Does the mere presence of big banks affect macroeconomic outcomes? Gabaix (2011) shows that idosyncratic shocks can have aggregate effects if the distribution of firm sizes in manufacturing follows a power law distribution. Our contribution is two-fold. First, we expand the theory of granularity...

Moderne Evaluationsmethoden auf der Basis ökonometrischer Verfahren und randomisierter Feldexperimente machen es für immer mehr Politikbereiche möglich, die Wirksamkeit wirtschaftspolitischer Maßnahmen zu überprüfen. Gleichwohl sind diese Methoden in der deutschen Evaluationspraxis nicht...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

Foreign bank entry is frequently associated with spillover effects for local banks and increasing competition in the local banking market. We study the impact of these effects on host countries. In particular, we ask how these effects interact and how they depend on the competitive environment...

This paper investigates how multinational firms choose their capital structure in response to political risk. We focus on two choice variables, the leverage and the ownership structure of the foreign affiliate, and we distinguish different types of political risk, like expropriation, corruption...

We develop a model in which multinational investors decide about the modes of organization, the locations of production, and the markets to be served. Foreign investments are driven by market-seeking and cost-reducing motives. We further assume that investors face costs of control that vary...

It is often argued that multinationals are reluctant to transfer technology due to the fear of spillovers. We show that this need not be the case if host country policies like taxation are taken into account. Furthermore, we examine the incentives the multinational and the host country have to...

In this paper we analyze the conditions under which a foreign direct investment (FDI) involves a net capital flow across countries. Frequently, foreign direct investment is financed in the host country without an international capital movement. We develop a model in which the optimal choice of...
