We examine how the threat of exit by non‐blockholders (investors with ownership <5%) relates to firms' income smoothing. Unlike informed blockholders, non‐blockholders lack private information and therefore rely more on reported accounting numbers to evaluate firm performance. To isolate the exit threat, we use the unique setting in Japan where strong firm‐centric social norms and lack of insider access lead non‐blockholding foreign institutions to influence management primarily through the threat of exit. We predict and find that foreign non‐blockholders' exit threat is positively associated with the extent of income smoothing. This effect is more pronounced for firms less embedded in Japan's stakeholder‐based system, firms with greater stock liquidity, and firms with higher US institutional ownership. In addition, smoothing associated with such an exit threat, on average, is informative. Our findings suggest that Japanese firms under non‐blockholders' exit threat increase income smoothing to reduce perceived uncertainty and that such smoothing generally meets non‐blockholders' information needs.

Using an international sample of IPO firms from 36 countries and a country-level index for societal trust, we find strong evidence that societal trust is negatively associated with the degree of IPO underpricing. In cross-sectional analyses, we find that the effect of societal trust in reducing IPO underpricing is more pronounced when the information environment is less transparent, when the stock market environment is less robust, and when legal institutions are weaker, settings where the effect of trust is likely to be more salient. Our study contributes to and extends the literature by providing strong evidence that an informal institution such as societal trust has an important and consistent influence on international IPO underpricing.
