zombie lending and depressed restructuring in japan this paper explores the role that misdirected bank lending played in prolonging the japanese macroeconomic stagnation that began in the early 1990s the investigation focuses on the wide spread practice of japanese banks of continuing to lend to otherwise insolvent firms we docu ment the prevalence of this forbearance lending and show its distorting effects on healthy firms that were competing with the impaired firms the paper by hoshi 2000 was the first to call attention to this phenomenon and its ramifi

collective reputation and quality firms who sell regional or specialty products often share a collective reputation based on aggregate quality collective reputation can be approached as a dynamic common property resource problem we show that for an experience good without firm traceability individual firms have the incentive to choose quality levels that are sub optimal for the group these results support minimum quality standards trigger strategies are analyzed as an alternative solution to this problem finally the implications of these results are discussed as they relate to the case study of washington apples specialty regional authentic and local food products have become a more important part of consumer purchases in recent years firms have responded by marketing food products that come from specific geographic areas this trend in consumers preferences has led the european union to introduce protected designations of origin labels and protected geographical identification labels which provide protection of food names on a geographical or traditional basis ranging from parmesan cheese to such lesser known items such as galician veal in the united states there are popular state products that carry labels such as washington apples idaho potatoes

do private standards create exclusive supply chains new evidence from the peruvian asparagus export sector abstract developing countries are increasingly exporting fresh horticultural products to high income countries these exports increasingly have to comply with stringent public and private standards as well as other quality and safety issues there is an ongoing debate on the effect of private standards on the inclusion of small scale farmers in export supply chains with this paper we contribute to this debate by providing new evidence from the peruvian asparagus export sector and by addressing several important methodological shortcomings and gaps in the existing literature we describe export dynamics using a unique firm level dataset on 567 asparagus export firms from 1993 to 2011 and the evolution of certification to private standards using own survey data from a stratified random sample of 87 export firms we use an unbalanced panel of the surveyed companies on 19 years and several methods including fixed effects and gmm estimators to estimate the causal impact of certification to private standards on companies sourcing strategy we find that certification leads to vertical integration and significantly reduces the share of produce that is sourced from external producers with a larger effect for small scale producers when distinguishing between production and processing standards and between low level and high level standards we find that especially high level production standards have a negative impact on sourcing from small scale producers

the political economy of the maoist conflict in india an empirical analysis we study the maoist naxalite conflict in india by constructing a comprehensive district level database combining conflict data from four different terrorism databases to socioeconomic and geography data from myriad sources using data on 360 districts for three time periods we find that land inequality and lower incomes are important factors behind the conflict exploiting the micro structure of the data we show that growth of incomes of scheduled tribes significantly decreases the intensity of the conflict finally we show that historical property rights institutions from colonial times that go back centuries affect present day conflict outcomes

method in the madness a political economy analysis of the ethnic conflicts in less developed countries this paper is an attempt from a political economist s point of view to look for some clear patterns in the horrendous complexities of the ethnic and sectarian conflicts that are raging in less developed countries we emphasize the importance of some institutional failures such as the decline of mediating institutions or of preexisting structures of credible commitment rather than mere cultural and historical animosities behind the collapse of interethnic understandings and compromises the rise in ethnic conflicts is not always associated with economic deterioration sometimes quite the contrary the effects of market expansion are also ambiguous in our discussion of policy lessons we have tried to look for various ways both political and economic of constructing institutionalized incentives for conciliatory actions

understanding variations in local conflict evidence and implications from indonesia recent studies of large scale headline conflicts have excluded consideration of local conflict in large part due to the absence of representative data at low levels of geographic specification this paper is a first attempt to correct for that by assessing the incidence impacts and patterns of local conflict in indonesia we employ a combination of qualitative fieldwork with an exploratory statistical analysis of the 2003 village potential statistics collected by the bureau of statistics potensi desa podes which maps conflict across all of indonesia s villages neighborhoods violent conflict can be observed throughout the archipelago the qualitative analysis shows that local conflicts vary in form and impacts across districts and that local factors are key the quantitative analysis which excludes high conflict areas of indonesia confirms the importance of economic factors with positive correlations between violent conflict and poverty inequality and variables measuring economic development clustering of ethnic groups and ill defined property rights were also positively associated with violence

the political economy of public goods some evidence from india we are interested in how public goods get allocated by a centralized state we use data on public goods and social structure from parliamentary constituencies in rural india to understand the allocation of these goods over the 1970s and 1980s national policies and political agendas during this period emphasized universal access to basic amenities and financed a rapid expansion in rural infrastructure we find evidence of considerable equalization in many of these facilities reflecting perhaps the importance of these commitments among the historically disadvantaged social groups those that mobilized themselves politically gained relative to the others measures of social heterogeneity that have been emphasized in the recent empirical literature on public goods are relevant but not overwhelming in their importance

