Data Envelopment Analysis (DEA) is a linear programming based method for evaluating performance of comparable production units such as firms. Although the method is already extensively applied in many areas of economics, its use in environmental economics and related fields remains limited. The...

PERHAPS, POVERTY AND PLENTY IS THE WORLD'S GREATEST CHALLENGE. THIS STUDY THEREFORE PROPOSE AN APPLIED(COMPUTABLE)GENERAL EQUILIBRIUM APPROACH, THAT IS A RENEW ATTENTION TO THE PROBLEM OF POVERTY , EMPLOYMENT AND INEQUALITY THAT EARLIER STRATEGIES FOCUSING ON RAPID GROWTH WERE UNABLE TO RESOLVE....

In spite of elaborate descriptive and correlational studies, the most ubiquitous phenomenon in economics, namely inflation, has remained unexplained in terms of its mathematical origins. Keynes had attempted to relate inflation to a mechanism of "sticky wages and prices". Hitherto, such theories...

AFRICAN ECONOMIC PERFORMANCE HAS BEEN MARKEDLY WORSE THAN THAT OF OTHER REGIONS. THUS, THE GOVERNMENTS OF AFRICAN COUNTRIES HAVE ASSUMED MAJOR RESPONSIBILITIES FOR ECONOMIC REFORMS AND GROWTH. ALONG WITH THESE RESPONSIBILITIES HAS COME AN INCREASED AWARENESS OF THE INTERRELATEDNESS OF DIFFERENT...

The present paper develops a basic framework for evaluating and optimizing profits in a business operation. In developing a business we are often faced with an infinity of choices ranging from what products or services to sell and what customers to target to how to structure and manage the...

The current population in the World has grown beyond the Break-even level of the food supplies, water, clothing and shelter. Techno- commercial systems are also within the utility of developed nations, but beyond the infrastructure and mental orientation of the Developing and Under Developed...

We consider solutions to general linear dynamic systems, possibly singular and non square with general stability conditions. Besides constructing a general algorytm for finding solutions we provide necessary and sufficient conditions for existence of a solution.

We consider linear dynamic models with rational expectations in case of incomplete and asymmetric information as well as agents heterogeneity. This problem requires solving infinite dimensional matrix equations. We propose asymptotic expansion method to reduce this problem to the finite...

We propose a decomposition method for the solution of a dynamic portfolio optimization problem which fits the formulation of a multistage stochastic programming problem. The method allows to obtain time and nodal decomposition of the problem in its arborescent formulation applying a discrete...
