crime and poverty a search theoretic approach numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities we study this phenomenon in the context of a search equilibrium model in which agents choose between formal employment and pursuing crimerelated activities theft prior to their occupational choices agents undertake costly schooling raising their productivity crime acts in essence as a tax on human capital by affecting the probability that a worker s earnings possessions are subsequently appropriated there are multiple equilibria high crime low levels of educational attainment long spells of unemployment and poverty are correlated across them

the aftermath of financial crises a look on human and social wellbeing summary alongside its detrimental macroeconomics impacts financial crises can have substantial negative consequences on human and social wellbeing employing a cross country dataset on more than 100 banking and or currency crises during 1981 2007 this work examines the effects of financial crises on indicators of human and social wellbeing through employing an event study analysis the findings of this analysis suggest that the aftermaths of financial crises are characterized by increases in the growth rates of suicide rates crime rates and income inequality rates relative to their pre crisis trajectories additionally declines in the growth rates of health and educational expenditures government welfare expenditures and food quality and quantity intakes are common during periods immediately following financial crises such deteriorations are observed across different countries with income levels and also for crises that are and are not accompanied by recessions on average though human and social indicators are hit harder during financial crisis events accompanied by recessions this is especially true for crises in low and middle income economies in comparison to those in high income countries as a result not only are financial crises directly responsible for more rapid increases in income inequality within countries they may also be responsible for increasing inequalities of income security health nutrition and educational outcomes between richer and poorer countries needless to say deteriorations in many of these fronts are often associated with persistent or permanent losses in human and social wellbeing and cannot be assumed to be simply and immediately reversed with an economic recovery therefore the paper calls on the need for more concerted effort on the part of the policymakers to actively protect human and social outcomes during financial crises rather than trying to address such losses in the aftermath of crises because some of these losses are simply not recoverable

income distribution police expenditures and crime a political economy perspective in this paper i present a structural approach to investigate empirically the relation between income distribution police expenditures and crime the approach is based on the estimation of an equilibrium model where heterogeneous individuals choose whether to engage in criminal activities and expenditures on police to apprehend criminals are determined endogenously through majority voting i discuss the identification and estimation of the parameters of the structural model using data for the united states jel d72 d78 k42

crime rates and local labor market opportunities in the united states 1979 1997 the labor market prospects of young unskilled men fell dramatically in the 1980s and improved in the 1990s crime rates show a reverse pattern increasing during the 1980s and falling in the 1990s because young unskilled men commit most crime this paper seeks to establish a causal relationship between the two trends previous work on the relationship between labor markets and crime focused mainly on the relationship between the unemployment rate and crime and found inconclusive results in contrast this paper examines the impact of both wages and unemployment on crime and uses instrumental variables to establish causality we conclude that both wages and unemployment are significantly related to crime but that wages played a larger role in the crime trends over the last few decades these results are robust to the inclusion of deterrence variables controls for simultaneity and controlling for individual and family characteristics

inequality and violent crime abstract we investigate the robustness and causality of the link between income inequality and violent crime across countries first we study the correlation between the gini index and homicide and robbery rates within and between countries second we examine the partial correlation by considering other crime determinants third we control for the endogeneity of inequality by isolating its exogenous impact on these crime rates fourth we control for measurement error in crime rates by modeling it as both unobserved country effects and random noise finally we examine the robustness of this partial correlation to alternative measures of inequality the panel data consist of nonoverlapping 5 year averages for 39 countries during 1965 95 for homicides and 37 countries during 1970 94 for robberies crime rates and inequality are positively correlated within countries and particularly between countries and this correlation reflects causation from inequality to crime rates even after controlling for ot

determinants of violent and property crimes in england and wales a panel data analysis we examine various determinants of property and violent crimes by using police force area level pfa data on england and wales over the period of 1992 2008 our list of potential determinants includes two law enforcement variables namely crime specific detection rate and prison population and various socio economic variables such as unemployment rate real earnings proportion of young people and the gini coefficient by adopting a fixed effect dynamic gmm estimation methodology we attempt to address the potential bias that arises from the presence of time invariant unobserved characteristics of a pfa and the endogeneity of several regressors there is a significant positive effect of own lagged crime rate the own lagged effect is stronger for property crime on an average than violent crime we find that on an average higher detection rate and prison population leads to lower property and violent crimes this is robust to various specifications however socio economic variables with the exception

earthquake fatalities the interaction of nature and political economy to say that the level of fatalities resulting from an earthquake is inversely related to a country s per capita level of income is hardly novel what makes our approach novel is that we relate fatalities to both per capita income and the level of inequality that exists within a country through their joint impact on the likelihood of collective action being taken to mitigate the destructive potential of quakes we first develop a theoretical model which offers an explanation as to why in some environments different segments of society prove incapable of arriving at what all parties perceive to be an agreeable distribution of the burden of the necessary collective action causing the relatively wealthy simply to self insure against the disaster while leaving the relatively poor to its mercy following this we test our theoretical model by evaluating 269 large earthquakes occurring worldwide between 1960 and 2002 taking into account other factors that influence a quake s destructiveness such as its magnitude depth and proximity to population centers using a negative binomial estimation strategy with both random and fixed estimators we find strong evidence of the theoretical model s predictions that is while earthquakes themselves are natural phenomena beyond the reach of humankind our collective inaction with respect to items like the creation and enforcement of building codes failure to retrofit structures and to enact quake sensitive zoning clearly plays a part in determining the actual toll that a given quake takes and it is through these and other examples of collective inaction that limited per capita income and inequality couple together with a given quake s natural destructive power in determining the actual fatalities resulting from a quake

operations research for green logistics an overview of aspects issues contributions and challenges the worldwide economic growth of the last century has given rise to a vast consumption of goods while globalization has led to large streams of goods all over the world the production transportation storage and consumption of all these goods however have created large environmental problems today global warming created by large scale emissions of greenhouse gasses is a top environmental concern governments action groups and companies are asking for measures to counter this threat operations research has a long tradition in improving operations and especially in reducing costs in this paper we present a review that highlights the contribution of operations research to green logistics which involves the integration of environmental aspects in logistics we give a sketch of the present and possible developments focussing on design planning and control in a supply chain for transportation inventory of products and facility decisions while doing this we also indicate several areas where environmental aspects could be included in or models for logistics

