We examine how equity mispricing affects corporate investment in an international setting. We find that investment is more sensitive to stock prices for equity-dependent firms than for non-equity-dependent firms in our international sample. Investment is also more sensitive to stock prices for firms located in countries with more developed capital markets (i.e., lower costs of raising capital), higher share turnover (i.e., shorter shareholder horizons), and higher R&D intensity (i.e., more opaque assets). More importantly, the positive relation between equity dependence and the sensitivity of investment to stock prices is more pronounced for firms located in these same countries. These findings are consistent with the equity-financing hypothesis and the catering hypothesis on corporate investment proposed by Baker et al. (2003) and Polk and Sapienza (2009), respectively.

Models of political risk predict that increases in political uncertainty cause stock prices to fall, especially for politically sensitive firms. We use the event of the Bo Xilai political scandal in 2012 in China as an exogenous shock to identify the impact of political uncertainty on asset prices. We document that the Bo scandal caused a significant drop in stock prices, especially for firms that are more politically sensitive. Further analysis shows that the stock price drop is mainly driven by a change in discount rate, providing strong support for the existence of priced political risk.

Based on a difference-in-differences approach, we find strong evidence that the initial enforcement of insider trading laws improves capital allocation efficiency. The effect is concentrated in developed markets and manifests shortly after the enforcement year. Further analysis shows that the improvement is positively associated with the increase in liquidity around the enforcement year and the opaqueness of the information environment before the enforcement year. The improvement is more pronounced for firms operating in more competitive markets, being more financially constrained, and with more severe agency problems. Finally, we find increased accounting performance after the enforcement and the increase is positively associated with the improvement in capital allocation efficiency. Overall, our evidence suggests that the initial enforcement of insider trading laws improves capital allocation efficiency by providing more information to guide managerial decisions and by reducing market frictions arising from information asymmetry and agency problems.
