We develop a model of dynamic platform formation under positive platform externalities. Users can switch between an incumbent and entrant platforms, switching opportunities arise stochastically and users can choose whether to accept or reject an opportunity to switch. For homogeneous users, we characterize the incumbency advantage implied by a given equilibrium realization of the switching process. For linear utility, incumbency advantage increases in the mean and dispersion of the incumbent’s share during the switching process, which captures the momentum and coordination of the process. Heterogeneity in preferences may lead some users to delay their switching or never switch at all. Assuming that switching opportunities arrive according to a Poisson process, users switch to the entrant platform if the average preference favors the entrant and if preferences are not too polarized.

We provide new evidence on the effect of the unemployment insurance (UI) weekly benefit amount on unemployment insurance spells based on administrative data from the state of Missouri covering the period 2003-2013. Identification comes from a regression kink design that exploits the quasi-experimental variation around the kink in the UI benefit schedule. We find that UI durations are more responsive to benefit levels during the recession and its aftermath, with an elasticity between 0.65 and 0.9 as compared to about 0.35 pre-recession.

In countries confronting the issue of low fertility such as Japan, dual trends showing higher regional population density associated with lower fertility rates are being confirmed. It is therefore an important theme for analysis to deepen discussions related to reducing regional fertility disparities by increasing fertility through the implementation of comprehensive childcare support policies, which might facilitate the striking of a balance between child-rearing and work, even in highly populated regions. As described herein, we constructed a simple theoretical two-region overlapping generations (OLG) by incorporating migration and land prices. Using it, we analyzed the effects of population density and childcare services on fertility. Results elucidated the following three points. First, in the presence of congestion costs associated with increased population density, the fertility rate of the region decreases with increased population density. However, if the time cost of child-rearing is brought down by raising the level of the childcare services provided in the region, then the effect of increased population density on fertility can be restrained. Second, when the effect of population size on productivity is less than a certain level, improvement in the childcare services raises the relative ratio of the population density. When the effect of population size on productivity exceeds a certain level, however, the relative ratio of the population density decreases if the relative ratio of the time cost of child-rearing decreases as a result of childcare service reform. Third, where each region imposes a payroll tax on its residents and uses its tax revenue as the financial resources to adopt a decentralized strategy of providing childcare services to its region, the level of childcare services that maximizes the utility of a representative agent in each region is independent of the childcare services of any other region. Therefore, manipulation of the level of childcare services becomes a dominant strategy.

Using comprehensive data for German establishments (1999-2008), we estimate plant-level production functions to analyze if 'cultural diversity' affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate regional labor force where the plant is located. We find that a larger share of foreign workers –either in the establishment or in the region –does not affect productivity. However, there are strong spillovers associated with the degree of cultural heterogeneity. The aggregate level is, quantitatively, at least as important as the workforce composition inside the establishment. Diversity thus seems to induce externalities beyond the boundaries of a single firm; it improves local business environments.

Summary Unlike migration, scant attention has been paid to the phenomenon of commuting by workers in developing countries. This paper fills this gap by using a nationally representative data set from India to analyze factors that affect the decision of workers to commute across rural and urban areas daily. Our results suggest that regions with large peripheral urban areas or concentration of secondary sector jobs are more likely to have commuting workers. Regional rural and urban unemployment rates and rural–urban wage differentials are important push and pull factors in the decision to commute.

Previous research suggests that the local stock of human capital creates positive externalities within local labor markets and plays an important role in regional economic development. However, there is still considerable uncertainty over what types of human capital are most important. Both national and local policymakers in the U.S. have called for efforts to increase the stock of college graduates in science, technology, engineering, and mathematics (STEM) fields, but data availability has thus far prevented researchers from directly connecting STEM education to human capital externalities. This paper uses the 2009–2011 American Community Survey to examine the external effects of college graduates in STEM and non-STEM fields on the wages of other workers in the same metropolitan area. I find that both types of college graduates create positive wage externalities, but STEM graduates create much larger externalities.

The relation between income and migration intentions can be monotonically decreasing, increasing, or inverse U-shaped, dependent on the level of migration cost relative to wealth and if individuals are credit constrained. Using unique individual level data, covering countries in three geographic regions – sub-Saharan Africa, Asia, and Latin America – we show that migration intentions respond to individual wealth, and that the pattern differs across the country groups studied in a manner compatible with the predictions of our simple model. We also show that contentment with various dimensions of local amenities, such as public services and security, are key determinants of migration intentions.

