The aim of this dissertation is to enhance understanding of the measurement, drivers, and consequences of international migration from an economic perspective. To achieve this aim, the dissertation focuses on three objectives, which will be addressed in four distinct studies (read: chapters). These studies are conducted or are built on theory-based, empirical research using econometric and experimental methods.The first objective, relating to the measurement of migration, is to outline the advantages and disadvantages of different ways of measuring international migration flows. This objective is addressed in Chapter 2, which empirically evaluates the differences between various measures of migration used by economists and demographers.The second objective, relating to the drivers of migration, is to describe which factors explain the size and direction of international migration flows. This objective is addressed in Chapters 2 and 3, in which I quantify the influence that country-level factors have on migration.Although the analysis in Chapter 2 is primarily concerned with the performance of different migration measures, it nevertheless touches on "traditional" drivers of migration, such as migration networks, destination country income, and distance between countries. In contrast, Chapter 3 focuses exclusively on cultural similarity between countries as a facilitating factor of international migration.The third objective, relating to the consequences of migration, is to characterize the impact that migration or migration-related phenomena have on the economic outcomes of those affected. This objective is addressed in chapters 4 and 5, which highlight two separate aspects of migration outcomes. Chapter 4 investigates the effects of negative stereotypes and shows that young migrants are more susceptible to confirm negative stereotypes than non-migrants.Chapter 5 reviews the role of remittances on the economic development of origin countries.In addition to the above, this thesis showcases the broad methodological toolbox of migration economists. As economic migration research spreads over many related fields, e.g., development economics, labor economics, international economics, and economic demography, to name a few, researchers must make use of the methods in these fields and keep up with recent methodological developments. For example, Chapter 3 brings state-of-the-art practices from the trade gravity literature to migration, and the study in Chapter 4 uses, in an innovative way, a so-called information provision experiment to study the role of negative stereotypes.Before describing the contents of this thesis in more detail (Section 4), the following provides background information on current migration trends as well as the standard theory of 8 So, over time, more and more elements of the original Sjaastad model have been refined and endogenized (e.g., Bodvarsson, Simpson, and Sparber 2015). Notable additions are the Roy-Borjas selection model, credit and poverty constraints, endogenous wages, human capital ac...
