the expansion of modern agriculture and global biodiversity decline an integrated assessment the world is banking on a major increase in food production if the dietary needs and food preferences of an increasing and increasingly rich population are to be met this requires the further expansion of modern agriculture but modern agriculture rests on a small number of highly productive crops and its expansion has led to a significant loss of global biodiversity ecologists have shown that biodiversity loss results in lower plant productivity while agricultural economists have linked biodiversity loss on farms with increasing variability of crop yields and sometimes lower mean yields in this paper we consider the macro economic consequences of the continued expansion of particular forms of intensive modern agriculture with a focus on how the loss of biodiversity affects food production we employ a quantitative structurally estimated model of the global economy which jointly determines economic growth population and food demand agricultural innovations and land conversion we show that even small effects of agricultural expansion on productivity via biodiversity loss might be sufficient to warrant a moratorium on further land conversion

the commuting time paradox abstract we examine the conditions for the commuting time paradox which states that the average commuting time does not vary between different periods we develop therefore an equilibrium job search model with endogenously chosen commuting costs presuming wage bargaining between workers and firms the optimally chosen maximum commuting costs jointly maximise the worker s and firm s payoffs we demonstrate that when productivity levels increase over time average commuting costs and average wages both increase which affects the optimally chosen commuting time we establish the conditions under which the paradox holds

oppositional identities and employment for ethnic minorities evidence from england where a community or group is socially excluded from a dominant group some individuals of that group may identify with the dominant culture and others may reject that culture the aim of this article is to investigate this issue by empirically analysing the potential trade off for ethnic minorities between sticking to their own roots and labour market success we find that the social environment of individuals and attachments to culture of origin has a strong association with identity choice our results also suggest that those non whites who have preferences that accord with being oppositional do experience an employment penalty

using local labor market data to re examine the employment effects of the minimum wage using quarterly census data for 1996 2000 the author evaluates how minimum wages affected teenage employment at the county level an analysis that includes all counties yields small and statistically insignificant effects consistent with previous research using state panels however in counties where the minimum wage was likely binding above the market clearing wage for teens the negative impact on employment was considerably larger the effect was strongest in small counties was restricted to transitory jobs and new hires and apparently was not experienced by young adults ages 19 22 the small employment effects found in much of the literature the author argues at least partly reflect the estimates inclusion of local labor markets where the minimum wage is not binding by averaging the effects across all areas with no disaggregation based on where the minimum wage is binding and where it is not these studies overlook important regional variation

are ghettos good or bad spatial separation of racial and ethnic groups may theoretically have positive or negative effects on the economic performance of those groups we examine the effects of segregation on outcomes for blacks in schooling employment and single parenthood we find that blacks in more segregated areas have significantly worse outcomes than blacks in less segregated areas we control for the endogeneity of location choice using instruments based on political factors topographical features and residence before adulthood a one standard deviation decrease in segregation would eliminate one third of the black white differences in most of our outcomes

black residential centralization and the spatial mismatch hypothesis abstract black residential centralization is found to be an important determinant of black employment status when estimated across metropolitan areas mas to avoid neighborhood selection the effects are greatest in large mas for the young and elderly and for individuals with less than a college education instrumental variable iv estimates support ordinary least squares ols results black residential centralization can account for 48 62 of the black white employment differential among 18 30 year olds living in large mas when estimated together black residential centralization job centralization and segregation all have large effects but the effects of black centralization and job centralization are considerably larger

ethnic unemployment rates and frictional markets the unemployment rate in france is roughly 6 percentage points higher for african immigrants than for natives in the us the unemployment rate is approximately 9 percentage points higher for blacks than for whites commute time data indicates that minorities face longer commute times to work potentially reflecting more difficult access to jobs in this paper we investigate the impact of spatial mismatch on the unemployment rate of ethnic groups using the matching model proposed by rupert and wasmer 2012 we find that spatial factors explain 1 1 5 percentage points of the unemployment rate gap in both france and the us amounting to 17 25 of the relative gap in france and about 10 17 5 in the us among these factors differences in commuting distance play the most important role in france though longer commuting distances may be mitigated by higher mobility in the housing market for african workers overall we still conclude that labor market factors remain the main explanation for the higher unemployment rate of africans

