Knowledge that Transforms

Elementary portfolio theory implies that environmentalists optimally hold more shares of polluting firms than non-environmentalists, and that polluting firms attract more investment capital than otherwise identical non-polluting firms through a hedging channel. Pigouvian taxation can reverse the aggregate investment results, but environmentalists still overweight polluters. We introduce countervailing motives for environmentalists to underweight polluters, comparing the implications when environmentalists coordinate to internalize pollution, or have nonpecuniary disutility from holding polluter stock. With nonpecuniary disutility, introducing a green derivative may dramatically alter who invests most in polluters, but has no impact on aggregate pollution.

This article shows how sustainable investing—through the joint practice of exclusionary screening and environmental, social, and governance (ESG) integration—affects asset returns. I develop an asset pricing model with partial segmentation and heterogeneous preferences. I characterize two exclusion premia generalizing Merton’s (1987) premium on neglected stocks and a taste premium that clarifies the relationship between ESG and financial performance. Focusing on US stocks, I estimate the model by applying it to sin stocks as excluded assets and using the holdings of green funds to proxy for environmental integration. The average annual exclusion effect is 2.79% for the period 1999–2019. Although the annual taste effect ranges from –1.12% to + 0.14% across industries for 2007–19, the taste effect spread between the top and bottom terciles of companies within each industry can exceed 2% per year. Finally, I estimate and explain the dynamics of these premia.

We quantify the importance to mutual fund flows of affiliation between funds and their distributors. Bank failures create exogenous variation in retail customers’ exposure to bank-affiliated mutual funds. When a bank fails, its customers are moved to other banks that distribute their own affiliated mutual funds. Following such exogeneous bank shifts, customers sell their fund holdings and replace them with funds affiliated with their new banks. Customers react sequentially over time. After 4 years, a third of customers’ investments have been reallocated. In spite of large reallocations, investors do not end up with better-performing fund portfolios.

I show that increased turnover accompanies changes in stocks’ risk exposures. A one standard deviation decrease in a stock’s market beta increases turnover as much as 25%. The sensitivity of turnover to beta changes has grown over time. Market beta changes explain as much as 5% of the monthly cross-sectional variation in turnover. VAR decompositions of returns show turnover is more strongly associated with discount rate news than cash flow news. This mechanism provides a new channel for turnover combined with realized returns to predict long horizon returns and cash flow changes. Further, this mechanism can amplify many prior explored motives for trade.

Active mutual funds supply liquidity when demanding it becomes uneconomical. They tilt toward cheaper buy trades after inflows deplete their trading ideas, when trading ideas in general run low, and when they have more stocks to supply liquidity to, and their cheaper trades perform worse. Their largest trades are more likely to supply liquidity, explaining why they were not broken up. Funds perform better when they pay more for their buys and perform worse when they pay more for their sells, consistent with the implied value of the trades and the correlation between what a fund trades and what it holds.

We study local loan conditions when banks close branches. In places where branch closures do not take place, firms that purposely switch banks receive a sixty-three basis points (bps) discount. However, after the closure of nearby branches of their credit-granting banks, firms that locally and hurriedly transfer to other banks receive no such discount. Yet, the loan default rate for the latter (more expensive) transfer loans is on average a full percentage point lower than that for the former (cheaper) switching loans. This suggests that transfer firms are of “better” quality than switching firms. In sum, even if local markets remain competitive, when banks close branches, firms lose.

This paper investigates the effect of access to finance on job growth in over 780,000 firms across twenty-two developing countries. Using the introduction of credit bureaus as an exogenous shock to the supply of credit, the paper finds that increased access to finance results in higher employment growth, especially among micro, small, and medium enterprises. The results are robust to using firm-fixed effects, industry measures of external finance dependence, and propensity score matching. Our findings have implications for policy interventions targeted to produce job growth.

We test whether high-frequency net-debt issuers (HFIs)—public industrial companies with relatively low issuance costs and high debt-financing benefits—manage leverage toward long-run targets. Our answer is they do not: (1) the leverage–profitability correlation is negative even in quarters with leverage rebalancing; (2) the speed-of-adjustment to target leverage deviations is no higher for HFIs than for low-frequency net-debt issuers; and (3) under-leveraged HFIs do not speed up rebalancing activity in significant investment periods. Thus, even in the subset of firms most likely to follow dynamic trade-off theory, the theory does not appear to hold.

We introduce an arbitrage-free term structure model of nominal and real yields that accounts for liquidity risk in Treasury inflation-protected securities (TIPS). The novel feature of our model is to identify liquidity risk from individual TIPS prices by accounting for the tendency that TIPS, like most fixed-income securities, go into buy-and-hold investors’ portfolios as time passes. We find a sizable and countercyclical TIPS liquidity premium, which helps our model to match TIPS prices. Accounting for liquidity risk also improves the model’s ability to forecast inflation and match surveys of inflation expectations.

This article studies how early-stage entrepreneurs respond to negative feedback about the quality of their ventures. We use data from new venture competitions, some of which privately inform founders of their relative rank. The empirical strategy compares lower and higher ranked losers across competitions in which they did and did not observe their standing. Receiving negative feedback increases average venture abandonment by 13%. Differences in responsiveness—for example, in venture risk, venture maturity, and signal precision—are consistent with particular theories about entrepreneurship, including the importance of experimentation.
