ENDOGENOUS GROWTH AND ENDOGENOUS BUSINESS CYCLES

Abstract

This paper presents a computable general equilibrium model of endogenous (stochastic) growth and cycles that can account for two key features of the aggregate data: balanced growth in the long-run and business cycles in the short-run. The model is built on Schumpeter's idea that economic development is the consequence of the periodic arrival of innovations. There is growth because each subsequent innovation leads to a permanent improvement in the production technology. Cycles arise because innovations trigger a re-allocation of resources between production and R&D. The quantitative implications of the calibrated version of our model are very similar to those of Kydland and Prescott's (1982) model. Moreover, our model can correct two serious shortcomings of RBC models: it can account for the persistence in output growth and the asymmetry of growth within the business cycle.endogenous growth, endogenous business cycles, innovation, R&D
