Necessary and Sufficient Conditions for Existence and Uniqueness of Recursive Utilities
Published: 1/25/2020 | DOI: 10.1111/jofi.12877
JAROSLAV BOROVIČKA, JOHN STACHURSKI
We obtain exact necessary and sufficient conditions for existence and uniqueness of solutions of a class of homothetic recursive utility models postulated by Epstein and Zin. The conditions center on a single test value with a natural economic interpretation. The test sheds light on the relationship between valuation of cash flows, impatience, risk adjustment, and intertemporal substitution of consumption. We propose two methods to compute the test value when an analytical solution is not available. We further provide several applications.
Taming the Factor Zoo: A Test of New Factors

We propose a model selection method to systematically evaluate the contribution to asset pricing of any new factor, above and beyond what a high‐dimensional set of existing factors explains. Our methodology accounts for model selection mistakes that produce a bias due to omitted variables, unlike standard approaches that assume perfect variable selection. We apply our procedure to a set of factors recently discovered in the literature. While most of these new factors are shown to be redundant relative to the existing factors, a few have statistically significant explanatory power beyond the hundreds of factors proposed in the past.
High‐Frequency Trading and Market Performance
Published: 1/23/2020 | DOI: 10.1111/jofi.12882
MARKUS BALDAUF, JOSHUA MOLLNER
We study the consequences of, and potential policy responses to, high‐frequency trading (HFT) via the tradeoff between liquidity and information production. Faster speeds facilitate HFT, with consequences for this tradeoff: information production decreases because informed traders have less time to trade before HFTs react, but liquidity (measured by the bid‐ask spread) improves because informational asymmetries decline. HFT also pushes outcomes inside the frontier of this tradeoff. However, outcomes can be restored to the frontier by replacing the limit order book with one of two alternative mechanisms: delaying all orders except cancellations or implementing frequent batch auctions.

We examine the relation between insiders’ investment horizon and the information content of their trades with respect to future stock returns. We conjecture that an insider's investment horizon establishes a benchmark for expected patterns of continued trading behavior and thus helps identify unexpected insider trades, which should be more informative in efficient markets. Consistent with this conjecture, the trades of short‐horizon insiders are both more unexpected and more informed, on average, than those of long‐horizon insiders. Short‐horizon insiders and their firms also tend to display characteristics that are associated with a greater focus on short‐termism.
Can Unemployment Insurance Spur Entrepreneurial Activity? Evidence From France
Published: 1/22/2020 | DOI: 10.1111/jofi.12880
JOHAN HOMBERT, ANTOINETTE SCHOAR, DAVID SRAER, DAVID THESMAR
We evaluate the effect of downside insurance on self‐employment. We exploit a large scale reform of French unemployment benefits which insured unemployed workers starting businesses. The reform significantly increased firm creation without decreasing the quality of new entrants. Firms started post‐reform were initially smaller, but their employment growth, productivity, and survival rates are similar to those pre‐reform. New entrepreneurs' characteristics and expectations are also similar. Finally, jobs created by new entrants crowd out employment in incumbent firms almost one‐for‐one, but have a higher productivity than incumbents. These results highlight the benefits of encouraging experimentation by lowering barriers to entry.
Shorting in Speculative Markets
Published: 1/22/2020 | DOI: 10.1111/jofi.12871
MARCEL NUTZ, JOSÉ A. SCHEINKMAN
In models of trading with heterogeneous beliefs following Harrison–Kreps, short‐selling is prohibited and agents face constant marginal costs‐of‐carry. The resale option guarantees that prices exceed buy‐and‐hold prices and the difference is identified as a bubble. We propose a model where risk‐neutral agents face asymmetric increasing marginal costs on long and short positions. Here, agents also value an option to delay, and a Hamilton–Jacobi–Bellman equation quantifies the influence of costs on prices. An unexpected decrease in shorting costs may deflate a bubble, linking financial innovations that facilitated shorting of MBSs to the collapse of prices.

