referral hiring abstract we examine the effects of social network structure on inequality in a model of referral hiring that focuses on groups rather than individuals more random social networks yield higher employment rates than less random ones if the population is integrated or job vacancy information flows are random however less random social networks allow for better containment of job information inside a group in a segregated population with non random job information flows resulting in higher employment rates we report on the robustness of these findings with respect to the size of minority and majority groups and the amount of social segregation

a strategic motivation for commodity bundling the analytical literature on commodity bundling explains the practice of selling two or more differentiated products in a single package as a surrogate for direct price discrimination in contrast this paper shows that imperfect competition creates a strategic incentive to bundle the profitability of bundling whether it adversely affects rival producers and whether it yields an overall efficiency gain depends inter alia on the nature of product market competition the role of complementarity in explaining why firms bundle is also explored copyright 1990 by blackwell publishing ltd

the structure of u s agricultural technology 1910 78 this paper utilizes 1910 78 time series data and a single product aggregate translog profit function to measure the structure of u s agricultural technology duality relations are used to devise a multifactor measure of biased technical change a measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares the empirical analysis finds that different nonhomothetic technologies characterized the prewar and postwar periods differing technical change biases are consistent with relative price trends during the two periods showing that the long run structure of u s agricultural technology has been consistent with the hayami ruttan induced innovation theory

networks in labor markets wage and employment dynamics and inequality we present a model of labor markets that accounts for the social network through which agents hear about jobs we show that both wages and employment are positively associated a strong form of correlation across time and agents we also analyze the decisions of agents regarding staying in the labor market or dropping out if there are costs to staying in the labor market then networks of agents that start with a worse wage status will have higher drop out rates and there will be a persistent differences in wages between groups according to the starting states of their networks

social capital and loan repayment performance in northern vietnam this study analyses the effects of social capital on the loan repayment behavior of borrowers in vietnam in the context of agricultural economics an innovative data collection approach is used that originates from the field of sociology a personal network survey is carried out to measure the individual social capital of borrowers social capital variables are defined according to tie strength bonding bridging and social distance linking between the respondent and his her network member social capital has a significant and positive influence on the rescheduling of loans however we find no significant evidence for an effect of social capital on late payment of principal or interest

a note on the theory and measurement of trust in explaining differences in economic growth this paper takes issue with the trend to attribute differences in economic growth rates to differences in interpersonal trust i discuss the world values survey wvs measure that is used to operationalise trust at the macro level i hypothesise that there is a mismatch between the theoretical argument and the empirical operationalisation of trust instead of measuring trust the wvs measure may instead proxy the well functioning of institutions i provide circumstantial evidence for this thesis by a principal components analysis of trust and institutions and a robustness test of zak and knack s 2001 trust and growth economic journal vol 111 295 321 seminal study on trust and economic growth

testing the induced innovation hypothesis an error correction model of south african agriculture abstract this paper applies cointegration techniques to a model of induced innovation based on the two stage constant elasticity of substitution ces production function this approach results in direct tests of the inducement hypothesis which are applied to data for south african commercial agriculture for the period 1947 1991 south african data is used because the policy changes have been substantial enough that the factor and price ratios have turning points rather than being monotonic the time series properties of the variables are checked cointegration is established and an error correction model ecm constructed allowing factor substitution to be separated from technological change finally the ecm formulation is subjected to causality tests which show that both the factor price ratios and r d and extension expenditures are granger prior to the factor saving biases of technological change thus each stage of the analysis corroborates the inducement hypothesis however straightforward price inducement is only part of the explanation of changes in factor ratios policy induced innovation in response to tax concessions and subsidised credit is also present

social capital and the dynamics of trust in government it is well understood that trust in government responds to the performance of the president congress and the economy despite improved government performance however trust has never returned to the levels witnessed in the 1950s and 1960s social capital may be the force that has kept trust low if so we need to assess the relative contributions of both government performance and social capital at the macro level using macrolevel data the analysis here is designed to capture the variation over time in both social capital and government performance and let them compete to explain the macro variation in trust the empirical results demonstrate that both government performance and social capital matter but that social capital appears to be the force which accounts for the decline in trust over the last 40 years

equilibrium product bundling this article offers an equilibrium theory of product bundling by rival firms in several models where a primary good is produced in a duopoly market and one or more other goods is produced under perfectly competitive conditions bundling is shown to emerge as an equilibrium strategy of one or both of the duopolists for its role as a product differentiation device when the rival firms can commit to bundling sales their profits are higher but social welfare is reduced copyright 1997 by university of chicago press

the effects of social networks on employment and inequality we develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts we show that employment is positively correlated across time and agents moreover unemployment exhibits duration dependence the probability of obtaining a job decreases in the length of time that an agent has been unemployed finally we examine inequality between two groups if staying in the labor market is costly and one group starts with a worse employment status then that group s drop out rate will be higher and their employment prospects will be persistently below that of the other group