The living environment plays a key role in the "Aging in Place" strategy. We studied the influence of the built environment on the health status of elderly people living in Brussels. Using census and geo-coded data, we analysed whether built environment factors were associated with poor self-assessed health status and functional limitations of elderly residents (aged 65 and over). We concluded that evidence of such an association is weak and vulnerable to the composition of the neighbourhood.

One goal of state merit-based financial aid programs is to increase the stock of college-educated labor in the state by retaining college-educated persons in the state after college. However, there has been surprisingly little research on whether state merit aid programs are effective at this goal. This paper investigates the effect of state merit aid programs on the post-college location of 24–30 year olds. We use decennial census and American Community Survey microdata to consider post-college retention effects in the 25 states that implemented merit aid programs between 1991 and 2004. Our preferred specification implies that strong state merit aid programs on average increase the probability that a college attendee lives in his or her birth state during ages 24–30 by 2.76 percentage points. We also estimate the effect for individual states and find meaningful differences across states in the effect of merit aid programs on in-state post-college retention and explore explanations for these differences.

This study uses cross-sectional data to investigate regional differences in women's participation in the labor market. Women's participation is high in the northern coastal region of Japan. This high rate of participation is caused by the fact that married women with children participate as regular full-time employees. Supply and demand factors explain part of the differences, but regional effects remain even after controlling for them. I attribute the high participation in the northern coastal region to long-standing norms regarding women's work.

I investigate the effect of improvements to the transportation infrastructure on changes in location patterns of population in Barcelona, Spain between 1991 and 2006. At a census tract level, I verify and extend the finding of Baum-Snow (2007a) that transportation improvements cause suburbanization: (1) improvements to the highway and railroad systems foster population growth in suburban areas; (2) the transit system also affects the location of population inside the central business district (CBD). To estimate the causal relationship between the growth of population (density) and transportation improvements, I rely on an instrumental variables estimation that uses distances to the nearest Roman road, the nearest 19th century main road, and the nearest 19th century railroad network as instruments for the 1991–2001 changes in distance to the nearest highway ramp and the distance to the nearest railroad station.

This study develops an on-the-job search model involving spatial structure. In this model, workers are either employed and commuting frequently to a central business district (CBD) or unemployed and commuting less frequently to the CBD to search for a job. When an unemployed worker succeeds in off-the-job search, the quality of the job match is determined stochastically: a good match yields high-productivity whereas a bad match yields low-productivity. Although a high-productivity worker does not search for a new job, a lowproductivity worker decides whether to conduct an on-the-job search, which would require additional commuting to the CBD. Analysis of this model demonstrates that in equilibrium, the relocation path of workers corresponds to their career path, while welfare analysis demonstrates that such a spatial structure distorts firms f decision regarding the posting of vacancies.

This paper develops a tractable dynamic microeconomic model of migration decisions that is aggregated to describe the behavior of interregional migration. Our structural approach allows us to deal with dynamic self-selection problems that arise from the endogeneity of location choice and the persistency of migration incentives. Keeping track of the distribution of migration incentives over time has important consequences for the econometrical treatment, because the dynamics of this distribution influences the estimation of structural parameters, such as migration costs. For US interstate migration, we obtain a cost estimate of less than one-half of an average annual household income. This is substantially smaller than the migration costs estimated by previous studies. We attribute this difference to the treatment of the dynamic self-selection problem.

This paper asks whether population growth is conducive to the sustainability of cooperation. A simple model is developed in which farmers who live around a circular lake engage in trade with their adjacent neighbors. The payoffs from this activity are governed by a prisoner's dilemma "rule of engagement." Every farmer has one son when the population is not growing, or two sons when it is growing. In the former case, the son takes over the farm when his father dies. In the latter case, one son stays on his father's farm, whereas the other son settles around another lake, along with the "other" sons of the other farmers. During his childhood, each son observes the strategies and the payoffs of his father and of the trading partners of his father, and imitates the most successful strategy when starting farming on his own. Then mutant defectors are introduced into an all-cooperator community. The defector strategy may spread. A comparison is drawn between the impact in terms of the sustainability of cooperation of the appearance of the mutants in a population that is not growing, and in one that is growing. It is shown that the ex-ante probability of sustaining the cooperation strategy is higher for a community that is growing than for a stagnant community.

This paper, using individual data from Japan, explores how the circumstances of where a person resides is related to the degree of their investment in social capital. Controlling for unobserved area-specific fixed effects and various individual characteristics, I found: (1) not only is the rate of homeowners in a locality positively related to investment in social capital, but also the rate of homeownership there increases an individual's investment in social capital and (2) the effect of local neighborhood homeownership is distinctly larger than that of an individual's when endogeneity bias is controlled for using instruments such as land price and the rental price of an apartment.

