Knowledge that Transforms

ABSTRACT We study the performance of equity mutual funds run by asset management divisions of commercial banking groups using a worldwide sample. We show that bank‐affiliated funds underperform unaffiliated funds by 92 basis points per year. Consistent with conflicts of interest, the underperformance is more pronounced among those affiliated funds that overweight the stock of the bank's lending clients to a great extent. Divestitures of asset management divisions by banking groups support a causal interpretation of the results. Our findings suggest that affiliated fund managers support their lending divisions’ operations to reduce career concerns at the expense of fund investors.

ABSTRACT We develop a model in which financially constrained arbitrageurs exploit price discrepancies across segmented markets. We show that the dynamics of arbitrage capital are self‐correcting: following a shock that depletes capital, returns increase, which allows capital to be gradually replenished. Spreads increase more for trades with volatile fundamentals or more time to convergence. Arbitrageurs cut their positions more in those trades, except when volatility concerns the hedgeable component. Financial constraints yield a positive cross‐sectional relationship between spreads/returns and betas with respect to arbitrage capital. Diversification of arbitrageurs across markets induces contagion, but generally lowers arbitrageurs' risk and price volatility.

ABSTRACT How can fire sales for financial assets happen when the economy contains well‐capitalized but nonspecialist investors? Our explanation combines rational expectations equilibrium and “lemons” models. When specialist (informed) market participants are liquidity‐constrained, prices become less informative. This creates an adverse selection problem, decreasing the supply of high‐quality assets, and lowering valuations by nonspecialist (uninformed) investors, who become unwilling to supply capital to support the price. In normal times, arbitrage capital can “multiply” itself by making uninformed capital function as informed capital, but in a crisis, this stabilizing mechanism fails.

ABSTRACT We investigate a novel determinant of financial distress, namely, individuals' self‐efficacy, or belief that their actions can influence the future. Individuals with high self‐efficacy are more likely to take precautions that mitigate adverse financial shocks. They are subsequently less likely to default on their debt and bill payments, especially after experiencing negative shocks such as job loss or illness. Thus, noncognitive abilities are an important determinant of financial fragility and subjective expectations are an important factor in household financial decisions.

ABSTRACT We investigate whether a model with time‐varying probability of economic disaster can explain prices of collateralized debt obligations. We focus on senior tranches of the CDX, an index of credit default swaps on investment grade firms. These assets do not incur losses until a large fraction of previously stable firms default, and thus are deep out‐of‐the money put options on the overall economy. When calibrated to consumption data and to the equity premium, the model explains the spreads on CDX tranches prior to and during the 2008 to 2009 crisis.

ABSTRACT For years, online retailers have maintained a price advantage over brick‐and‐mortar retailers by not collecting sales tax at the time of sale. Recently, several states have required that online retailer Amazon collect sales tax during checkout. Using transaction‐level data, we document that households living in these states reduced their Amazon purchases by 9.4% following the implementation of the sales tax laws, implying elasticities of –1.2 to –1.4. The effect is stronger for large purchases, where purchases declined by 29.1%, corresponding to an elasticity of –3.9. Studying competitors in the electronics field, we find some evidence of substitution toward competing retailers.
