Market imperfections may lead to underinvestment in dynamic general equilibrium models. An interesting but unexplored question is whether policy interventions which attenuate underinvestment gaps necessarily imply that consumption will initially decline. By employing a calibrated version of a...

Incumbent firms have two basic possibilities to improve their competitive position in the product market: Investment in R&D and the creation of entry barriers to the disadvantage of potential rivals, e.g. through lobbying activities, campaign contributions, bribes or the adoption of incompatible...

We investigate the effects of interregional labor market integration in a twosector,overlapping-generations model with land-intensive production in the nontradable goods sector (housing). To capture the response to migration on housing supply, capital formation is endogenous, assuming that firms...

Non-scale R&D-based growth models imply that the decentral and the socially optimal long-run growth rate coincide. Nonetheless, the distortions inherent in a market economy bias both the R&D investment share and the saving rate. As a result, the level of the balanced growth path may differ...

The speed at which an economy converges to its steady state is investigated by using a general non-scale R&D-based growth model. To accomplish this task, an analytical decomposition formula for the instantaneous rate of convergence is developed. By applying this decomposition to the model under...

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...
