Knowledge that Transforms

We present evidence that the Federal Reserve stress tests produce information about both the stress-tested bank holding companies and the overall state of the banking industry. Our evidence goes beyond a standard event study, which cannot differentiate between small abnormal returns and large, but opposite-signed, abnormal stock returns. We find that stress test disclosures are associated with significantly higher absolute abnormal returns, as well as higher abnormal trading volume. More levered and riskier holding companies seem to be more affected by the stress test information. We find no evidence that stress test disclosures have reduced the production of private information. After disclosure begins, stress tested firms attract equity analysts without changing analysts’ forecast dispersions or their mean forecast error.

Using a unique dataset we provide new evidence on the significant penalty on client fund performance due to conflicts of interest related to the cross trading (TCT) activities of mutual fund advisers: funds managed by advisers in the top TCT quintile significantly underperform funds managed by advisers in the bottom TCT quintile by 1% per year. Adviser incentives to engage in cross trading are directly related to their opportunities for generating revenues from affiliated trading operations. Additional tests suggest that the significantly higher trading commissions paid by client funds of high-TCT advisers are a major source of their under-performance.

I study credit rationing in small firm-bank relationships by using a unique data set of matched loan applications and contracts. I establish the degree of credit rationing by relating a firm's requested loan amount to the bank's granted amount. In line with theoretical predictions, credit rationing is higher for opaque than transparent firms at the beginning of their bank relationships and decreases over time for both. After testing for several alternative explanations, the results suggest that information and incentive problems explain the observed credit rationing and its dynamics.

Homestead exemptions to personal bankruptcy allow households to retain their home equity up to a limit determined at the state level. Households that may experience bankruptcy thus have an incentive to bias their portfolios toward home equity. Using US household data for the period 1996–2006, we find that household demand for real estate is relatively high if the marginal investment in home equity is covered by the exemption. The home equity bias is more pronounced for younger and less healthy households that face more financial uncertainty and therefore have a higher ex ante probability of bankruptcy. These results suggest that homestead exemptions have an important bearing on the portfolio allocations of US households and the extent to which they insure against bad shocks.

This paper investigates the impact of ample liquidity provision by the European Central Bank on the functioning of the overnight unsecured interbank market from 2008 to 2014. We use novel data on interbank transactions derived from TARGET2, the main euro area payment system. To identify exogenous shocks to central bank liquidity, we exploit the timing of ECB liquidity operations and use a simple structural vector auto-regression framework. We argue that the ECB acted as a de facto lender-of-last-resort to the euro area banking system and identify two main effects of central bank liquidity provision on interbank markets. First, central bank liquidity replaces the demand for liquidity in the interbank market, especially during the financial crisis (2008–2010). Second, it increases the supply of liquidity in the interbank market in stressed countries (Greece, Italy and Spain) during the sovereign debt crisis (2011–2013).

This paper develops a theory of how risk is assessed and priced through the business cycle by developing an intuitive model in which there is uncertainty about whether outcomes depend on the risk-management skills of banks or are just based on luck, in the spirit of Piketty’s (1995) model of “left-wing” and “right-wing” dynasties. Periods of sustained banking profitability cause all agents to rationally elevate their estimates of bankers’ skills, despite the uncertainty about what is driving outcomes. Everybody consequently becomes sanguine about bank risk, credit spreads decline, and banks choose increasingly risky assets. Conditional on subsequently observing unexpectedly high defaults, beliefs can endogenously shift to put more weight on outcomes being luck-driven, and this causes credit spreads to widen and may be enough to trigger a crisis. Regulatory implications of the analysis are extracted.

We investigate Project Finance as a private response to inefficiencies created by weak legal protection of outside investors. We offer a new illustration that law matters by demonstrating that for large investment projects, Project Finance provides a contractual and organizational substitute for investor protection laws. Project Finance accomplishes this by making cash flows verifiable through two mechanisms: (i) contractual arrangements made possible by structuring the project within a single, discrete entity legally separate from the sponsor; and (ii) private enforcement of these contracts through a network of project accounts that ensures lender control of project cash flows. Comparing bank loans for Project Finance with regular corporate loans for large investments, we show that Project Finance is more likely in countries with weaker laws against insider stealing and weaker creditor rights in bankruptcy. We identify the predicted effects using difference-in-difference and triple-difference tests that exploit exogenous country-level legal changes and inter-industry differences in free cash flow and tangibility of assets.

We consider a model in which the threat of bank liquidations by creditors as well as equity-based compensation incentives both discipline bankers, but with different consequences. Greater use of equity leads to lower ex-ante bank liquidity, whereas greater use of debt leads to a higher probability of inefficient bank liquidation. The bank's privately-optimal capital structure trades off these two costs. With uncertainty about aggregate risk, bank creditors learn from other banks’ liquidation decisions. Such inference can lead to contagious liquidations, some of which are inefficient; this is a negative externality that is ignored in privately-optimal bank capital structures. Thus, under plausible conditions, banks choose excessive leverage relative to the socially optimal level, providing a rationale for bank capital regulation. While a blanket regulatory forbearance policy can eliminate contagion, it also eliminates all market discipline. However, a regulator generating its own information about aggregate risk, rather than relying on market signals, can restore efficiency and market discipline by intervening selectively.

Using data from the Italian Credit Register we identify the adverse effect of the freeze of the securitization market on bank lending during the crisis of 2007–2008. Applying a differences-in-differences estimation to data on firms that borrow from multiple banks, we single out credit supply by including firm fixed effects. Our results show that the degree to which banks tightened credit supply to nonfinancial firms is positively related to the share of loans they securitized before the crisis. The tightening translated into lower credit growth, higher interest rates, lower probability of accepting loan applications and higher probability of relationship termination. Firms were unable to fully compensate the negative credit supply shock, which suggests that the securitization freeze played a role in reducing aggregate credit availability.

Different modes of external finance provide heterogeneous benefits for the borrowing firms. Informal finance offers informational advantages whereas formal finance is scalable. Using unique survey data from China, we find that informal finance is associated with higher sales growth for small firms but lower sales growth for large firms. We identify a complementary effect between informal and formal finance for the sales growth of small firms, but not for large firms. Co-funding, thereby simultaneously using the informational advantage of informal finance and the scalability of formal finance, is therefore the optimal choice for small firms.
