Working Papers

[4] Waiting or Acting: The Effects of Environmental Regulatory Uncertainty 


This paper explores how environmental regulatory uncertainty affects firms' environmental performance. It reveals that heightened uncertainty prompts firms to decrease pollutant emissions. Instead of adopting a "wait-and-see" approach, firms proactively engage in environmental innovation and adopt abatement technologies. Analysis indicates that institutional investors withdraw capital from polluting firms during periods of high environmental regulatory uncertainty. Causality is established using the Senate's pro-climate votes' standard deviation as an instrumental variable. The study also employs a difference-in-difference framework to analyze the Affordable Clean Energy (ACE) shock's impact. Overall, findings suggest a causal link between environmental regulatory uncertainty and firms' environmental efforts.

[5] Investment Function with Q in the Presence of Unobserved Shocks 

with Kyoo il Kim and Suyong Song

We study the classical relationship between a firm’s investment and Tobin’s q, for which unobserved persistent shocks such as productivity are other important factors of the firm’s investment decision. In our setting, besides the potential measurement problem of q, controlling for unobserved shocks becomes a new challenge. We develop an estimation method that addresses both econometric issues given timing and information set assumptions. Using 16,256 unique public firms in the U.S. from 1975 to 2021, we find that q remains a significant factor of investment even after controlling for the unobserved shocks.

[6] To Innovate or Not To Innovate When Times Are Bad 

with Petra Sinagl 

How are managerial incentives to innovate affected by financial crises? We study the role of managerial long-term compensation in inducing innovative output. We document that awarding managers with options during crises substantially increases their incentives to invest in risky projects and produce innovation. We find that an exogenous increase in CEO option pay awarded during times of high bank distress is associated with an increase in both the quantity and quality of innovation produced by the CEO's firm. In contrast, the same increase in option pay awarded during normal times does not have a significant effect on firm innovative output. We explain our results using Schumpeter's theory of creative destruction where managers exploit unique growth opportunities that arise during crises. Exogenous variation in option compensation is identified using pre-negotiated multi-year option plans.

[7] Disaster Risk, Politicians, Firms, and Capital Exuding: A New Role of Stock Market Participation 

with Art Durnev 

We propose a new function of stock market – to align voters’ preferences to politicians’ policies. We build a model with politicians’ ability to abate negative disaster shocks. Pro-business politicians are more likely to get re-elected when voters hold firm equity, and because of less severe disaster shocks, firms exude less capital and allocate investment more efficiently. We construct a novel stock market participation data for U.S. states using IRS statistics. We find that companies in states with higher stock market participation invest more efficiently and elect pro-business politicians. We use a novel neighboring states methodology and financial literacy instrument to eliminate endogeneity concerns.
