"We use a search and matching model to investigate the economic relationship between training and local economic conditions. We identify two aspects of this relationship going in opposite directions: on the one hand, the complementarity between local knowledge spillovers and training generates a...

In this paper we study the dynamics of local employment growth in West Germany from 1980 to 2001. Using dynamic panel techniques, we analyse the timing of the impact of diversity and specialisation, as well as of the human capital structure of local industries. Diversity has a positive effect on...

This paper analyses the impact of dynamic MAR- and Jacobs-externalities on local employment growth in Germany between 1993 and 2001. In order to facilitate a comparison between the neighbouring countries we firstly replicate the study of Combes (2000) on local employment growth in France and...

Using a unique dataset on worldwide multinational corporations with precise location of headquarters and affiliates, I present evidence of a trade-off between distance to the headquarters and the knowledge intensity of the foreign subsidiary's economic activity, emerging from dynamics related to...

Firms exhibit heterogeneity in size, productivity, and internal structure, and this is true even within the same industry. It has been thought since the time of Adam Smith that a firm's internal structure affects its productivity through the channel of gains from specialization. Our paper...

We examine a situation where efforts on different tasks positively affect production but are not separately verifiable and where the manager (principal) and the worker (agent) have different ideas about how production should be carried out: agents prefer a less efficient way of production. We...

The model developed in this paper explains differences in the division of labour across firms as a result of computer technology adoption. We find that changes in the division of labour can result both from reduced production time and from improved communication possibilities. The first shifts...

We model the sorting of medical students across medical occupations and identify a mechanism that explains the possibility of differential productivity across occupations. The model combines moral hazard and matching of physicians and occupations with pre-matching investments. In equilibrium...

Relationships have changed dramatically in the last fifty years. Fewer couples are marrying, more are cohabiting. Reasons for this shift abound, but the shift may have consequences of its own. A number of models predict that those cohabiting will specialize less than those marrying. Panel data...

This paper studies the impact of international business trips on the stock of knowledge available to an economy. It develops a theoretical model to analyse the possible effects, and presents an empirical application using productivity data for a panel of twelve Australian industries during...
