POSSIBILITIES OF MODELING COMPETITIVENESS INDICES RELEVANCY

Measurement of competitiveness is – even in a well-defined conceptual frame – more a compromise between available data and the big number of different criteria and objectives. Additionally, in the building of competitiveness indices, many technical problems occur that have not always a unique not ambiguous solution, even theoretically. For measurement information relevancy of competitiveness indices, in this work we purpose an original econometric model relied on subtle sets. After a short qualitative and quantitative study of information relevancy, it was showed that there is a synergy of information relevancy of economic concepts and, therefore, this is applied also over the concept of competitiveness. Basic idea of purposed model was that the variables (determinants) of competitiveness indices could be the pieces of a subtle set. The program realized for implementation of purposed model accompanied by a database having necessary variables for competitiveness indices, showed that information relevancy is useful in management decisions and can be a real working instrument.
