We study properties of the solutions to a parametrized constrained optimization problem in Hilbert spaces. A special operator is studied which is of importance in economic theory; sufficient conditions are given for its existence, symmetry, and negative semidefiniteness. The techniques used are...

This article outlines work in progress on a study of technological choice in the context of North-South development. Its main purpose is to describe the methodology being developed in the pilot phase of the study. This is of interest because it links together a number of analytic...

Global modeling has evolved remarkably in the last two decades. Such evolution led it to perform today's role as an experimental laboratory for the social sciences, and particularly for applications to policy planning. Two of the most interesting applications to policy are to resource economics...

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...

Our concern in this paper is to analyze the optimal long-run pricing policies of oil-exporting countries. These might be described briefly as the policies which best meet their objectives, subject to the various limitations imposed on them by the realities of world economic forces.

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...

This chapter presents a summary of recent results obtained in game and social choice theories, and highlights the application and the development of tools in algebraic topology. The purpose is expository: no attempt is made to provide complete proofs, for which references are given, nor to...

Although American business leaders do not like protectionism, more and more of them are concluding that too many countries are stacking the deck against American competitors. The severe recession of 1980-83 and its lingering effects in certain regions and business sectors; unemployment stuck at...
