input allocation workforce management and productivity spillovers evidence from personnel data this article shows how input heterogeneity triggers productivity spillovers at the workplace in an egg production plant in rural peru workers produce output combining effort with inputs of heterogeneous quality exploiting variation in the productivity of inputs assigned to workers we find evidence of a negative causal effect of an increase in coworkers daily output on own output and its quality we show theoretically and suggest empirically that the effect captures free riding among workers which originates from the way the management informs its dismissal decisions our study and results show that input heterogeneity and information on input quality contribute to determine the shape of incentives and have implications for human resource management production management and the interaction between the two counterfactual analyses show that processing information on inputs or changing their allocation among workers can generate significant productivity gains

marshall s scale economies using panel data this paper estimates plant level production functions for machinery and high tech industries that allow for scale externalities from other plants in the same industry locally and from the scale or diversity of local economic activity outside the own industry the paper finds that the count of other own industry plants representing a count of local information spillover sources has strong productivity effects in high tech but not machinery industries single plant firms both benefit more from and generate greater external benefits than corporate plants given their greater reliance on external environments on dynamic externalities high tech single plant firms benefit also from the scale of past own industry activity i find little evidence of economies from the diversity or scale of local economic activity outside the own industry

tourism and economic development evidence from mexico s coastline tourism is a fast growing services sector in developing countries this paper combines a rich collection of mexican microdata with a quantitative spatial equilibrium model and a new empirical strategy to study the long term economic consequences of tourism both locally and in the aggregate we find that tourism causes large and significant local economic gains relative to less touristic regions that are in part driven by significant positive spillovers on manufacturing in the aggregate however these local spillovers are largely offset by reductions in agglomeration economies among less touristic regions so that the national gains from trade in tourism are mainly driven by a classical market integration effect

on the optimal design of place based policies a structural evaluation of eu regional transfers we quantify general equilibrium effects of place based policies in a multi region framework with population mobility trade and agglomeration economies using detailed data on eu transfers we infer the local effects of different transfer types on productivity income and transportation cost based on these estimates and the general equilibrium model we derive the spatial distribution of economic activity and the resulting aggregate welfare effects if i no transfers were paid and taxes set to zero ii transfers were distributed uniformly iii transfers were welfare optimally distributed characterizing the optimal distributions we reveal complementarities between transfer types and between transfers and local endowments

peer pressure and partnerships partnerships and profit sharing are often claimed to motivate workers by giving them a share of the pie but in organizations of any significant size the free rider effects would seem to choke off

changes in transportation infrastructure and commuting patterns in us metropolitan areas 1960 2000 population decentralization has been a salient feature of the landscape of most u s urban areas since 1950 nathaniel baum snow 2007 documents that the aggregate population of central cities of the 139 largest metropolitan areas henceforth msas declined by 17 percent between 1950 and 1990 while aggregate msa population growth was 72 percent during this period expansion of the highway network in urban areas accounts for about one third of the gap in central city and msa population growth rates while transport network expansions clearly generated urban population decentralization there is little evidence to date on how this decentralization manifested itself as changes in employment locations and commuting patterns in this paper i present evidence indicating that employment decentralization occurred apace with residential decentralization between 1960 and 2000 such that their relative spatial concentrations remained remarkably unchanged a byproduct has been that most commutes of msa residents no longer involve central cities at all central cities as defined by their geographies in 1960 were the origin and or destination of only 38 percent of commutes made by msa residents in 2000 down from 66 percent in 1960 using planned portions of the interstate highway system as a source of exogenous variation estimates reported in section iii indicate that urban highway construction played a pivotal role in generating this shift new highways primarily increased the number and fraction of commuting flows within suburban areas at the expense of commutes within central cities because within suburb commutes are longer than other types of commutes on average results are consistent with gilles duranton matthew turner s 2009 evidence that the elasticity of kilometers driven with respect to lane kilometers of highways in urban areas is one 1

