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...

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...

The paper develops a model with non-exponential population growth, nonrenewable natural resources, and endogenous knowledge creation to analyse substitution between primary inputs and an essential use of resources in the innovation sectors, which is generally considered as most unfavourable for...

We analyze an economy in which sectors are heterogeneous with respect to the intensity of natural resource use. Long-term dynamics are driven by resource prices, sectoral composition, and directed technical change. We study the balanced growth path and determine stability conditions. Technical...

Since 1980, the aggregate income of oil-exporting countries relative to that of oil- poor countries has been remarkably constant despite structural gaps in productivity growth rates. This stylized fact is analyzed in a two-country model where resource- poor (Home) and resource-rich (Foreign)...

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....