bank mergers and crime the real and social effects of credit market competition using a unique sample of commercial loans and mergers between large banks we provide micro level within county evidence linking credit conditions to economic development and find a spillover effect on crime neighborhoods that experience more bank mergers are subject to higher interest rates diminished local construction lower prices an influx of poorer households and higher property crime in subsequent years the elasticity of property crime with respect to merger induced banking concentration is 0 18 we show that these results are not likely due to reverse causation and confirm the central findings using state branching deregulation to instrument for bank competition we examine the real and social impact of local credit competition by documenting a link between the competitiveness of the local banking market credit conditions urban development and crime several recent studies peek and rosengren 2000 cetorelli and gambera 2001 klein peek and rosengren 2002 and burgess and pande 2003 tie credit market imperfections to diminished real economic activity and growth other studies connect the economic environment to property crime freeman 1999 levitt 2001 raphael and winter ebmer 2001 and nilsson 2004 it is reasonable to hypothesize therefore that reductions in bank competition may lead to economic decline and subsequently increases in property crime we empirically investigate the effects of bank consolidation and increased market power on credit availability and real activity using a unique sample of commercial loans and mergers between large banks in the 1990s we provide micro level evidence that garmaise is from the ucla anderson school and moskowitz is from the graduate school of business university of chicago and nber we have benefited from the suggestions and comments of tony bernardo marianne bertrand phillip bond doug diamond mark duggan eugene fama

economic determinants of land invasions this study estimates the effect of economic conditions on redistributive conflict we examine land invasions in brazil using a panel data set with over 50 000 municipality year observations adverse eco nomic shocks instrumented by rainfall cause the rural poor to invade and occupy large landholdings this effect exhibits substantial heterogeneity by land inequality and land tenure systems but not by other observable variables in highly unequal municipalities negative income shocks cause twice as many land invasions as in municipalities with average land inequality cross sectional estimates using fine within region variation also suggest the importance of land inequality in explaining redistributive conflict i introduction c onflict over land is endemic to many rural econo mies in environments marked by a highly skewed distribution of property incomplete land and credit markets poorly or unevenly enforced property rights and weak political institutions agents often resort to extralegal means to improve their economic positions the poor frequently invade private properties and occupy them until either forcibly expelled or granted official titles land conflict which is prevalent in many countries such as brazil south africa uganda and venezuela may distort the allocation of resources in the agricultural sector away from productive uses and thereby contribute to the persistence of rural poverty how do economic conditions affect this redistrib utive conflict this paper explores this question using a rich municipal level data set of 5 299 land invasions from 1988 to 2004 in brazil we follow miguel satyanath and sergenti 2004 by using rainfall as a source of exogenous variation to study the relationship between income and conflict and we find that adverse economic shocks cause the rural poor to invade large landholdings this effect exhibits considerable het erogeneity by land inequality and land tenure systems in highly unequal municipalities negative income shocks cause twice as many land invasions as in municipalities with average land inequality the effect of income shocks is even stronger in highly polarized municipalities as measured by the degree of bimodality in the land distribution cross sectional estimates using fine within region variation also suggest the importance of land inequality in explaining redistributive conflict we also find that income shocks cause significantly more land invasions in municipalities with a greater proportion of land under fixed rent contracts by contrast we find no evidence of heterogeneity on a range of other political and socioeconomic variables including political competition sharecropping police expenditures and social welfare spending recent microeconometric studies have examined two

is economic growth improving urbanisation a cross regional study of china this study applies a bootstrap panel granger causality test to determine the relationship between urbanisation and economic growth for china we find that the patterns of interaction between urbanisation and economic growth vary across different regions the empirical results show that in urbanisation of the northern coastal region and most of the inland region granger causes economic growth whereas economic growth does not have a significant effect on urbanisation except in the southern coastal region and the inland region one fourth of china s provinces primarily in the southern coastal region do not show a granger causality relationship between urbanisation and economic growth this finding indicates that urbanisation has promoted economic growth by expanding demand and that economic growth s effect on urbanisation is restricted by administrative intervention rather than market mechanisms thus the findings for three fourths of the provinces in china conform to the urbanised economy theory these

a dynamic model of differential human capital and criminal activity this paper presents a dynamic model of criminal activity individuals are endowed with legal and criminal human capital potential incomes in legal and criminal sectors depend on the level of the relevant human capital the rate of return and random shocks human capital can be enhanced by participating in both sectors legal human capital can also be enhanced through investment human capital is subject to depreciation individuals maximize expected discounted lifetime utility which depends on consumption the model allows analyses of the effects of recessions imprisonment rehabilitation scenarios sanctions and returns to human capital new insights such as hysteresis in criminal behaviour are obtained

using electoral cycles in police hiring to estimate the effect of police on crime comment previous empirical studies have uncovered little evidence that police reduce crime possibly due to simultaneity problems this paper uses the timing of mayoral and gubernatorial elections as an instrumental variable to identify a causal effect of police on crime increases in the size of police forces are shown to be disproportionately concentrated in mayoral and gubernatorial election years increases in police are shown to substantially reduce violent crime but have a smaller impact on property crime the null hypothesis that the marginal social benefit of reduced crime equals the costs of hiring additional police cannot be rejected

mixed markets and crime abstract this paper specifies and solves a two stage game theoretic model of a mixed market for crime control in the first stage of the model private targets and the government choose levels of policing in the second stage criminals choose targets and the severity of the crimes that they commit the paper s key results are as follows first private policing can both divert crime to targets that lack private protection and also increase the severity of the crime that these less protected targets suffer second an increase in private policing reduces the aggregate expenditure on traditional policing this is an instance of a political incentive externality where private policing affects the objective function of the government specifically it reduces the level of traditional policing that is consistent with the samuelson condition for efficient provision of a public good third the substitution of private for public policing carries with it a change in the technology of policing in effect private policing leads to a shift from enforcement and punishment towards monitoring and target hardening this in turn may lead to an increase in the severity of crime fourth the mixed policing equilibrium is inefficient and in some situations mixing may reduce the utility of all targets

help wanted economists crime and public policy beginning with gary w becker s 1968 article on crime and punishment economists have contributed important theoretical insights and empirical findings to the study of criminal behavior but the influence of economists on crime relevant research and over policy debates remains negligible this essay summarizes some basic data on the causes of crime the social costs and benefits of incarceration and replenishing social capital work on crime by economists should become influential in setting research agendas and shaping policy debates but economists will have to roll up their sleeves complexify their models and confront a real world prisoner s dilemma or two

