Ownership as a determining factor in the evolution of efficiency
Taking into consideration the privatisation policy that has emerged in recent decades, significant researches have been carried out to compare the efficiency of public and private companies. However, there is a drop regarding the evolution of these companies over the years. In view of this, the present research tries to deal with the analysis of efficiency from a dynamic perspective, and to evaluate the process of changes occurring between the starting point (1990) and the finishing point (1998). The methodology is Indexes of Malmquist. Empirical data show that privatised enterprises have improved its technical efficiency more than private enterprises. Public enterprises are the firms that have improved least in this way. Finally a complementary analysis considers if determinant factors, such exports, R&D., presence of workers contracted, or human c Indexepital contribute to improve the efficiency.
