Product-Variety, Population, Competition, and Growth

Abstract

This paper analyzes how population and product market competition (PMC) interact with each other in affecting productivity growth. We find that only a fully endogenous growth model with purposeful investment in human capital, an input in the production of intermediate goods, can simultaneously predict (as suggested by the available theoretical/empirical literature) that the relationships between population and economic growth rates and between PMC and economic growth are non-monotonic. The trade-off between specialization-gains and complexity-costs arising from an expansion of product-variety is crucial in determining the sign of these correlations, and the possible complementarity between two key variables in economic growth.