search sorting and urban agglomeration studies have suggested that urban agglomeration enhances productivity by facilitating the firm worker matching process this article develops a model that formalizes this notion and demonstrates that when firm capital and worker skill are complementary in production urban agglomeration will tend to generate more efficient yet segregated matches as a result not only will local market size be positively associated with average productivity it will also generate greater between skill group wage inequality and a higher expected return to skill acquisition recent data from the counties and metropolitan areas of the united states is consistent with each of these implications

where youth live economic effects of urban space on employment prospects this paper synthesises a series of empirical analyses investigating the role of urban space in affecting minority employment outcomes it broadens the focus beyond transport and the friction of sp

job search and unemployment duration implications for the spatial mismatch hypothesis abstract this paper analyzes the relationship between unemployment duration and the spatial distribution of employment it builds on the spatial mismatch literature by analyzing the role of access in a job search framework a unique measure of access is created using municipal level employment growth and a matrix of commuting times for the pittsburgh metropolitan area individuals with more access to employment are found to have shorter unemployment spells the effect of access on unemployment duration is found to be sensitive to the specification of access

city structure and the location of young college graduates abstract this paper investigates an equilibrium search model with on the job search endogenous wage formation and land allocation search frictions are increasing with the distance to a city s central business district we find a positive relationship between wage and distance to jobs this can be explained by the fact that the number of acceptable outside offers decreases with the wage we are able to relate our results to some empirically relevant aspects on gentrification

neighborhood crime and young males job opportunity abstract a puzzling aspect of america s crime problem is the concentration of crime in poor inner city neighborhoods the economic model of crime suggests that this concentration may be caused by a dearth of legitimate earnings opportunities for young males living in these neighborhoods while studies on spatial mismatch in the low skilled labor market have documented the relatively poor job opportunity possessed by youth in these neighborhoods there exists no evidence on the role job opportunity plays in explaining the dramatic spatial variation in crime within urban areas using a unique panel of neighborhood crime and employment data for atlanta i estimate models that control for time and fixed effects as well as the possible endogeneity of job opportunity the results suggest that young males job opportunity plays a key role in resolving the enigma surrounding the high variation in crime across urban neighborhoods

an empirical analysis of competitive nonlinear pricing abstract we estimate a model of competitive nonlinear pricing with multidimensional preference heterogeneity using individual level data on advertisements bought by local businesses e g doctors electricians from two yellow page directories in one u s city market variation in individual choices and payments allows us to identify the joint density of preferences marginal costs of publishing and common utility parameters our estimates suggest substantial welfare loss due to asymmetric information comparing duopoly outcomes with counterfactual monopoly outcomes we find that with less competition i producer surplus increases substantially ii more low type consumers are excluded iii product variety increases but benefits accrue only to the high type consumers iv total consumer surplus decreases v but its distribution across consumers does not change

unemployment and urban labour markets two quite distinct views on how metropolitan labour markets work have co existed for over three decades both claim empirical support and after a brief period of confrontation they continue to co exist today giving quite conflicting signals to policy makers according to the first model the urban labour market consists of a number of spatially defined sub markets so that local unemployment exists primarily because of deficiencies in highly localised demand for labour by this argument unemployment rates remain high in the absence of a renewed supply of appropriate jobs within short commuting distances of the jobless the solution according to this model is to attract private and public sector production into such areas in contrast a second model views the city as a single market in which transactions between labour and capital take place regardless of the location of residence and employment sites according to this perspective the spatial incidence of unemployment simply reflects the residential

a nonparametric test for comparing valuation distributions in first price auctions this article proposes a nonparametric test for comparing valuation distributions in first price auctions our test is motivated by the fact that two valuation distributions are the same if and only if their integrated quantile functions are the same our method avoids estimating unobserved valuations and does not require smooth estimation of bid density we show that our test is consistent against all fixed alternatives and has nontrivial power against root n local alternatives monte carlo experiments show that our test performs well in finite samples we implement our method on data from u s forest service timber auctions

