In the presence of increasing specialization of workers it becomes more and more difficult for firms to find the most suitable workers. In such an environment a multinational corporation has an advantage because it can exchange workers between plants in different countries. In this way it can...

We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

When the world economy was recently hit by a severe recession, governments all over the world reacted by initiating stimulus packages. Some countries (among them, most notably, China and the US) tried to put special emphasis on their home industries by including "Buy local'' clauses into the...

Why are empirically observed tariffs so much lower than theoretically calculated Nash-equilibrium tariffs? We argue that this gap can be narrowed by using a dynamic model instead of a static model. This approach has two advantages. (i) It allows us to take account of the transitional process...

Recently, the world economy has seen its greatest down turn since World War II. Although not as bad as during the Great Depression, there was still a worrisome increase in protectionist measures, in an attempt to mitigate the economic downturn. Protectionism can have many different faces. It can...

We introduce search and matching unemployment into a model of trade with differentiated goods and heterogeneous firms. Countries may differ with respect to size, geographical location, and labor market institutions. Contrary to the literature, our single-sector perspective pays special attention...

A large class of models with CES utility and iceberg trade costs are now known to generate isomorphic “gravity equations.” Economic interpretations of these gravity equations vary in terms of two basic elements: the exporter's “mass” variable and the elasticity of trade with respect to...

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodríguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

In this paper, we provide causal evidence that firms serve new markets which are geographically close to their prior export destinations with a higher probability than standard gravity models predict. We quantify the impact of this spatial pattern using a data set of Chinese firms which had...
