In this paper I describe certain results that were obtained in the UNITAR project based on a model I have specified for studying the relationship between international terms of trade and domestic income distributions of the exporting countries within the South. In particular, I shall concentrate...

Oil price behavior has changed dramatically in the last twenty years. These changes can be explained rather simply in terms of the delayed responses of supply and demand to prices, and in terms of changes in the rate of discovery of reserves. This analysis can be used to forecast possible future...

Many of the present difficulties of the world economy have been blamed on the two oil-price explosions of the 1970s. Professor Chichilnisky shows that, at least in the case of the oil-importing developing countries, the negative effects have been overestimated. In fact, in some respects the oil...

We study labor productivity in agriculture within a two-region, two factor and two commodity economy. Increases in productivity can lead to higher or to lower agricultural prices, depending on the internal structure of the economy. We give necessary and sufficient conditions for either outcome;...

In international circles, the concern of the day is the state of the world economy. There is a general appreciation of the severity of the problem, but no widespread agreement about either diagnosis or solutions. We shall focus here on a particular set of topics that have emerged as major issues...

An important problem in environmental economics arises from te irreversibility of consuming or destroying certain resources. Extractive resources like oil are a clear example. Even for environmental resources the same seems to be true in a number of environmental cases, for example biodiversity,...

The paper explores the impacts of resource export policies on major macro variables of the exporter and the importer economies. There are two regions, North and South, trading resources for industrial goods. Each region consumes two goods (basic consumption goods and industrial goods) and...

Regional free trade zones have been unexpectedly successful in the last decade. Since 1980 the European Community enlarged significantly its membership and its scope. It now includes southern European countries, and market-integrating features allowing goods, people, services and capital to flow...

Physical considerations alone cannot explain the volatile behavior of resource prices, or the effects these have on different regions of the world. An optimization analysis may not suffice either, since typically there are several distinct objectives: conservation, cost-minimization, and the...