return migration and violence abstract there is reason to suspect that return migrants can reduce social violence in migrant prone regions of the world taking into account that recent research shows positive effects of return migration we consider that returners may reduce violence by contributing to social renewal and economic growth in their home communities we estimate the direct effects of return migration in the context of mexico a traditionally migrant country that has suffered record levels of violence in the past decade using data on homicide rates from 2456 municipalities for the 2011 2013 period and an instrumental variable bivariate tobit maximum likelihood approach we find that higher rates of return migration lead to a decline in local homicide rates we also show with a censored quantile instrumental variable cqiv model that municipalities in the bottom quartile of the homicide rate distribution benefit the most from return migration our work has important implications for crime reduction policies in developing countries and specifically in mexico where social violence has wreaked havoc on society in recent years

the sopranos redux the empirical economics of waste crime almer c and goeschl t the sopranos redux the empirical economics of waste crime regional studies evidence for the argument that enforcement makes environmental policies effective is limited with respect to geography scope enforcement tools and regulatory context non us evidence on criminal enforcement of illegal waste disposal is examined using a panel dataset of 44 counties from the german state of baden wurttemberg for the period 1995 2005 the results support the pro enforcement argument cumulatively there is clear evidence for a general deterrence effect of enforcement intensity on the amount of waste crime however regional economic and political economy factors matter significantly for environmental outcomes violations appear to be treated differently depending on their local political economy context

crime and local inequality in south africa the authors examine the effects of local inequality on property and violent crime in south africa their findings are consistent with economic theories relating inequality to property crime and also with sociological theories that imply that inequality leads to crime in general burglary rates are 20 30 percent higher in police station jurisdictions that are the wealthiest among their neighbors suggesting that criminals travel to neighborhoods where the expected returns from burglary are highest the authors do not find evidence that inequality between racial groups fosters interpersonal conflict at the local level

design of sustainable supply chains under the emission trading scheme increase in environmental concerns together with legislations are forcing industries to take a fresh look at the impact of their supply chain operations on the environment this paper introduces a mixed integer linear programming based framework for sustainable supply chain design that considers life cycle assessment lca principles in addition to the traditional material balance constraints at each node in the supply chain indeed the framework distinguishes between solid and liquid wastes as well as gaseous emissions due to various production processes and transportation systems the framework is used to evaluate the tradeoffs between economic and environmental objectives under various cost and operating strategies in the aluminum industry the results suggest that current legislation and emission trading schemes ets must be strengthened and harmonized at the global level in order to drive a meaningful environmental strategy moreover the model demonstrates that efficient carbon management strategies will help decision makers to achieve sustainability objectives in a cost effective manner

crime and victimization an economic perspective the recent upward trend in crime rates of developing countries has spurred widespread public concern about personal and proprietary insecurity in some countries the questions of crime violence and victimization are attracting more attention from academics and policy makers than traditional economic problems the objective of this paper is to examine the main issues related to crime and victimization from an economic perspective for this purpose the paper combines a review of the main results established in the literature with original research on the causes of crime and the risk factors of victimization the first section provides a review of the estimates of the costs of crime the main theoretical and empirical research on its causes and the relative advantages of official and survey data on crime the second section presents original work on the main causes of violent crime from a cross country perspective the empirical work starts with a basic model of the economic determinants of homicide and robbery rates in turn this empirical model is extended along five dimensions 1 deterrence factors 2 illegal drug related activities 3 demographic issues 4 income and ethnic polarization and 5 social capital the third section reviews recent case studies of latin american cities that rely on survey data to assess the empirical determinants of the probability of victimization these studies focus on three types of risk factors 1 individual characteristics 2 household characteristics and 3 community characteristics the main conclusions from the previous sections are summarized in section four

inequality and crime this paper considers the relationship between inequality and crime using data from urban counties the behavior of property and violent crime are quite different inequality has no effect on property crime but a strong and robust impact on violent crime with an elasticity above 0 5 by contrast poverty and police activity have significant effects on property crime but little on violent crime property crime is well explained by the economic theory of crime while violent crime is better explained by strain and social disorganization theories

carbon footprint and responsiveness trade offs in supply chain network design concern related to sustainability and greenhouse gases has grown among citizens as well as firms which are increasingly committing to carbon emission reduction targets however firms emissions come from direct and indirect sources and from the different stages of their supply chain therefore comprehensive supply chain approaches are essential to ensure the cost effectiveness of carbon management strategies these approaches should capture operational and environmental trade offs arising from the interaction between different supply chain processes such as procurement manufacturing transport and inventory management considering all these processes we propose a model for supply chain network design that takes demand uncertainty into account and includes decisions on supply chain responsiveness under different carbon policies caps on supply chain carbon footprints caps on market carbon footprints and carbon taxes our model supports the analysis of the effect of different policies on costs and optimal network configuration and allows us to distinguish between different product types functional or innovative products with detailed numerical examples we illustrate the type of analysis and managerial insights that can be derived with our model which include the assessment of supply chains potential for carbon abatement the study of the effect of different carbon policies on supply chain costs and network design the analysis of the impact of various product characteristics the test of an alternative profit maximisation model and the determination of the value of a supply chain carbon tax that should induce specific levels of carbon abatement

environmental crime and punishment empirical evidence from the german penal code u s and e u environmental policy employ criminal sanctions to enforce compliance recent moves toward revising their use are based on little empirical evidence as to their effectiveness this paper exploits a unique dataset to study the deterrent effect of criminal enforcement the dynamic panel data analysis leads to three findings first criminal sanctions do provide the intended deterrent effects second standing trial provides one of the most significant deterrents rather than the probability of conviction or the magnitude of fines third public preferences regarding environmental quality and political economy variables affect reported environmental crime

crime and social interactions the high variance of crime rates across time and space is one of the oldest puzzles in the social sciences this variance appears too high to be explained by changes in the exogenous costs and benefits of crime we present a model where social interactions create enough covariance across individuals to explain the high cross city variance of crime rates this model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes moderate in more serious crimes and almost negligible in murder and rape

