trade policy of a free trade agreement in the presence of foreign lobbying abstract this paper studies the effect of foreign lobbies on trade policy of a country which is a member of a free trade agreement fta it uses a monopolistically competitive political economy model in which the government determines external tariffs endogenously the effect of foreign lobbying under the fta is examined empirically using canadian industry level trade data that allow differentiating of lobby groups by the country of origin the analysis suggests that the presence of foreign lobbying has a significant effect on the domestic trade policy the heterogeneity of foreign lobbies is also important the presence of an organized lobbying group in an fta partner country tends to raise trade barriers while an organized lobbying group of exporters from outside of the fta is associated with less protection

is protection for sale evidence on the grossman helpman theory of endogenous protection grossman and helpman 1994 present a theory of endogenous protection by explicitly modeling government industry interactions for which mere black box models previously existed they obtain a ramsey pricing type solution to the provision of protection which emphasizes the role of inverse import penetration ratios and import elasticities on the lobbying side the model makes predictions about lobbying competition and lobbying spending according to deadweight costs from protection the model not only makes for richer theory in terms of rigor and elegance but its predictions are directly testable whether the grossman helman model stands up to real world data is investigated in this paper predictions from both the protection side and lobbying side are tested using cross sectional u s nontariff barrier data we also compare the second generation grossman helpman model with a more traditional specification our results call for serious consideration of this model in the political economy literature

endogenous free trade agreements and the multilateral trading system i evaluate in this paper the impact of free trade areas ftas on the world trading system i use an oligopolistic political economy model where the external tariffs of fta members as well as the decision to form ftas are endogenously determined in this context i show that ftas are primarily beneficial to the multilateral trading system this conclusion is based first upon the finding that ftas induce their member governments to lower their external tariffs and to do so deeply enough to enhance trade even between fta members and non members while this ensures gains for the latter in general fta members may not gain i show however that governments will endorse only welfare improving arrangements in spite of their political motivations as a result fta members benefit from ratified arrangements as well finally i find that ftas by reducing the role of special interests criteria in governments trade regime decisions also tend to enhance support for further liberalization at the multilateral level

protection versus free trade lobbying competition between domestic and foreign firms this article considers how political interaction between policymakers and domestic and foreign firms endogenously determines tariff rates we show that because of lobbying competition between foreign and domestic firms even a less competitive foreign firm can successfully elicit a tariff reduction under reasonable conditions moreover lobbying competition may also increase the level of aggregate domestic welfare when the market powers of the competing firms are sufficiently alike

the international penetration of ibusiness firms network effects liabilities of outsidership and country clout the burgeoning of ibusiness firms in the modern digital economy challenges the received internationalization theory given that ibusinesses such as social networking sites create value by providing a digital platform for users to interact with one another we employ a user network perspective and externalization logic suggesting that ibusinesses internationalization process depends critically on users collective interactions instead of being solely driven by firms market commitments as noted by the uppsala model however ibusinesses may suffer from liabilities of outsidership due to the boundedness of international network effects drawing on social network theory we demonstrate that such liabilities can be mitigated by first diffusing the ibusiness platform in countries with higher clout our analysis using a unique dataset of mobile ibusiness platforms finds empirical support for the hypotheses we discuss theoretical implications for the network approach of the uppsala model in the digital era

social networks and the dynamics of labour market outcomes evidence from refugees resettled in the u s recent theoretical work suggests that social networks may play an important role in the dynamics of employment and wages across groups of individuals this paper provides empirical evidence of job information flows within social networks and the non linear relationship between social network size and labor market outcomes an extended version of the model developed by calvo armengol and jackson 2004 shows that competition can exist between network members for job referrals and investigates the dynamics between the size of a social network the tenure of network members and labor market outcomes the predictions of the model are tested empirically using a unique data set of refugees resettled in the u s from 2001 2005 the empirical strategy exploits the special institutional environment of refugee resettlement i find that a one standard deviation increase in the number of network members who have arrived in the u s one year ago lowers the probability of employment by 4 9 and the average hourly wage by 70 conversely as predicted by the model more tenured network members improve labor market outcomes for recently arrived refugees

