We study the optimal R&D trajectory in a setting where new technologiesare never perfect backstops in the sense that there is no perfectlyclean technology that eventually solves the pollution problem once andfor all. New technologies have stings attached, i.e. each emits a specificstock...

Using a panel data set of 361 German corporations for the period 1991 to 1996 we test the hypothesis that firms with more efficient governance structures have higher profitability. To determine efficiency we compare firms with respect to ownership concentration, the identity of owners, capital...

In this paper, we investigate how changes in the skill mix of local labor supply are absorbedby the economy. We distinguish between three adjustment mechanisms: through factorprices, through an expansion in the size of those production units that use the moreabundant skill group more...

This paper presents a framework to analyze the potential changes in transaction costs due to theintroduction of e-commerce on transactions between businesses. It then illustrates and applies thisframework using internal data from an Internet-based firm to measure process improvements,marketplace...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups.Trade induces only firms with high-quality products to export, whereas firms with low-quality products serve only the domestic...

Research and Development (R&D) and innovation are crucial features of the seed industry. To supportlarge R&D investments by the private sector, strong intellectual property rights, such as patents, arenecessary. The exclusivity granted by patents naturally creates market power positions and...

This study explicitly takes into account that the decision to enter into an external R&D relationship is related to an antecedent decision to carry out R&D. This calls for a methodological approach that, at the same time, permits the joint analysis of the determinants of the two decisions and...

The neoclassical model of the production function, as applied by Robert Solow to build the neoclassical model of growth, linked labor and capital to output. More recently, Romer and others have expanded the model to include measures of knowledge capital. In this paper we introduce a new factor,...