ethnic enclaves and immigrant labor market outcomes quasi experimental evidence i examine the effects of the ethnic enclave size on labor market outcomes of immigrants i account for ability sorting into enclaves by exploiting a danish spatial dispersal policy under which refugees were randomly dispersed across locations first i find strong evidence that refugees with unfavorable unobserved characteristics self select into ethnic enclaves second a relative standard deviation increase in the ethnic enclave size increases annual earnings by 18 on average irrespective of skill level third further findings are consistent with the explanation that ethnic networks disseminate job information which increases the job worker match quality and thereby the hourly wage rate

changes in labor force status among the unemployed i argue against the popular view that young black men experience more joblessness than their white counterparts because they have priced themselves out of the labor market the seemingly excessive reservation wages of jobless young black men what they

the price of virtue this article offers new evidence on the determinants of u s unwed birth rates from 1981 to 1990 we show that illegitimacy rates are positively and significantly correlated with payments under the aid to families with dependent children program over a period in which real afdc payments declined we attribute this result to a decline in the social sanctions for illegitimacy because social sanctions declined so did the cost of deviance as well as the price for which unwed women sold their virtue

spatial mismatch in the labor market and racial differences in neighborhood crime abstract results from estimating fixed effects models of neighborhood crime show that an important cause of higher crime in black neighborhoods is the poor job accessibility of black youth a key result is that access explains 21 of the difference in property crime between black and white neighborhoods

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

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

the impact of public transport on us metropolitan wage inequality this article presents a wage inequality analysis for 158 large us metropolitan statistical areas msas the analysis is concerned with whether public transport has a detectable influence on 1990 levels of wage equality because public transport systems are generally designed to link residences with employment locations higher levels of service provision all other factors being equal should be associated with higher employment rates and more uniform distributions of earnings few analyses however have attempted to evaluate public policies that affect wage distributions the results of this research provide a macroscopic view of the effectiveness of urban transport investments with respect to urban wage inequality

search theory and the wage curve abstract this paper investigates whether a search theoretic model can explain the wage curve that is a negative relationship between regional wages and regional unemployment rates even if the workers are mobile between regions we show that a simple search model if combined with regional variations in productivity and with a monocentric city structure produces the wage curve

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

job accessibility and female employment probability the cases of barcelona and madrid the objective of this paper is to estimate the impact of residential job accessibility on female employment probability in the metropolitan areas of barcelona and madrid following a spatial mismatch framework a female employment probability equation is estimated which includes variables controlling for personal characteristics residential segregation and employment potential by public transport network data used come from the micro census 2001 of ine the national institute of statistics the research focuses on the treatment of endogeneity problems and the measurement of accessibility variables the results show that low job accessibility in public transport negatively affects employment probability the intensity of this effect tends to decrease with individual s educational attainment a higher degree of residential segregation also reduces job probability in a significant way

car ownership employment and earnings abstract we assess whether the positive relationship between car ownership and employment outcomes reflects a causal effect of auto ownership we match state level data on car insurance premiums and gas taxes to a microdata sample containing information on car ownership and employment outcomes in ols regressions that control for observable covariates we find large differences in employment rates weekly hours worked and hourly earnings between those with and without cars instrumenting for car ownership with insurance and gas taxes yields estimates of the employment and hours effects that are quite close to the ols estimates concerning wages instrumenting eliminates the positive impact of auto ownership

systematic and random search a synthesis this paper synthesizes two models of search in the labor market systematic and random we construct and test a theoretical model in which the searcher is endowed with information on some possibly zero or all individual firms in the labor market as well as the overall wage offer distribution we test the model using a special wave of the 1976 current population survey the major theoretical results of our model are as follows searchers with lower stocks of knowledge about individual firms higher discount rates or having lower coverage by unemployment insurance are more likely to engage in random search activities