foreign lobbies and us trade policy abstract in popular discussion much has been made of the susceptibility of government policies to lobbying by foreigners the general presumption being that this is harmful to the home economy however in a trade policy context this may not be the case if the policy outcome absent any foreign lobbying is characterized by welfare reducing trade barriers foreign lobbying may reduce such barriers and possibly raise welfare using a new data set on foreign political activity in the united states this paper investigates this question empirically tariffs and nontariff barriers are both found to be negatively related with foreign lobbying activity

weak ties information and influence how workers find jobs in a local russian labor market in 1973 granovetter formulated the strength of weak ties hypothesis swt which became the foundation of a vast sociological literature on social networks in labor markets until now swt has neve

green innovation value chain analysis of pv solar power abstract governments around the world have employed a variety of generous subsidies to help promote and develop clean energy technologies in the hope that they will widely replace dirtier carbon based power sources unfortunately these subsidies have not prevented numerous green technology bankruptcies including the infamous 2011 closure of the california based solar panel producer solyndra and these failures have cost taxpayers and private investors billions in lost capital the green innovation value chain givc provides a possible framework for determining the diffusion prospects of green technologies through environmental and financial comparisons to conventional alternatives across the separate chain links comprised of manufacturers distributors customers government and the environment the givc framework is used here to analyze the photovoltaic solar power chain where financial deficits are found in each link that will need to be reduced or eliminated through technology advancements subsidies or changes in market conditions in order to provide the conditions necessary for the technology to achieve mass market acceptance and positive financial returns

preferential versus multilateral trade liberalization and the role of political economy abstract in this paper we analyze the effect of the freedom to pursue preferential trade liberalization permitted by article xxiv of the gatt on country s incentives to participate in multilateral negotiations and on feasibility of global free trade we present a model in which countries choose whether to participate in preferential or multilateral trade agreements under political pressures from domestic special interest groups we show that heterogeneity in political preferences across countries plays an important role in determining the relative merits of preferential and multilateral approaches to trade liberalization on one hand the opportunity to liberalize preferentially may be necessary to induce countries with strong political motivations to participate in multilateral free trade negotiations on the other hand when countries share similar political preferences multilateral free trade that would have been politically supported otherwise becomes unattainable if countries can pursue preferential liberalization

network competition product quality and market coverage in the presence of network externalities the model identifies the quality of a network product with the number of consumers using it hence the producer cannot unilaterally control the quality of his product using the preference specification of vertical quality differentiation it is shown that the largest network produced will be the most expensive one and used by the richest consumers noncooperative industry structures result in a larger market coverage than cooperative if producers can enter the market freely market coverage with noncompatible networks will be larger however if there is no free entry market coverage is larger with a single industry wide standard copyright 1995 by blackwell publishing ltd

moving to opportunity in boston early results of a randomized mobility experiment this paper examines the short run impacts of a change in residential neighborhood on the well being of low income families using evidence from a program in which eligibility for a housing voucher was determined by random lottery we examine the experiences of households at the boston site of moving to opportunity mto a demonstration program in five cities families in high poverty public housing projects applied to mto and were assigned by lottery to one of three groups experimental offered mobility counseling and a section 8 subsidy valid only in a census tract with a poverty rate of less than 10 percent section 8 comparison offered a geographically unrestricted section 8 subsidy or control offered no new assistance but continued to be eligible for public housing our quantitative analyses of program impacts uses data on 540 families from a baseline survey at program enrollment a follow up survey administered l to 3 5 years after random assignment and state administrative data on earnings and welfare receipt 48 percent of the experimental group and 62 percent of the section 8 comparison group moved through the mto program one to three years after program entry families in both treatment groups were more likely to be residing in neighborhoods with low poverty rates and high education levels than were families in the control group however while members of the experimental group were much more likely to be residing in suburban communities than were those in the section 8 group the lower program take up rate among the experimental group resulted in more families remaining in the most distressed communities households in both treatment groups experienced improvements in multiple measures of well being relative to the control group including increased safety improved health among household heads and fewer behavior problems among boys experimental group children were also less likely to be a victim of a personal crime to be injured or to experience an asthma attack there are no significant impacts of either mto treatment on the employment earnings or welfare receipt of household heads in the first three years after random assignment

