A rolling test of Granger causality between the Finnish and Japanese security markets

In the paper we test the impact of the Japanese stock market on two financial asset groups, free and restricted shares, on the Finnish market in the early 90s. The causality is tested in the Granger sense. The research issue is particularly interesting, since the restrictions on foreign ownership were abolished by the end of 1992. The linkage between the Japanese and Finnish financial economies is seen to be stronger for free shares than for restricted. In particular, significant Granger causality between Japanese and Finnish free shares is observed at relatively long consecutive time intervals, whereas the Japanese impact on the restricted shares is only occasional. Thus, the decision to abolish the restrictions not only leads to increased international dependence in the future, but will also change the risk profile of the restricted shares. Key words - Granger causality, international asset pricing, restricted vs free shares