This paper considers the effects of the local human capital level and the presence of higher education institutions on the quality of life in U.S. metropolitan areas. The local human capital level is measured by the share of adults with a college degree, and the relative importance of higher education institutions is measured by the share of the population enrolled in college. This paper finds that quality of life is positively affected by both the local human capital level and the relative importance of higher education institutions. Furthermore, these effects persist when these two measures are considered simultaneously, even though the two are highly correlated. That is the human capital stock and higher education institutions have a shared effect and also separate effects on quality of life.

There is a long-standing debate among academics about the effect of immigration on native internal migration decisions. If immigrants displace natives this may indicate a direct cost of immigration in the form of decreased employment opportunity for native workers. Moreover, displacement would also imply that cross-region analyses of wage effects systematically underestimate the consequences of immigration. The widespread use of such area studies for the US and other countries makes it especially important to know whether a native internal response to immigration truly occurs. This paper introduces a microsimulation methodology to test for inherent bias in regression models that have been used in the literature. We show that some specifications have built biases into their models, thereby casting doubt on the validity of their results. We then provide a brief empirical analysis with a panel of observed US state-by-skill data. Together, our evidence argues against the existence of native displacement. This implies that cross-region analyses of immigration’s effect on wages are still informative.

This paper provides supportive evidence to the notion that the division of labour is limited by the extent of the (local) market. We first propose a theoretical model. Its main prediction is that scarce specialists occupations are over-represented in large cities. Using census data for French cities, we find strong empirical support for this prediction.

This paper investigates the determination of population and employment changes for the 125 Local Government Areas of Queensland over the 1996–06 period. The intention is to determine the flow of causality from employment to population growth and/or vice versa. Unlike previous similar studies, the role of geographic location is formally investigated using techniques from the field of spatial data analysis. Overall, results of previous research are confirmed, in that there is some evidence of bi-directional causality. However, spatial effects are found to be important in the process of regional growth, with regional economic performance in part, determined by the outcomes experienced in neighbouring regions.

Existing studies have explored either only one or two of the mechanisms that human capital externalities percolate at only macrogeographic levels. This paper, by using the 1990 Massachusetts census data, tests four mechanisms at the microgeographic levels in the Boston metropolitan area labor market. We propose that individual workers can learn from their occupational and industrial peers in the same local labor market through four channels: depth of human capital stock, Marshallian labor market externalities, Jacobs labor market externalities, and thickness of the local labor market. We find that all types of human capital externalities are significant across census tracts and blocks. Marshallian labor market externalities and the effect of labor market thickness in terms of industry employment density are significant at the block level. The mechanisms of knowledge spillovers vary across industries and occupations. Different types of externalities attenuate at different speeds over geographic distances. The effect of labor market thickness -- in terms of industry employment density -- decays rapidly beyond 1.5 miles away from block centroid; the effect of human capital depth decays rapidly beyond three miles; while Jacobs externalities decay very slowly, indicating a certain degree of urbanization economies. We conclude that knowledge spillovers are very localized within microgeographic scope in cities that we call, "Smart Cafe Cities."

This research examines wage differences between part-time and full-time workers using microdata from the Spanish Structure of Earnings Survey. The main contribution of the paper is related to the analysis of differences along the wage distribution using econometric decomposition methods and introducing a regional perspective. The evidence shows that part-time workers in Spain experience a significant wage disadvantage. This disadvantage is worse in the case of female workers and it is not homogenous along the wage distribution, being comparatively more relevant for the most qualified women and becoming positive for the most qualified men. However, the disadvantage is practically explained by the endowments of characteristics, with a leading role of segregation of part-time workers in low-wage firms. From a regional perspective, although in the majority of the regions wage differences tend to be explained by endowments of characteristics, there are several regions where the unexplained part of the differential is significant, particularly in the case of male workers. These regional differences seem to be related to differences in the market power of firms at the regional level.

We present new evidence on the wage and mobility of young and old workers, which is difficult to explain using standard human capital theory. Instead, we propose a simple dynamic extension of the Roy model, where worker migration and wages are jointly determined at the individual level. According to this model, a higher moving cost among older workers is the main factor driving the lower mobility among this group. Because of the higher moving costs, older workers require a higher wage increase to move across regions than younger workers, a pattern that is consistent with individual-level U.S. data. We also find an interesting dynamic effect suggesting that, given a persistent labor income shock, a higher future moving cost makes workers more mobile today.

