Knowledge that Transforms

Using 31 years of data (1990–2020) on U.S. Treasury dealer positions, we find that Treasury issuance is the main driver of dealers’ weekly inventory changes. Such inventory fluctuations are only partially offset in adjacent weeks and not significantly hedged with futures. Dealers are compensated for inventory risk by means of subsequent price appreciation of their holdings. Amid increased balance sheet costs attributable to post-crisis regulatory changes, dealers significantly reduce their position taking and layoff inventory faster. Moreover, the increased participation of non-dealers (investment funds) in the primary market contributes to diminishing compensation for inventory risk taken on at auctions.

In the U.S., student debt is currently the second largest component of consumer debt. Households are required to repay these loans early in their lifecycle, when marginal utility is particularly high. We study alternative contracts that offer partial or full payment deferral until later in life. We calibrate an economy with the current contracts, and then solve for counterfactual equilibria. The alternative contracts yield large welfare gains, which are robust to assumptions about the behavior of the lenders and borrower preferences. The gains are similar to those that could come from the debt relief program currently being considered in the U.S., but without its adverse fiscal implications.

We study aggregate lapsation risk in the life insurance sector. We construct two lapsation risk factors that explain a large fraction of the common variation in lapse rates of the 30 largest life insurance companies. The first is a cyclical factor that is positively correlated with credit spreads and unemployment, while the second factor is a trend factor that correlates with the level of interest rates. Using a novel policy-level database from a large life insurer, we examine the heterogeneity in risk factor exposures based on policy and policyholder characteristics. Young policyholders with higher health risk in low-income areas are more likely to lapse their policies during economic downturns. We explore the implications for hedging and valuation of life insurance contracts . Ignoring aggregate lapsation risk results in mispricing of life insurance policies. The calibrated model points to overpricing on average. In the cross-section, young, low-income, and high-health risk households face higher effective mark-ups than the old, high-income, and healthy.

This paper studies the causal effects of personal investment taxes on stock returns and the financial decisions of companies. I exploit a change in legislation in 2013 which allowed stocks listed on the Alternative Investment Market, a sub-market of the London Stock Exchange, to be held in capital gains and dividend tax-exempt investment accounts for the first time. Using a difference-in-differences approach, I find that excess stock returns decreased by their pre-legislation change effective tax rate, and that firms adjusted their capital structure and increased their spending on dividends, capital, and labour, in-line with the “traditional view” of corporate investment.

Recent theories and narratives highlight the potential role of associative recall in driving overreaction in expectations and market behavior. Based on a simple model, we test this idea through a series of experiments in which news are communicated with memorable contexts. Because the experimental participants predominantly remember those past news that get cued by new information, their beliefs about fundamentals strongly overreact. In a betting market experiment, associative recall translates into overreaction in market prices, which makes realized prices too extreme. Our results highlight the importance of associative memory for beliefs and financial decisions.

This paper develops two new methods to infer a mutual fund's proxy advisors from SEC filings. It then applies these methods to characterize features of the proxy advice industry from 2007 to 2021: (i) As of 2021, ISS and Glass Lewis collectively control approximately 90 percent of the market. During this period, the market share of ISS remains stable, while that of Glass Lewis has increased. (ii) When a proxy advisor issues a recommendation opposing management, its customers are approximately 20 percentage points more likely to also oppose management compared to other investors. (iii) Funds that subscribe to both proxy advisors tend to vote more similarly to the recommendations of the advisor whose voting platform they use. (iv) Proxy advisors often change their advisory stance when investors disagree with their previous advice. I offer suggestive evidence that this adaptation reflects both learning from informed investors and a desire by proxy advisors to align with the preferences of their customers.

To prevent issuers from inflating their share prices, SEC Rule 10b-18 sets price ceilings on share repurchases through open markets. We find that market-structure reforms in the 1990s and 2000s dramatically increased share repurchases because they relaxed constraints on issuers competing with other buyers under price ceilings. The Tick Size Pilot Program, a controlled experiment that partially reversed previous reforms, significantly reduced share repurchases. We estimate that price ceilings and reduced market-structure frictions explain 18% of the secular increase in share repurchases. Meanwhile, these two frictions still exist, which explains why share repurchases have not crowded out dividends entirely.

This paper studies the heterogeneous effects of subjective macroeconomic expectations on the cross-section of equity returns. We argue that an upward revision in expectations of macroeconomic productivity might be accompanied by an excessive increase in investment and external financing, inflated current equity prices, and thus lowered subsequent returns, particularly for financially constrained firms. Thus, following upward revisions in expectations of macroeconomic productivity, subsequent returns are relatively low for small firms, value firms, low-investment firms, risky firms, unprofitable firms, low-quality firms, and financially distressed firms—all of which are more financially constrained. In sharp contrast, following downward revisions in expectations of macroeconomic productivity, these categories of firms earn relatively high subsequent returns. We find that revisions in subjective macroeconomic expectations induce strong predictable time variation in a large set of anomalies. In particular, favorable revisions in expectations of macroeconomic productivity predict significantly stronger profitability, quality, distress, and low-risk anomalies but weaker value, investment, and size anomalies.

Economic theory suggests that production complementarity is an important driver of sectoral co-movements and business cycle fluctuations. We operationalize this concept using a measure of production complementarity proximity (COMPL) between any two companies. We show firms from different industries but are closely aligned in COMPL exhibit strong co-movement in their operating, investing, and financing activities, as well as quarterly earnings revisions and monthly returns. We further document a lead-lag effect in their returns, such that a long-short strategy based on recent COMPL peer returns yields a monthly 6-factor alpha of 122 basis points. This inter-industry momentum spillover effect is not explained by other network-based mechanisms, such as shared analyst coverage. We conclude information transmission takes place along complementarity networks, but stock prices do not update instantaneously.

We study whether state-level mandatory business closures implemented in response to the outbreak of the Covid-19 causally affect economic and health outcomes. Using plausibly exogenous variations in exposure to these restrictions, we find that they impose substantial losses to firms and workers, the former bearing approximately two thirds of the cost, consistent with firms partially insuring their workers. We show that mandatory business closures have a significant negative causal effect on mortality rates, particularly in areas featuring contact-intensive occupations. We discuss the assumptions under which the health benefits of business closures exceed their associated economic costs.