demand for beef and chicken products separability and structural change several studies have indicated that the recent shift from beef to poultry in consumption is not entirely caused by changes in rela tive prices or income braschler chavas dahlgran hudson and vertin moschini and meilke frank thurman most studies of structural change have focused on red meat consumption only thurman has looked closely at the poultry market and no one has considered poultry products yet the mix of chicken products marketed changed dramat ically during the last twenty years and should have influenced aggregate meat demand the share of broiler slaughter marketed as whole birds declined from 74 in 1965 to 28 in 1985 while cut up parts and processed chick en products increased from 26 to 72 whole birds are inferior goods and cut up parts and processed chicken are normal goods haidacher et al the shift in chicken prod uct mix away from whole birds should have increased the preference for total chicken in this article two related questions are ad dressed first do consumers allocate expendi tures among meats by animal origin or by product type second does disaggregation of meat into products in a meat demand model give insight into the causes of structural

can mandated political representation increase policy influence for disadvantaged minorities theory and evidence from india accountable governments often fail to reflect the interests of disadvantaged minorities this paper exploits the institutional features of political reservation as practiced in indian states to examine the role of mandated political representation in providing disadvantaged groups influence over policy making ifind that political reservation has increased transfers to groups which benefit from the mandate this finding also suggests that complete policy commitment may be absent in democracies as is found in this case jel d72 d78 hl 1 h50

history institutions and economic performance the legacy of colonial land tenure systems in india we analyze the colonial land revenue institutions set up by the british in india and show that differences in historical property rights institutions lead to sustained differences in economic outcomes areas in which proprietary rights in land were historically given to landlords have significantly lower agricultural investments and productivity in the post independence period than areas in which these rights were given to the cultivators these areas also have significantly lower investments in health and education these differences are not driven by omitted variables or endogeneity problems they probably arise because differences in historical institutions lead to very different policy choices

total factor productivity growth in local enterprise partnership regions in britain 1997 2008 harris r and moffat j total factor productivity growth in local enterprise partnership regions in britain 1997 2008 regional studies this paper decomposes aggregate total factor productivity tfp growth in britain for 1997 2008 to show the contribution of different local enterprise partnerships leps as well as manufacturing and services and uk and foreign owned plants within leps these contributions are further decomposed to show the role of productivity growth in continuing plants vis a vis reallocations in output shares the results show that the largest leps in population terms with higher levels of job density a greater reliance on manufacturing more skilled and better qualified workers and a lower turnover of businesses achieved the highest tfp growth this is mostly the result of reallocations of output shares towards high productivity plants

demand for collective food safety standards in 2007 leading members of the u s fresh tomato industry responded to pressure from the u s food and drug administration regarding the industry s long history of poor food safety outcomes and adopted a set of standards for production practices related to food safety at all levels of the fresh tomato supply chain adherence to these standards was required under a federal marketing order that applied to essentially all tomatoes grown in florida the california tomato farmers cooperative whose members produced the vast majority of fresh tomatoes grown in california also required that its members adopt these standards the collective food safety standards for fresh tomatoes closely resemble the requirements of the u s food safety modernization act fsma produce safety rule so the collective adoption of these standards provides an excellent case study to illustrate the possible effects of fsma implementation on demand i assess the hypothesis that demand for tomatoes from florida and california increased following the adoption of standards for food safety practices by growers in those states relative to demand for tomatoes from other regions my analysis demonstrates essentially no evidence that demand for fresh tomatoes responded positively to the implementation of collective food safety practices

the inverse almost ideal demand system abstract a new demand system related to the almost ideal demand system aids of deaton and muellbauer is developed and illustrated this inverse aids iaids retains all of the desirable theoretical properties of the aids model with the exception of consistent aggregation an empirical issue is whether a linear approximation will work as well for the iaids as it has for the aids model since quantities are not as highly correlated as prices an application to u s meat demand demonstrates that the linear approximation of the iaids is excellent which enhanced the ease and range of application

conflict and distribution abstract we develop a behavioral model that links the level and pattern of social conflict to the societywide distribution of individual characteristics the model can be applied to groups that differ in characteristics such as wealth ethnicity religion and political ideology we settle questions of existence and uniqueness of conflict equilibrium conflict is seen to be closely connected with the bimodality of the underlying distribution of characteristics however in general the conflict distribution relationship is nonlinear and surprisingly complex our results on conflict patterns also throw light on the phenomena of extremism and moderation journal of economic literature classification numbers d63 d72 d74

workers warriors and criminals social conflict in general equilibrium we incorporate appropriation activities social conflict into canonical models of trade and study how economic shocks and policies affect the intensity of conflict we show that not all shocks that could make society richer reduce conflict positive shocks to labor intensive industries diminish conflict while positive shocks to capital intensive industries increase it the key requirement is that conflict activities be more labor intensive than the economy as this determines how shocks affect the returns and costs of conflict our theory is consistent with several observed patterns of conflict and implies that empirical work should take into account the relative factor intensities of the productive and conflict sectors in each country incorporating appropriation into a canonic general equilibrium model affects what policies may be deemed desirable in order to reduce conflict and generate pareto improvements policy must be distortionary while reforms that appear efficiency enhancing under the unrealistic assumption of perfect property rights may backfire this offers one explanation for why reforms based on traditional models without appropriation may be delayed and become unpopular when implemented and why societies may sympathize with seemingly inefficient redistribution