Indirect psychological effects induced by crime are likely to contribute significantly to the total costs of crime beyond the financial costs of direct victimization. Using detailed crime statistics for the whole of Germany and linking them to individual-level mental health information from the German Socio-Economic Panel, we analyze whether local crime rates affect the mental health of residents. We estimate that a one standard deviation increase in local violent crime rates significantly decreases individual mental well-being among residents by, on average, one percent. Smaller effects are found for property and total crime rates. Results are insensitive to migration and not isolated to urban areas, but are rather driven by less densely populated regions. In contrast to previous literature on vulnerability to crime, we find that men, more educated and singles react more to variation in violent crime rates in their neighborhoods. One potential explanation could be that those who are more fearful of crime have developed better coping strategies and, hence, react less to changes in crime. Indirekte psychologische Effekte stellen möglicherweise einen erheblichen Teil der durch Kriminalität verursachten Gesamtkosten dar. Um zu analysieren, ob regionale Kriminalitätsraten die mentale Gesundheit beeinflussen, nutzen wir detaillierte Kriminalitätsinformationen für Deutschland und verknüpfen diese mit Informationen zu individueller mentaler Gesundheit aus dem Sozio-ökonomischen Panel. Unsere Schätzergebnisse implizieren, dass der Anstieg um eine Standardabweichung in der Gewaltverbrechensrate das mentale Wohlbefinden der lokalen Bevölkerung signifikant um durchschnittlich ein Prozent reduziert. Für Eigentumsdelikte und die Gesamtkriminalitätsrate beobachten wir geringere Effekte. Die Ergebnisse werden weder durch Wohnortwechsler beeinflusst noch sind sie auf urbane Regionen begrenzt, sondern sind vielmehr durch weniger dicht besiedelte Regionen getrieben. Im Gegensatz zur Literatur zur Angst vor Kriminalität beobachten wir, dass Männer, höher Gebildete und Alleinstehende sensibler auf Veränderungen in der regionalen Gewaltverbrechensrate reagieren. Eine Erklärung hierfür könnte sein, dass diejenigen, die mehr Angst vor Kriminalität haben, entsprechende Coping-Strategien entwickelt haben und daher auch weniger auf Veränderungen in der Kriminalitätsrate reagieren.

Previous literature shows that internal migration rates are strongly procyclical. This would seem to imply that geographic relocation does not help mitigate negative local economic shocks during recessions. This paper shows that this is not the case. I document that net in-migration rates decreased in areas more affected by the Great Recession. Using various IV strategies that rely on the importance of the construction sector and the indebtedness of households before the crisis, I conclude that internal migration might help to alleviate up to one third of the effects of the crisis on wages in the most affected locations. This is due to a disproportionate decrease in in-migration into those locations rather than an increase in out-migration. More generally, I show that differences in population growth rates across locations are mainly explained by differences in in-migration rates rather than in out-migration rates. I introduce a model to guide the empirical analysis and to quantify the spill-over effects caused by internal migration.

Neighborhood decline is a complex and multidimensional process. National and regional variation in economic and political structures (including variety in national welfare state arrangements), combined with differences in neighborhood history, development and population composition, makes it extremely difficult to identify a unilateral process of neighborhood decline over time. Some scholars have tried to develop all-encompassing models to explain neighborhood decline; others have studied more deeply the relevance of a limited number of factors and developments in processes of decline. The literature has paid little attention to the influence of economic development on neighborhood development, and surprisingly, few studies have focused on the effects of the economic crisis on urban neighborhoods. The recent global economic and financial crisis affected many European and North-American cities in terms of growing unemployment levels and rising poverty in concentrated areas. At the same time, urban investments such as urban restructuring and neighborhood improvement programs have decreased, or come to a halt altogether. By reviewing existing literature, this paper aims to contribute to an understanding of neighborhood decline in light of the economic crisis. By formulating ten hypotheses about the ways in which the economic crisis might interact with processes of neighborhood decline, this paper aims to push the debate on neighborhood decline forward and calls for more contextualized research on neighborhood change. We will highlight challenges for future research and point to factors that need to be taken into consideration in a post-crisis society.

We analyse whether migration is an adaptation that households employ to cope with climate in Ghana and Nigeria. If migration is part of the present adaptation portfolio of households in developing countries, it is reasonable to expect that it will also be an adaptation to future climate change. It is important to stress that we are interested in long-term climatic conditions rather than in short-term weather fluctuations. The data to test these predictions are drawn from two different household surveys: the Nigeria General Household Survey and the Ghana Living Standard Survey. We find a hill-shaped relationship between temperature in the dry sea son and the propensity to migrate in households that operate farms. We also find a significant hill-shaped relationship between precipitations in the wet seasons and the propensity to migrate in farm households. Climate has instead no significant impact on the propensity to migrate in non-farm households. Climate change scenarios generated by General Circulation model reveal that, ceteris paribus, migration may decline in Ghana and in Nigeria.