the displacement effect of reemployment bonus programs we develop a partial equilibrium matching model of the labor market in order to examine whether adoption of a reemployment bonus would displace workers not offered the bonus we examine the displacement effect for a unemployment insurance ui eligible workers who are offered but do not find a job in time to qualify for a bonus and b ui ineligible workers who are never offered a bonus the model predicts minimal displacement of the former group but for the latter group the model predicts an increase in unemployment duration of 2 4 week and an increase in unemployment of up to 2 per thousand

job search in thick markets abstract i analyze empirically the effects of urban and industrial agglomeration on both search behavior and the efficiency of matching the analysis is based on a unique panel data set from the italian labor force survey micro data covering 520 randomly drawn local labor market areas 66 of the total over the four quarters of 2002 i compute transition probabilities from non employment to employment by jointly estimating the probability of searching and the probability of finding a job conditional on having searched i then test whether these are affected by market size industrial variety and or industry specialization the main results indicate that market size and industry specialization raise job seekers chances of finding employment conditional on having searched while industrial variety is not significantly different from zero finally the effect of agglomeration on non employed individuals search behavior cannot be significantly distinguished from zero

willingness to work among youth i argue against the popular view that young black men experience more joblessness than their white counterparts because they have priced themselves out of the labor market the seemingly excessive reservation wages of jobless young black men what they

spatial mismatch and costly suburban commutes can commuting subsidies help proponents of the spatial mismatch hypothesis argue that job decentralisation harms low income residents of central cities because of barriers that limit their access to suburban labour markets such barriers can take the form of housing discrimination exclusionary zoning or long and difficult commutes this paper uses an urban equilibrium model of spatial mismatch to analyse the impact of commuting subsidies on the welfare of low income central city households with restricted mobility specifically it seeks to determine how effective such subsidies are at reducing the welfare impact of spatial mismatch while subsidised outward commuting is found to raise the welfare of the low income households the welfare gains are only a small portion of the welfare loss due to spatial mismatch

racial discrimination and redlining in cities we propose a model where employers have two types of prejudices racial and spatial discriminations because of the rst one black workers have less chance than white workers to nd a job because of the second one workers living closer to the city center have less chances than suburban workers to nd a job in this context we show that depending on the importance of access costs to employment centers two urban equilibria may emerge in equilibrium 1 the access cost for blacks is quite large black and white workers are totally separated while in equilibrium 2 the access cost for blacks is relatively small workers are separated by their employment status the unemployed versus the employed we then study the labor market equilibrium and its interactions with the land market we show in particular that both race and space matter to explain high unemployment rates among blacks

city structure search and workers job acceptance behavior abstract this paper develops a stochastic search model having a monocentric city structure and investigates how city structure affects workers job acceptance behavior and a labor market in the model workers reside in a city and commute to the central business district cbd to work when employed and to be interviewed when unemployed when a job searcher contacts a firm having a vacant job he she observes the level of training costs necessary for employment and decides whether to accept the job it is shown that there exists a unique market equilibrium in which the employed live close to the cbd and the unemployed reside far away from the cbd analysis shows that 1 improvement of commuting technology induces job searchers to accept more costly jobs and lowers the unemployment rate in the city 2 growth of the city makes job searchers less tolerant of training and raises the unemployment rate and 3 as job searchers search more intensively they become choosier if commuting costs are sufficiently small efficiency properties of the equilibrium are also explored

engineering an incentive to search for work a comparison groups approach social comparisons are important in the employment sphere a culture of unemployment may evolve and prevail because it is optimal for an individual to remain unemployed when other unemployed individuals constitute his main reference group we advance the idea that by making the receipt of unemployment benefits conditional on engagement in an incentive enhancing activity for example work under state sponsored employment schemes or participation in work site based training programs a government can engineer a revision of the reference groups of an unemployed individual in order to induce him to seek work

