    Abstract: Although the scarcity of accurate and accessible data on international migration flows typically prevents a full understanding of migratory patterns, this might not be the case for Latin America, where high-quality census data on migrant flows is publicly available through the project International Migration in Latina America (IMILA). However, such data has mostly been used for research at the regional level because of the fragmented nature of their availability and the lack of English documentation. To tackle this issue, we consolidated data from the IMILA collection to provide a harmonized dataset with five-year flows by country of birth, sex, and age group, for 19 countries of destination and five census waves. Moreover, comparing IMILA to other two available data sources on flows to Latin America, we showed that IMILA provides a more accurate assessment of migration flows from North America and Europe, enables a better quantification of minor migration flows, and enhances the visibility of female migration.

    Abstract: Extreme weather events such as hurricanes are growing in frequency and magnitude and are expected to affect a growing population due to migration patterns, ecosystem alteration, and climate. While all victims of natural disasters face common challenges, displaced populations undergo distinct experiences that are specific to their relocation. However, measuring the mortality consequences of disasters among these populations is inherently challenging due to the displacement that can take place before, during or in the aftermath of an event. We use an interrupted time-series design to analyze all-cause mortality of Puerto Ricans in the U.S. to determine death occurrences of Puerto Ricans on the mainland U.S. following the arrival of Hurricane Maria in Puerto Rico in September 2017. Hispanic Origin data from the National Vital Statistics System and from the Public Use Microdata Sample of the American Community Survey are used to estimate monthly origin-specific mortality rates for the period 2012 to 2018. We estimated log-linear regressions of monthly deaths of persons of Puerto Rican vs. other Hispanic groups by age group, gender, and educational attainment. We found an increase in mortality for persons of Puerto Rican origin during the 6-month period following the Hurricane (October 2017 through March 2018), suggesting that deaths among these persons were 3·7% (95% CI: 0·025-0·049) higher than would have otherwise been expected. In absolute terms, we estimated 514 excess deaths (95% CI 346 – 681) of persons of Puerto Rican origin that occurred on the mainland U.S., concentrated in those aged 65 years or older. Our findings suggest an undercounting of previous deaths as a result of the hurricane due to the systematic effects on the displaced and resident population in the mainland U.S. Displaced populations are frequently overlooked in disaster relief and subsequent research. Ignoring these populations provides an incomplete understanding of the damages and loss of life.

  3. By: Wukuang Cun; M. Hashem Pesaran
    Abstract: This paper develops and solves a spatiotemporal equilibrium model in which regional wages and house prices are determined jointly with location-to-location migration flows. The agent’s optimal location choice and the resultant migration process are shown to be Markovian, with the transition probabilities across all location pairs given as non-linear functions of wage and housing cost differentials, endogenously responding to migration flows. The model can be used for the analysis of spatial distribution of population, income, and house prices, as well as for the analysis of the entire dynamic process of shock spill-over effects in regional economies through location-to-location migration. The model is estimated on a panel of 48 mainland U.S. states and the District of Columbia over the training sample (1976-1999) and is shown to fit the data well over the evaluation sample (2000-2014). The estimated model is then used to analyse the size and speed of spatial spill-over effects by computing spatiotemporal impulse responses of positive productivity and land-supply shocks to California, Texas, and Florida. The sensitivity of the results to migration elasticity, housing depreciation rate and local land supply conditions is also investigated.

    Abstract: The Gambella Region is one of the marginalised and most conflict-ridden regions in Ethiopia. Recently, violent clashes between the two largest ethnic groups in the region - the host communities, the Anywaa, and the South Sudanese Nuer refugees - have reignited the debate on refugee integration in the region. In fact, the roots of the Anywaa-Nuer conflict can be traced back to the imperial regime of Ethiopia at the end of the 19th century. In the early 1960s however, the arrival and spontaneous integration of Nuer refugees was peaceful and relations between both ethnic groups were harmonious. During this time, refugee management was organised locally. Against this background, the focus of the present paper is to understand the nature, context and evolution of the long-standing conflict between the Anywaa and refugees from the Nuer ethnic group in the Gambella Region. Beyond that, the paper explores the Anywaa-Nuer conflict within the context of the political power dynamics of the last two decades. Thereby, the paper reveals that the disputes between the Anywaa and the Nuer have taken on a new dimension since the early 1990s.

    Abstract: Regulatory agencies overseeing the labor market often rely on worker complaints to direct their enforcement. However, if workers face differential barriers to complain, this system could result in ineffective targeting and create disparities in working conditions. To investigate these implications, we examine how the onset of Secure Communities—a localized immigration enforcement program—affected occupational safety and health. Counties’ participation in Secure Communities substantially reduced complaints to government safety regulators, but increased injuries, at workplaces with Hispanic workers. We show that these effects are most consistent with employers reducing safety inputs in response to workers’ decreased willingness to complain.

    Abstract: This paper studies the economic and political effects of a large trade shock in agriculture - the grain invasion from the Americas - in Prussia during the first globalisation (1871-1913). We show that this shock accelerated the structural change in the Prussian economy through migration of workers to booming cities. In contrast to studies using today's data, we do not observe declining per capita income and political polarisation in counties affected by foreign competition. Our results suggest that the negative and persistent effects of trade shocks we see today are not a universal feature of globalisation, but depend on labour mobility. For our analysis, we digitise data from Prussian industrial and agricultural censuses on the county level and combine it with national trade data at the product level. We exploit the cross-regional variation in cultivated crops within Prussia and instrument with Italian trade data to isolate exogenous variation.