cultural transmission and discrimination workers can have good or bad work habits these traits are transmitted from one generation to the next through a learning and imitation process which depends on parents investment in the trait and the social environment where children live if a sufficiently high proportion of employers have taste based prejudices against minority workers we show that their prejudices are always self fulfilled in steady state and minority workers end up having on average worse work habits than majority workers this leads to a ghetto culture affirmative action can improve the welfare of minorities whereas integration can be beneficial to minority workers but detrimental to workers from the majority group

tax policy and urban development evidence from the indiana enterprise zone program abstract this paper analyzes the effect of the indiana enterprise zone ez program on local employment and investment using a panel of local taxing jurisdictions as in other ez programs indiana s incentives favor capital relative to labor but the target of the capital incentive is unusual the stock of inventories using various estimation methods i estimate that zone designation initially reduces the value of depreciable personal property by about 13 percent but also reduces unemployment claims in the zone and surrounding community by 19 percent the value of inventories in indiana zones is 8 percent higher than it would be without the program

social interaction and urban sprawl abstract various authors most notably putnam putnam r d 2000 bowling alone simon and schuster new york have argued that low density living reduces social capital and thus social interaction and this argument has been used to buttress criticisms of urban sprawl if low densities in fact reduce social interaction then an externality arises validating putnam s critique in choosing their own lot sizes consumers would fail to consider the loss of interaction benefits for their neighbors when lot size is increased lot sizes would then be inefficiently large and cities excessively spread out the paper tests the premise of this argument the existence of a positive link between interaction and density using data from the social capital benchmark survey in the empirical work social interaction measures for individual survey respondents are regressed on census tract density and a host of household characteristics using an instrumental variable approach to control for the potential endogeneity of density

density social networks and job search methods theory and application to egypt we first develop a theoretical model in which individuals are embedded within a network of social relationships we show that conditional on being employed the probability to find a job through social networks relative to other search methods increases and is concave with the size of the network the effects are stronger for the uneducated there is however a critical size of the network above which this probability decreases we then test empirically these theoretical findings for egypt using the 1998 labor market survey the empirical evidence supports the predictions of our theoretical model

peer effects and social networks in education this paper studies whether structural properties of friendship networks affect individual outcomes in education we first develop a model that shows that at the nash equilibrium the outcome of each individual embedded in a network is proportional to her katz bonacich centrality measure this measure takes into account both direct and indirect friends of each individual but puts less weight to her distant friends we then bring the model to the data by using a very detailed dataset of adolescent friendship networks we show that after controlling for observable individual characteristics and unobservable network specific factors the individual s position in a network as measured by her katz bonacich centrality is a key determinant of her level of activity a standard deviation increase in the katz bonacich centrality increases the pupil school performance by more than 7 percent of one standard deviation

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

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

a comparison of optimal tariffs and welfare under no lobbying domestic lobbying and domestic foreign lobbying whether and what type of the lobbying induced trade policies can improve the domestic welfare we show that as compared to the case of no lobbying and the case of domestic lobbying the domestic foreign lobbying may achieve the lowest tariff and may also realise the highest welfare for the domestic country our finding provides a theoretical explanation to the prevalent lobbying competition between asian firms and us firms in usa recently we argue that the domestic foreign lobbying may contribute to a freer trade in the domestic country and lobbying competition may be one of the strongest forces pushing for trade liberalisation

rent destruction and the political viability of free trade agreements this paper studies the political viability of free trade agreements ftas the key element of the analysis is the rent destruction that these arrangements induce by eliminating intrabloc trade barriers an fta lowers the incentives of import competing industries to lobby for higher external tariffs thereby inducing a reduction of the rents created in the lobbying process using a conventional competitive model i show that the prospect of rent destruction can critically undermine and in some cases rule out entirely the political viability of welfarereducing ftas this result contrasts sharply with findings from the earlier regionalism literature

