Abstract

Country-level census data are typically collected once every 10 years. However, conflict, migration, urbanization, and natural disasters can cause rapid shifts in local population patterns. This study uses Sri Lankan data to demonstrate the feasibility of a bottom-up method that combines household survey data with contemporaneous satellite imagery to track frequent changes in local population density. A Poisson regression model based on indicators derived from satellite data, selected using the least absolute shrinkage and selection operator, accurately predicts village-level population density. The model is estimated in villages sampled in the 2012/13 Household Income and Expenditure Survey to obtain out-of-sample density predictions in the nonsurveyed villages. The predictions approximate the 2012 census density well and are more accurate than other bottom-up studies based on lower-resolution satellite data. The predictions are also more accurate than most publicly available population products, which rely on areal interpolation of census data to redistribute population at the local level. The accuracies are similar when estimated using a random forest model, and when density estimates are expressed in terms of population counts. The collective evidence suggests that combining surveys with satellite data is a cost-effective method to track local population changes at more frequent intervals.

Abstract

Malaysia has been grappling with understanding how many foreign workers reside in the country and thus faces challenges in formulating evidence-based foreign worker policies. This paper uses micro-level remittance transaction data collected from money transfer service providers to estimate the number of foreign workers. Most foreign workers remit a large portion of their earnings to support family members back home. They are low-income earners, sensitive to remittance costs, and opt for money transfer service providers to remit money rather than regular banks, where transfer services are more expensive. Therefore, the remittance data provide a useful source to conduct the investigation. Existing estimates range from two million to five million foreign workers; our results narrow that range to between 2.99 million and 3.16 million foreign workers in Malaysia as of 2017-18. The estimated state and nationality distributions of foreign workers are consistent with the Ministry of Home Affairs data, lending support to the validity of the estimates. Nevertheless, the Bank Negara Malaysia remittance data could potentially underestimate the number of workers in states with low access to money service providers and nationalities that have access to alternative money transfer mechanisms such as commercial banking and informal transfer channels.

Abstract

The Syrian crisis has led to rapid and large-scale population displacement. This paper uses several sources of data, including the United Nations Higher Commissioner for Refugees' registration database and multi-country, multi-topic surveys collected in 2015-16, to characterize service delivery in the context of a rapid influx of displaced populations. The study encompasses infrastructure services, such as electricity and garbage disposal, and social services, such as health and education, and considers both measures of access to services and their perceived quality.

Abstract

This study quantifies the outflow of human capital associated with migration from Guatemala, El Salvador, and Honduras since 1990. To measure the outflow of skills and human capital and how this has changed over time, the study uses information on Northern Triangle migrants residing in the United States, a group that accounts for over 90 percent of all migrants from the three countries. The results suggest that these migrants are, in general, positively selected into migration. That is, based on their observable characteristics, the individuals would have a higher earnings distribution relative to individuals who do not migrate. The results show a decrease in selectivity between the 10-year cohort of migrants who arrived by 2000 and those who arrived by 2014. This finding may reflect increased access to migration networks by lower-income households and individuals. The data suggest that the loss in human capital associated with a 10-year outflow of adults, as measured by foregone local wages, represented 1.9 percent of gross domestic product in El Salvador, 1.5 percent in Honduras, and 1.0 percent in Guatemala.

Abstract

The worsening of Ecuador's socioeconomic conditions and the rapid inflow of Venezuelan migrants demand a rapid government response. Representative information on the migration and host communities is vital for evidence-based policy design. This study presents an innovative methodology based on the use of big data for sampling design of a representative survey of migrants and host communities' populations. This approach tackles the difficulties posed by the lack of information on the total number of Venezuelan migrants-regular and irregular-and their geographical location in the country. The total estimated population represents about 3 percent of the total Ecuadoran population. Venezuelans settled across urban areas, mainly in Quito, Guayaquil, and Manta (Portoviejo). The strategy implemented may be useful in designing similar exercises in countries with limited information (that is, lack of a recent census or migratory registry) and scarce resources for rapidly gathering socioeconomic data on migrants and host communities for policy design.

