In macroeconomic dynamic models the speed at which output converges to its steady state is of outstanding interest. Theoretical investigations usually focus on the asymptotic speed of convergence only. This procedure is, however, unnecessarily restrictive and hides important information. The...

Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...

Motivated by the process of economic development in Eastern Germany since the German reunification we set up a dynamic macroeconomic model of a small open economy where both capital and labor are mobile and there are increasing returns to scale at the aggregate level. The model features multiple...

In the first era of financial globalization (1880-1914), global capital market integration led to substantial net capital movements from rich to poor economies. The historical experience stands in contrast to the contemporary globalization where gross capital mobility is equally high, but did...

This short paper presents a simple analytical stability proof for the well-known Segerstrom (1998) model of endogenous growth. Moreover, a calibrated version of the model is employed to assess the speed of convergence. The result shows that transitional dynamics are important and, hence, the...

Integration affects economic growth mainly through two different channels: The scale-effect channel and the factor-reallocation channel. In order to investigate both channels within a unifying framework, we employ a simple descriptive growth model. The scale-effect channel increases either the...

The expected growth rate of a stochastic Ak-economy under Poisson uncertainty is derived. The differences and similarities of economic growth under Wiener and Poisson uncertainty are discussed. To understand the uncertainty-growth nexus, the (implicit) risk premium under Poisson uncertainty is...

The market solution of a general R&D-based endogenous growth model is developed. The model is general in two respects: First, general formulations are used and restrictions are only introduced provided that these become necessary. Second, each factor of production (labour, capital and...
