      內 容:Using a representative sample of 25 countries, we analyze the nonlinear relationship between oil price uncertainty and stock market returns by the panel smooth transition (PSTR) model. We find that oil price uncertainty has a negative and significant effect on stock returns, and this negative effect increases with economic policy uncertainty; that is, oil price fluctuations exert a stronger impact on stock returns for countries with higher economic policy uncertainty. Nevertheless, there is huge heterogeneity in responses, with oil exporting countries whose economies depend more on oil price responding strongly to oil price uncertainty, and oil importing countries driving a drop in responses. In addition, oil price uncertainty has a greater impact on the stock markets of developing countries. Also, we find that oil price uncertainty is associated with a larger decrease in stock returns during the financial crisis.
