Foreign direct investment as a long-term capital flow channel: Evidence from Japan

This paper investigates the role of foreign direct investment (FDI) in accounting for the long-term trend of capital flows under demographic changes. For this purpose, we incorporate horizontal FDI under the proximity-concentration trade-off into a two-country DSGE model and conduct a quantitative analysis using long-term Japanese data for capital flows since the 1960s. The quantitative analysis finds that the transition dynamics solely driven by demographic changes well account for the long-term trend of capital flows and that multinational firms’ endogenous decision on FDI in response to population aging is key to explaining the long-term trend.
