Market reactions to non-fundamental news (or no-news) reverse for extreme firm information environments. A one percentage increase in intangible returns for small firms (large firms) lead to a 2.33% decrease (0.70% increase) in monthly returns over the next 12months. The results are robust to firm characteristics adjustments, alternative measures of firm information environment and private information, idiosyncratic risk, and microstructure effects. The results are consistent with the cross-sectional findings of confirmation bias, where investors show stronger bias when the information environment is rich. We derive a model with confirmation bias that further explains the cross-sectional momentum pattern for the majority of firms in the market.

Based on the Merton (1977) put option framework, we develop a deposit insurance pricing model that incorporates asset correlations, a measurement for the systematic risk of a bank, to account for the risk of joint bank failures. Estimates from our model suggest that actuarially fair risk-based deposit insurance that considers only individual bank failure risk is underpriced, leaving insurance providers exposed to net losses. Our estimates also capture the size premium where big banks are priced with higher deposit insurance than small banks. This result is particularly relevant to the current regulatory concerns on big banks that are too-big-to-fail. Above all, our approach provides a unifying framework for integrating risk-based deposit insurance with risk-based Basel capital requirements.
