Predmet príspevku:  Seminar centra pre ekonomiu a financie 25.11.2009 
Vazeni kolegovia, pozyvame Vas na seminar Centra pre ekonomiu a financie Fakulty matematiky, fyziky a informatiky Univerzity Komenskeho. Jeho obsahom bude prednaska Mikulas Luptacik (Vienna University of Economics and Business): Efficiency Analysis of a Multisectoral Economic System, ktora sa uskutocni v stredu 25.11.2009 o 15:00 hod. v poslucharni C na FMFI UK. Abstrakt prednasky: In the literature two approaches of productivity and efficiency analysis can be found, namely the neoclassical approach and a frontier approach known as data envelopment analysis (DEA). Under the neoclassical approach we refer to the seminal paper by DEBREU (1951), measuring the efficiency of the economy by a coefficient of resource utilization and to the books by ten RAA (1995) and (2005). DEA approach allows decomposing productivity growth into a movement of the economy towards the frontier and a shift of the latter. The neoclassical approach imputes productivity growth to factors, but cannot distinguish a movement towards the frontier and a movement of the frontier. In the paper by ten RAAMOHNEN (2002) a synthesis of both approaches is provided. The problem addressed in the present paper is concerned with efficiency analysis applied to a single economy represented by the Leontief inputoutputmodel extended by the constraints for primary factors. First, the efficiency frontier is generated using a multiobjective optimization model instead of having to use data from different decision making units. The solutions of the multiobjective optimization problems define efficient virtual decision making units (DMUs). The efficiency of the given economy is defined as the difference between the potential of an economy and its actual performance and can be obtained as a solution of a DEA model. It can be shown that the solution of the above defined DEA model yields the same efficiency score and the same shadow prices as the models by ten RAA (1995), (2005), despite the different variables used in both models. Using duality theory of linear programming the equivalence of the approaches permits a clear economic interpretation.