induced bias of technical change in agriculture the united states and japan 1880 1980 because of extreme differences in factor endowments and price ratios among factors between the united states and japan both countries have experienced sharply different patterns of factor use and productivity growth in agriculture for the past 100 years of modern economic growth in this study the method of testing the hicksian hypothesis of induced innovation was developed using the two level ces production function the model was applied to the historical data of u s and japanese agricultural development for 1880 1980 the results were consistent with the hypothesis that different patterns of technical change in the two countries were induced by differences in the levels and the movements in relative factor prices

immigrant self employment the family as social capital and the value of human capital we examine how self employment among asian and hispanic immigrants is affected by family composition and human capital class resources because of collective interests and strong personal ties the family facilitates the pooling of labor power and financial resources enterprising immigrants draw on these resources when establishing and operating small businesses our findings also show the importance of human capital class resources in accounting for immigrant self employment although foreign earned human capital is usually not highly valued in the host labor market immigrants successfully use this human capital to achieve business ownership interethnic variation in personal human capital and family composition accounts for a substantial portion of the observed interethnic variation in self employment the data are drawn from the 1980 five percent pums for greater new york city and los angeles excerpt

the approach of institutional economics this paper assesses the old institutional economics it emphasizes the importance of key old institutionalist themes concerning the necessity of habits and rules and the role of institutions a problem in the alternative theoretical program of the new institutionalism is the untenability of its assumption of an original institution free market or state of nature even optimizing behavior requires the prior existence of habits and rules although it still lacks a complete and systematic theory the evolutionary approach of the old institutionalists tackles the problem of the interactive relationship of actor to structure without analytical reduction to one or the other

an investigation into the overseas expansion of small asian owned u k firms this paper contributes to the growing body of knowledge in international entrepreneurship by reporting on a qualitative empirical investigation into the overseas expansion processes of small asian originating from the indian sub continent owned firms operating in the u k clothing industry the key decision makers within these firms frequently identified themselves as an active and important influence upon the actual activities of their firms as international operators for some firms though a more passive approach to internationalisation could be identified whereby the receipt of unsolicited orders had an effect on some firms timing of overseas market entry the balance between the nature of opportunities that frequently derived from cultural networks and the constraints of a limited resource base with which to exploit those opportunities also had a major impact on the direction and pace of certain firms overseas expansion the findings suggest a general tendency to adopt an incremental approach to internationalisation within this mature trade sector the cultural and business experience of managers however was found to have an effect on the pace and direction of the overseas expansion recommendations on the likely efficacy and effectiveness of public private sector interaction within the area of international entrepreneurship involving entrepreneurs from asian backgrounds are offered

land use compatibility change and policy at the rural urban fringe insights from social capital cerning the level and quality of services to be provided in the community pendall and martin lacayo nonfarm development also impacts agriculture with the loss of farmland and the difficulties of farming amidst a large nonfarm population receiving considerable attention by citizens policy makers and academics american farmland trust successfully managing changes at the ruralurban interface requires improved data technical expertise and political leadership at all levels of government success also depends we believe on the existence of social capital in this article we focus on the importance of social capital in managing change at the rural urban interface our starting assumption is that individuals or communities with access

multiproduct monopoly commodity bundling and correlation of values through what selling strategy can a multiproduct monopolist maximize his profits when his knowledge about individual consumers preferences is limited one possibility extensively studied in the context of a single good monopoly is to use quantity dependent pricing as a means of discriminating among customers with differing tastes see for example oi 1971 and maskin and riley 1984 an alternative technique for price discrimination first suggested by stigler 1968 and analyzed further by adams and yellen 1976 is for the monopolist to package two or more products in bundles rather than selling them separately through a series of examples adams and yellen illustrate that bundling can serve as a useful price discrimination device even when all consumers willingnesses to pay for each of the goods individually are unaffected by whether they are also consuming the other product a typical example is illustrated in figure i adapted from figure iv in adams and yellen where there are two goods three consumers ab c who consume at most one unit of each good with reservation values for each good that are independent of whether the other good is consumed and zero costs of production there a bundle offered at a price of 100 fully extracts all potential surplus which would be impossible pricing the goods independently unfortunately though these authors do not provide any general characterization of the circumstances in which bundling is actually a multiproduct monopolist s optimal strategy their examples however such as figure i create the impression that the profitable use of bundling

city structure job search and labour discrimination theory and policy implications we consider a search matching model in which black workers are discriminated against and the job arrival rates of all workers depend on social networks as well as distance to jobs location choices are driven by the racial preferences of households both blacks and whites consciously choosing to trade off proximity to neighbors of similar racial backgrounds for proximity to jobs because of coordination failures in the location choices multiple urban equilibria emerge there is a spatial mismatch equilibrium in which blacks reside far away from jobs and experience high unemployment rates and a spatial match equilibrium in which blacks are closer to jobs and experience lower unemployment rates under some reasonable condition we demonstrate that all workers are better off in the spatial match equilibrium we then consider two policies affirmative action and employment subsidies to the firms which hire black workers we show that the optimal policy requires imposing larger quotas or subsidies in cities in which black workers reside far away from jobs than in cities in which they live closer to jobs

