The Walrasian model has played a central role in all aspects of economics. The purpose of this paper is to propose a general modeling of differential information in the spirit of the Arrow-Debreu model and following the Radner tradition but away from the usual measurability conception. We...

This article analyzes the effect of speculation on the economic welfare from various criteria, using a simple Edgeworth box within a three-period Walrasian competition framework. Here “speculation” is defined as a series of transition processes of each agent’s spontaneous production of...

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...

Many governments use technology incentives as an important component of their greenhouse gas abatement strategies. These “carrots” are intended to encourage the initial diffusion of new, greenhouse-gas-emissions-reducing technologies, in contrast to carbon taxes and emissions trading which...

An allocation's ordinal efficiency deficit (OED) is defined as the greatest ordinal efficiency loss that can result from its application. More precisely, an allocation's OED is the negative of the greatest total amount by which it may be stochastically dominated by another feasible allocation....

This paper gives a proof of the existence of general equilibrium without the use of a fixed point theorem. Unlike other results of this type, the conditions we use do not imply that the set of equilibrium prices is convex. We use an assumption on the excess demand correspondence that is related...

From the set of the first three structural axioms follows the - economic - triangle theorem. It asserts that the product of the three key ratios, which characterize the firm, the market outcome, and the income distribution, is always equal to unity. The theorem contains only unit-free variables,...

Exogenous technical progress can have uneven impacts on productivity contingent on absorptive capacity, structural congruence and trade intensity. The paper illustrates the role of enabling behind-the-border factors for effective absorption and is pertinent for discussing issues like ‘Europe...

A new theory of capitalism is suggested. Its key moments and general logic are presented. This theory is based on the distinction between two market types – the simple commodity market and the capitalist one. Disequilibrium and "imperfect competition" are admitted to be a functional norm of...

The monography considers laws and mechanisms of social development from positions of positivism, dialectic materialism and the theory of systems. The methodology of the author is based on causality in relations of a society and social institutes. Social development is considered as result of...