how successful was the new deal the microeconomic impact of new deal spending and lending policies in the 1930s the new deal during the 1930s was arguably the largest peace time expansion in federal government activity in american history until recently there had been very little quantitative testing of the microeconomic impact of the wide variety of new deal programs over the past decade scholars have developed new panel databases for counties cities and states and then used panel data methods on them to examine the impact of new deal spending and lending policies for the major new deal programs in most cases the identification of the effect comes from changes across time within the same geographic location after controlling for national shocks to the economy many of the studies also use instrumental variable methods to control for endogeneity the studies find that public works and relief spending had state income multipliers of around one increased consumption activity attracted internal migration reduced crime rates and lowered several types of mortality the farm programs typically aided large farm owners but eliminated opportunities for share croppers tenants and farm workers the home owners loan corporation s purchases and refinancing of troubled mortgages staved off drops in housing prices and home ownership rates at relatively low ex post cost to taxpayers the reconstruction finance corporation s loans to banks and railroads appear to have had little positive impact although the banks were aided when the rfc took ownership stakes

personal traits and individual choices taking action in economic and non economic decisions abstract in a large number of decisions the option that does not require a specific action such as filling in a form is chosen frequently it is a stylized fact that opt in or opt out designs for otherwise identical choices lead to vastly different outcomes choice options are chosen more frequently simply because they are the no action alternative or default option however direct empirical evidence on the reasons for the popularity of defaults is scarce we devised a special survey module for the dutch dnb household survey to study potential explanations for default choices we find that the popularity of the default option is related to different personal traits in economic and non economic decisions financially literate individuals are more likely to take action and opt out the default option in economic decision making in non economic decisions procrastination increases the popularity of the default while individuals who care much about the opinion of others are more inclined to deviate from the default

two stage residual inclusion estimation addressing endogeneity in health econometric modeling the paper focuses on two estimation methods that have been widely used to address endogeneity in empirical research in health economics and health services research two stage predictor substitution 2sps and two stage residual inclusion 2sri 2sps is the rote extension to nonlinear models of the popular linear two stage least squares estimator the 2sri estimator is similar except that in the second stage regression the endogenous variables are not replaced by first stage predictors instead first stage residuals are included as additional regressors in a generic parametric framework we show that 2sri is consistent and 2sps is not results from a simulation study and an illustrative example also recommend against 2sps and favor 2sri our findings are important given that there are many prominent examples of the application of inconsistent 2sps in the recent literature this study can be used as a guide by future researchers in health economics who are confronted with endogeneity in their empirical work

the unequal geographic burden of federal taxation in the united states workers in cities offering above average wages cities with high productivity low quality of life or inefficient housing sectors pay 27 percent more in federal taxes than otherwise identical workers in cities offering below average wages according to simulation results taxes lower long run employment levels in high wage areas by 13 percent and land and housing prices by 21 and 5 percent causing locational inefficiencies costing 0 23 percent of income or 28 billion in 2008 employment is shifted from north to south and from urban to rural areas tax deductions index taxes partially to local cost of living improving locational efficiency

a tale of an unwanted outcome transfers and local endowments of trust and cooperation abstract transfers can do good however they can also result in massive failures this paper presents a model that highlights the ambiguous nature of the impact of transfers on local endowments of social capital it then describes an empirical investigation that illustrates that the receipt of eu structural funds causes a deterioration of the endowments of trust and cooperation in the subsidized regions

incentives for managers and inequality among workers evidence from a firm level experiment we present evidence from a firm level experiment in which we engineered an exogenous change in managerial compensation from fixed wages to performance pay based on the average productivity of lower tier workers theory suggests that managerial incentives affect both the mean and dispersion of workers productivity through two channels first managers respond to incentives by targeting their efforts towards more able workers implying that both the mean and the dispersion increase second managers select out the least able workers implying that the mean increases but the dispersion may decrease in our field experiment we find that the introduction of managerial performance pay raises both the mean and dispersion of worker productivity analysis of individual level productivity data shows that managers target their effort towards high ability workers and the least able workers are less likely to be selected into employment these results highlight the interplay between the provision of managerial incentives and earnings inequality among lower tier workers

market externalities of large unemployment insurance extension programs we provide evidence that unemployment insurance affects equilibrium conditions in the labor market which creates significant market externalities we provide a framework for identification of such equilibrium effects and implement it using the regional extension benefit program rebp in austria which extended the duration of ui benefits for a large group of eligible workers in selected regions of austria we show that non eligible workers in rebp regions have higher job finding rates lower unemployment durations and a lower risk of long term unemployment we discuss the implications of our results for optimal ui policy jel e24 j64 j65 r23

