The pattern of disagreement between bond raters suggests that banks and insurance firms are inherently more opaque than other types of firms. Moody's and S&P split more often over these financial intermediaries, and the splits are more lopsided, as theory here predicts. Uncertainty over the banks stems from certain assets, loans and trading assets in particular, the risks of which are hard to observe or easy to change. Banks' high leverage, which invites agency problems, compounds the uncertainty over their assets. These findings bear on both the existence and reform of bank regulation.

Using variation in payday lending restrictions over time and across states, we study competition in the market for small, short-term consumer loans. We find that banks and credit unions reduce overdraft credit limits and prices when payday credit, a possible substitute, is prohibited. These findings suggest that depositories respond to payday loan bans by taking less risk, bouncing checks that they would have otherwise covered. The decline in overdraft prices is surprising when viewed in isolation, but sensible given that depositories incur lower credit losses as they limit overdraft coverage. We find some evidence that credit unions’ overdraft activities are more profitable when payday loans are prohibited, consistent with decreased competition. In addition to characterizing the impact of prohibiting payday lending, a common state policy change in recent years, our findings illuminate competition in the small-dollar loan market by highlighting the importance of non-price adjustments to credit offers.
