Knowledge that Transforms

Using a large sample of U.S. mortgages observed over the 2005–2009 period, we document contagion effects in strategic mortgage defaults. Strategic defaults result from borrowers choosing to exercise their in the money default option and our findings suggest this choice is influenced by the delinquency rate in surrounding zip codes (within a 5 mile radius), after controlling for other known determinants of mortgage default. These controls include a large array of borrower and loan characteristics, local demographic and economic conditions, spatial correlations, and changes in property values. Our findings that the local area delinquency rate is an important factor for strategic defaulters (borrowers that can be influenced in their decision) but not for defaults that are the result of inability to pay (borrowers that had no choice) lend support the contagion hypothesis. Our estimates suggest that a 1% increase in the local area delinquency rate may increase the probability of a strategic default by 7.25–16.5%.

This paper analyzes in an international sample of banks from 104 countries if the sensitivity of the cost of deposits to bank risk varies across banks depending on their systemic and absolute size. We analyze a period before the 2007 financial crisis and control for endogeneity of bank size, intervention policies in past banking crises, and soundness of countries’ public finances. Our results are consistent with the predominance of the too-big-to-fail hypothesis, although this effect is stronger in countries that did not impose losses on depositors in past banking crises and in countries with sounder public finances.

We investigate how banks scrambled for liquidity following the asset-backed commercial paper (ABCP) market freeze of August 2007 and its implications for corporate borrowing. Commercial banks in the United States raised dollar deposits and took advances from Federal Home Loan Banks (FHLBs), while foreign banks had limited access to such alternative dollar funding. Relative to before the ABCP freeze and relative to their non-dollar lending, foreign banks with ABCP exposure charged higher interest rates to corporations for dollar-denominated syndicated loans. The results point to a funding risk manifesting as currency shortages for banks engaged in maturity transformation in foreign countries.

Using a unique dataset of more than 1 million loans made by 296 German banks, we evaluate the impact of many aspects of customer–bank relationships on loan default rates. Our research suggests a practical solution to reducing loan defaults for new customers: Have the customer open a simple transactions account – savings or checking account. Observe for some time and then decide whether to make a loan. Loans made under this model have lower default, as banks can use historical data about their borrowers to establish a baseline against which new client-related information can be evaluated. Banks assemble this historical information through relationships of different forms. We define relationships in many different ways to capture non-credit relationships, transaction accounts, as well as the depth and intensity of relationships, and find each of these can provide information that helps reduce default – even establishing a simple savings or checking account and observing the activity prior to loan granting can help reduce loan defaults. Our results show that banks with relationship-specific information act differently compared with banks that do not have this information both in screening and subsequent monitoring borrowers which helps reduce loan defaults.

Does support to distressed banks early on during financial crises mitigate the macroeconomic consequences of financial distress, and if so does it matter what form the intervention takes? We analyze the effects of government and central bank interventions in 69 systemic banking crises since 1980, of which 29 are part of the recent global financial crisis. Our estimation approach controls for the correlation between intervention measures and the time-invariant component of unobservable crisis severity. We find that timely bank recapitalizations substantially reduce the duration of recessions, underscoring the distortions caused by zombie banks and the costs of regulatory forbearance.

We document strong weekly lead-lag return predictability across stocks from different industries with no customer-supplier linkages (economically unrelated stocks). Between 1980 and 2010, the industry-neutral long-short hedge portfolio earns an average of over 19 basis points per week. This predictability is related to common institutional ownership and is distinct from previously documented lead-lag effects. Common institutional ownership is a complementary rather than a substitute explanation for return predictability. Information linkages are enough to induce return predictability among stocks in the same industry, but economically unrelated stocks exhibit return predictability only when they have common institutional owners. Our findings suggest that institutional portfolio reallocations can induce return predictability among otherwise unrelated stocks.

This paper empirically highlights the role and significance of taxes for the capital structure decisions of banks. Using a difference-in-differences methodology, I show that an increase in the local U.S. state corporate tax rate affects the banks’ financing as well as their operating choices. Better-capitalized banks raise their long-term non-depository debt and thus benefit from an enlarged tax shield. Worse-capitalized banks instead reduce their lending because a higher tax rate increases the tax-adjusted cost of funding, which renders the marginal loan unprofitable.

Extant literature shows that IPO first-day returns are correlated with market returns preceding the issue. We propose a rational explanation for this puzzling predictability by adding a public signal to Benveniste and Spindt (1989)’s information-based framework. A novel result of our model is that the compensation required by investors to truthfully reveal their information decreases with the public signal. This “incentive effect” receives strong empirical support in a sample of 6300 IPOs in 1983–2012. Controlling for the incentive effect, the positive relation between initial returns and pre-issue market returns disappears for top-tier underwriters, where the order book is held to be most informative, effectively resolving the predictability puzzle.

Our study of the corporate loan pricing policies of U.S. banks over the past two decades shows that loan spreads for riskier firms become relatively lower during periods of monetary policy easing compared to tightening. This effect is driven by banks with greater risk appetite, measured from individual banks’ answers to the Senior Loan Officers Opinion Survey. Our results hold with different fixed effects that account for time-varying observed and unobserved heterogeneity of credit demand and bank lending conditions that are not directly related to monetary policy. Together with our survey-based measure of bank risk appetite, we provide compelling evidence of the presence of a bank risk-taking channel of monetary policy in the U.S.

We examine how access to bank credit affects trade credit in the supplier–customer relationships of U.S. public firms. For identification, we use exogenous liquidity shocks to supplier firms in the form of staggered changes to interstate bank branching laws. Using a variety of tests, we show that supplier firms with greater access to banking liquidity offer more trade credit to their customers. We also show that when bank branching restrictions are relaxed in the supplier’s state, the supplier–customer relationship is more likely to survive.
