We use variation in state corporate income tax rates to re-examine the relation between taxes and corporate leverage. Contrary to prior research, we find that corporate leverage rises after tax cuts for small private firms. An estimated dynamic equilibrium model shows that tax cuts make capital...

We create a firm-level ChatGPT investment score, based on conference calls, that measures managers' anticipated changes in capital expenditures. We validate the score with interpretable textual content and its strong correlation with CFO survey responses. The investment score predicts future...

We compare the investment of standalone firms across regions after a positive shock to the investment opportunities generated by a large-scale highway development project. We show that the standalones' investment sensitivity is lower in regions with a higher density of business groups in the...

Textbook theory assumes that firm managers maximize the net present value of future cash flows. But when you ask them, real-world firm managers consistently say that they are maximizing something else entirely: earnings per share (EPS). Perhaps this is a mistake. No matter. We take firm managers...

We review the literature on financial intermediation in the process by which new medical therapeutics are financed, developed, and delivered. We discuss the contributing factors that lead to a key finding in the literature--underinvestment in biomedical R&D--and focus on the role that banks and...

We study the effects of monetary-policy-induced changes in Tobin's q on corporate investment and capital structure. We develop a theory of the mechanism, provide empirical evidence, evaluate the ability of the quantitative theory to match the evidence, and quantify the relevance for monetary...

Using firm-level administrative tax data on the 43% of business liabilities in the United States tied to privately held firms, we document dramatic reductions in leverage since the Great Recession. Leverage for the average private firm fell fifteen percent between 2004 and 2018. In contrast,...

Public attention to a firm may provide valuable monitoring, but it may also have a dark side by constraining management's decisions and distracting it. We use inclusion in the S&P 500 index as a positive shock to public attention. Media coverage, Google searches, SEC downloads, SEC comment...

We analyze the financial performance of a hypothetical portfolio of 120 mRNA vaccine candidates in the preclinical stage targeting 11 emerging infectious diseases. We calibrate the simulation parameters with input from domain experts in mRNA technology and an extensive literature review. We find...
