| Outline of Final Research Achievements |
In standard neoclassical growth models, the process of economic growth is represented by the increase in the production of homogenous final goods. However, the real economy is not homogeneous but rather consists of heterogeneous goods, technologies, and production factors. Thus, this research project aimed to build a set of growth theories that endogenously explain various shifts in the composition of a heterogeneous economy through economic growth; e.g., the shift of demand from older goods to newer goods, the shift of production firms from older technologies to newer technologies, and the shift of the use of production factors from mostly unskilled workers to more skilled ones. This research project analyzed how these shifts occur and their effects on the measured rate of economic growth in the SNA, as well as the effects on the welfare of consumers.