This paper is the first to link economic theory with empirical life-satisfaction analyses referring to internal migration. We derive an extension of the Roback (1982) model to account for benefits from regional amenities in the utility function, while controlling for income, housing costs, and migration costs. Using highly disaggregated spatial panel information on people’s migration decisions and their life satisfaction for Germany, we provide an empirical investigation of the theoretical model by applying an individual fixed-effects model to rule out selection bias, while accounting for endogeneity of income. We find that short-term benefits from regional amenities represent about 21 percent of household income. These findings are robust to a number of alternative specifications.

The paper presents findings of a large study on socio-economic impacts of the March 2011 earthquake, tsunami and Fukushima nuclear disaster on the Japanese agriculture and food sector. It contains fourteen parts: introduction with the framework of analysis; a brief description of events and their overall social, economic and environmental effects; assessments on affected farms and agricultural resources; progress and challenges of restoration of agricultural communities, lands, infrastructure and businesses; assessments of impacts on food industries; analysis of radioactive contamination of agri-food products; evaluation of the effects on markets, consumers and international trade; analysis of effects on food regulation and inspection system; estimates on farms and agri-businesses damages from the nuclear accident; assessment of overall impact on farms and agricultural resources; assessment of overall impact on agricultural productions; assessment of overall impact on agricultural output and income; assessment of overall impact on farm economy; and conclusion with lessons and recommendations.

The stock of human capital in an area is important for regional economic growth and development. However, highly educated workers are often quite mobile, and there is a concern that public investments in college graduates may not benefit the state if the college graduates leave the state after finishing their education. This paper examines the relationship between the production of college graduates from a state and the stock of college graduates residing in the state using microdata from the decennial census and American Community Survey. The relationship is examined across states and across cohorts within states. The descriptive analysis suggests that the relationship between the production and stock of college graduates has increased over time and is nearly proportional in recent years. Instrumental variables methods are used to estimate causal effects. The preferred instrumental variables results yield an average point estimate for the production-stock relationship of 0.52, but the effect likely decreases with age.

We develop a dynamic labor search model where production and consumption take place in spatially distinct labor markets with varying exposure to domestic and international trade. The model recognizes the role of labor mobility frictions, goods mobility frictions, geographic factors, and input-output linkages in determining equilibrium allocations. We show how to solve the equilibrium of the model without estimating productivities, reallocation frictions, or trade frictions, which are usually difficult to identify. We use the model to study the dynamic labor market outcomes of aggregate trade shocks. We calibrate the model to 38 countries, 50 U.S. states and 22 sectors and use the rise in China's import competition to quantify the aggregate and disaggregate employment and welfare effects on the U.S. economy. We find that China's import competition growth resulted in 0.6 percentage point reduction in the share of manufacturing employment, approximately 1 million jobs lost, or about 60% of the change in the manufacturing employment share not explained by a secular trend. Overall, China's shock increases U.S. welfare by 6.7% in the long-run and by 0.2% in the short-run with very heterogeneous effects across labor markets.

This paper studies how the thick market effect influences local unemployment rate fluctuations. The paper presents a model to demonstrate that the average matching quality improves as the number of workers and firms increases. Unemployed workers accumulate in a city until the local labor market reaches a critical minimum size, which leads to cyclical fluctuations in the local unemployment rates. Since larger cities attain the critical market size more frequently, they have shorter unemployment cycles, lower peak unemployment rates, and lower mean unemployment rates. Our empirical tests are consisten with the predictions of the model. In particular, we find that an increase of two standard deviations in city size shortens the unemployment cycles by about 0.72 months, lowers the peak unemployment rates by 0.33 percentage points, and lowers the mean unemployment rates by 0.16 percentage points.

Governments in many LDCs skew public resources towards urban sectors, despite a majority of citizens residing in rural areas. This paper develops a novel political argument for this urban-bias phenomenon in a framework where all voters, rural and urban, have equal voice, but differ in their access to information. We argue that this difference is sufficient to give governments an incentive to inefficiently over-allocate resources towards urban areas. The bias is shown to worsen during adverse economic times, leading to increased migration. We also examine how voter informativeness affects efficiency of the electoral process in weeding out incompetent governments.

