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 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...

Production often causes pollution as a by-product. Once environmental degra- dation becomes too severe, regulation is introduced by which society forces the economy to make a transition to cleaner production processes. We model this transition as a change in "general purpose technology" and...

The paper first develops a theoretical model with different sectors, each providing a channel for an impact of energy prices on growth. In the short run, growth is hampered by increasing energy prices. In the long run, however, capital accumulation may be crowded out by energy use. This happens...

We augment a Schumpeterian growth model with a public basic-research sector to examine how much a country should invest in basic research. We find that the closer the country is to the world’s technological frontier the more the government should invest in basic research. Basic-research...

We develop a perpetual youth model to investigate how longevity affects economic growth and welfare. Life expectancy is determined by individuals’ investments in healthcare. We find that improvements in the healthcare technology always increase the steady state growth rate. Although the effect...

We study a model where economic growth is fueled by public basic-research investment and the importation of leading technology from foreign countries. In each period, the government chooses the amount of basic research, balancing the cost and benefits of stimulating growth through both channels....

In this paper we study the incentives for basic-research investments by governments in a globalized world. For this purpose, we develop a two-country Schumpeterian growth model in which each country chooses its basic-research investments. We find that a country's basic-research investments...

We study the impact of economic policy on the importance of history and expectations for the macroeconomic performance of an economy. In our model the energy mix is based on the conversion of heterogeneous energy sources. Markups over marginal costs are endogenous so that the marginal revenue...