unique equilibrium in a model of self fulfilling currency attacks even though self fulfilling currency attacks lead to multiple equilibria when fundamentals are common knowledge we demonstrate the uniqueness of equilibrium when speculators face a small amount of noise in their signals about the fundamentals this unique equilibrium depends not only on the fundamentals but also on financial variables such as the quantity of hot money in circulation and the costs of speculative trading in contrast to multiple equilibrium models our model allows analysis of policy proposals directed at curtailing currency attacks

gibrat s law for all cities two empirical regularities concerning the size distribution of cities have repeatedly been established zipf s law holds the upper tail is pareto and city growth is proportionate census 2000 data are used covering the entire size distribution not just the upper tail the nontruncated distribution is shown to be lognormal rather than pareto this provides a simple justification for the coexistence of proportionate growth and the resulting lognormal distribution an equilibrium theory of local externalities that can explain the empirical size distribution of cities is proposed the driving force is a random productivity process of local economies and the perfect mobility of workers

where does an industry locate abstract this paper presents an econometric model of industrial location and estimates the model for two industries in brazil based on a comprehensive data set the model predicts which cities will or will not have the industry and for these cities with the industry what the scale of operation will be the parameters estimated in a full information context represent the technology of production supply of entrepreneurs and equilibrating error in markets the results are strong and very suggestive and the explanatory power of the model is relatively high the results are used to simulate the impact of industry subsidies on locational patterns

peers at work we study peer effects in the workplace specifically we investigate whether how and why the productivity of a worker depends on the productivity of coworkers in the same team using high frequency data on worker productivity from a large supermarket chain we find strong evidence of positive productiv ity spillovers from the introduction of highly productive personnel into a shift worker effort is positively related to the productivity of workers who see him but not workers who do not see him additionally workers respond more to the presence of coworkers with whom they frequently interact we conclude that social pressure can partially internalize free riding externalities that are built into many workplaces jel j24 l81 m54

quitters never win the adverse incentive effects of competing with superstars internal competition may motivate worker effort yet the benefits of competition may depend critically on workers relative abilities large skill differences may reduce efforts i use panel data from professional golf tournaments and find that the presence of a superstar is associated with lower performance on average golfers first round scores are approximately 0 2 strokes worse when tiger woods participates relative to when woods is absent the overall tournament effect is 0 8 strokes the adverse superstar effect varies with the quality of woods s play there is no evidence that reduced performance is attributable to media attention intensity or risky strategy adoption

do special economic zones induce developmental spillovers evidence from india s states abstract do special economic zones induce local development research drawing on the case of china s special economic zones suggests that subnational polities can target the location of export zones in order to catalyze local and regional socioeconomic development since 2006 a number of indian states have pushed forward similar zones in the face of accusations of land grabbing arguing that the zones will be engines for improvement in exports employment and infrastructure i argue that local development spillovers are an important albeit previously understudied dimension by which to evaluate the effects of special economic zones i then present the first systematic analysis of the developmental effects of india s sezs leveraging an original dataset on their locations together with 2001 and 2011 census data containing a host of social and economic developmental variables the findings show these sezs have failed to bring about local socioeconomic development to explain this absence of developmental spillovers i provide a theoretical framework based on the crucial role of political economy incentive structures facing local politicians i outline the mechanism through which indian state politicians use state owned development corporations for rent capture undermining the potential effectiveness of sezs and leading to their developmental failures the combination of available means for extracting rents and the limited political constraints on such rent extraction leads to a lack of developmental spillovers this framework can also help to explain the difference in the effects of sezs in india and in china these findings have theoretical importance for understanding the conditions under which subnational polities can use export zones and other export policies to catalyze development and practical implications for understanding the mixed pattern of sez success across the world

the economics of density evidence from the berlin wall this paper develops a quantitative model of internal city structure that features agglomeration and dispersion forces and an arbitrary number of heterogeneous city blocks the model remains tractable and amenable to empirical analysis because of stochastic shocks to commuting decisions which yield a gravity equation for commuting flows to structurally estimate agglomeration and dispersion forces we use data on thousands of city blocks in berlin for 1936 1986 and 2006 and exogenous variation from the city s division and reunification we estimate substantial and highly localized production and residential externalities we show that the model with the estimated agglomeration parameters can account both qualitatively and quantitatively for the observed changes in city structure we show how our quantitative framework can be used to undertake counterfactuals for changes in the organization of economic activity within cities in response for example to changes in the transport network