We study a general equilibrium model of global trade and local migration in a continuous geographical space. Trade is based on the Dixit-Stiglitz model of monopolistic competition. Migration is modelled as a local interaction decision process. Incentives for migration are of two types: homogeneous incentives of the group, associated with the identity of taste for higher utility levels, and heterogeneous incentives, due to idiosyncrasies in location taste. The impact of migration on the regional structure is twofold. First, when driven by utility differentials, it contributes to agglomeration because of the presence of increasing returns. Second, when reflecting heterogeneous individual choices, it fosters regional convergence. Furthermore, the size of agglomerations, when they occur, increases with the taste for variety and the proportion of the manufacturing population, and decreases with transport costs.

We exploit the increase in immigration flows into western European countries that took place in the 2000s to assess whether immigration affects crime victimization and the perception of criminality among European natives. Using data from the European Social Survey, the Labour Force Survey and other sources, we provide a set of fixed effects and instrumental variable estimations that deal with the endogenous sorting of immigration by region and with the sampling error in survey based measures of regional immigration shares, whose implications in terms of attenuation bias are investigated by means of Monte Carlo simulations. Our empirical findings show that an increase in immigration does not affect crime victimization, but it is associated with an increase in the fear of crime, the latter being consistently and positively correlated with the natives' unfavourable attitude toward immigrants. Our results reveal a misconception of the link between immigration and crime among European natives.

This paper estimates how effects of shocks to local labor demand on local labor market outcomes vary with initial local economic conditions. The data are on U.S. metro areas from 1979 to 2011. The paper finds that demand shocks to local job growth have greater effects in reducing local unemployment rates if the local economy is initially depressed than if the local economy is booming. Demand shocks have greater effects on local wage rates if the local unemployment rate is initially low, but lesser effects if local job growth is initially high. These different effects of local demand shocks imply that social benefits of adding jobs are two to three times greater per job in more depressed local labor markets, compared to more booming local labor markets.

Over the course of China's economic reforms, a pronounced divergence in the labor force participation patterns of rural and urban elders emerged – rural elders increased their rates of participation while urban elders reduced theirs. In this project, based on the data of the Chinese population censuses of 1982 and 2000, we employ a two-stage procedure to take into account the endogeneity of the residency and labor force participation decisions of older persons. We find that the effect of coresidency with adult children on the labor force participation of older adult differs by urban vs. rural residence. In 1982, the LFPR of urban elders who coresided with their adult children were significantly higher than those who did not coreside. By 2000, this effect completely disappeared. In contrast, in rural areas, coresidency with adult children had a large and significant negative effect on the labor force participation of both male and female elders. This effect diminished only slightly over the reform period. Finally, we decompose the changes over time in elders' labor force participation decisions and find that the response effect for all groups (male and female, urban and rural) is positive, such that, holding the levels of demographic and economic variables constant, each group of elders would have had higher rates of participation in 2000 than in 1982. The remarkable divergence in urban and rural elders' labor force participation trends are due to differences in the relative sizes of their attribute and response effects.

This paper analyses empirically how cross-border consumption varies across product and services categories and across household characteristics. It focuses on the part of cross-border sales that arise due to work-related cross-border crossings; it analyses the cross-border consumption behaviour of cross-border commuter households residing in Belgium, France and Germany and working in Luxembourg. In total, it is estimated that these households spend € 925 million per annum in Luxembourg, reflecting about 17% of their gross annual income from Luxembourg and contributing about 10% to total household final consumption expenditure in Luxembourg. Cross-border consumption expenditure is shown to depend on individual and household characteristics, such as total household income, the number of cross-border commuters in the household, distance between home and work, as well as price level (index) differences between Luxembourg and its neighbouring countries. Cross-border commuters take advantage of existing arbitrage opportunities.

We model centralized school matching as a second stage of a simple Tiebout-model and show that the two most discussed mechanisms, the deferred acceptance and the Boston algorithm, both produce inefficient outcomes and that the Boston mechanism is more efficient than deferred acceptance. This advantage vanishes if the participants get to know their priorities before they submit their preferences. Moreover, the mechanism creates artificial social segregation at the cost of the disadvantaged if the school priorities are based on ex ante known (social) differences of the applicants.

Crossing borders, be it international or regional, often go together with price, wage or indeed wealth discontinuities. This paper identifies substantial wealth differences between Luxembourg resident households and cross-border commuter households despite their similar incomes. The average (median) net wealth difference is estimated to be EUR 367,000 (EUR129,000) and increases for higher percentiles. Using several different regression and decomposition techniques, spatial (regional) differences in real estate price developments, and thus differences in accumulated nominal capital gains are shown to be one main driving factor for these wealth differences. Other factors contributing to the observed wealth differences are differences in age, income, education and other household characteristics.

