Abstract or Table of Contents

Population aging challenges the financing of social security systems in developed economies, as the fraction of the population in working age declines. The resulting pressure on capital-labor ratios translates into a pressure on factor prices and production. While European countries all face this challenge, the speed at which their population ages differs, and thus the pressure on capital-labor ratios. If capital markets are integrated, differences in population aging may lead to cross-country spillovers, as investors freely seek the best returns on capital. Using a multi-country overlapping-generations model covering 14 European Union countries, I quantify spillovers and find that capital market integration leads to redistribution across countries over the long run. For instance, GDP per capita would on average be 2.9 %-points lower in Germany in each of the next 50 years if capital markets were perfectly integrated and increases in labor income taxes maintained public debt constant, compared to a closed economy case; by contrast, GDP per capita would on average be 2.1 %-points higher in France, whose population ages slower than in Germany. I also show that pension reforms can change the cross-country redistribution patterns, some countries losing from capital market integration without the reform but winning with it. The research has policy and methodological implications.