entitled to work urban property rights and labor supply in peru this brief summarizes the results of a gender impact evaluation study entitled entitled to work urban property rights and labor supply in peru new legal rights were issued in 1996 project teams providing titling service through 2003 in peru the study observed that between 1996 and 2003 the peruvian government issued property titles to over 1 2 million urban households the largest titling program targeted at urban squatters in the developing world this paper examines the labor market effects of increases in tenure security resulting from the program pre program squatters in program neighborhoods were significantly more likely to report improved tenure security by 60 percent similarly program participants were 18 8 percentage points less likely to report a high likelihood of eviction or invasion and 18 8 percentage points more likely to report that their dwelling was currently very secure from eviction or invasion the likelihood of working inside the home significantly falls by 11 6 percentage points for the average squatter family with two program periods

job access employment and earnings outcomes for welfare leavers in a us urban labour market this article examines the effect of job access on employment outcomes for welfare recipients in cleveland ohio leaving assistance during 1998 2000 a rich longitudinal dataset is employed combining administrative and survey data with multiple measures of access to and competition for jobs the focus is on both a population and a range of measures of employment outcomes not previously studied in this context empirical ambiguity in the existing literature has resulted from the difficulty of modelling causality when employment and residential location are jointly determined in this study labour market outcomes are related to the residential locations of welfare leavers prior to employment thus overcoming much potential endogeneity virtually no evidence is found that job access influences labour market outcomes for this population

job contact networks abstract many workers hear about or obtain their jobs through friends and relatives the aim of this paper is twofold first we relate both individual and aggregate labor market outcomes to the network structure of personal contacts second we study strategic network formation to this purpose we develop a model specifying at the individual level both the decision to form contacts with other agents and the process by which information about jobs is obtained and transmitted we show that equilibrium networks always exist and that only moderate levels of network asymmetry can be sustained at equilibrium also we establish a general non monotonicity result on information flow and unemployment with respect to network size in symmetric networks

the role of spatial and skill mismatches explaining long term unemployment in paris in the paris region one can observe simultaneously the coexistence of a large and dynamic job pool with long lasting periods of unemployment this paradox reveals the importance of skill and spati

the economic costs of conserving genetic resources at the cgiar centres abstract the 11 genebanks of the consultative group on international agriculture cgiar have grown considerably in size over the past few decades currently holding about 666 000 accessions of germplasm conserving germplasm is a very long run if not in perpetuity proposition the mismatch between the mainly annual funding support for this conservation effort and its very long term nature and intent is a serious concern using the results of five cgiar genebank case studies accounting for 87 of the total cgiar genebank holdings we estimate the size of an endowment or trust fund that would be required to assure a funding stream to conserve this genetic material for future generations the annual cost in year 2000 us of conserving and distributing the genetic material presently held in all 11 cgiar genebanks is estimated to be 5 7 million us mus which could be maintained for all future generations by setting aside a fund of 149 mus invested at a real rate of interest of 4 per annum this would be sufficient to underwrite the costs for the cgiar s current conservation activities in perpetuity estimated to be 61 mus as well as the cost of maintaining the distribution activities 88 mus that provide germplasm to breeders scientists farmers and others world wide

car ownership and the labor market of ethnic minorities we show how initial wealth differences between low skilled minorities and white workers can generate differences in their labor market outcomes this even occurs in the absence of a taste for discrimination against ethnic minorities or exogenous differences in distance to jobs because of the initial wealth difference minorities cannot afford to buy a car while whites can car ownership allows whites to reach more jobs per unit of time which gives them a better bargaining position in the labor market as a result in equilibrium ethnic minorities end up with both higher unemployment rates and lower wages than whites furthermore we also show that it takes more time for minorities to reach their jobs even though they travel less miles when employed those predictions are consistent with the data better access to capital markets or better public transportation will reduce the differences in labor market outcomes

spatial mismatch search effort and urban spatial structure abstract the aim of this paper is to provide a new mechanism for the spatial mismatch hypothesis spatial mismatch can here be the result of optimizing behavior on the part of the labor market participants in particular the unemployed can choose low amounts of search and long term unemployment if they reside far away from jobs they choose voluntary not to relocate close to jobs because the short run gains low land rent and large housing consumption are big enough compared to the long run gains of residing near jobs higher probability of finding a job

