Migration & Mobility

Hausmann, R. & Nedelkoska, L., 2017. Welcome Home in a Crisis: Effects of Return Migration on the Non-migrants' Wages and Employment.Abstract

Albanian migrants in Greece were particularly affected by the Greek crisis, which spurred a wave of return migration that increased Albania’s labor force by 5% between 2011 and 2014 alone. We study how this return migration affected the employment chances and earnings of Albanians who never migrated. We find positive effects on the wages of low-skilled non-migrants and overall positive effects on employment. The gains partially offset the sharp drop in remittances in the observed period. The employment gains are concentrated in the agricultural sector, where most return migrants engage in self-employment and entrepreneurship. Businesses run by return migrants seem to pull Albanians from non-participation, self-employment and subsistence agriculture into commercial agriculture.

Hausmann, R., Obach, J. & Santos, M.A., 2016. Special Economic Zones in Panama: A Critical Assessment.Abstract

Special Economic Zones (SEZ) have played an important role in Panama's successful growth story over the previous decade. SEZ have attracted local and foreign investment by leveraging a business-friendly environment of low transaction costs, and created many stable, well-paid jobs for Panamanians. Beyond that, SEZ shall be assessed as place-based policy by their capacity to boost structural transformations, namely attracting new skills and more complex know-how not to be found in the domestic economy.

The aim of this paper is to evaluate the three largest SEZ in Panama:

  • Colon Free Zone
  • Panama-Pacific
  • City of Knowledge

Our results suggest that SEZ have been successful as measured by static indicators, such as foreign investment, job creation and productivity. We also find that SEZ have boosted inflows of high-skill immigrants, who are most likely generating positive knowledge spillovers on Panamanians productivity and wages. However, significant legal instruments and institutional designs are preventing Panama from taking full advantage of the skill variety hosted at the SEZ. Complex immigration processes inhibiting foreigners from transitioning out of the SEZ, a long list of restricted professions and even citizenships considered as a national security concern, are hindering the flow of knowledge, keeping the benefits coming from more complex multinational companies locked inside the gates of SEZ.

Neffke, F., Otto, A. & Weyh, A., 2016. Inter-industry Labor Flows.Abstract

Labor flows across industries reallocate resources and diffuse knowledge among economic activities. However, surprisingly little is known about the structure of such inter-industry flows. How freely do workers switch jobs among industries? Between which pairs of industries do we observe such switches? Do different types of workers have different transition matrices? Do these matrices change over time?

Using German social security data, we generate stylized facts about inter-industry labor mobility and explore its consequences. We find that workers switch industries along tight paths that link industries in a sparse network. This labor-flow network is relatively stable over time, similar for workers in different occupations and wage categories and independent of whether workers move locally or over larger distances. When using these networks to construct inter-industry relatedness measures they prove better predictors of local industry growth rates than co-location or input-based alternatives. However, because industries that exchange much labor typically do not have correlated growth paths, the sparseness of the labor-flow network does not necessarily prevent a smooth reallocation of workers from shrinking to growing industries. To facilitate future research, the inter-industry relatedness matrices we develop are made available as an online appendix to this paper.

Neffke, F., Otto, A. & Hidalgo, C., 2016. The Mobility of Displaced Workers: How the Local Industry Mix Affects Job Search Strategies.Abstract

Establishment closures leave many workers unemployed. Based on employment histories of 20 million German workers, we find that workers often cope with their displacement by moving to different regions and industries. However, which of these coping strategies is chosen depends on the local industry mix. A large local presence of predisplacement or related industries strongly reduces the rate at which workers leave the region. Moreover, our findings suggest that a large local presence of the predisplacement industry induces workers to shift search efforts toward this industry, reducing the spatial scope of search for jobs in alternative industries and vice versa.

Clemens, M., Montenegro, C. & Pritchett, L., 2016. Bounding the Price Equivalent of Migration Barriers.Abstract

Large international differences in the price of labor can be sustained by differences between workers, or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds on the ad valorem equivalent of labor mobility barriers to the United States, with unique nationally-representative microdata on both U.S. immigrant workers and workers in their 42 home countries. The average price equivalent of migration barriers in this setting, for low-skill males, is greater than $13,700 per worker per year. Natural and policy barriers may each create annual global losses of trillions of dollars.

Clemens, M. & Pritchett, L., 2016. The New Economic Case for Migration Restrictions: An Assessment.Abstract

For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country. Recently the literature has taken a new direction by estimating the costs of migration restrictions to global economic efficiency. In contrast, a new strand of research posits that migration restrictions could be not only desirably redistributive, but in fact globally efficient. This is the new economic case for migration restrictions. The case rests on the possibility that without tight restrictions on migration, migrants from poor countries could transmit low productivity (“A” or Total Factor Productivity) to rich countries—offsetting efficiency gains from the spatial reallocation of labor from low to high-productivity places. We provide a novel assessment, proposing a simple model of dynamically efficient migration under productivity transmission and calibrating it with new macro and micro data. In this model, the case for efficiency-enhancing migration barriers rests on three parameters: transmission, the degree to which origin-country total factor productivity is embodied in migrants; assimilation, the degree to which migrants’ productivity determinants become like natives’ over time in the host country; and congestion, the degree to which transmission and assimilation change at higher migrant stocks. On current evidence about the magnitudes of these parameters, dynamically efficient policy would not imply open borders but would imply relaxations on current restrictions. That is, the new efficiency case for some migration restrictions is empirically a case against the stringency of current restrictions.

