Based on the current European discussion about immigration policy, this paper gives an overview of central economic consequences of immigration for a host country's labor market. The most important theoretical arguments are presented and evaluated against the available empirical evidence. The...

Economic theory suggests that high-skilled immigration generally has positive effects on the receiving economy. International student mobility is an important channel through which high-skilled immigrants arrive. The purpose of this paper is to identify some of the key determinants of...

We review developments in research on within-country migration, focusing on internal migration in the U.S. We begin by describing approaches to modelling individuals' migration decisions and equilibrium outcomes across local areas. Next, we summarize evidence regarding the impact of migration on...

The H-1B program allows firms in the United States to temporarily hire high-skilled foreign citizens. H-1B workers are highly concentrated among a small number of firms. We develop a theoretical model demonstrating that this phenomenon is an artifact of policy design: When the government...

Diasporas are global communities of migrants who retain a sense of connection with their homeland. The concept is ancient but has only recently become an important area of research in economics. Due to their unique transnational characteristics, diasporas can have significant influence over...

Destination countries can adopt selective immigration policies to improve migrants' quality. Screening potential migrants on the basis of observable characteristics also influences their self-selection on unobservables. We propose a model that analyzes the effects of selective immigration...

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...

We review the growing literature on the political effects of immigration. After a brief summary of the economics of immigration, we turn to the main focus of the paper: how immigrants influence electoral outcomes in receiving countries, and why. We start from the "standard" view that immigration...

This paper explores the relationship of immigrant citizenship ascension and the effect on the naturalized citizen's economic outcomes in Europe and North America. We offer a unique model and empirical outcomes to define optimal waiting periods for immigrant ascension to citizenship by entry...

This chapter reviews and discusses major theories and empirical studies about the welfare magnet hypothesis, i.e. whether immigrants are more likely to move to countries with generous welfare systems. Although economic theory predicts that welfare generosity affects the number, composition and...
