Complements or substitutes? Immigrant and native task specialization in Spain

Learning about the impact that immigration has on the labor market of the receiving nation is a topic of major concern, particularly in Spain, where immigration has more than doubled from 4 percent to roughly 10 percent of the population within a decade. Yet, very little is known about the impact that large immigrant inflows have had on the labor market outcomes of Spanish natives. Furthermore, most studies assume that natives and immigrants are perfect substitutes within skill groups –a questionable assumption given recent findings in the literature. In this paper, we first document that foreign-born workers are not perfect substitutes of similarly skilled native Spanish workers, which may help explain why immigration has not significantly lowered natives’ wages. Instead, immigration has affected the occupational distribution of natives. Specifically, owing to the comparative advantage of foreign-born workers in manual as opposed to interactive tasks, natives relocated to occupations with a lower content of manual tasks –such as technical and alike professional occupations, clerical support jobs, and sales and service occupations. Yet, possibly owing to the significant and simultaneous reduction in the manual to interactive task supply resulting from the increase in the share of native female workers, the increase in the relative supply of manual to interactive tasks from foreign-born workers does not appear to have significantly changed the overall manual to interactive task supply in the Spanish economy

Labor market impacts of states issuing of driver's licenses to undocumented immigrants

Over the last years several states have enacted policies granting undocumented immigrants access to driver's licenses. We exploit the state and temporal variation in the issuing of state driver's licenses to undocumented immigrants to estimate their impact on labor market outcomes. Using 2005 through 2017 data from the American Community Survey, we show that likely undocumented men increase their weekly hours of work in response to the availability of driver's licenses. Perhaps due to their already high labor force participation, the impact is somewhat moderate. We also find no similar impacts among similarly skilled foreign-born Hispanic men who have naturalized. The policy slightly raises commuting time, suggesting changes in work patterns, as well as likely undocumented immigrants’ propensity to have an occupation that requires driving. At a time when anti-immigrant sentiments are at an all-time high, understanding how these policies impact targeted groups and similarly skilled citizens is crucial for maintaining an informed immigration policy debate

Timing is Everything when Fighting a Pandemic: COVID-19 Mortality in Spain

In an effort to contain the spread of the COVID-19 pandemic, many countries around the globe adopted social distancing measures. Previous studies have relied on the geographical and temporal variation in the adoption of non-pharmaceutical interventions (NPIs) to show that early adoption of NPIs is correlated to lower infection and mortality rates. However, due to the non-random adoption of NPIs, the findings may not be interpreted as causal. We address this limitation using a different source of identification –namely, the regional variation in the placement on the pandemic curve at the time of a nationwide lockdown. Our results reveal how, relative to regions for which the lockdown arrived 10+ days after the pandemic's outbreak, regions where the outbreak had just started were able to lower their daily fatality rate by 2.5 deaths per 100,000 inhabitants. We also provide suggestive evidence of contagion deceleration as the main mechanism behind the effectiveness of the early adoption of NPIs in lowering the death rate, rather than increased healthcare capacity

COVID-19 School Closures and Parental Labor Supply in the United States

We examine the role of school closures in contributing to the negative labor market impacts of the COVID-19 pandemic. We collect detailed daily information on school closures at the school-district level, which we merge to individual level data on various employment and socio- demographic characteristics from the monthly Current Population Survey from January 2019 through May 2020. Using a difference-in-differences estimation approach, we gauge how the intensity of school closures affects the labor supply of mothers and fathers of young school-age children. We find evidence of non-negligible labor supply reductions, particularly among mothers. These impacts prove robust to endogeneity checks and persist after accounting for other social-distancing measures in place

Structural Properties of Ego Networks

The structure of real-world social networks in large part determines the evolution of social phenomena, including opinion formation, diffusion of information and influence, and the spread of disease. Globally, network structure is characterized by features such as degree distribution, degree assortativity, and clustering coefficient. However, information about global structure is usually not available to each vertex. Instead, each vertex's knowledge is generally limited to the locally observable portion of the network consisting of the subgraph over its immediate neighbors. Such subgraphs, known as ego networks, have properties that can differ substantially from those of the global network. In this paper, we study the structural properties of ego networks and show how they relate to the global properties of networks from which they are derived. Through empirical comparisons and mathematical derivations, we show that structural features, similar to static attributes, suffer from paradoxes. We quantify the differences between global information about network structure and local estimates. This knowledge allows us to better identify and correct the biases arising from incomplete local information.Comment: Accepted by SBP 2015, to appear in the proceeding

Does emigration affect pro-environmental behaviour back home? A long-term, local-level perspective

This study provides novel evidence on the effects of emigration on pro-environmental behaviour back home. Focusing on the seven successor states of former Yugoslavia, I explore the relationship between people’s present-day pro-environmental action and the local-level intensity of a major guestworker emigration wave that occurred four decades earlier. I find that more intense local-level emigration is associated with a lower likelihood of pro-environmental action; the instrumental variable analysis supports the causal nature of this relationship. This finding supports the conjecture that emigration contributes to greater consumerism at home and therefore reduces pro-environmental behaviour. At the same time, controlling for the intensity of local-level emigration, a higher proportion of women in the local migrant population is associated with a greater likelihood of pro-environmental action. As women are generally more likely to undertake pro-environmental behaviour as well as transfer new norms and practices across borders, this finding supports the hypothesis that migration contributes to a cross-border transmission of pro-environmental norms and practices

Employment Expectations and Gross Flows by Type of Work Contract

There is growing interest in understanding firms’ temporary and permanent employment practices and how institutional changes shape them. Using data on Spanish establishments, we examine: (a) how employers adjust temporary and permanent job and worker flows to prior employment expectations, and (b) how the 1994 and 1997 labour reforms promoting permanent employment affected establishments’ employment practices. Generally, establishments’ prior employment expectations are realized through changes in all job and worker flows. However, establishments uniquely rely on temporary hires as a buffer to confront diminishing long-run employment expectations. None of the reforms significantly affected establishments’ net temporary or permanent employment flows.http://deepblue.lib.umich.edu/bitstream/2027.42/40032/3/wp646.pd
