Crecimiento endogéno y cambio estructural en un modelo dinámico de insumo-producto

Abstract

THIS PAPER INTRODUCES A SIMPLE DYNAMIC INPUT-OUTPUT MODEL, IN WHICH SOME OF THE MOST IMPORTANT PROPERTIES OF ENDOGENOUS GROWTH THEORY ARE INCLUDED: INNOVATION, KNOWLEDGE SPILLOVERS, VARYING RETURNS TO SCALE AND FULL EMPLOYMENT. THE WISH TO KEEP TH EHYBRID MODEL AS TRACTABLE AS POSSIBLE (DESPITE THE INDUSTRY DETAIL), HAS CAUSED SOME SUBSTANTIAL SIMPLIFICATIONS: CONTRARY TO MOST NEW GROWTH MODELS, THE MODEL LACKS AND EXPLICIT MICROECONOMIC FOUNDATION AND ASSUMES PRODUCTION FUNCTIONS WITH FIXED COEFFICIENTS IN THE SHORT RUN. AFTER THE CONSTITUENT EQUATIONS ARE PRESENTED, THE LONG-RUN BEHAVIOR OF THE MODEL IS STUDIED BY A NUMBER OF COMPUTER SIMULATIONS FOR A HYPOTHETICAL ECONOMY.
