Debt Flexibility
How flexible are corporate loans after origination? Theory predicts coordination problems should make syndicated loans harder to modify than single-bank loans. We show the opposite. Using comprehensive regulatory data, we document that syndicated loans are modified frequently and respond to borrower distress, while single-lender loans are half as likely to be modified. This gap is not explained by covenants or performance pricing. Instead, syndicated loans are monitored more intensively. We show theoretically and empirically how fixed monitoring costs generate scale economies: larger loans ...

Animal spirits and business cycles
Animal spirits are often suggested as a cause of business cycles, but they are very difficult to define. Recent research proposes a novel explanation based on the changing level of risk over time and people?s uncertainty about how the world works. The interaction of these two can lead to significant business cycle fluctuations in response to spikes in volatility. This finding gives researchers an alternative to irrational behavior as an explanation for why swings in consumer sentiment appear to drive the business cycle.

Debt Flexibility
This paper documents new facts on the modification of bank loans using FR Y-14Q regulatory data on C&I loans. We find that loan-level modifications of key contractual terms, such as interest and maturity, occur at least once for 41% of loans. Cross sectional differences in modifications are substantial and amplified by borrower distress. Relative to single-lender loans, syndicated loans are 1.5 times more likely to be modified and interest rate changes are twice as likely. Our findings call into question whether 1) creditor dispersion makes loan modifications more challenging and 2) ...

Long-Run Risk is the Worst-Case Scenario: Ambiguity Aversion and Non-Parametric Estimation of the Endowment Process
We study an agent who is unsure of the dynamics of consumption growth. She estimates her consumption process non-parametrically to place minimal restrictions on dynamics. We analytically show that the worst-case model that she uses for pricing, given a penalty on deviations from the point estimate, is a model with long-run risks. This result cannot in general be matched in a fixed model with only parameter uncertainty. With a single parameter determining risk preferences, the model generates high and volatile risk premia and matches R2s from return forecasting regressions, even though risk ...
