POPULATION AGEING AND PRICES IN AN OLG MODEL WITH MONEY CREATED BY CREDITS

IGOR FEDOTENKOV

Abstract:

This paper provides an explanation of why population ageing is associated with deflationary processes. For this reason, we create an overlapping-generations model (OLG) with money created by credits (inside money) and intergenerational trade. In other words, we combine a neoclassical OLG model, with post-Keynesian monetary theory. The model links demographic factors, such as fertility rates and longevity, to prices. We show that lower fertility rates lead to a smaller demand for credits, and lower money creation, which causes a decline in prices. Changes in longevity affect prices via real savings and capital market. Furthermore, we address a few links between interest rates and inflation, which arise in the general equilibrium, and are not thoroughly discussed in the literature. Long-run results are derived analytically; short-run dynamics is simulated numerically.

Keywords: Population ageing, inflation, OLG model, inside money, credits.