Abstract

As of 2019, more than 1.2 million Venezuelans passed through Ecuador and more than 400,000 settled (almost 3 percent of Ecuador's population). This paper analyzes the location choices of Venezuelan migrants in Ecuador and the labor market consequences of these choices, using data from Ecuador's labor force survey and mobile phone records on the geographic distribution of Venezuelan migrants. Around half of the migrants live in four cantons (of 221). Their location is primarily driven by local economic conditions, rather than point of entry. Overall, the regions with the largest inflows of Venezuelans have not seen any effects on labor market participation or employment, compared with regions with fewer inflows. However, our difference-in-difference estimates clearly indicate that young, low-educated Ecuadoran workers in high-inflow regions have been adversely affected. Specifically, the estimates that these workers have experienced reductions in employment quality, a 5 percentage-point increase in the rate of informality, and a 13 percentage-point reduction in earnings, relative to workers with similar characteristics living in areas with very low or non-existent inflows of Venezuelans.

Abstract

The Syrian crisis has led to rapid and large-scale population displacement. This paper has two main aims. (i) It documents the size and timing of the Syrian refugee influx into Jordan, Lebanon, and Kurdistan, characterizing the forced nature of displacement and exploring factors that influenced the decision to flee and subsequently move within the host country. (ii) The paper describes the daily living conditions of refugees after displacement, documenting vulnerability along several dimensions, such as housing access and quality, labor market attachment, and financial security. The data sources include the United Nations High Commissioner for Refugees' registration database and multi-country, multi-topic surveys conducted in 2015-16.

Abstract

Ecuador became the third largest receiver of the 4.3 million Venezuelans who left their country in the last five years, hosting around 10 percent of them. Little is known about the characteristics of these migrants and their labor market outcomes. This paper fills this gap by analyzing a new large survey (EPEC). On average, Venezuelan workers are highly skilled and have high rates of employment, compared with Ecuadorans. However, their employment is of much lower quality, characterized by low wages and high rates of informality and temporality. Venezuelans have experienced significant occupational downgrading, relative to their employment prior to emigration. As a result, despite their high educational attainment, Venezuelans primarily compete for jobs with the least skilled and more economically vulnerable Ecuadoran workers. Our simulations suggest that measures that allow Venezuelans to obtain employment that matches their skills, such as facilitating the conversion of education credentials, would increase Ecuador's GDP between 1.6 and 1.9 percent and alleviate the pressure on disadvantaged native workers. We also show that providing work permits to Venezuelan workers would substantially reduce their rates of informality and increase their average earnings.

Abstract

The recent surge in the number of forcibly displaced who cross international borders in search of protection has prompted interest in evaluating policies that achieve the possible "end points" of the phenomenon. As envisaged by United Nations High Commissioner for Refugees (UNHCR), these are the integration in the country of destination, relocation in a third country, and return to the country of origin. The focus of this paper is on the third aspect, namely the appropriate conduct of return policy viewed from the perspective of the host country. More specifically, the main question is whether it is in the economic self-interest of host countries to return forcibly displaced persons. In addressing the question, four ancillary issues are to be addressed: (i) the macroeconomic impact of refugees and of their return; (ii) the labor market impact of refugees and of their return, (iii) the fiscal impact of refugees and of their return; and (iv) how return policy should be formulated and executed. The available evidence and analyses allow this paper's main conclusion, namely that the costs of hosting asylum seekers and refugees are front-loaded, while the benefits accruing from their integration into the labor market and the host economy typically take years to materialize. It follows that from the economic perspective their return after a short stay may represent a costlier option than continuing to invest in their successful integration. Countries with a flexible labor market, strong investment climate, and a welcoming attitude to immigrants tend to see the economic benefits of refugee inflows materialize faster.

Abstract

This open access textbook provides an introduction to theories, concepts and methodological approaches concerning various facets of migration and migration-related diversities. It starts with an introduction to migration studies and continues with an introductory reading of migration drivers, migration infrastructures, migration flows, and several transversal topics such as gender and migration. It also covers politics, policies and governance as well as specific research methods. As an interactive guide, this book develops an innovative format that brings a connection with various online sources. This means that whereas the chapters bring together literature in a coherent way, they are also connected to IMISCOE's online interactive Migration Research Hub for further reading and for more empirical material on migration and diversity. As such, this textbook provides a very useful introductory reading for undergraduate and graduate students as well as for policymakers, policy advisors, and all those interested in studies on migration and migration-related diversities.
