Es wird vielfach vermutet, daß die Software-Industrie von starken Netzwerkeffekten geprägt ist. Doch wie hoch sind die Netzwerkeffekte wirklich? Für die Messung der Netzwerkeffekte bietet sich der hedonische Preisansatz an. Zwei Anwendungen des hedonischen Preisansatzes in der...

This paper analyzes the optimal adjustment strategy of an inventory-holding firm facing price- and quantity-adjustment costs in an inflationary environment. The model nests both the original menu-cost model that allows production to be costlessly adjusted, and the later model that includes...

During the recent decades, multitasking has become a more and more common phenomenon at workplaces. Rather than specializing in a job task, workers perform bundles of tasks. Bundling occurs when tasks are complements. Using individual-level data about job tasks, we analyze which tasks are...

This paper develops a two-tier oligopoly model in which the entry of a multinational firm results in technology transfer to its local suppliers and also impacts the degree of backward linkages in the local industry. The model endogenizes the multinational's choice between anonymous market...

This paper develops two extensions of the dynamic model presented in Melitz (2003). The first extension consists in the introduction of technology choice between three alternative production technologies: L, M and H. L is assumed to be the same as Melitz's single production technology, while M...

Since naturally occurring genetic information serves as a valuable input for biotechnological R&D, the private provision of genetic resources could generate income for the protection of biodiversity-rich areas. However, there has been a controversy over whether these potential revenues are...

We develop an endogenous growth model which is focussed on entrepreneurial skills and their impact on growth and convergence. Our work is closely related to the model by Acemoglu et al. (2006) but extends their analysis in some important respects. Entrepreneurs in our model dispose of two...

Endogeneous growth theory views externalities and particularly externalities associated with knowledge spillovers as the engine of economic growth. In some influential papers (e.g. Glaeser et al. 1992) it is argued that these knowledge spillovers do not transmit costlessly over space. Rather,...

This paper is a tentative summary and appraisal of the main theoretical arguments and empirical evidence for/against an industrial policy in support of high-tech industries. The paper reviews arguments based on endogenous growth theory and strategic trade theory and surveys the most relevant...

This paper deals with the problem of tackling the adverse effect of output growth on environmental quality. For this purpose we use an intermediate sector that builds putty-practically-clay capital consisting of an amalgam of energy and raw capital used for final goods production. The...