We decompose the returns of five well‐known anomalies into cash flow and discount rate news. Common patterns emerge across the five factor portfolios and their mean‐variance efficient (MVE) combination. Whereas discount rate news predominates in market returns, systematic cash flow news drives the returns of anomaly portfolios and their MVE combination with the market portfolio. Anomaly cash flow and discount rate shocks are largely uncorrelated with market cash flow and discount rate shocks and with business cycle fluctuations. These rich empirical patterns restrict the joint dynamics of firm cash flows and the pricing kernel, thereby informing models of stocks' expected returns.
Consumption Fluctuations and Expected Returns
Published: 1/6/2020 | DOI: 10.1111/jofi.12870
VICTORIA ATANASOV, STIG V. MØLLER, RICHARD PRIESTLEY
This paper introduces a novel consumption‐based variable, cyclical consumption, and examines its predictive properties for stock returns. Future expected stock returns are high (low) when aggregate consumption falls (rises) relative to its trend and marginal utility from current consumption is high (low). We show that the empirical evidence ties consumption decisions of agents to time variation in returns in a manner consistent with asset pricing models based on external habit formation. The predictive power of cyclical consumption is not confined to bad times and subsumes the predictability of many popular forecasting variables.
Relationship Trading in Over‐the‐Counter Markets
Published: 12/22/2019 | DOI: 10.1111/jofi.12864
TERRENCE HENDERSHOTT, DAN LI, DMITRY LIVDAN, NORMAN SCHÜRHOFF
We examine the network of trading relationships between insurers and dealers in the over‐the‐counter (OTC) corporate bond market. Regulatory data show that one‐third of insurers use a single dealer, whereas other insurers have large dealer networks. Execution prices are nonmonotone in network size, initially declining with more dealers but increasing once networks exceed 20 dealers. A model of decentralized trade in which insurers trade off the benefits of repeat business and faster execution quantitatively fits the distribution of insurers' network size and explains the price–network size relationship. Counterfactual analysis shows that regulations to unbundle trade and nontrade services can decrease welfare.
Securitization, Ratings, and Credit Supply
Published: 12/20/2019 | DOI: 10.1111/jofi.12866
BRENDAN DALEY, BRETT GREEN, VICTORIA VANASCO
We develop a framework to explore the effect of credit ratings on loan origination. We show that ratings endogenously shift the economy from a signaling equilibrium, in which banks inefficiently retain loans to signal quality, toward an originate‐to‐distribute equilibrium with zero retention and inefficiently low lending standards. Ratings increase overall efficiency, provided that the reduction in costly retention more than compensates for the origination of some negative net present value loans. We study how banks' ability to screen loans affects these predictions and use the model to analyze commonly proposed policies such as mandatory “skin in the game.”
Beyond Random Assignment: Credible Inference and Extrapolation in Dynamic Economies
Published: 12/19/2019 | DOI: 10.1111/jofi.12862
CHRISTOPHER A. HENNESSY, ILYA A. STREBULAEV
We derive analytical relationships between shock responses and theory‐implied causal effects (comparative statics) in dynamic settings with linear profits and linear‐quadratic stock accumulation costs. For permanent profitability shocks, responses can have incorrect signs, undershoot, or overshoot depending on the size and sign of realized changes. For profitability shocks that are i.i.d., uniformly distributed, binary, or unanticipated and temporary, there is attenuation bias, which exceeds 50% under plausible parameterizations. We derive a novel sufficient condition for profitability shock responses to equal causal effects: martingale profitability. We establish a battery of sufficient conditions for correct sign estimation, including stochastic monotonicity. Simple extrapolation/error correction formulas are presented.
What Is a Patent Worth? Evidence from the U.S. Patent “Lottery”

We provide evidence on the value of patents to startups by leveraging the quasi‐random assignment of applications to examiners with different propensities to grant patents. Using unique data on all first‐time applications filed at the U.S. Patent Office since 2001, we find that startups that win the patent “lottery” by drawing lenient examiners have, on average, 55% higher employment growth and 80% higher sales growth five years later. Patent winners also pursue more, and higher quality, follow‐on innovation. Winning a first patent boosts a startup’s subsequent growth and innovation by facilitating access to funding from venture capitalists, banks, and public investors.
Risk Management in Financial Institutions

ADRIANO A. RAMPINI, S. VISWANATHAN, GUILLAUME VUILLEMEY
We study risk management in financial institutions using data on hedging of interest rate and foreign exchange risk. We find strong evidence that institutions with higher net worth hedge more, controlling for risk exposures, across institutions and within institutions over time. For identification, we exploit net worth shocks resulting from loan losses due to declines in house prices. Institutions that sustain such shocks reduce hedging significantly relative to otherwise‐similar institutions. The reduction in hedging is differentially larger among institutions with high real estate exposure. The evidence is consistent with the theory that financial constraints impede both financing and hedging.