crime and growth convergence evidence from mexico scholars have often argued that crime deters growth but the empirical literature assessing such effect is scarce by exploiting cross municipality income and crime data for mexico a country that experienced a high increase in crime rates over the past decade this study circumvents two of the most common problems faced by researchers in this area these are i the lack of a homogenous consistently comparable measure of crime and ii the small sample problem in the estimation combining income data from poverty maps administrative records on crime and violence and public expenditures data at the municipal level for mexico 2005 2010 the analysis finds evidence indicating that drug related crimes indeed deter growth it also finds no evidence of a negative effect on growth from crimes unrelated to drug trafficking

income inequality and violent crime evidence from mexico s drug war the relationship between income inequality and crime has attracted the interest of many researchers but little convincing evidence exists on the causal effect of inequality on crime in developing countries this paper estimates this effect in a unique context mexico s drug war the analysis takes advantage of a unique data set containing inequality and crime statistics for more than 2 000 mexican municipalities covering a period of 20 years using an instrumental variable for inequality that tackles problems of reverse causality and omitted variable bias this paper finds that an increment of one point in the gini coefficient translates into an increase of more than 10 drug related homicides per 100 000 inhabitants between 2006 and 2010 there are no significant effects before 2005 the fact that the effect was found during mexico s drug war and not before is likely because the cost of crime decreased with the proliferation of gangs facilitating access to knowledge and logistics lowering the marginal cost of criminal behavior which combined with rising inequality increased the expected net benefit from criminal acts after 2005

scale externalities in korea this paper estimates the nature and magnitude of scale externalities in a developing country korea in the period 1983 1993 this is a period of rapid industry deconcentration from seoul to other metro areas providing a context where externalities are measured when local scale magnitudes are changing dramatically the data allow us to examine the emerging degree of national industrial concentration in different industries as related to their scale externality magnitudes we also examine whether individual industries agglomerate in cities which have a comparative advantage for that industry

on the political economy of income redistribution and crime this article analyzes a general equilibrium model in which agents choose to specialize in either legitimate or criminal activities expenditures on police to apprehend criminals as well as income redistribution are determined endogenously through majority voting we investigate how crime redistribution and police expenditures depend on characteristics of the underlying distribution of income earning abilities and on the apprehension technology our model accounts for the positive correlation between inequality and crime the positive correlation between expenditures on police and redistribution and the lack of correlation between crime and redistribution observed in u s data

does globalisation affect crime theory and evidence globalization skeptics argue that trade liberalization has high social costs including an increase in expropriative behavior such as civil conflict coercion of labor and crime we show that a theoretical relationship between trade and expropriation exists but the sign differs for developed and developing economies we verify this empirically using data on crime rates specifically we find trade liberalization as measured by both higher openness and lower import duty rates tends to increase burglaries and theft in very labor abundant countries for other countries however we find that trade liberalization has either a small negative effect on crime or no effect depending on the country s capital abundance

ecological deficit tax a tax design and simulation of compensation for ecosystem service value based on ecological footprint in china abstract the expansion of resource tax to the occupation of natural ecological space is an important part of china s tax reform this paper quantifies the occupation of natural ecological space based on the demand for energy water and agriculture resources in terms of an ecological footprint and creatively convert the carbon emissions from energy consumption to occupation of carbon sinks such as woodlands and grasslands to obtain the ecological deficits in various regions of china based on the evaluation of the ecological service value the paper determines the correspondence between consumption projects land types and ecological functions realized the accounting of the economic value of the national ecological deficit as the sum of the regional deficits based on this the ecological deficit is used as an unpaid input factor in the construction of a green social accounting matrix table and a recursive dynamic computable general equilibrium model is used to analyze the effects of a tax policy on the compensation for the ecological deficit value the simulation results show that the double dividend hypothesis exists in the primary and tertiary industries and employment in the secondary industry that with a high value added labor decreased resulting in decreases in both the labor income of residents and their proportion of the national income the growth rate of gdp decreases in the short term and then gradually increases capital appreciation and net exports contribute greatly to economic growth based on the positive role of taxation schemes in reducing ecological deficits and their negative impacts on economic growth and the income distribution this paper suggests that with the improvement of big data on ecological occupation an ecological deficit tax can be introduced to target the energy sector which has a large ecological footprint in addition household income should be protected through tax cuts transfer payments and earmarked funds among other means to promote economic growth and protect the environment

the power of money wealth effects in contests abstract the relationship between wealth and power has long been debated nevertheless this relationship has been rarely studied in a strategic game in this paper we study wealth effects in a strategic contest game two opposing effects arise wealth reduces the marginal cost of effort but it also reduces the marginal benefit of winning the contest we consider three types of contests which vary depending on whether rents and efforts are commensurable with wealth our theoretical analysis shows that the effects of wealth are strongly contest dependent it thus does not support general claims that the rich lobby more or that low economic growth and wealth inequality spur conflicts

input measurement and productivity growth in japanese and u s manufacturing in their article in this review j r norsworthy and david h malmquist 1983 have presented interesting comparisons of productivity growth in the japanese and u s manufacturing sectors their paper starts with the discussion of whether the conventional value added or gnp measurement of output is an appropriate framework for productivity analysis some confusion frequently arises as to whether a production function should be structured on the basis of gross output or value added output separability is a pivotal concept in the analysis of production structures especially in relation to the existence of a real value added aggregate it is well known that there are two types of separability which pertain to the existence of a real value added function weak local separability and strong partial separability the practical advantage of distinguishing these two different forms of separability is that the double deflation method in conventional gnp accounting is justified only when strong partial separability holds using the approximate separability tests of michael denny and melvyn fuss 1977 norsworthy and malmquist have shown that a value added aggregate does not exist in either u s or japanese manufacturing and they conclude that the appropriate output measure for joint investigation of both countries for purposes of productivity analysis is gross output p 953 the purpose of this comment is to indicate some deficiencies in norsworthy and malmquist s analysis in particular it will be demonstrated that the conditions for weak local and strong partial separability in norsworthy and malmquist s paper are incorrectly formulated and as a consequence their findings may not be used as conclusive evidence that a gross output measure is an appropriate basis for the analysis of capital labor substitutability and productivity growth in japan and the united states