do friends and relatives really help in getting a good job informal contacts are extensively used by both firms and workers to find jobs and fill vacancies the common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods this paper explores the empirical evidence for european countries using the european community household panel echp and discovers a large cross country as well as cross industry variation in the wage differentials between jobs found through informal and formal methods across countries and industries wage premiums and wage penalties to finding jobs through personal contacts are equally frequent this paper argues that such variation can be explained by looking at firms recruitment strategies in labour markets where employers invest largely in formal recruitment activities matches created through this channel are likely to be of average better quality than those created through informal networks a simple theoretical model is used to show that employers invest more in recruitment for high productivity jobs and for positions that require considerable training the empirical predictions of the theory are successfully tested using industry level data on recruitment costs

does city structure affect job search and welfare we develop a model in which workers search efficiency is negatively affected by access to jobs workers location in a city is endogenous and reflects a trade off between commuting costs and the surplus associated with search different configurations emerge in equilibrium notably the unemployed workers may reside far away segregated city or close to jobs integrated city we prove that there exists a unique and stable market equilibrium in which both land and labor markets are solved for simultaneously we find that despite inefficient search in the segregated city equilibrium the welfare difference between the two equilibria is not so large due to differences in commuting costs we also show how a social planner can manipulate wages by subsidizing taxing the transport costs and can accordingly restore the efficiency

the effect of the canada us free trade agreement on canadian multilateral trade liberalization in this paper show that the canada us free trade agreement cusfta tariff preferences have triggered a decline in canadian external tariffs explaining a two percentage point reduction in the average tariff between 1989 and 1998 next we found that industries that generate the least export rent to the us firms experienced deeper tariff cuts in canada this result provides evidence of cooperation in trade policies between the us and canada finally we estimate the effect of the cusfta on the intensity of industrial lobbying for trade policy in canada and find no relationship between preferential trade liberalization and lobbying activity resume l effet de l accord de libre echange canada u s sur la liberalisation multilaterale du commerce canadien dans ce texte on montre que les preferences tarifaires de l accord de libre echange canada us alecus ont declenche un declin dans le niveau des droits de douane externes canadiens et expliquent une reduction de deux points de pourcentage dans le tarif moyen entre 1989 et 1998 ensuite on decouvre que les industries qui generent le moins de rentes des exportations vers les etats unis font l experience de reduction de tarifs plus importante au canada ce resultat revele une cooperation dans les politiques commerciales entre canada et etats unis enfin on evalue l effet de l alecus sur l intensite du lobbying industriel a propos de la politique commerciale au canada et on decouvre qu il n existe pas de relation entre la liberation preferentielle du commerce et l intensite de l activite de lobbying

exploring mediators effects of the composition of organizational affiliation on organization survival and mediator performance market mediation literature has been taking primarily a triadic view in studying the role and impact of mediators actors that occupy a middle position on supply and demand conditions in markets mediating organizations facilitate exchange relationships on a continuous basis between multiple networks of interdependent affiliated actors an affiliation structure gives rise to the property of duality whereby the behavior and performance of the affiliates affect the behavior and performance of mediators and vice versa in the context of the banking industry this study examines how the structural properties of the underlying network of affiliated organizations affect the survival of affiliated organizations and the performance of mediating organizations the results show that firms that are affiliated with mediating organizations having high customer set connectedness or with those that are industry specialists increase their chances of survival furthermore mediating organizations having high customer set

do neighborhoods affect hours worked evidence from longitudinal data using a confidential version of the nlsy79 we estimate large effects of neighborhood social characteristics and job proximity on labor market activity a variety of neighborhood social characteristics are associated with less market work social characteristics have nonlinear effects with the greatest impact in the worst neighborhoods social characteristics are also more important for less educated workers exploiting the panel aspects of our data we find that estimates that do not account for neighborhood selection on the basis of time invariant and time varying unobserved individual characteristics substantially overstate the social effects of neighborhoods but understate the effects of job access

informal hiring and income in the labor market this note explores the generalizability of the conventional belief that jobs found through weak social ties and through work related social ties provide higher incomes than jobs found through other means data are analyzed from a sample which is representative of a complete cross section of a large metropolitan labor market the results show that zero order relationships generalize in most instances to broadly defined populations however the effectiveness of weakly tied and work related informal contacts becomes greatly diminished when controls are added for measures of worker productivity characteristics