This paper describes the Longitudinal Survey on Rural Urban Migration in China (RUMiC), a unique data source in terms of spatial coverage and panel dimension for research on labor markets in China. The survey is a collaboration project between the Australian National University, Beijing Normal University and the Institute for the Study of Labor (IZA), which makes data publicly available to the scientific community by producing Scientific Use Files. The paper illustrates the structure, sampling frame and tracking method of the survey, and provides an overview of the topics covered by the dataset, and a review of the existing studies based on RUMiC data.

We analyze the impact of migration on wage, income and the unemployment rate. Using the official Russian statistical database from 1995 to 2010, we calculate a dynamic panel data model with spatial effects. There is a positive spatial effect for wage, income and unemployment rate. There is no significant impact of migration on the unemployment rate. We find a negative relationship between net internal migration and both wages and income, which is explained by the positive effect of emigration and negative effect of immigration for income. However, the migration benefits are not big enough to make a difference on the Gini index across regions. We conclude that migration does not affect the regional -convergence of economic indicators.

We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also demonstrate that, for a low urbanization level, there is a unique steady-state equilibrium where workers do not interact with weak ties, while, for a high level of urbanization, there is a unique steady-state equilibrium with full social interactions. We show that these equilibria are usually not socially efficient when the urban population has an intermediate size because there are too few social interactions compared to the social optimum. Finally, even when social interactions are optimal, we show that there is over-urbanization in equilibrium.

Estimating the effect of 'ethnic capital' on human capital investment decisions is complicated by the endogeneity of location choice of immigrants and the reflection problem. We exploit a rare immigrant settlement policy in Germany to identify the causal impact of parental peer-heterogeneity on the educational outcomes of their children. To identify the direction of peer effect we restrict to no-child-adult-peers who completed their education much before the children in our sample of interest. We find that children of low-educated parents benefit significantly from the presence of high-educated neighbors, with more pronounced effects in more polarized neighborhoods and significant gender heterogeneity. In contrast, we do not find any negative influence coming from the low-educated neighbors. Our estimates are robust to a range of flexible peer definitions. Overall, the findings suggest an increase in parental aspirations as the possible mechanism rather than a direct child-to-child peer effect.

This paper examines the causal impact of education on within-country migration. A major higher education reform took place in Finland in the 1990s. It gradually transformed former vocational colleges into polytechnics and expanded higher education to all regions. The reform created exogenous variation in the regional supply of higher education. Using the reform as an instrument, our estimation results show that polytechnic graduates have a 7.5 (13.7) percentage points higher migration probability during a three-year (six-year) follow-up period than vocational college graduates.

Devastating natural catastrophes lead to severe damages to buildings and infrastructure which have to be eliminated in the aftermath of the event. Thus, the demand for skilled labor and materials increase sharply which in turn leads to significant price increases that should be taken into account in the forecast of catastrophe losses. This interdependency is referred to as the “Demand Surge” effect. The paper at hand presents an extensive econometric analysis and modeling of the Demand Surge effect based on data about 176 natural catastrophes in the US provided by EM-DAT. We find that Demand Surge is positively influenced by the total amount of repair work, by alternative catastrophes in the same region in close temporal proximity, and by a higher amount of insurance claims per event. Furthermore, the Demand Surge effect is more pronounced if the construction sector is in a growth stage. The contribution is a short summary of a working paper presented at the annual meeting of the German Insurance Science Association (DVfVW) in Berlin in March 2013.

This article examines unemployment disparities and efficiency in a densely populated economy with two job centers and workers distributed between them. We introduce commuting costs and search-matching frictions to deal with the spatial mismatch between workers and firms. In equilibrium, there exists a unique threshold location where job-seekers are indifferent between job centers. In a decentralized economy job-seekers do not internalize a composition externality they impose on all the unemployed. Their decisions over job-search are thus typically not optimal and hence the equilibrium unemployment rates are inefficient. We calibrate the model for Los Angeles and Chicago Metropolitan Statistical Areas. Simulations exercises suggest that changes in the workforce distribution have non-negligible effects on unemployment rates, wages and net output.