factor endowments inequality and paths of development among new world economies whereas traditional explanations of differences in long run paths of development across the americas generally point to the significance of differences in national heritage or religion we highlight the relevance of stark contrasts in the degree of inequality in wealth human capital and political power in accounting for how fundamental economic institutions evolved over time we argue moreover that the roots of these disparities in the extent of inequality lay in differences in the initial factor endowments dating back to the era of european colonization we document through comparative studies of suffrage public land and schooling policies systematic patterns by which societies in the americas that began with more extreme inequality or heterogeneity in the population were more likely to develop institutional structures that greatly advantaged members of elite classes and disadvantaging the bulk of the population by providing them with more political influence and access to economic opportunities the clear implication is that institutions should not be presumed to be exogenous economists need to learn more about where they come from to understand their relation to economic development our findings not only contribute to our knowledge of why extreme differences in the extent of inequality across new world economies have persisted for centuries but also to the study of processes of long run economic growth past and present

plant closure in britain since the great recession one of the suggested explanations for the uk productivity puzzle is that since the onset of the great recession low productivity plants that would normally have closed have continued operating this paper therefore investigates whether there has been a change in the relationship between productivity and closure since the recession we find that for a number of sectors the negative association between tfp and closure that existed prior to the recession has been offset or even reversed since the recession

investor protection and corporate governance recent research has documented large differences among countries in ownership concentration in publicly traded firms in the breadth and depth of capital markets in dividend policies and in the access of firms to external finance a common element to the explanations of these differences is how well investors both shareholders and creditors are protected by law from expropriation by the managers and controlling shareholders of firms we describe the differences in laws and the effectiveness of their enforcement across countries discuss the possible origins of these differences summarize their consequences and assess potential strategies of corporate governance reform we argue that the legal approach is a more fruitful way to understand corporate governance and its reform than the conventional distinction between bank centered and market centered financial systems

the development of private fresh produce safety standards implications for developing mediterranean exporting countries integration into global markets offers the potential for more rapid growth and poverty reduction for poorer countries however market barriers within advanced economies to agricultural imports have made it harder for developing countries to take full advantage of this opportunity this article examines the impact of increasing demands for food safety and quality by european food retailers and how the fundamental structure and culture of supplier organisations required by european retail chains are a major entry barrier for developing mediterranean fresh produce exporting countries and for developing countries in general the long term solution for such countries to sustain an international demand for their products lies in structural strategic and procedural initiatives that build up the trust and confidence of importers retailers in the quality and safety assurance mechanisms for their produce

what can wages and employment tell us about the uk s productivity puzzle as in many european countries labour productivity in the uk has been stagnant since the start of the great recession this article uses individual data on employment and wages to try to understand whether real wage flexibility can help shed light on the uk s productivity puzzle it finds perhaps unsurprisingly that workforce composition cannot explain the reduction in wages and hence productivity that we observe even compared to previous recessions instead real wages have fallen significantly within jobs this time round why one possibility we investigate is that the labour supply in the uk is higher compared to previous recessions

optimal wholesale facilities location within the fruit and vegetables supply chain with bimodal transportation options an lp mip heuristic approach abstract population growth creates a challenge to food availability and access to balance supply with growing demand more food has to move from production to consumption sites moreover demand for locally grown food is increasing and the u s department of agriculture usda seeks to develop and strengthen regional and local food systems this article examines wholesale facility hub locations in food supply chain systems on a national scale to facilitate the efficient transfer of food from production regions to consumption locations it designs an optimal national wholesale or hub location network to serve food consumption markets through efficient connections with production sites the mathematical formulation is a mixed integer linear programming milp problem that minimizes total network costs which include costs of transporting goods and locating facilities a scenario study is used to examine the model s sensitivity to parameter changes including travel distance hub capacity transportation cost etc an application is made to the u s fruit and vegetable industry we demonstrate how parameter changes affect the optimal locations and number of wholesale facilities

implications of an economic theory of conflict hindu muslim violence in india we model intergroup conflict driven by economic changes within groups we show that if group incomes are low increasing group incomes raises violence against that group and lowers violence generated by it we then apply the model to data on hindu muslim violence in india our main result is that an increase in per capita muslim expenditures generates a large and significant increase in future religious conflict an increase in hindu expenditures has a negative or no effect these findings speak to the origins of hindu muslim violence in post independence india

food safety issues and fresh food product exports from ldcs fresh food products have a high income elasticity of demand and few traditional trade barriers in high income markets as such they represent an important opportunity for less developed country ldc exporters fresh food product exports account for half of all food and agricultural exports from ldcs to high income countries but these products may be subject to greater food safety risks and potential trade barriers arising from sanitary regulation this paper reviews the challenges and issues facing ldcs in meeting food safety standards for export these issues include a the importance of fresh food product trade by region and the kinds of issues that arise from those products b the role of farm to table approaches and hazard analysis critical control points haccp in ensuring safety c the role of the public sector in ldcs in facilitating trade d the potential role of the sps agreement in resolving disputes and determining equivalency of standards between high and low income countries