multilateral tariff cooperation during the formation of free trade areas we consider the impact of the formation of free trade agreements on multilateral tariff cooperation we assume that countries are limited to selfenforcing multilateral arrangements that balance the gains from deviating against the costs of an ensuing trade war we find that the emergence of free trade areas will be accompanied by a temporary retreat from liberal multilateral trade policies as the initial balance supporting multilateral cooperation is upset eventually however as the full impact of the emerging free trade agreement on multilateral trade patterns is felt this initial balance tends to reemerge and liberal multilateral trade policies can be restored

residential mobility and social capital abstract this paper empirically investigates the role of social capital in households residential mobility behavior by considering its spatial dimension this study focuses on a household s social ties with people living nearby which we refer to as its local social capital local social capital may deter residential mobility because the resources stemming from them are location specific and will be less valuable if a household moves we conjecture that a household s possession of local social capital has a negative effect on its residential mobility and this negative effect of local social capital may be stronger on long distance mobility than on short distance mobility our empirical investigation is based on data from the panel study of income dynamics we obtain evidence which is supportive of these conjectures

informal job search and black youth unemployment in this paper i analyze how young black and white unemployed jobseekers use various methods of search and the employment outcomes which result from their use the focus is on distinguishing informal search methods i e friends and relatives or direct application without referral from more formal ones in analyzing racial differences the results show that the two informal methods of search account for about 90 of the difference in employment probabilities between white and black youth this also accounts for 57 71 of the difference in unemployment rates between the two furthermore most of these results reflect differences in the ability of these methods to generate job offers as opposed to differences in search effort or job acceptance rates however our ability to explain these differences through personal family and household characteristics was generally quite limited this abstract was borrowed from another version of this item

managers investors and crises mutual fund strategies in emerging markets the authors address the trading strategies of mutual funds in emerging markets the data set they develop permits analyses of these strategies at the level of individual portfolios a methodologically novel feature of their analysis they disentangle the behavior of fund managers from that of investors for both managers and investors they strongly reject the null hypothesis of no momentum trading funds momentum trading is positive they systematically buy winners and sell losers contemporaneous momentum trading buying current winners and selling current losers is stronger during crises and stronger for fund investors than for fund managers lagged momentum trading buying past winners and selling past losers is stronger during noncrises and stronger for fund managers investors also engage in contagion trading selling assets from one country when asset prices fall in another these findings are based on data about mutual funds that represent only 10 percent of the market capitalization in the countries considered were it a larger share of the market finding counterparties for their trades the investors who buy when they sell and sell when they buy would be difficult and the premise that funds respond to contemporaneous returns rather than causing them would become tenuous

ethnic enclaves and the economic success of immigrants evidence from a natural experiment recent immigrants tend to locate in ethnic enclaves within metropolitan areas the economic consequence of living in such enclaves is still an unresolved issue we use an immigrant policy initiative in sweden when government authorities distributed refugee immigrants across locales in a way that may be considered exogenous this policy initiative provides a unique natural experiment which allows us to estimate the causal effect on labor market outcomes of living in enclaves we find substantive evidence of sorting across locations when sorting is taken into account living in enclaves improves labor market outcomes for instance the earnings gain associated with a standard deviation increase in ethnic concentration is in the order of four to five percent

protection for sale with imperfect rent capturing we extend the protection for sale framework to non tari barriers introducing partial rent capturing leads to a testable specification that bridges the gap between the grossman and helpman 1994 model and its empirical implementation where coverage ratios have been used to measure protection the econometric analysis supports our augmented specification and leads to more realistic estimates for the structural parameters of the model jel classification f13

configuring value for competitive advantage on chains shops and networks building on thompson s 1967 typology of long linked intensive and mediating technologies this paper explores the idea that the value chain the value shop and the value network are three distinct generic value configuration models required to understand and analyze firm level value creation logic across a broad range of industries and firms while the long linked technology delivers value by transforming inputs into products the intensive technology delivers value by resolving unique customer problems and the mediating technology delivers value by enabling direct and indirect exchanges between customers with the identification of alternative value creation technologies value chain analysis is both sharpened and generalized into what we propose as a value configuration analysis approach to the diagnosis of competitive advantage with the long linked technology and the corresponding value chain configuration model as benchmark the paper reviews the distinctive logic and develops models of the value shop and the value network in terms of primary activity categories drivers of cost and value and strategic positioning options 1998 john wiley sons ltd