local economic development agglomeration economies and the big push 100 years of evidence from the tennessee valley authority we study the long run eects of one of the most ambitious place based economic development policies in u s history the tennessee valley authority using a rich panel dataset of counties we conduct an evaluation of the dynamic eects of the tva on local economies in the seventy years following the program s inception we nd that the tva led to short run gains in agricultural employment that were eventually reversed while impacts on manufacturing employment continued to intensify well after the program s subsidies had lapsed a pattern consistent with the presence of strong agglomeration economies in the manufacturing sector economists have long cautioned that the local gains created by place based policies may be oset by losses elsewhere yielding ambiguous eects on the u s as a whole building on the framework in glaeser and gottlieb 2008 we develop a novel approach to assessing the aggregate consequences of shifting the spatial distribution of manufacturing employment our ndings suggest the aggregate productivity gains associated with relocating manufacturing activity to the tva region were probably minimal

limited entrepreneurial attention and economic development economic development depends on the allocation of entrepreneurial resources to efforts to discover new profit opportunities limited entrepreneurial attention is allocated between maintaining current activities and starting new activities this paper addresses the problem of allocating limited entrepreneurial attention in a variety of contexts the issues that are addressed are product improvement and new product development the choice of career as an innovative entrepreneur a managerial entrepreneur or a salaried employee the venture capitalist s attention to current and new ventures and funds the writing of internal contracts and market contracts and the supervising of current employees and hiring additional employees

the enduring impact of the american dust bowl short and long run adjustments to environmental catastrophe the 1930 s american dust bowl was an environmental catastrophe that greatly eroded sections of the plains analyzing new data collected to identify low medium and high erosion counties the dust bowl is estimated to have immediately substantially and persistently reduced agricultural land values and revenues during the depression and through at least the 1950 s there was limited reallocation of farmland from activities that became relatively less productive agricultural adjustments such as reallocating land from crops to livestock recovered only 14 to 28 of the initial agricultural cost the economy adjusted predominately through migration rather than through capital inows and increased industry

work environment and individual background explaining regional shirking differentials in a large italian firm the prevalence of shirking within a large italian bank appears to be characterized by significant regional differentials in particular absenteeism and misconduct episodes are substantially more prevalent in the south we consider a number of potential explanations for this fact different individual backgrounds group interaction effects sorting of workers across regions differences in local attributes different hiring policies and discrimination against southern workers our analysis suggests that individual backgrounds group interaction effects and sorting effects contribute to explaining the north south shirking differential none of the other explanations appears to be of first order importance i introduction whether individual behavior is determined by group interactions or by individual background is undoubtedly a fundamental question for the social sciences this question presented itself forcefully when we stumbled onto the following piece of evidence there appear to be significant regional differentials in the prevalence of shirking among the employees of a large italian bank in particular absenteeism and misconduct episodes are considerably more frequent in the southern branches of the bank in this paper we examine several potential explanations for this fact first individual preferences for shirking versus working may differ according to one s region of hirth we will refer to this hj othesis as one of different individual hackgrounds the second possibility is one of locational sorting low shirking types may tend to migrate to the north high shirking types may tend to migrate to the south or hoth third the northern and southern

nature versus nurture the environment s persistent influence through the modernization of american agriculture technological innovation in agriculture was substantial during the 20th century is modern technological control of the environment replacing a primitive dependency on natural advantages and disadvantages or has agricultural production remained persistently dependent on the environment this paper estimates how the 20th century modernization of united states plains agriculture changed the impact of environmental characteristics on agricultural land values despite substantial technological innovation and rising land values from 1945 to 2002 counties environmental characteristics largely maintained influence on land values environmental change has become no less costly as technological innovation has not reduced the importance of natural advantages or disadvantages

barbed wire property rights and agricultural development this paper examines the impact on agricultural development of the introduction of barbed wire fencing to the american plains in the late nineteenth century without a fence farmers risked uncompensated damage by others livestock from 1880 to 1900 the introduction and near universal adoption of barbed wire greatly reduced the cost of fences relative to the predominant wooden fences especially in counties with the least woodland over that period counties with the least woodland experienced substantial relative increases in settlement land improvement land values and the productivity and production share of crops most in need of protection this increase in agricultural development appears partly to reflect farmers increased ability to protect their land from encroachment states inability to protect this full bundle of property rights on the frontier beyond providing formal land titles might have otherwise restricted agricultural development

trade liberalization and regional dynamics abstract we study the evolution of trade liberalization s effects on brazilian local labor markets regions facing larger tariff cuts experienced prolonged declines in formal sector employment and