the effect of rising income inequality on taxation and public expenditures evidence from u s municipalities and school districts 1970 2000 the income distribution in many developed countries widened dramatically from 1970 to 2000 some scholars argue that income inequality contributes to a host of social ills by undermining voters will ingness to support public expenditures in contrast we find that growing income inequality is associated with an expansion in government reven ues and expenditures on a wide range of services in u s municipalities and school districts results are robust to a number of model specifica tions including instrumental variables that address the endogeneity of the local income distribution our results are inconsistent with models pre dicting that heterogeneous societies provide lower levels of public goods public sector 3 two types of identification problems com plicate estimation of the empirical relationship between income inequality and public goods provision the cross country variation often used for this exercise suffers from omitted variable bias that is countries with high income inequality may also have other characteristics that could limit the size of the public sector cross state comparisons also suffer from endogenous household sorting if low or high income families migrate to states with high public expenditures the positive association observed in the litera ture between state public expenditures and income inequal ity may be spurious in this paper we examine the relationship between income inequality and government finances in municipali ties and school districts in the united states from 1970 to 2000 local government represents a large segment of the economy in fiscal year 2009 local governments disbursed more than 3 trillion for such important services as educa tion and public safety 4 our study has several advantages over existing empirical work first the large number of local governments in our data exhibit much greater variation in income inequality over time than do the small number of countries or states used in previous studies a large sample size allows us to separately control for changes in the top end or bottom end of the income distribution and for initial levels of inequal ity thus ruling out a mechanical association between tax revenues and rising income for the affluent second we develop an instrumental variable strategy to mitigate con cerns about potential reverse causality from the endogenous

incentive and incarceration effects in a general equilibrium model of crime an intertemporal general equilibrium model of criminal behavior is used to analyze the effect on crime of changing policy parameters the policy parameters are the length of the prison term the severity of punishment and the amount of police resources the number of crimes in society can be decomposed into an incentive part an incarceration part and a crime competition part the magnitudes of these three components are studied by means of empirical data from england and the us

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

learning from the behavior of others conformity fads and informational cascades learning by observing the past decisions of others can help explain some otherwise puzzling phenomena about human behavior for example why do people tend to converge on similar behavior why is mass behavior prone to error and fads the authors argue that the theory of observational learning and particularly of informational cascades has much to offer economics business strategy political science and the study of criminal behavior

the effect of prison population size on crime rates evidence from prison overcrowding litigation simultaneity between prisoner populations and crime rates makes it difficult to isolate the causal effect of changes in prison populations on crime to break that simultaneity this paper uses prison overcrowding litigation in a state as an instrument for changes in the prison population the resulting elasticities are two to three times greater than those of previous studies a one prisoner reduction is associated with an increase of fifteen index i crimes per year while calculations of the costs of crime are inherently uncertain it appears that the social benefits associated with crime reduction equal or exceed the social costs of incarceration for the marginal prisoner

alcohol availability and crime evidence from census tract data 1 introduction this article uses census tract data from the city of detroit and a reduced form crime equation to investigate the effects of alcohol availability on crime a fact of urban life in the united states is high crime rates rates that differ across neighborhoods in cities and easy availability of alcohol a disproportionately large number of crimes are committed by people who have just consumed alcohol cook and moore 1993a the homicide rate among youths in poor inner cities where alcohol consumption tends to be high is four times as high as the national average among all youths fbi 1996 parker 1993 reports that all things equal homicides are higher in high alcohol consumption neighborhoods than in low alcohol consumption neighborhoods according to the national institute of criminal justice statistics 40 of all violent crime victimization 40 of all fatal motor vehicle accidents and 67 of all domestic violence in 1995 were alcohol related in addition 40 of all violent offenders in jail reported using alcohol just before committing the crime greenfeld 1998 similarly a disproportionately large share of crimes in the united kingdom occurs in or near pubs during peak hours of operation hutchinson henderson and davis 1995 besides being perpetrators a large number of victims of crime had used alcohol at the time of their victimization in this study i use the term commission of crime more broadly to include perpetrators as well as the victims of crime in spite of these statistics easy availability of alcohol and its use continue to be part of the american culture a harris poll reports that 38 of adult males think they drink too much but will not change their behavior and 28 of high school students think that adults should be able to drink all the alcohol they want fbi 1996 however a recent study conducted by the university of michigan for the national institute of drug abuse found that over 80 of americans disapprove of youth drinking university of michigan institute for social research 1998 in spite of these statistics linking alcohol to crime with the exception of the relationship between alcohol control policy and drunk driving economists have not investigated the effects of alcohol availability on crime rates generally given the high correlation between alcohol availability and crime dilulio 1995 suggests using zoning laws to decrease alcohol availability as a means of decreasing crime it is not clear whether there is a causal relationship between alcohol availability and crime rates does alcohol availability increase crime if increased alcohol availability leads to increased crime what is the mechanism through which alcohol availability affects crime while answers to these questions may be important for policy formulation and implementation my concern is with the investigation of the effects of alcohol availability on crime rates if alcohol availability increases crime rates it may be possible to formulate alcohol control policies that also depress crime while there are few theoretical models that link alcohol availability to specific crimes empirical studies of the effects of geographical availability of alcohol on crime rates generally are few and far between in the economics literature more empirical studies could help establish the link that has been made between alcohol control policies and crime results of studies investigating the connection between alcohol availability and crime have implications for further research and policy for example if alcohol availability increases crime rates then decreasing alcohol availability may decrease crime and improve social welfare if there is a positive link between alcohol availability and crime rates then alcohol availability should be included in the supply of offense equation as an added explanatory variable there is therefore the need to better understand the relationship between the geographical availability of alcohol and crime rates in the economics of crime literature

gated communities and the economic geography of crime abstract this paper analyzes gated communities in a geographic model of crime there are four major results first gating always diverts crime to other communities but has an overall deterrent effect on crime as long as it does not impact legitimate employment opportunities second gating expenditures may be strategic substitutes or strategic complements the latter possibility may help explain why gated communities appear to spread like a contagion third the nash equilibrium level of gating expenditures is inefficiently large fourth gating may actually increase the overall level of crime if it either affects employment opportunities or it influences the selection among multiple equilibrium crime rates

income inequality and crime in the united states abstract this paper investigates the relationship between income inequality and crime results show that there is a strong and robust effect of relative income inequality on burglary effect on robbery is also strong and robust in most cases

