The problems about diversity concern various themes. We will show that the economic theory can contribute by itself to the debate in progress. It could seem paradoxical, but what is called the “dismal science” can serve to attenuate some pessimistic attitudes, putting in prominence a...

Nowadays, a process can be observed in Germany where electricity producing and trading firms react to the electricity market liberalisation by merging market shares, since the year 2000, which reduces the number of suppliers and influences production and consumer prices. This paper discusses...

We develop a dynamic discrete choice model of a self-interested and unchecked ruler making decisions regarding the exploitation of a resource-rich country. This dictator makes the recursive choice between either investing domestically to live off the productivity of the country while facing the...

We present a theory of spatial development. A continuum of locations in a geographic area choose each period how much to innovate (if at all) in manufacturing and services. Locations can trade subject to transport costs and technology diffuses spatially across locations. The result is an...

Is tourism an opportunity for lagging countries in the elusive quest for growth (Easterly, 2002)? Recent empirical evidence suggests that the answer is a cautious yes. Aggregate cross-country data show that tourism specialization is likely to be associated with higher per capita GDP growth rates...

In this paper we use the hybrid integrated model WITCH to quantify and analyze the investments and financial flows stimulated by a climate policy to stabilize Greenhouse Gases concentrations at 550ppm CO2-eq at the end of the century. We focus on investments to decarbonize the power sector and...

We investigate the relationship between diversity and productivity in Europe using an original dataset covering the NUTS 3 regions of 12 countries of the EU15 (Austria, Belgium, Denmark, France, former Western Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Sweden and the United...

Specializing in tourism is an option available to a number of less developed countries and regions. But is it a good option? To answer this question, we have compared the relative growth performance of 14 “tourism countries” within a sample of 143 countries, observed during the period...

In the current age of trade and financial openness, local economies in developing countries are becoming increasingly exposed to external investments. The objective of the proposed two-sector model with environmental externalities is to provide an insight into the interaction between external...

In this paper we study the problem of exhaustible resources and renewable resources in a theoretical endogenous growth framework, under various assumptions. In particular, we consider the hypotheses that those two inputs are or are not technologically perfect substitutes of each other. Moreover,...