Hausmann, R. & Neffke, F., 2016. The Workforce of Pioneer Plants.Abstract

Is labor mobility important in technological diffusion? We address this question by asking how plants assemble their workforce if they are industry pioneers in a location. By definition, these plants cannot hire local workers with industry experience. Using German social-security data, we find that such plants recruit workers from related industries from more distant regions and local workers from less-related industries. We also show that pioneers leverage a low-cost advantage in unskilled labor to compete with plants that are located in areas where the industry is more prevalent. Finally, whereas research on German reunification has often focused on the effects of east-west migration, we show that the opposite migration facilitated the industrial diversification of eastern Germany by giving access to experienced workers from western Germany.

Orozco, M., 2015. The Demand for and Supply of Nostalgic Products among the Albanian-Americans: A Survey,Abstract

The U.S. is home to more than 200,000 ethnic Albanians, about half of whom are emigrants from the Republic of Albania. Despite the significant Albanian population in the U.S., official trade of Albanian goods in the U.S. almost does not exist.

We surveyed about 200 Albanian-Americans and several stores offering goods imported from the Balkan region of Europe in three U.S. metropolitan areas with large Albanian population in order to study their purchasing habits. We found that the willingness to purchase products from the region of origin is certainly not matched by an adequate supply. The stores which offer such products are few, often hard to reach and offer limited supplies of a small variety of commodities. In the study, we recommend steps to strengthen the market for nostalgic good through continued market research, trade-related technical assistance, diaspora-donor partnerships for nostalgic trade development and trade fairs.

Coscia, M., Neffke, F. & Lora, E., 2015. Report on the Poblacion Flotante of Bogota.Abstract

In this document we describe the size of the Poblacion Flotante of
Bogota (D.C.). The Poblacion Flotante is composed by people who live
outside Bogota (D.C.), but who rely on the city for performing their job.
We estimate the Poblacion Flotante impact relying on a new data source
provided by telecommunications operators in Colombia, which enables us
to estimate how many people commute daily from every municipality of
Colombia to a specic area of Bogota (D.C.). We estimate that the size of
the Poblacion Flotante could represent a 5.4% increase of Bogota (D.C.)'s
population. During weekdays, the commuters tend to visit the city center

Evidence That Calls-Based and Mobility Networks Are Isomorphic
Coscia, M. & Hausmann, R., 2015. Evidence That Calls-Based and Mobility Networks Are Isomorphic. PLOS One , 10. Publisher's VersionAbstract

Social relations involve both face-to-face interaction as well as telecommunications. We can observe the geography of phone calls and of the mobility of cell phones in space. These two phenomena can be described as networks of connections between different points in space. We use a dataset that includes billions of phone calls made in Colombia during a six-month period. We draw the two networks and find that the call-based network resembles a higher order aggregation of the mobility network and that both are isomorphic except for a higher spatial decay coefficient of the mobility network relative to the call-based network: when we discount distance effects on the call connections with the same decay observed for mobility connections, the two networks are virtually indistinguishable.

Torres, R.C., 2012. Capital and Labor Mobility and the Size of Sub-national Governments: Evidence from a Panel of Mexican States.Abstract

We examine in this paper the relation between government size and capital and labor openness employing a panel of the 32 Mexican states over the period 1996-2006. Making use of two alternative measures of capital and labor openness and employing several alternative econometric specifications, we first find systematic positive effects of our openness measures on the size of the states’ total government spending. Thereafter, we break down total government expenditure and focus on three subcategories of spending associated with social welfare: education, health and poverty alleviation programs. We find that FDI flows, our proxy for capital openness, are not significant determinants of the state’s social spending, but labor openness, in the form of international migration, has a significant and even greater impact on some of the aforementioned categories than on total spending.

Rodríguez-Oreggia, E. & Freije, S., 2012. Long Term Impact of a Cash-Transfers Program on Labor Outcomes of the Rural Youth.Abstract

This paper evaluates if, after ten years of implementation, the conditional cash transfer program Progresa/Oportunidades has had an effect on labor market outcomes among young beneficiaries in rural Mexico. We use a specific module for the young aged 14 to 24 in the 2007 wave of the Rural Households Evaluation Survey and apply a multi-treatment methodology for different time exposition to the program to identify effects on employment probability, wages, migration and intergenerational occupational mobility. Our results show very little evidence of program impacts on employment, wages or inter-generational occupational mobility among the cohort of beneficiaries under study. This suggests that, despite well documented effects on human capital accumulation of the beneficiaries, labor market prospects in the localities under the program remain sparse.