the distribution of public services an exploration of local governmental preferences a local governmental welfare function is specified to explore two of its central characteristics the equity productivity trade off and differential weights across neighborhoods the constrained maximization model is estimated using service outcomes safety in the welfare function as opposed to publicly provided inputs police over neighborhoods the equity productivity trade off is found to be considerable and not all neighborhoods are weighted equally the results show that inequality aversion and unequal concern by local government over service outcomes must be addressed explicitly to understand the observed distribution of publicly provided inputs with important implications for standard analysis of local governmental behavior copyright 1987 by american economic association

poverty and witch killing many observers have noted that poverty and violence go hand in hand there is a strong negative relationship between economic growth and crime across countries as well as across districts in india and a link between low income and the occurrence of civil war 1 yet existing studies are typically unable to resolve the key econometric identification issues of omitted variable bias and endogeneity to illustrate the unobserved quality of local government institutions may affect both income growth and crime rates and poverty could lead to violence if desperate people with nothing to lose commit more crimes but violence itself may in turn affect economic productivity this paper uses local rainfall variation to identify the impact of income shocks on murder in a rural tanzanian district 2 extreme rainfall resulting in drought or floods is exogenous and is associated with poor harvests and near famine conditions in the region and a large increase in the murder of witches there are twice as many witch murders in years of extreme rainfall as in other years the victims are nearly all elderly women typically killed by relatives these econometric results across 11 years in 67 villages provide novel evidence on the role of income shocks in causing violent crime and religious violence in particular and also provide insights into witchcraft an important social phenomenon in africa rarely studied by economists the view that economic conditions are a driving force behind witch murders is bolstered by the fact that most witch killing in tanzania takes place in poor rural areas largely dependent on rain fed agriculture and that most victims in our sample are from poor households however it is difficult to definitively disentangle this income shock theory from alternative socio cultural explanations the concentration of tanzanian witch murders in a region dominated by one particular ethnic group the sukuma and the especially high number of witch murders in villages where indigenous religious beliefs are strong both point to the important role of non economic factors economic theories and cultural theories are perhaps best viewed as complements the empirical findings demonstrate the power of economics to rationalize a phenomenon that has previously been understood almost solely through a socio cultural lens 3

industrial bases and city sizes away from heavy manufacturing and bluecollar occupations and towards professional activities communications finance insurance real estate and high tech activities should we expect these gains and losses to be spread across cities or are certain cities likely to be gainers and others losers in terms of population are losers likely to experience permanent declines in population or for some will their losses level off or will they rebound if the growth industries of an economy operate best in larger cities while declining industries tend to reside in smaller cities this implies national population will shift from smaller cities to locating in larger cities this increase in urban concentration means there will be changes in other patterns of resource usage efficient levels of per capita resources devoted to urban infrastructure roads sewers parks etc tend to rise with city size and it is a common perception that the magnitudes of certain consumer externalities congestion air and water pollution crime etc rise with city size this has implications for public policies governing the allocation of public investment and governing the regulation of externalities moreover the changes in population allocation between larger and smaller cities itself involves to some extend a painful process of population upheavals and there may be public policies which can alleviate the costs of the adjustment process in this paper i outline a conceptual framework and empirical methodologies from which some of these issues can be examined

a structural model of crime and inequality in colombia economic theory suggests that inequality should influence crime positively yet the evidence in favor of that hypothesis is weak pure cross sectional analyses show significant positive effects but cannot control for fixed effects time series and panel data point to a variety of results but few turn out being significant the hypothesis maintained in this paper is that it is a specific part of the distribution rather than the overall distribution as summarized by conventional inequality measures that is most likely to influence the rate of property crime in a given society using a simple theoretical model and panel data in seven colombian cities over a fifteen year period a structural model is proposed that permits identifying the precise segment of the population whose relative income best explains time changes in crime jel k42 d63 o15

violent crime and punishment an application of the lisrel model public anxiety over violent crime has forged a broad consensus to purchase more crime control recently the president brought into law a federal anti crime bill that will put an additional 100 000 police on the nation s streets this paper presents empirical evidence on the deterrence effect of police presence the principal finding is that police presence deters commission of violent crimes by increasing the risk of being punished for committing those crimes this risk is modelled as a latent variable because the probability and severity of punishment for committing a violent crime are generally communicated in an onconsistant fashion the violent crime commission rate is also treated as a latent variable because it is almost certainly afflicted with measurement error

managing carbon footprints in inventory management abstract there is a broad consensus that mankind must reduce carbon emissions to mitigate global warming it is generally accepted that carbon emission trading is one of the most effective market based mechanisms to curb the amount of carbon emissions this paper investigates how firms manage carbon footprints in inventory management under the carbon emission trading mechanism we derive the optimal order quantity and analytically and numerically examine the impacts of carbon trade carbon price and carbon cap on order decisions carbon emissions and total cost we make interesting observations from the numerical examples and provide managerial insights from the analytical results

environmental safety stock the impacts of regulatory and voluntary control policies on production planning inventory control and environmental performance abstract this paper analyzes the impacts of different pollution control policies on a firm s decisions of production planning and inventory control based on a stochastic model with both demand and environmental uncertainties we derive the optimal policies of production planning and inventory control under both regulatory and voluntary pollution control approaches and investigate their operational and environmental effects we establish that the conventional wisdom which suggests that reduction of environmental waste at the end of a production process also decreases the stock and throughput levels of a production system is not necessarily true rather a regulatory environmental standard that limits the total amount of waste may induce the firm to raise its planned stock level which would lead to a higher expected amount of environmental wastes before the standard is enforced as well as environmental risks at other stages of the production process the additional planned stock level which is termed environmental safety stock can be reversed by using the voluntary control approach that provides the firm with the flexibility to occasionally exceed the environmental standard we also conduct numerical experiments to analyze the effects of different values of model parameters under different control approaches the analytical results provide new insights to the impacts of a firm s production and inventory decisions on the natural environment as well as to the choices of pollution control approaches by decision makers in both the private and public sectors

urbanisation and regional productivity in korean manufacturing as the first study for korea we estimate the effects of urbanisation and localisation economies on the productivity of 19 korean manufacturing industries in 1983 1988 and 1993 based on the observation that material inputs contributed about 60 per cent of productivity growth in korea we consider gross output productivity which is an innovation that distinguishes our study from previous ones we find that localisation economies have been dominant features of korean manufacturing industries whereas korean manufacturing industries did not benefit much from locating in large cities more interestingly there are some indications of quadratic relations between city size and urbanisation economies

