Using business survey data on German manufacturing firms, this paper provides tests for hypotheses formulated in capital market imperfection theories that predict distributional effects in the transmission of monetary policy. The business conditions of small firms are found to be somewhat more...

The idea of an industrial policy that promotes large businesses—heavyweights—as the best way to compete in a globalized world has become, again, en vogue among European politicians. The only apparent controversy about the idea revolves around whether it is better to promote national...

A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct frms, which...

This paper develops a model with multiple market locations in which the quality of intangible assets of firms, provided by management, determines the firms. performance. Despite an ex ante symmetry of potential entrants, the equilibrium assignment of heterogeneous managerial skills to firms...
