Two major trends in the world economy are international migration and environmental degradation. The object of the paper is to analyze the connection between these two trends, which have generally been analyzed in isolation. Here we represent a world economy in which the exploitation of natural...

We study the problem of finding necessary and sufficient conditions that guarantee global uniqueness of equilibria in a pure exchange economy. We show that for every economy to have a unique equilibrium it is necessary and sufficient that (i) there are no critical economies and (ii) a compact...

В данной статье рассмотрена проблема самоорганизации экономических процессов в условиях совершенной конкуренции, основанной на взаимодействии индивидуальных...

We construct an index theorem for smooth infinite economies with separable utilities that shows that generically the number of equilbria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.

This paper examines the conceptual framework upon which José Valenzuela Feijóo unfolds a theory of value. The elementary form of value gives way to pairs of commodities which in spite of being ordinary, each is to function as money. The general economic equilibrium becomes a means to replace...

This paper deals with generic determinacy of equilibria for infinite dimensional consumption spaces. Our work could be seen as an infinite-dimensional analogue of Dierker and Dierker (1972), by characterising equilibria of an economy as a zero of the aggregate excess demand, and studying its...

Batabyal and Beladi (2019) have recently analyzed a model of competition between two cities that use a local public good (LPG) to attract members of the creative class. The creative class consists of artists and engineers and they study the behavior of a representative artist and an engineer. In...

In this paper we propose the following conjecture: the equilibrium manifold E(r) ⊂ RLM−1, where L is the number of goods and M the number of consumers, is a minimal submanifold if and only if the price is unique for every economy. We show the validity of this conjecture for an arbitrary...

In this paper we find a geometrical characterization of some components of the theory of equilibrium Walrasian and the existence of these in a pure exchange economy with heterogeneous agents where there are r goods and m agents. It will be proven that this economics admit stratification, for...

This article discusses the association of income and happiness. The basic data consist of statements by individuals on their subjective happiness, as reported in thirty surveys from 1946 through 1970, covering nineteen countries, including eleven in Asia, Africa, and Latin America. Within...