crime inequality and unemployment in england and wales a model of crime is developed based on principles from the existing literature with some original insight the implications of the model are that income inequality and unemployment are important explanatory variables for crimes motivated by economic gain but do not offer much explanatory power for other types of crime panel data of uk regions over the years from 2002 to 2007 are then used to test these predictions the empirical results strongly support the hypothesis that crime is an economic phenomenon

increasing returns and the evolution of violent crime the case of colombia abstract this paper presents an explanation of the recent escalation of violent crime in colombia the paper considers three implicit models that isolate different types of externalities among criminals in the first model criminals make crime more appealing to nearby residents by congesting the law enforcement system and hence lowering the probability of punishment in the second model the interaction of career criminals and local crooks speeds up the diffusion of criminal know how and criminal technology in the third model the daily contact of youth with criminal adults and criminal peers results in the erosion of morals and hence in a greater predisposition toward crime the paper shows that a myriad empirical evidence both statistical and anecdotal lends support to the previous models in general and to the congestion in law enforcement model in particular

the welfare cost of violence across countries the cost of violence goes beyond its material dimension including also the welfare loss due to higher mortality a given mortality and its distribution across age groups determines a reduction in life expectancy that can be valued using the marginal willingness to pay approach we estimate the health dimension of the welfare cost of violence for 73 countries on average 1 year of life expectancy lost to violence is associated with a yearly social cost of 3 8 of gdp the health dimension increases the estimated social costs of violence by 40 in the united states and by 57 in latin america

crime induced poverty traps abstract poverty makes thieves and thieves hamper economic growth we study these linkages in a model of modern sector job creation job creation has two effects higher labor demand tends to lower crime while higher output gives more to steal tending to increase crime at low levels of modernization the second effect dominates and as a consequence the model has decreasing returns to scale at higher levels of modernization there is increasing returns to scale due to declining crime the economy may end up in a poverty trap with high crime and low production or obtain full modernization with low crime rates the danger of ending up in a poverty trap has implications for economic policies we show for instance that a reform intended to improve efficiency may throw the economy into a vicious circle of increasing crime and stagnation if implemented too fast

what causes violent crime this study uses panel data of intentional homicide and robbery rates for a sample of developed and developing countries for the period 1970 1994 based on information from the united nations world crime surveys to analyze the determinants of national crime rates both across countries and over time a simple model of the incentives to commit crimes is proposed which explicitly considers possible causes of the persistence of crime over time criminal inertia a panel data based gmm methodology is used to estimate a dynamic model of national crime rates this estimator controls for unobserved country speci ce ects the joint endogeneity of some of the explanatory variables and the existence of some types of measurement errors a icting the crime data the results showthat increases in income inequality raise crime rates crime tends to be countercyclical and criminal inertia is signi cant 2002 elsevier science b v all rights reserved

the determinants of employee crime in the uk we present evidence on employee theft in the uk using data on actual recorded crime in a model where employees are rational cheaters whose theft decisions may also be influenced by individual characteristics we produce hypotheses about the role of labour market deterrence and individual influences on employee theft we then examine the role of these influences using regional crime data supplemented by data from the uk labour force survey and the home office our results provide information on employee theft as a particular type of crime on policy that may help to combat it and on alternative views of the motivation for crime

assessing the impact of cost optimization based on infrastructure modelling on co2 emissions traditionally logistics design is driven by a need to reduce costs and improve customer service recently the environmental concerns from transport have been increasingly discussed the traffic levels and associated energy consumption are influenced by supply chain structure modal split and vehicle utilization this paper aims to assess the impact of the traditional cost optimization approach to strategic modelling on overall logistics costs and co2 emissions by taking into account the supply chain structure number of depots and different freight vehicle utilization ratios 90 75 and 60 the simulation model based on a european case study from the automotive industry considers strategic and operational level decisions simultaneously the analysis shows that the optimum design based on costs does not necessary equate to an optimum solution for co2 emissions therefore there is a need to address economical and environmental objectives explicitly as part of the logistics design

criminal deterrence revisiting the issue with a birth cohort we estimate the general deterrent effect of criminal justice resources on criminal behavior using panel data for a sample representative of young men in u s urban areas our data which combine individual level information on arrests and personal characteristics with aggregate information on criminal justice resources allow us to obtain deterrence measures that reflect theoretical concepts and are of potential policy relevance we find robust evidence of a general deterrent effect flowing from criminal justice particularly police resources the nature of our data also allows us to conduct extensive exogeneity tests and to explore a number of possible third causes for the deterrent effect we find strong evidence that our deterrence variables are exogenous and no evidence that our deterrence result stems from commonly hypothesized third causes copyright 1994 by mit press

productive efficiency and region based on estimates of cobb douglas production function this study has found that significant spatial variation in labor productivity exists even after adjusting for capital intensity the adjustment for capital intensity reduces the regional variation by 38 to 69 and the ciy size variation by 75 the results reveal a 6 to 8 producitivity advantage for non south census regions relative to the south and productivity increases of 1 5 with each doubling of smsa population nevertheless lower wages in the south and in smaller cities make it and them an attractive location for manufacturing firms the study has also found that the sveikauskas conjecture that labor productivity can be substituted for hicks neutral productivity in an analysis of the latter is false if metropolitan data are used by so doing capital intensity effects and total factor productivity effects are confounded to study spatial variations in total factor productivity productive efficiency it is necessary to control for spatial variations in captial intensity the results of this study indicate that absent better data on capital the approach offered by aberg yields satisfactory results 14 references 2 tables

the injustice of inequality in many countries the operation of legal political and regulatory institutions is subverted by the wealthy and the politically powerful for their own benefit this subversion takes the form of corruption intimidation and other forms of influence we present a model of such institutional subversion focusing specifically on courts and of the effects of inequality in economic and political resources on the magnitude of subversion we then use the model to analyze the consequences of institutional subversion for the law and order environment in the country as well as for capital accumulation and growth we illustrate the model with historical evidence from gilded age united states and the transition economies of the 1990s we also present some cross country evidence consistent with the basic prediction of the model

