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...

Fuzzy logic and genetic algorithms are used to rework more realistic (and more complex) models of competitive markets. The resulting equilibria are significantly different from the ones predicted from the usual static analysis; the methodology solves the Walrasian problem of how markets can...

The study of the local characteristics of equilibrium positions generated by the constrained maximization of some criterion functions (such as utility, profit, cost, etc.) goes back to Antonelli's paper [2] of 1886. Certain local properties have been proved to be particularly fruitful for...

I study connected manifolds and prove that a proper map f: M - M is globally invertible when it has a nonvanishing Jacobian and the fundamental group pi (M) is finite. This includes finite and infinite dimensional manifolds. Reciprocally, if pi (M) is infinite, there exist locally invertible...

This paper and appendices report an ongoing study of the interrelationships between technology, income distribution and other socio-economic issues in a long term global context. The present paper therefore describes the work in progress on a project to be completed by July 1980. The aim here is...

This article describes the macroeconomic model used in an ongoing study of technology policies and North-South relations. Other aspects of the study have been described elsewhere [1,2]. We examine here the rationale for the theoretical structure used in the model, the details of the equations,...

The first two sections of the paper are devoted to a combination of Kuznets and structuralist stories, where we ask how the agricultural/nonagricultural terms of trade and income distribution must adjust to permit both savings and investment and commodity market balance to be assured. It will be...

This note provides simple proofs of the equivalence among the core, equilibrium and limited arbitrage in markets with short sales, and with uniform strictly convex preferences.

The paper studies a two-region economy , with two sectors and three factors of production : oil, capital and labor . The South exports oil in exchange for industrial goods from the North . There is a net capital inflow to the South . This equals the difference between its export revenues and...

For any intransitive community preference, we construct a non-convex economy where all the marginal cost pricing general equilibria are Pareto inefficient (theorem 3.2). The result is valid without requiring a fixed income distribution rule (corollary 3.3). Intransitive community preferences are...