an empirical investigation of the returns to job search the assumption of diminishing returns to job search plays a crucial role in the search model presented recently in this review by john seater this assumption is justified by noting that spatial aspects of the search process cause diminishing returns since travel time required to search firms in a circular area increases faster than the area to be searched besides being an important property of a class of theoretical models returns to search may partly explain the paradox of an approximately forty hour workweek contrasted with a seven hour search week see john barron and wesley mellow p 396 the interaction of diminishing returns to and positive costs of search may result in an optimal allocation of search time of only a few hours per week in this paper i examine whether the assumption of diminishing returns to job search can be supported by the data following seater the returns to search are measured by the number of firms contacted and the focus is on the ability of unemployed individuals to translate search time into employee contracts returns to search are evaluated by noting whether the production process exhibits diminishing returns with respect to the input variable

spatial mismatch transport mode and search decisions in england abstract we develop a theoretical model in which whites mainly use private vehicles to commute whereas nonwhites use public transportation we show that for both whites and nonwhites higher time distance to jobs leads to lower search effort because of different transport modes we also show that at exactly the same time distance to jobs white unemployed workers search more intensively than nonwhites because it is less costly for them to gather information about jobs we then test this model using english sub regional data we find that for each race indeed living in areas where distance to jobs is higher yields the unemployed to search less than in areas with better job access we also find that having access to a car increases search intensity for both whites and nonwhites finally closing the racial gap in car access and distance to jobs would considerably narrow the difference in search intensities between whites and nonwhites

job relocation and the racial gap in unemployment in detroit and chicago 1980 to 1990 the spatial mismatch hypothesis argues that residential segregation and job decentralization combine to adversely affect the employment opportunities of minorities while employment is increasingly located outside of central cities residential segregation prevents minorities from moving closer to suburban jobs although this hypothesis has intuitive appeal there is little consensus regarding its empirical validity this study 1 constructs detailed geographic measures of changes in employment opportunities 2 estimates a fixed effects model of changes in the unemployment rate over time and 3 accounts for spatial correlation in the error term neighborhood level employment data from 1980 and 1990 are used to measure changes in the distance to jobs from census tracts in the detroit and chicago metropolitan areas in both cities the decentralization of employment and the loss of manufacturing jobs resulted in substantial changes in the spatial distribution of employment the empirical results indicate that a decline in the spatial proximity to employment is associated with an increase in the unemployment rate for blacks

location search costs and youth unemployment experimental evidence from transport subsidies do high search costs affect the labour market outcomes of jobseekers living far away from jobs i randomly assign transport subsidies to unemployed youth in urban ethiopia treated respondents increase job search intensity and are more likely to find good permanent jobs subsidies also induce a short term reduction in temporary work i use a high frequency phone call survey to track the trajectory of search behaviour over time to show that the subsidies significantly increased job search intensity and the use of formal search methods the evidence suggests that cash constraints cause young people to give up looking for good jobs too early

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

the spatial mismatch hypothesis what has the evidence shown this paper reviews 20 years worth of empirical evidence on the spatial mismatch hypothesis after briefly surveying the relevant models from urban and labour economics and recent trends in employment and population suburbanisation the empirical evidence on spatial effects is examined this literature includes evidence on the effects of residential segregation residential suburbanisation and employment suburbanisation and direct measures of access such as travel times the most recent evidence suggests that spatial mismatch is relevant for explaining black white employment differences though the magnitudes of these effects remain unclear

intra metropolitan shifts in labor demand and the adjustment of local markets abstract i offer new evidence on the adjustment of local labor markets to geographic shifts in labor demand within us metropolitan areas using a unique data set in which metropolitan subregions are geographically matched across the 1970 1980 and 1980 1990 decades the evidence uncovered paints the following picture workers especially those with less education make incomplete adjustments within metropolitan areas in response to intra metropolitan demand shifts although blacks may not make especially limited adjustments they have disproportionately suffered deleterious effects from job movements because the demand shifts have tended to be away from their places of residence