a residence time model of housing markets abstract this paper estimates a semi markov model of housing markets in which families move from one home to another spend a random amount of time in each home and choose whether to own or to rent at each move limiting conditions of the semi markov process are used to characterize the steady state frequency of owner occupied housing and to simulate the impact of changes in housing tax policy this approach differs markedly from previous studies of housing tax policy which focus on the entire population as opposed to the movers and ignore the effect of household residence times see king 1980 rosen 1979 white and white 1977 or laidler 1969 residence times further influence the analysis by affecting the relative cost of owning to renting in the tenure choice model homeowners pay legal and realtor fees at the time they move out of their homes which renters do not have to pay the discounted value of these fees declines with length of stay and provides a structural explanation of why families with longer residence times have a greater propensity to own results from the empirical analysis suggest that the semi markov model closely predicts conditions in the united states and provide important insights into the effects of housing tax policy residence times are also found to influence household tenure choice through their impact on the discounted legal and realtor fees paid by homeowners

strong and weak ties in employment and crime this paper analyzes the interplay between social structure and information exchange in two competing activities crime and labor we consider a dynamic model in which individuals belong to mutually exclusive two person groups referred to as dyads there are multiple equilibria if jobs are badly paid and or crime is profitable unemployment benefits have to be low enough to prevent workers for staying too long in the unemployment status because they are vulnerable to crime activities if instead jobs are well paid and or crime is not profitable unemployment benefits have to be high enough to induce workers to stay unemployed rather to commit crime because they are less vulnerable to crime activities also in segregated neighborhoods characterized by high interactions between peers a policy only based on punishment and arrest will not be efficient in reducing crime it has to be accompanied by other types of policies that take into account social interactions

spatial mismatch in search equilibrium we construct a search equilibrium model for a city with central and suburban labor markets that is consistent with the set of empirical regularities commonly associated with the spatial mismatch hypothesis a higher rate of unemployment for central city residents than suburban residents a higher job vacancy rate for suburban firms and reverse commuting and higher suburban wages the effectiveness and welfare implications of public policy programs that might be used to remedy the underlying mismatch are examined

assessing the incidence and efficiency of a prominent place based policy abstract this paper empirically assesses the incidence and efficiency of round i of the federal urban empowerment zone ez program using confidential microdata from the decennial census and the longitudinal business database using rejected and future applicants to the ez program as controls we find that ez designation substantially increased employment in zone neighborhoods and generated wage increases for local workers without corresponding increases in population or the local cost of living the results suggest the efficiency costs of first round ezs were relatively modest jel h26 h77 j31 r23 r58

on the optimal structure of government subsidies for enterprise zones and other locational development programs abstract government locational development programs often reward businesses for decisions they would have made or that are going to be quickly reversed this paper presents a model to determine the amount and structure of government locational subsidies that minimize this problem we model the firm s decision to switch locations as an option whose value depends on stochastic operating costs the costs to switch locations and subsidies offered by the government the government maximizes the expected benefit from the operation of the firm within its preferred location by choosing a subsidy package that explicitly and endogenously recognizes the firm s switching option

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

spatial versus social mismatch the aim of this paper is to provide a new mechanism based on social interactions explaining why distance to jobs can have a negative impact on workers labor market outcomes especially ethnic minorities building on granovetter s idea that weak ties are superior to strong ties for providing support in getting a job we develop a model in which workers who live far away from jobs choose to have less connections to weak ties because of the lack of good public transportation in the us it is costly both in terms of time and money to commute to business centers to meet other types of people who can provide other source of information about jobs if distant minority workers mainly rely on their strong ties who are more likely to be unemployed there is then little chance for them of escaping unemployment it is therefore the separation in both the social and physical space that prevents ethnic minorities from finding a job

