ABSTRACT

The paper focuses on two countries, Japan and the U.S., to test the integration of capital markets. In Japan, the enactment of the Foreign Exchange and Foreign Trade Control Law in December of 1980 amounted to a true regime switch that virtually eliminated capital controls. Using multifactor asset pricing models, we show that the price of risk in the U.S. and Japanese stock markets was different before, but not after, the liberalization. This evidence supports the view that governments are the source of international capital market segmentation.