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

do place based tax incentives create jobs abstract in this paper we evaluate the effectiveness of place based payroll taxes in stimulating local employment by exploiting a unique policy setting in norway where a system of geographically differentiated payroll taxes was suddenly abolished due to an eu regulation the reform was enforced independently of the regional labor market developments creating arguably exogenous variation in the payroll tax rates that firms in different local labor markets faced over time we find evidence of partial shifting of payroll tax increases on to worker wages as well as a significant decline in local employment these findings suggest that in settings with some degrees of wage rigidity place based payroll tax incentives can be effective in stimulating local employment

clean evidence on peer effects we study subjects who were asked to fill letters into envelopes with a remuneration independent of output in the pair treatment two subjects worked at the same time in the same room and peer effects were possible in the single treatment subjects worked alone and peer effects were ruled out we find evidence of peer effects in the pair treatment because the standard deviations of output are smaller within pairs than between pairs moreover average output is higher in the pair treatment thus peer effects raise productivity finally low productivity workers are the most sensitive to the behavior of peers

oaxaca blinder as a reweighting estimator the classic regression based estimator of counterfactual means studied by ronald oaxaca 1973 and alan blinder 1973 is shown to constitute a propensity score reweighting estimator based upon a linear model for the conditional odds of being treated

zipf s law for cities an explanation zipf s law is a very tight constraint on the class of admissible models of local growth it says that for most countries the size distribution of cities strikingly fits a power law the number of cities with populations greater than s is proportional to 1 s suppose that at least in the upper tail all cities follow some proportional growth process this appears to be verified empirically this automatically leads their distribution to converge to zipf s law

interactions between workers and the technology of production evidence from professional baseball this paper examines how the effort choices of workers within the same firm interact with each other in contrast to the existing literature we show that workers can affect the productivity of their co workers based on income maximization considerations rather than relying on behavioral considerations such as peer pressure social norms and shame theoretically we show that a worker s effort has a positive effect on the effort of co workers if they are complements in production and a negative effect if they are substitutes the theory is tested using panel data on the performance of baseball players from 1970 to 2003 the empirical analysis shows that a player s batting average significantly increases with the batting performance of his peers but decreases with the quality of the team s pitching furthermore a pitcher s performance increases with the pitching quality of his teammates but is unaffected by the batting output of the team these results are inconsistent with behavioral explanations which predict that shirking by any kind of worker will increase shirking by all fellow workers the results are consistent with the idea that the effort choices of workers interact in ways that are dependent on the technology of production these findings are robust to controlling for individual fixed effects and to using changes in the composition of one s co workers in order to produce exogenous variation in the performance of one s peers

evaluating the efficiency and equity of federal fiscal equalization abstract theoretically federal transfers that make household location decisions efficient should ignore local cost differences subsidize positive externalities and offset differences in federal tax payments and local taxes levied on non residents but not local tax revenues from residents transfers that redistribute resources equitably across regions will likely target areas with individuals of low earnings potential or low real incomes applying these criteria empirically canadian equalization policy appears neither efficient nor equitable but exacerbates pre existing inefficiencies and underfunds minorities locational inefficiencies cost canada 0 41 of income annually and cause over funded provinces to have populations of 30 beyond their efficient long run levels

the local socio economic impacts of large hydropower plant development in a developing country abstract despite extensive discussion in the literature about the socio economic impacts of hydropower development on surrounding communities there is 1 a lack of quantitative studies that look at impacts over extended periods of time and 2 a lack of studies including multiple projects in the context of a developing country here we use econometric methods to evaluate the relationship between county level socio economic indicators and hydropower development for 56 brazilian hydropower plants built between 1991 and 2010 we find that counties that built hydropower plants had greater gdp and tax revenues during their first few years of development than a control group that consisted of counties with hydropower projects planned but not yet built however those positive economic effects were short lived

