This paper identifies a fundamental challenge in the development of input-output databases of the world economy intended for analysis of alternative scenarios with a model of the world economy. Primary data sources for individual economies generally do not use the same sectoral classification...

Based on C.Bidard’s and E.Klimovsky’s “Switches and Fake switches in methods of production”, an attempt will be made to show if fake switch points (as named) are in fact, and opposite of what Bidard and Klimovsky claim, real switch points.

This paper deals with the problem of choosing techniques. When we refer to the problem of choosing techniques, we actually refer to choose from a set of given production processes-techniques -according to a specific criterion- the optimum one. The criteria which are going to be presented are the...

The share of knowledge-intensive services and products in total output and demand and in the production of advanced, but also less advanced or emerging economies, has steadily increased over time and especially so for the knowledge-intensive services. This 'quaternization' of the economies not...

The future evolution of energy supply technologies strongly depends on (and affects) the economic and environmental systems, due to the high dependency of this sector on the availability and cost of fossil fuels, especially on the small regional scale. This paper aims at presenting the modeling...

This paper develops a methodology to predict and to thus possibly mitigate the economic impacts of major catastrophes, such as earthquakes and tsunamis. The short-run impacts are assumed to be determined by the attempts of economic actors to return to the pre-catastrophe economic situation as...

There are some specific features of the non-radial DEA (data envelopment analysis) models which cause some problems under the returns to scale measurement. In the scientific literature on DEA, some methods were suggested to deal with the returns to scale measurement in the non-radial DEA models....

Applications of the DEA models show that inadequate results may arise in some cases, two of these inadequacies being: a) too many efficient units may appear in some DEA models; b) a DEA model may show an inefficient unit from the point of view of experts as an efficient one. The purpose of this...