commuting in search of jobs and residences abstract this paper introduces a model which includes residential job moving and commuting behavior when labor and housing markets are characterized by market imperfections imperfect information and moving costs we examine the consequences of these market imperfections on commuting behavior an empirical analysis of commuting behavior indicates that workers commute less if they receive more job offers

farmers subjective valuation of subsistence crops the case of traditional maize in mexico shadow prices guide farmers resource allocations but for subsistence farmers growing traditional crops shadow prices may bear little relationship with market prices we econometrically estimate shadow prices of maize using data from a nationally representative survey of rural households in mexico shadow prices are significantly higher than the market price for traditional but not improved maize varieties they are particularly high in the indigenous areas of southern and southeastern mexico indicating large de facto incentives to maintain traditional maize there

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

job proximity and the urban employment problem do suitable nearby jobs improve neighbourhood employment rates due to a scarcity of small area jobs data much of the spatial mismatch literature has not directly addressed the impact of nearby jobs on neighbourhood employment rates such analysis is particula

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

residential choice mobility and the labor market abstract there is substantial evidence suggesting that the process of suburbanization creates new job opportunities that are not equally exploited by all workers in order to explain this phenomenon a simple model is developed which incorporates borrowing constraints as an important restriction on moving decisions obstructing the necessary labor flows between jurisdictions required to equalize net wages in essence people who cannot borrow will be restricted in terms of their capability of changing residence location and therefore will have limited possibilities of working in distant labor markets or they will be subject to excessive commuting furthermore the labor allocation induced by households behavior facing these constraints affects consumer welfare production and producers profits the outcomes with perfect credit markets and with borrowing restrictions are calculated and the economic welfare levels are compared as wages are flexible they adjust to reflect the relative scarcity of workers present in each jurisdiction consequently some of the negative effects of the borrowing constraints are compensated so the outcomes cannot be easily compared some numerical examples are constructed to have an idea of the possible outcomes under different conditions finally it is found that allowing for moving cost deductions from taxable income may help to alleviate the problem

income class modal choice and urban spatial structure abstract this paper analyzes the impacts of urban transportation system changes and income changes on the welfare of people and on the urban spatial structure in a setting where the income level differs between two groups and two transportation modes compete with each other in a city it is demonstrated that an improvement in some transport facility will not necessarily increase the welfare level of every household and at times decreases the welfare of some households it also is argued that under particular situations an improvement in a particular transport mode may produce a contraction in the city size rather than an expansion similarly an increase in income of one group might have an adverse effect on the welfare of another income group as a result of competition in the land market

on the job search some empirical evidence from britain abstract this paper considers evidence from the labour force survey concerning job search by employed workers the unconditional probability of observing on the job search is decomposed into the product of two constituent probabilities upon which maximum likelihood estimation is performed the analysis facilitates the identification of who searches and whether search takes place in work or from unemployment temporary or part time employment encourages continued search by men but not women skilled workers search more than the unskilled and demonstrate a preference for employed search inter industry wage relativities encourage search on the job job tenure is a significant determinant of the quality of a job match and the subsequent likelihood that on the job search is undertaken employed job seekers adopt search strategies that are more readily integrated into a working environment

search in cities the aim of this paper is to expose the recent developments of urban search models which incorporate a land market into a search matching framework using these models we will be able to explain why unemployment rates vary within a city how city structure affects workers labor market outcomes how unemployment benefits and the job destruction rate affect the growth of cities and why workers living far away from job centers search less intensively and experience higher unemployment rates than those residing closer to jobs we are also able to explain why as compared to whites black workers spend more time commuting to work but travel less miles and search for jobs over a smaller area

ethnic variation in commuting propensity and unemployment spells some u k evidence abstract this paper uses 1987 88 u k survey data from the unemployment inflow to investigate the ability of ethnic variation in commuting willingness to account for longer non white unemployment spells the study is motivated by the possibility that ethnic minorities are at greater risk of spatial mismatch unemployment because they are more geographically restrictive in their job seeking activities our findings support this hypothesis and indicate that lower commuting willingness explains about 20 of the differential between the average unemployment spells of ethnic minorities and whites