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

nonparametric instrumental variables estimation abstract in many economic models objects of interest are functions which satisfy conditional moment restrictions economics does not restrict the functional form of these models motivating nonparametric methods in this paper we review identification results and describe a simple nonparametric instrumental variables npiv estimator we also consider a simple method of inference in addition we show how the ability to uncover nonlinearities with conditional moment restrictions is related to the strength of the instruments we point to applications where important nonlinearities can be found with npiv and applications where they cannot

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

place based policies heterogeneity and agglomeration place based policies though hardly new have just begun to attract serious attention from econ omists as evidence on the effects of these pro grams begins to trickle in it is useful to revisit the theoretical rationale for spatially targeted subsidies why after all should governments pay firms to move to less productive areas and incentivize workers to live in neighborhoods they don t like and who ultimately benefits from these subsidies in a general equilibrium environment i study here some stylized models of spatial equilibrium designed to answer these questions my conclusions are shown to depend critically upon the degree of preference hetero geneity in the population and the structure of any agglomeration economies

government programs can improve local labor markets evidence from state enterprise zones federal empowerment zones and federal enterprise communities 1 abstract federal and state governments spend well over a billion dollars a year on programs that encourage employment development in disadvantaged labor markets through the use of subsidies and tax credits in this paper we use an estimation approach that is valid under relatively weak assumptions to measure the impact of state enterprise zones entzs federal empowerment zones empzs and federal enterprise community entc programs on local labor markets we find that all three programs have positive statistically significant impacts on local labor markets in terms of the unemployment rate the poverty rate the fraction with wage and salary income and employment further the effects of empz and entc designation are considerably larger than the impact of entz designation we find that our estimates are robust to allowing for a regression to the mean effect we also find that there are positive but statistically insignificant spillover effects to neighboring census tracts of each of these programs thus our positive estimates of these program impacts do not simply represent a transfer from the nearest non treated census tract to the treated census tract our results are noteworthy for several reasons first our study is the first to jointly look at these three programs thus allowing policy makers to compare the impacts of these programs second our paper along with a concurrent study by neumark and kolko 2008 is the first to carry out the estimation accounting for overlap between the programs third our estimation strategy is valid under weaker assumptions than those made in many previous studies we consider three comparison groups and let the data determine the appropriate group fourth in spite of our conservative estimation strategy by looking at national effects with disaggregated data we show that entz designation generally has a positive effect on the local labor market while most previous research on entzs much of which used more geographically aggregated data to look at state specific effects did not find any significant impacts fifth we note that there is little or no previous work on entcs overall our results strongly support the efficacy of these labor market interventions

the employment impact of poland s special economic zones policy abstractin 1994 poland launched a special economic zones experiment to maintain employment structures outside the major cities using difference in difference estimations this paper evaluates whether the policy has been successful in its primary objective which is to sustain employment in gminas communes more likely to be negatively affected by the economic transition a significant and positive effect of the policy on employment is documented but with some negative spillovers at the policy level as zones start to spread rapidly accounting for covariates timing policy spillovers and reducing imbalance through matching the average treatment effect for employment is estimated to be 60

productivity spillovers in team production evidence from professional basketball we estimate a model where workers are heterogeneous both in their own productivity and in their ability to facilitate the productivity of others we use data from professional basketball to measure the importance of peers in productivity because we have clear measures of output and members of a worker s group change on a regular basis our empirical results highlight that productivity spillovers play an important role in team production despite this we find that worker compensation is largely determined by own productivity with little weight given to productivity spillovers

skill transferability migration and development evidence from population resettlement in indonesia we use a natural experiment in indonesia to provide causal evidence on the role of location specific human capital and skill transferability in shaping the spatial distribution of productivity from 1979 1988 the transmigration program relocated two million migrants from rural java and bali to new rural settlements in the outer islands villages assigned migrants from regions with more similar agroclimatic endowments exhibit higher rice productivity and nighttime light intensity one to two decades later we find some evidence of migrants adaptation to agroclimatic change overall our results suggest that regional productivity differences may overstate the potential gains from migration
