The Feldstein-Horioka puzzle in South American countries:a time-varying approach

Inasmuch as the investment-savings correlation is related to capital immobility and each country has specific and time-varying capital account liberalization and financial deregulation processes, we might not expect a constant and identical correlation for a group of countries. We performed both a constant (OLS) and a time-varying (Kalman filter) estimation of the investment-savings coefficient for Argentina, Brazil and Chile. As expected, the time-varying model presented a better fit, but our findings suggested that the investment-savings correlation is a misleading measure of capital mobility.