induced innovation in u s agriculture time series direct econometric and nonparametric tests the hypothesis of induced innovation is tested for u s agriculture using a high quality state level panel data set and three disparate testing techniques time series direct econometric and nonparametric we find little support for the hypothesis that conclusion is robust across testing techniques however as with all empirical tests of this hypothesis conducted to date ours focus only on the demand side of the hypothesis the hypothesis could have been rejected simply because the marginal cost of developing and implementing input saving technologies for the relatively expensive inputs is greater than for the relatively cheap inputs copyright 2009 oxford university press

networks in the modern economy mexican migrants in the u s labor market this paper attempts to identify job networks among mexican migrants in the u s labor market the empirical analysis uses data on migration patterns and labor market outcomes based on a sample of individuals belonging to multiple origin communities in mexico over a long period of time each community s network is measured by the proportion of the sampled individuals who are located at the destination the united states in any year we verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger by including individual fixed effects in the employment and occupation regressions and by using rainfall in the origin community as an instrument for the size of the network at the destination

an analysis of the pricing of traits in the u s corn seed market we investigate the pricing of traits in the u s corn seed market under imperfect competition in a multiproduct context we examine how substitution complementarity relationships among products can affect pricing this is used to motivate generalizations of the herfindahl hirschman index capturing cross market effects of imperfect competition on pricing the model is applied to pricing of u s conventional and biotech seeds from 2000 to 2007 we reject the standard component pricing in biotech traits in favor of subadditive bundle pricing the econometric estimates show how changes in market structure as measured by both own and cross herfindahl indexes affect u s corn seed prices

an analysis of the source and nature of technical change the case of u s agriculture this paper proposes a methodology to investigate the process of technical change with a focus on the dynamic effects of r d investments on productivity and on the induced innovation hypothesis for both inputs and outputs the approach builds on a nonparametric representation of the underlying technology an application to u s agriculture is presented by distinguishing between private and public r d investments the analysis provides useful insights into the source and the dynamic nature of technical progress

some contacts are more equal than others informal networks job tenure and wages the explanation typically given for longer tenure among workers who use informal contacts to find jobs is that relatives and friends reduce uncertainty about the quality of the match between worker and employer an alternative explanation is that workers rely on informal information sources as a last resort such workers remain at their current jobs mainly because they have few alternative choices rather than because of better match quality this article shows that the two different explanations are simultaneously valid for different types of contacts and can account for differences in the wage effects of job contacts

markets hierarchies and networks an agent based organizational ecology markets hierarchies and networks are widely understood to be the three primary forms of social organization in this article we study the choice between these forms in a general agent based model abm of cooperation the organizational ecology is the product an emergent property of the set of choices made by agents contingent on their individual attributes and beliefs about the population of agents this is one of the first attempts to theorize explicitly the choice between different organizational forms especially networks and hierarchies and certainly the first to do so in an abm the insights of the model are applied to current research on transnational networks social capital and the sources of hierarchy and especially autocracy

the evolution of social norms in common property resource use the problem of extracting commonly owned renewable resources is examined within an evolutionary game theoretic framework it is shown that cooperative behavior guided by norms of restraint and punishment may be stable in a well defined sense against invasion by narrowly self interested behavior the resource stock dynamics are integrated with the evolutionary game dynamics effects of changes in prices technology and social cohesion on extraction behavior and the long run stock are analyzed when threshold values of the parameters are crossed social norms can break down leading generally to the lowering of the long run stock and possibly to its extinction copyright 1996 by american economic association

an institution based view of executive compensation a multilevel meta analytic test we offer a multilevel meta analytic study of the firm performance executive compensation relationship comprising prior tests derived from 332 primary studies nested in 29 countries although our work modestly supports the optimal contracting theory based expectation that compensation is positively associated with performance it also reveals considerable cross country variability in this relationship we trace this variance to differences in the level of development of the formal and informal institutions protecting investors against managerial overcompensation and underperformance in terms of intentionally devised and enforced formal institutions we find significant positive moderating effects on the focal relationship of the rule of law and strength of investor protection variables for self enforcing informal institutions we find similar effects for concentrated ownership and compensation related entries in codes of good corporate governance we also find that formal and informal institutions function in a complementary manner in shaping the performance sensitivity of executive compensation the focal relationship becomes stronger when concentrated owners have access to well functioning courts and when informal norms of good governance are supported by shareholder protection laws our study thus suggests that optimal contracting theory must be supplemented with an institution based view to account for the conditioning effects of institutions on national contracting environments

matchmaker matchmaker the effect of old boy networks on job match quality earnings and tenure firms often view job applicant referrals from current employees as more informative than direct applications or referrals through formal labor market intermediaries such as placement firms we argue that old boy networks reduce employers uncertainty about worker productivity using jovanovic s job matching model we show that workers hired through the old boy network should 1 earn higher initial salaries 2 experience lower subsequent wage growth on the job and 3 stay on the job longer than otherwise comparable workers hired from outside the network we find considerable support for this theory using data from the 1972 survey of natural and social scientists and engineers
