Innovation And Technological Evolution In A Western European Country – The Case Of Portugal


  • Jose Ramos Pires Manso

    (University of Beira Interior)


The paper speaks of the technological evolution using a translog cost function for a western European country – Portugal. It begins by presenting the methodological framework, the estimation process based on the iterative Zellner method to estimate systems of seemingly unrelated regression equations (SURE), the empirical application to Portugal, and the interpretation of the results, namely in terms of the technological evolution.