space and unemployment the labor market effects of spatial mismatch the aim of this article is to analyze the effects of housing discrimination on the wages and unemployment rates of black workers the unemployment effect is first analyzed using a simple minimum wage model an efficiency wage model is then adopted in order to endogenize both unemployment and wages under both models suburban housing discrimination leads to a higher unemployment rate for blacks in the central city than in the suburbs under the efficiency wage model black wages are also lower in the center the analysis thus generates a link between unemployment and a seemingly unrelated phenomenon racial discrimination in the housing market

cash in your face the cost of racial and ethnic discrimination in housing abstract according to recent evidence racial and ethnic discrimination in housing continues to be widespread this paper estimates the cost this discrimination imposes on black and hispanic households building on the work of 4 the paper develops a housing search model and measures the cost of discrimination by its impact on the gain a household can achieve through housing search the cost of discrimination is then calculated for a representative sample of households the punchline black and hispanic households pay a discrimination tax of almost 4 000 on average every time they search for a house to buy

are targeted wage subsidies harmful evidence from a wage voucher experiment this paper presents the results of a controlled experiment designed to test the effectiveness of a targeted wage subsidy program such programs are intended to increase the employment of target group workers by offering employers reimbursement for part of those workers wages in the dayton ohio experiment however job seekers given experimental vouchers identifying them to employers as eligible for a generous wage subsidy were significantly less likely to find employment than were job seekers without vouchers the author speculates that the vouchers had a stigmatizing effect and provided a screening device with which employers discriminated against economically disadvantaged workers

search method use by unemployed youth this article presents a search model which shows that search method choices should be related to their costs and expected productivities as well as to nonwage income and wage offer distributions the empirical evidence then shows that the most frequently used search methods i e friends and relatives and direct applications without referral are also the most productive in generating offers and acceptances the number of methods used is affected by factors that presumably reflect opportunities as well as income sources and needs specific methods are chosen in a manner that generates positive average effects on outcomes for those using them

the mechanisms of spatial mismatch the spatial mismatch hypothesis smh argues that low skilled minorities residing in us inner cities experience poor labour market outcomes because they are disconnected from suburban job opportunities this assumption gave rise to an abundant empirical literature which is rather supportive of the smh surprisingly it is only recently that theoretical models have emerged which probably explains why the mechanisms of spatial mismatch have long remained unclear and not properly tested this article presents relevant facts reviews the theoretical models of spatial mismatch confronts their predictions with available empirical results and indicates which mechanisms deserve further empirical tests

north south negotiations on emission reductions a bargaining approach this article models north south negotiations on emission reductions where the north provides side payments in exchange for the south s adoption of a more stringent emission standard we find that depending on where firms compete strong asymmetry among regions the two regions different valuations of side payments and climate change damage can produce self enforcing cooperative agreements moreover the south s optimal standard choice can be one of two polar cases i e either the cleanest or the dirtiest irrespective of the continuum of standards available the results above can also hold true when both parties bargain over the south s emission tax

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

anti lobbying gains from international agreements abstract i argue that an important potential benefit of international agreements is to reduce wasteful rent seeking activities by domestic and foreign special interest groups through a reduction in policy discretion the presence of foreign lobbying generates a novel type of international externality by inviting wasteful rent seeking by foreign lobbies the presence of policy discretion itself generates a negative international externality i examine the potential anti lobbying effects of three salient types of international rules exact policy commitments policy bounds and non discrimination rules unlike exact policy commitments which remove policy discretion and hence shut down ex post lobbying policy bounds may invite ex post lobbying and hence may forego part or all of the potential anti lobbying gains i also find that policy bounds may lead to mixed strategy equilibria of the rent seeking game a non discrimination rule can reduce rent seeking by foreign lobbies by injecting a free rider problem in the strategic interaction between these lobbies and under some conditions can achieve all the potential anti foreign lobbying gains

a strategic and welfare theoretic analysis of free trade areas abstract we construct a three country model to determine how the formation of free trade areas ftas affects optimal tariffs and welfare we find that at constant rest of the world row tariffs the adoption of internal free trade induces union members to reduce their external tariffs below the kemp wan j int econom 6 1976 95 97 level and causes row s terms of trade to improve and its welfare to rise when row also behaves optimally its policy response to the formation of the fta is to raise tariffs generally fta members prefer to liberalize internal trade partially and find regional integration appealing only if their collective size is sufficiently large we also demonstrate how ftas may undermine the attainment of global free trade

