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...

Recent influential empirical work has emphasized the negative impact immigrants have on the wages of US-born workers, arguing that immigration harms less educated American workers in particular and all US-born workers in general. Because US and foreign born workers belong to different skill...

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...

This paper estimates the effects of immigration on wages of native workers at the national U.S. level. Following Borjas (2003) we focus on national labor markets for workers of different skills and we enrich his methodology and refine previous estimates. We emphasize that a production function...

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...

This Paper studies the positive aspects of destination vs. origin principles of commodity taxation as well as tax harmonization, with an emphasis on the international implications of these measures when firms are mobile. We investigate the tax incidence of these two principles on price levels...

This paper describes the possible impact of multi-speed integration on the location of economic activities in Europe. We present a model where two countries integrate their economies and leave a third temporarily outside because of its lower income. We analyse the effect of different integration...

The effects of the quality of institutions on economic development and comparative advantage have been so far investigated separately. This paper proposes a theoretical framework in which trade patterns and growth rates are jointly determined by international differences in contract enforcement...

Increasing returns in matching between skilled workers and firms create a local thick-market externality when labour markets are geographically segmented. This generates an agglomeration force that can offset the dispersion force due to local competition in a segmented product market. When this...
