    Title: "The consequences to directors of deploying poison pills" with Jon Karpoff and Michael Wittry


    Abstract: We examine the labor market consequences for directors who adopt poison pills. Directors who become associated with pill adoption experience significant decreases in vote margins and increases in termination rates across all their directorships. They also experience a decrease in the likelihood of new board appointments. Firms have positive abnormal stock price reactions when pill-associated directors die or depart their boards, compared to zero abnormal returns for other directors. Further tests indicate that these adverse consequences accrue primarily to directors involved in the adoption of pills at seasoned firms and not at young firms. We conclude that directors who become associated with poison pill adoption suffer a decrease in the value of their services, and that the director labor market thus plays an important role in firms’ governance.

    Title: Sustainable Investing in Equilibrium

    Abstract: We present a model of investing based on environmental, social, and governance (ESG) criteria. In equilibrium, green assets have negative alphas, whereas brown assets have positive alphas. The ESG investment industry is at its largest, and the alphas of ESG-motivated investors are at their lowest, when there is large dispersion in investors' ESG preferences. When this dispersion shrinks, so does the ESG industry, even if all investors' ESG preferences are strong. Greener assets are more exposed to an ESG risk factor, which captures shifts in customers' tastes for green products or investors' tastes for green holdings. Under plausible conditions, the latter tastes produce positive social impact.

    Title: Delegated Investment Decisions and Rankings

    Abstract: Two aspects of social context are central to the finance industry. First, financial professionals usually make investment decisions on behalf of third parties. Second, social competition, in the form of performance rankings, is pervasive. Therefore, we investigate professionals' risk-taking behaviour under social competition when investing for others. We run online and lab-in-the-field experiments with 965 financial professionals and show that professionals increase their risk taking for others when they lag behind. Additional survey evidence from 1,349 respondents reveals that professionals' preferences for high rankings are significantly stronger than those of the general population.

    Title: Perceived Precautionary Savings Motives: Evidence from FinTech

    Abstract: We study the consumption response to the provision of credit lines to individuals that previously did not have access to credit combined with the possibility to elicit directly a large set of preferences, beliefs,  and motives. As expected, users react to the availability of credit by increasing their spending permanently and reallocating consumption from non-discretionary to discretionary goods and services. Surprisingly,  though, liquid users react more than others and this pattern is a robust feature of the data. Moreover, liquid users lower their savings rate, but do not tap into negative deposits. The credit line seems to act as a  form of insurance against future negative shocks and its mere presence makes users spend their existing liquidity without accumulating any debt. By eliciting preferences, beliefs, and motives directly, we show these results are not fully consistent with models of financial constraints, buffer stock models with and without durables, present-bias preferences, uncertainty about future income, bequest motives, or the canonical life-cycle permanent income model. We label this channel the perceived precautionary savings channel, because liquid households behave as if they faced strong precautionary savings motives even though no observables suggest they should based on standard theoretical models.

    Title: Opening up the Black Box: the Impact of Technological Transparency on Self-Protection

    Abstract: This article discusses the behavioral and welfare implications of uncovering the mechanism of self-protection technologies. Based on a new interpretation of self-protection, we introduce the concept of technological transparency -- the extent to which the mechanism of the technology is understood. We analyze the consequence of improved technological transparency according to whether the improvement stems from uncovering exogenous or endogenous risk determinants. We show that technological transparency improves welfare through enabling more efficient prevention, but this welfare improvement may be undermined or even reversed if information is incompletely disclosed or if the risk can be insured through private insurance markets. We also show that technological transparency affects behavior through an ex ante information channel and an ex post regret channel. Our findings have implications on the cost-benefit analysis of scientific research conducted to identify hidden risk determinants. They also inform the design of personalized preventive healthcare, as well as information campaigns to promote public safety.

    Title: Leverage

    Abstract: Differential variation in households’ risk preferences over the business cycle affects the demand and supply of debt securities, which, in turn, affect intermediaries’ balance sheets. As in the data, our frictionless model predicts that intermediaries’ debt declines in contractions when their financial risk increases and asset prices drop, thus mimicking active deleveraging. As intermediaries’ leverage proxies for aggregate risk aversion, it predicts asset returns. Our model is consistent with poorer households borrowing more and with levered households deleveraging in crisis and "fire selling" their risky securities. Yet, as empirically observed, their debt-to-wealth ratios increase as higher discount rates make their wealth decline faster.