an empirical model of employed search unemployed search and nonsearch the 1969 1971 national longitudinal surveys data on young men were used to study the employed worker s choice among employed search unemployed search and not searching for a new job we assume that an unobserved variable search intensity governs this choice such that unemployed search involves a greater intensity than employed search which of course is associated with greater intensity than nonsearch the principal results are that current wages seniority collective bargaining coverage employment outside construction and employment by government are each ceteris paribus negatively associated with search intensity further each of these variables lowers the probability of not searching and raises the probabilities of employed and unemployed job search

commuting migration housing and labour markets complex interactions commuting migration housing and labour markets are important for the overall economy and for the everyday life of many people commuting makes up a large part of all journeys world wide and many resourcedemanding transport investment projects are initiated to cope with this type of travelling in a range of countries increasing flows of national and international migration are central determinants of demographic developments in industrialised countries the working age population or those aspiring to be part of the economically active population constitute a large proportion of the total population consequently income earned through working represents a major component of total earnings in these economies cahuc and zylberberg 2004 in order to obtain an efficient labour market workers should locate and relocate to where the relevant jobs are to be found from an economic point of view commuting and migration are essential elements for obtaining a well functioning labour market fischer et al 1996 lux and sunega 2012 zabel 2012 finally housing is a basic good and for many people rents or loan repayments make up a relatively large proportion of their overall budget oecd 2011 moreover housing represents a dominating element of homeowners wealth or equity due to its central role during the financial and economic crisis starting around 2007 it has become clear that housing prices are important for the development of the overall economy in many countries for example muellbauer and murphy 2008 zabel 2012 housing and labour markets are linked in many ways when explaining these links it is useful to start with some of the distinguished features of housing markets as already mentioned houses frequently constitute a major part of households wealth moreover earned income from employment is a major

racial differences in residential and job mobility evidence concerning the spatial mismatch hypothesis abstract the spatial mismatch hypothesis asserts that job decentralization adversely impacts the labor market outcomes of african americans this paper tests whether race and job access have an independent effect on the probability of a joint residential move and job change no evidence is found to indicate that race directly influences the joint probability the paper finds however that poor job access has an independent negative effect on the probability of a joint residential move and job change because african american residences are heavily concentrated in american central cities these results suggest that african american workers may not be able to fully adjust as new jobs are created in the suburbs

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

who benefits from local oil and gas employment labor market composition in the oil and gas industry in texas and the rest of the united states abstract this paper examines local labor market outcomes from an oil and gas boom we examine two main outcomes the probability of employment and the log wages of workers employed outside the oil and gas industry for texas and the rest of the united states across gender race and ethnicity we find that men and women gain employment in the oil and gas industry during booms but such gains are much larger for men and are largest for black and hispanic men we also find positive income spillovers for workers in other industries that are similar in magnitude across demographic groups

residential segregation and unemployment the case of brussels this paper investigates the causal effects of the spatial organisation of brussels on unemployment propensities using census data at the individual level the unemployment probability of young adults is estimated while taking into account personal household and neighbourhood characteristics the endogeneity of residential locations is solved by restricting the sample to young adults residing with their parents the potential remaining bias is evaluated by conducting a sensitivity analysis the results suggest that the neighbourhood of residence significantly increases a youngster s probability of being unemployed a result which is quite robust to the presence of both observed and unobserved parental covariates

can commutes be used to test the spatial mismatch hypothesis this paper uses a simple spatial model of urban employment to demonstrate that the relationship between spatial mismatch and commuting times is indeterminate if employment probabilities decline as

on the job search in a recession this paper is concerned with the behavious of one component of employee job search in one local labour market during a period of severe recession the paper focuses on the relationship between market conditions and the number of employees using the services of employment offices and jobcentres in analysing this relationship over time the paper stresses the need to adopt a flow approach in such empirical studies of the labour market often as in this case explanatory variables can affect inflows and outflows to labour market stocks in different directions and misleading conclusions may therefore be drawn if only the traditional stock analysis is conducted a further concern of the paper is to examine whether the relationship between market conditions and job search differs between male and female employees
