Are Stock Prices Related to Political Uncertainty Index in OECD Countries? Evidence from Bootstrap Panel Causality Test

This study applies bootstrap panel causality, proposed by Kónya (2006), to investigate causal link between political uncertainty and stock price for seven OECD countries over the monthly period of 2001.01 to 2013.04. This modeling approach allows us to examine both the cross-sectional dependency and the country-specific heterogeneity. Our empirical results indicate that not all the countries are alike and that the theoretical prediction that stock prices fall at the announcement of a policy change is not always supported. Specifically, we find evidence of the stock price leading hypothesis for Italy and Spain, while the political uncertainty leading hypothesis cannot be rejected for the United Kingdom and the United States. In addition, the neutrality hypothesis was supported in the remaining three countries (Canada, France, and Germany), while the feedback hypothesis, however, is never found.