trade diversion and declining tariffs evidence from mercosur abstract this paper empirically examines the alternative posed by richardson j intern econ 34 1993 39 to the traditional view that trade integration may exacerbate inefficiencies richardson s hypothesis boldly predicts that trade diversion and trade creation may actually cause tariffs to decline the hypothesis is fundamentally attributable to the presence of a political component in the governments objective functions a cross sectionally rich data set on trade and tariffs from the mercosur pact countries primarily argentina is used the evidence yields surprising conclusions about the validity of endogenous tariff determination in models of trade integration

the impact of product attributes and emerging technologies on firms international configuration international business literature has largely explained the international dispersion of firms activities as a choice based on trade offs between cost minimisation knowledge seeking managing transaction costs and maintaining control by incorporating insights from operations management we propose a framework that explicitly takes into account products physical and knowledge attributes that constrain the viable international configuration options available to firms linking the characteristics of a product to the scope for horizontal and vertical decoupling in a value network allows us to re frame recent discussions in the literature about fragmentation of activities vs tasks and to develop an overall picture of the way industry specific peculiarities characterise and also constrain viable international configurations we show how our framework can be used to interpret data on the scope for decoupling and dispersion collected from industry experts and elucidate the relationships between configuration options and measures of product characteristics we then utilise this framework to predict how emerging technologies will reshape the international configuration options available to firms

neighborhood effects on crime for female and male youth evidence from a randomized housing voucher experiment the moving to opportunity mto demonstration assigned housing vouchers via random lottery to public housing residents in five cities we use the exogenous variation in residential locations generated by mto to estimate neighborhood effects on youth crime and delinquency the offer to relocate to lower poverty areas reduces arrests among female youth for violent and property crimes relative to a control group for males the offer to relocate reduces arrests for violent crime at least in the short run but increases problem behaviors and property crime arrests the gender difference in treatment effects seems to reflect differences in how male and female youths from disadvantaged backgrounds adapt and respond to similar new neighborhood environments

racial segregation and the black white test score gap abstract racial segregation is often blamed for some of the achievement gap between blacks and whites we study the effects of school and neighborhood segregation on the relative sat scores of black students across different metropolitan areas using large microdata samples for the 1998 2001 test cohorts our models include detailed controls for the family background of individual test takers school level controls for selective participation in the test and city level controls for racial composition income and region we find robust evidence that the black white test score gap is higher in more segregated cities holding constant family background and other factors a shift from a highly segregated city to a nearly integrated city closes about one quarter of the raw black white gap in sat scores specifications that distinguish between school and neighborhood segregation suggest that neighborhood segregation has a consistently negative impact while school segregation has no independent effect though we cannot reject equality of the two effects additional tests indicate that much of the effect of neighborhood segregation operates through neighbors incomes not through race per se data on enrollment in honors courses suggest that within school segregation increases when schools are more highly integrated potentially offsetting the benefits of school desegregation and accounting for our findings

location and education in south african cities under and after apartheid we model a south african city during apartheid in which both schooling and mobility are restricted on the basis of race and after apartheid in which no restrictions are imposed we first show that the inequality between blacks and whites decreases when apartheid laws are removed indeed blacks are better off because of human capital externalities due to the possibility of mixing with white students whereas whites are worse off due to negative human capital externalities and intensified land market competition after apartheid we also show that reducing the commuting costs of black children always increases the utility of black families and may even increase that of whites

measuring racial discrimination with fair housing audits caught in the act a survey technique called a fair housing audit provides a direct measure of racial discrimination in housing this paper examines the econometric issues raised by audit data measures the discrimination uncovered by a 1981 boston study and tests hypotheses about the causes of discrimination the estimated level of discrimination is high black housing seekers are told about 30 percent fewer available housing units than are whites the hypothesis tests indicate that the primary cause of this discrimination is that housing agents illegally promote their economic interests by catering to the racial prejudice of their current or potential white customers
