We develop a theory of income and payout smoothing by firms when insiders know more about income than outside shareholders, but property rights ensure that outsiders can enforce a fair payout. Insiders set payout to meet outsiders' expectations and underproduce to manage future expectations downward. The observed income and payout process are smooth and adjust partially and over time in response to economic shocks. The smaller the inside ownership, the more severe underproduction is, resulting in an "outside equity Laffer curve."

We show that eurozone bank risks during 2007–2013 can be understood as carry trade behavior. Bank equity returns load positively on peripheral (Greece, Italy, Ireland, Portugal, Spain, or GIIPS) bond returns and negatively on German government bond returns, which generated carry until the deteriorating GIIPS bond returns adversely affected bank balance sheets. We find support for risk-shifting and regulatory arbitrage motives at banks in that carry trade behavior is stronger for large banks and banks with low capital ratios and high risk-weighted assets. We also find evidence for home bias and moral suasion in the subsample of GIIPS banks.

We develop a theory of optimal bank leverage in which the benefit of debt in inducing loan monitoring is balanced against the benefit of equity in attenuating risk shifting. However, faced with socially costly correlated bank failures, regulators bail out creditors. Anticipation of this generates multiple equilibria, including one with systemic risk in which banks use excessive leverage to fund correlated, inefficiently risky loans. Limiting leverage and resolving both moral hazards—insufficient loan monitoring and asset substitution—requires a novel two-tiered capital requirement, including a “special capital account” that is unavailable to creditors upon failure.

Can banks maintain their advantage as liquidity providers when exposed to a financial crisis? While banks honored credit lines drawn by firms during the 2007 to 2009 crisis, this liquidity provision was only possible because of explicit, large support from the government and government‐sponsored agencies. At the onset of the crisis, aggregate deposit inflows into banks weakened and their loan‐to‐deposit shortfalls widened. These patterns were pronounced at banks with greater undrawn commitments. Such banks sought to attract deposits by offering higher rates, but the resulting private funding was insufficient to cover shortfalls and they reduced new credit.
