In this chapter, we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that...

We study how the skill distribution in an economy responds to changes in wage gaps induced by trade integration. Using administrative data for Denmark (1993-2012), we conduct a two-step empirical analysis. In the first step, we predict changes in wage gaps that are triggered by exogenous trade...

We study the gains from trade in an economy with oligopolistic competition, firm heterogeneity, and innovation. Oligopolistic competition together with free entry make markups responsive to firm productivity and trade costs. Lowering trade costs reduces markups on domestic sales but increases...

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation, and provide a formula to decompose the mechanism. The new insight we provide is that market concentration can be a welfare-relevant feature of market power above and beyond markup...

Building on the task-based approach of technological change, this paper discusses the interaction between occupational polarization (e.g. a gradual increase of native employment in the lowest and highest-paying jobs) and employment opportunities of immigrant workers. Using high quality...

An important goal of immigration policy is to facilitate the entry of foreignborn workers whose skills are in short supply in national labor markets. In recent decades, information and communication technology [ICT] has fueled the demand for highly educated workers at the expense of lower...

An important goal of immigration policy is facilitating the entry and supply of workers whose skills are scarce in national labour markets. In recent decades, the introduction of information and communication technology [ICT] fuelled the demand for highly skilled workers at the expense of lower...

We study the impact of rising robot exposure on the careers of individual manufacturing workers, and the equilibrium impact across industries and local labor markets in Germany. We find no evidence that robots cause total job losses, but they do affect the composition of aggregate employment....

The aim of this paper is to formalise a two-country model of trade liberalisation and technical change with heterogenous firms and search-and-matching frictions in the labour market. By considering different sectors and factors of production we allow for comparative advantages and study the...

In recent years, Germany and other European countries face the strongest immigration flow in their history. Experts unanimously agree that one of the core factors of a successful social integration is the labor market participation of the new arrivals. This paper investigates the impact of...
