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...

This paper argues that growth theory needs a more general “regularity” concept than that of exponential growth. This opens up for considering a richer set of parameter combinations than in standard growth models. Allowing zero population growth in the Jones (1995) model serves as our...

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...

A general growth model with explicit resource reallocation costs is set up. A new feature is the property of hysteresis (i.e. a continuum of stationary equilibria) in closed-economy growth models. Employing a linear model the hysteresis range and the consequences for the long-run growth rate are...

Integration a.ects 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...

We propose the relaxation algorithm as a simple and powerful method for simulating the transition process in growth models. This method has a number of important advantages: (1) It can easily deal with a wide range of dynamic systems including multi-dimensional systems with stable eigenvalues...

We set up a dynamic stochastic model of a stylized economy comprising a final output sector (with traditional and modern firms) and an intermediate goods sector. It is shown that market integration reduces the volatility of the rate of return of capital invested in modern firms. The induced...

We set up a simple dynamic macroeconomic model with (i) polluting consump- tion and a preference for a clean environment, (ii) increasing returns in abate- ment giving rise to an EKC and (iii) sustained growth resulting from a linear final-output technology. The model captures two sorts of...
