We adopt a general equilibrium approach in order to measure the effects of recent immigration on the Western German labour market, looking at both wage and employment effects. Using the Regional File of the IAB Employment Subsample for the period 1987-2001, we find that the substantial...

We study how the city system is affected by the possibility for the members of the same cultural diaspora to interact across different cities. In so doing, we propose a simple two-city model with two mobile cultural groups. A localized externality fosters the productivity of individuals when...

We propose an endogenous growth model with offshoring to investigate its effects on product innovation and growth in the country of origin. Offshoring is associated with reduced feedback from offshored plants to domestic labs as well as coordination problems between the offshored and domestic...

We develop a multi-country Dixit-Stiglitz model to investigate the impacts of: (i) changes in the international distribution of consumers' expenditure; (ii) decreasing tariffs; and (iii) improvements in transportation infrastructure. We show that, in general, decreasing tariff barriers do not...

We distill the main insights from recent trade models on firms' responses to globalisation. Our primary aim is to assess the economic impact and the welfare implications of the resulting reallocation of resources across firms and countries. In so doing, we bring theory into life through the...