Credit supply expansion can affect an economy by increasing productive capacity or by boosting household demand. In this study, we develop a test to determine if the household demand channel is present, and we implement the test using both a natural experiment in the U.S. in the 1980s and an international panel of 56 countries over the last several decades. Consistent with the importance of the household demand channel, we find that credit supply expansion boosts nontradable sector employment and the price of nontradable goods, with limited effects on tradable sector employment. Such credit expansions amplify the business cycle and lead to more severe recessions.
Glued to the TV Distracted Noise Traders and Stock Market Liquidity
Published: 11/18/2019 | DOI: 10.1111/jofi.12863
JOEL PERESS, DANIEL SCHMIDT
In this paper we study the impact of noise traders’ limited attention on financial markets. Specifically we exploit episodes of sensational news (exogenous to the market) that distract noise traders. We find that on “distraction days,” trading activity, liquidity, and volatility decrease, and prices reverse less among stocks owned predominantly by noise traders. These outcomes contrast sharply with those due to the inattention of informed speculators and market makers, and are consistent with noise traders mitigating adverse selection risk. We discuss the evolution of these outcomes over time and the role of technological changes.
Informed Trading and Intertemporal Substitution
Published: 11/13/2019 | DOI: 10.1111/jofi.12857
YIZHOU XIAO
I examine the possibility of information‐based trading in a multiperiod consumption setting. I develop a necessary and sufficient condition for trade to occur. Intertemporal substitution introduces a desire to correlate current consumption with future aggregate shocks. When agents have heterogeneous time‐inseparable preferences, information differentially affects relative preferences for current and future consumption, making information‐based trading mutually acceptable. The no‐trade result continues to hold if there is no aggregate shock, or if agents have either homogeneous or time‐separable preferences.
Tax‐Efficient Asset Management: Evidence from Equity Mutual Funds
Published: 11/12/2019 | DOI: 10.1111/jofi.12843
CLEMENS SIALM, HANJIANG ZHANG
We investigate the relation between tax burdens and mutual fund performance from both a theoretical and an empirical perspective. The theoretical model introduces heterogeneous tax clienteles in an environment with decreasing returns to scale and shows that the equilibrium performance of mutual funds depends on the size of the tax clienteles. Our empirical results show that the performance of U.S. equity mutual funds is related to their tax burdens. We find that tax‐efficient funds exhibit not only superior after‐tax performance, but also superior before‐tax performance due to lower trading costs, favorable style exposures, and better selectivity.
Measuring Innovation and Product Differentiation: Evidence from Mutual Funds
Published: 11/12/2019 | DOI: 10.1111/jofi.12853
LEONARD KOSTOVETSKY, JEROLD B. WARNER
We study innovation and product differentiation using a uniqueness measure based on textual analysis of prospectuses. We find that small and start‐up families have higher start rates than larger families, and their products are more unique. Unique strategies attract more inflows in the first three years, and investors respond more to text‐based uniqueness than other measures such as holdings or returns uniqueness. For established funds, word uniqueness has weak negative power for explaining returns, so investors in competitive equilibrium do not sacrifice much performance to get specialized products. Uniqueness attenuates the flow‐performance relation, reducing the risk of investor outflows.
The Market for Conflicted Advice
Published: 11/8/2019 | DOI: 10.1111/jofi.12848
BRIANA CHANG, MARTIN SZYDLOWSKI
We present a model of the market for advice in which advisers have conflicts of interest and compete for heterogeneous customers through information provision. The competitive equilibrium features information dispersion and partial disclosure. Although conflicted fees lead to distorted information, they are irrelevant for customers' welfare: banning conflicted fees improves only the information quality, not customers' welfare. Instead, financial literacy education for the least informed customers can improve all customers' welfare because of a spillover effect. Furthermore, customers who trade through advisers realize lower average returns, which rationalizes empirical findings.
Does Borrowing from Banks Cost More than Borrowing from the Market?
Published: 10/30/2019 | DOI: 10.1111/jofi.12849
MICHAEL SCHWERT
This paper investigates the pricing of bank loans relative to capital market debt. The analysis uses a novel sample of loans matched with bond spreads from the same firm on the same date. After accounting for seniority, lenders earn a large premium relative to the bond‐implied credit spread. In a sample of secured term loans to noninvestment‐grade firms, the average premium is 140 to 170 bps or about half of the all‐in‐drawn spread. This is the first direct evidence of firms' willingness to pay for bank credit and raises questions about the nature of competition in the loan market.
