Business groups, which are ubiquitous in emerging market economies, balance the advantages of characteristics such as internal capital markets with the disadvantages such as inefficient internal distribution of resources and suppression of technological and other forms of innovativeness. In this...

This paper presents theory and evidence showing that institutional reforms in developing countries can effectively expand their product varieties in export. Our model demonstrates that relaxing foreign ownership controls and improving contract enforcement can induce multinational companies to...

The firm's stock of human capital is an important determinant of its ability to innovate. As such, any increase in this stock through firm-sponsored training might lead to more innovation. We test this hypothesis using detailed data on firms' human capital investments and innovation performance,...

Die künftige Entwicklung am Arbeitsmarkt ist von drei Megatrends geprägt: Einer Verlagerung unternehmerischer Verantwortung und Risiken auf Arbeitnehmer, steigenden fachlichen Qualifikationsanforderungen und einem drastischen Rückgang des Erwerbspersonenpotentials infolge des demographischen...

We analyse the characteristics of workers who provide work on the basis of a civil or commercial contract, but who are dependent on or integrated into the firm for which they work. We argue that these dependent self-employed lose their rights under labour law, receive less favourable benefits...

We develop a theory of firm scope in which integrating two firms into one facilitates the allocation of resources, but leads to weaker incentives for effort, compared with nonintegration. Our theory makes minimal assumptions about the underlying agency problem. Moreover, the benefits and costs...

The paper analyzes how the choice of organizational structure leads to the best compromise between controlling behavior based on authority rights and minimizing costs for implementing high efforts. Concentrated delegation and hierarchical delegation turn out to be never an optimal compromise. If...

The costs of vertical integration are analyzed within a game-theoretic signaling model. It is shown that a company when being vertically integrated with a supplier may well decide to buy certain components from this supplier even at a lower quality than that offered by external sources. When the...

We develop a product market theory that identifies determinants of worker turnover and explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each others trained employees...

This paper shows that increasing product market competition can have a direct impact on the employment relationship and on wage inequality. I develop a simple model in which an increase in product market competition increases returns to skill through the effect of competition on the sensitivity...
