Abstract: We study innovation and the resulting Schumpeterian economic growth that this innovation gives rise to in a model with N heterogeneous regions. For each region i where i = 1,…,N, our analysis leads to six findings. First, we define the balanced growth path (BGP) allocations and the equilibrium of interest. Second, we stipulate the form of the innovation possibilities frontier that is consistent with balanced economic growth. Third, we derive the growth rate of the ith region in the decentralized equilibrium. Fourth, we solve the social planner’s problem and derive the Pareto optimal growth rate in the ith region. Fifth, we compare the two preceding growth rates and then discuss the circumstances in which there is either too much or too little innovation in (i) the ith region, (ii) an aggregate economy of N>2 regions and (iii) an aggregate economy of N=2 regions. Sixth, we briefly discuss interregional trade and its effects in an aggregate economy of N=2 regions. Finally, we conclude and then offer suggestions for extending the research described here.