an empirical characterization of the dynamic effects of police spending on violent and property crime the study estimates the dynamic effects of shocks to police expenditures on measures of violent and property crime rates using annual u s state level data for the period 1960 2015 we employ a structural panel var model and achieve identification by imposing the restriction that police spending responds to structural shocks to crime with at least a lag of 1 year results indicate that a shock to police spending leads to a persistent and significant decreases in violent and property crime rates and b significant and persistent negative impacts on crime rates in periods of high crime but little impacts in periods of low crime variance decompositions show that shocks to police spending account for moderate to large proportions of the variability of u s state level crime rates our findings are robust across separate measures of violent and property crime rates as well as to the inclusion of additional variables to the baseline panel var model jel k42

agglomeration economies in urban manufacturing industries a case of japanese cities abstract the effects of urban agglomeration economies on productivities in two digit manufacturing industries is estimated using the cross section data of japanese cities in 1979 urbanization and localization economies which are major forms of urban agglomeration economies are explicitly separated the estimates of these economies vary considerably among industries light industries receive more productive advantages from urbanization economies than from localization economies but heavy industries experience these economies more from localization economies than from urbanization economies

market wages and youth crime to study the problem of widespread youth crime i analyze a timeallocation model in which consumers face parametric wages and diminishing marginal returns to crime the theory motivates an econometric model that i estimate using data from the national longitudinal survey of youth my estimates suggest that youth behavior is responsive to price incentives and that falling real wages may have been an important determinant of rising youth crime during the 1970s and 1980s moreover wage differentials explain a substantial component of both the racial differential in criminal participation and the age distribution of crime

bias corrected estimation of panel vector autoregressions we derive a bias corrected least squares estimator for panel vector autoregressions with fixed effects the estimator is straightforward to implement and is asymptotically unbiased under asymptotics where the number of time series observations and the number of cross sectional observations grow at the same rate this makes the estimator particularly well suited for most macroeconomic data sets

violent crime does social capital matter this paper examines empirically the effect of some commonly used indicators of social capital such as the prevalence of trust on community members and the participation in voluntary secular and religious organizations on the incidence of violent crimes this is a cross country study whose basic sample consists of 39 developed and developing countries and whose dependent variable is the national intentional homicide rate the paper identifies and deals with three challenges in the empirical estimation of the effect of social capital on the incidence of violent crimes the omittedvariable problem is dealt with by including income inequality and economic growth as additional determinants of a country s violent crime rate the joint endogeneity or reverse causation problem is accounted for by using instrumental variables for social capital in the crime regression the specificity problem that is the potentially opposite effects of group specific and society wide social capital is noted and addressed only indirectly by emphasizing the results applied to the social capital indicators that have application for society as a whole the main result of the paper is that only the component of social capital measured by trust on community members has the effect of reducing the incidence of violent crimes the results regarding measures of other indicators of social capital are rather unclear this may be due to a combination of limited samples inability to fully control for reverse causation and most likely the opposite effects that society wide and group specific social capital may have on violent crime lederman and menendez are economists with the office of the chief economist for latin america and the caribbean of the world bank loayza is a senior economist with the research department of the central bank of chile and he is currently on leave from the development economics research group of the world bank the opinions expressed herein should not be attributed to the world bank the authors are grateful to ed glaeser jeff grogger gale johnson sanjay marwah steve messner nicholas sambanis and an anonymous referee for invaluable comments and suggestions the authors are responsible for any remaining errors

the effects of labor markets and income inequality on crime evidence from panel data we estimate a model of crime using panel data for the u s we focus on the role of labor markets income distribution and demographics on property crime we find strong evidence that favorable labor market conditions have a significant negative effect on property crime we further test this result using sector specific wages and find that crime is most elastic with respect to wages in sectors that use low skilled labor we also find that income inequality has no significant effect on crime and that the proportion of young males in the population has a significant positive effect on crime

income inequality and the taste for revolution abstract although property rights are the cornerstone of market economies throughout history existing claims have been frequently overturned by revolutions one unsettled question is whether income inequality affects the likelihood of revolt this paper takes an approach different from previous studies by introducing data derived from two surveys of revolutionary preferences across a quarter million randomly sampled individuals more people are found to have a preference for revolt when inequality in their nation is high a 1 standard deviation increase in the gini coefficient explains up to 38 percent of the standard deviation in revolutionary support the results hold after controlling for a set of personal characteristics and country and year fixed effects since higher levels of income are found to have a negative impact on the taste for revolt the results suggest that either going for growth or implementing policies that reduce inequality can buy off those individuals with revolutionary preferences

firm location and city size reduced productivity advantages as a factor in the decline of manufacturing in urban areas abstract this paper develops a model of firm location and city size that arrives at theoretical conclusions that differ from those of other authors comparative statics results suggest that changes in national wage levels and productivity levels create no determinate dis advantage for large cities relative to small ones as sites for manufacturing activity increased wage and reduced productivity premiums of large cities however result in unambiguous disadvantages statistical analysis indicates that the productivity advantages of large cities have declined in as many as eight two digit manufacturing industries that provide more than one third of metropolitan production worker employment

do remittances diminish social violence abstractthis paper represents the first attempt to formalise the relationship between remittances and social violence by developing a model that predicts that migrants remittances lead to the reduction of social violence in the recipient economy under the condition that remittances increase the average product of labour using homicide data as an indicator of social violence we tested our model s prediction controlling for the endogeneity problem with appropriate instruments we found that remittances tend to reduce social violence we performed sensitivity analysis on remittances in the empirical specification and found it robust with an unchanged negative sign

poverty and crime in 19th century germany we estimate the impact of poverty on crime in 19th century bavaria germany rainfall is used as an instrumental variable for grain rye prices to address econometric identification problems in the existing literature the rye price was a major determinant of living standards during this period the rye price has a positive effect on property crime a one standard deviation increased property crime by 8 ols estimates are twice as large as instrumental variable estimates highlighting the value of our empirical approach higher rye prices lead to significantly less violent crime though and we argue that higher beer prices caused by the higher rye prices are a likely explanation

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

a race to the bottom in labor standards an empirical investigation abstract one of the concerns over globalization is that as nations compete for investment they relax labor standards to attract firms using spatial estimation on panel data for 135 countries over 17 years we find that the labor standards in one country are positively correlated with those elsewhere i e a cut in labor standards in other countries reduces labor standards in the country in question this interdependence is more evident in labor practices i e enforcement than in labor laws further while we find evidence of competition in both developed and developing countries it is strongest among developing countries with weak standards