This paper investigates the effects of tuition fees on the university enrollment and location decision of high school graduates in Germany. After a Federal Constitutional Court decision in 2005, 7 out of 16 German federal states introduced tuition fees for higher education. In the empirical analysis, we use the variation over time and across regions in this institutional change in order to isolate the causal effect of tuition fees on student enrollment and migration. Controlling for a range of regional- and university-specific effects, our results from Difference-in-Differences estimations show that there is generally no effect of tuition fees on internal enrollment rates. However, we find a redirecting effect on first-year students' migratory behavior as indicated by a signicant drop in the gross in-migration rates in fee-charging states. Further, our results point at a stronger migration response of male students, which, however, can mainly be attributed to a 'border effect'. That is, interregional migration flows of male students are redirected from fee-charging universities to those universities that are geographically close by while being located in a non-charging neighboring state. Controlling for these border effects, the relocating trend in long-distance migration of university freshmen does not show any particular gender differences. Diese Studie analysiert Effekte der Einführung von Studiengebühren in Deutschland auf das Einschreibe- und Mobilitätsverhalten von Studienberechtigten. Nach der Entscheidung des Bundesverfassungsgerichts im Jahr 2005, die das vorherige Gebührenverbot für verfassungswidrig erklärte, erhoben 7 von 16 Bundesländern Beiträge für ein Hochschulstudium. Die empirische Analyse nutzt die regionale Variation dieser Reform, um den kausalen Effekt der Gebühreneinführung auf Einschreiberaten und innerdeutsche Migration zu identifizieren. Nach Kontrolle für regionale als auch hochschulspezifische Effekte zeigen die Ergebnisse von Differenz-in-Differenzen-Schätzungen keinen generellen Effekt auf landesinterne Einschreiberaten. Allerdings wird ein Umverteilungseffekt bezüglich der Wanderung von Studienanfängern gefunden, welcher sich in einem signifikanten Rückgang der Brutto-Einwanderungsraten in Gebührenländer zeigt. Dieser Effekt ist für männliche Studienberechtigte stärker ausgeprägt und kann größtenteils einem 'Grenzeffekt' zugeschrieben werden. Dies bedeutet, dass Migrationsströme bei Männern von Gebührenländern umgeleitet werden, und zwar zu Hochschulen in benachbarten Nicht-Gebührenländern, die in der Nähe von Bundeslandgrenzen gelegen sind. Wenn für diesen Grenzeffekt kontrolliert wird, werden keine Geschlechterunterschiede im Wanderungsverhalten über längere Distanzen beobachtet.

In this paper we analyze the unintended effects on mobility of a national place-based policy (SIPTEA) that provides greater unemployment protection in two lagging regions of southern Spain (namely, Extremadura and Andalucía). Using a border identification strategy and (1981 and 1991) census data at the municipal level, we estimate the effects of SIPTEA on population growth, the probability of staying and in-migration in rural areas that are experiencing high unemployment and significant out-migration flows. The results indicate that the policy mitigated population losses by increasing both the probability of staying and in-migration, although the locational inefficiencies implied are not particularly large. We also explore the effects of greater unemployment protection on labor market outcomes. Here, the results indicate that the policy led to a 10- to 13-percentage point increase in unemployment.

The Great Recession had significant economic effects both in the U.S. and around the world. There is evidence that homeownership rates declined during this period, though some immigrants were less severely affected compared to natives. In this paper we investigate the role of several factors in reducing the vulnerability of immigrants in the face of the economic crisis and increasing the probability of their homeownership. Specifically we examine to what extent birthplace networks, savings, length of stay in the U.S., and citizenship status affect the probability of homeownership before the recession and to what extent these impacts have changed since the recession. Using data from Current Population Survey for the years 2000 – 2012 our results suggest that birthplace networks have a significant effect on homeownership and this effect further increases after the onset of recession. Moreover the impact of birthplace network on homeownership is stronger for citizens and those who are not recent immigrants. We also find a decline in the impact of saving and length of stay on the probability of homeownership during 2007-2012 compared to earlier years. In contrast we find an increase in the impact of being a citizen on immigrant homeownership during this period.

The aim of this paper is to outline differences in the socio-demographic and employment characteristics of Estonian people who have worked in a neighbouring country – Finland, Sweden, Latvia or Russia. The empirical part of this paper relies on data from CV Keskus – an online employment portal bringing together jobseekers and vacant job posts. The results of our analysis show that different destination regions – the wealthier countries of Finland and Sweden (referred to as East-West mobility) and Latvia and Russia (referred to as East-East mobility) have attracted workers with different personal and job-related characteristics. Ethnicity and higher education are important determinants in explaining differences between East-West and East-East labour flows. Non-Estonians and people with a higher education have been less likely to work in Finland or Sweden.
