Corporate agility – the ability to respond quickly and effectively to changing business conditions – is crucial for firms' success. While important, this concept is difficult to measure and use in quantitative research. By applying machine learning techniques, we develop reliable measures of agility and analyse how agile firms manage exposure to monetary policy uncertainty, a significant and frequently occurring form of threat. Agile firms' stocks are significantly less exposed to this uncertainty as they proactively apply risk management techniques to reduce their exposure. This has real consequences: agile firms' investments are less affected by monetary policy tightening episodes.

[We examine whether spin-offs or divestitures cause improvements in conglomerate investment efficiency. At issue are endogeneity of these restructuring decisions and correct measurement of investment efficiency. Endogeneity is a problem because the factors that induce firms to spin off or divest divisions may also improve investment efficiency; measurement error is a problem because efficiency measures employ Tobin's q as a noisy proxy for investment opportunities. We find important differences between firms that divest or spin off and a control sample. After accounting for these differences and for measurement error in q, we find no evidence of improvements in investment efficiency.]

Long CEO tenure can harm firm performance even after the CEO is replaced. We analyze this issue by conditioning post-turnover firm performance on the length of the preceding CEO’s tenure. Identification comes from instrumenting sudden CEO deaths as an exogenous shock to tenure length. We find that when a successor takes over after a long-tenured CEO, operating performance and stock returns are significantly lower, restructuring costs are higher, “big baths” are larger, and firm recovery is slower. Weaker corporate governance and a long-tenured CEO with lower skills amplify these post-turnover effects.

The paper analyzes the strategic waiting tendencies of IPO firms. Our game theoretic model shows why some high-quality firms may strategically delay their initial public offering until a favorable signal about the economic conditions is generated by other issuing firms. Survival analysis suggests that IPOs in the highest quality decile have significantly higher median waiting days (since the start of a rising IPO cycle) than the IPOs in the lowest decile. During the early stages of an expanding IPO cycle the average firm quality is lower than in its later stages. We find supporting evidence also from the IPOs of future S&P 500 firms.

Career concerns can limit a manager's willingness to take risks, which can lead to excessive policy conservatism. An increase in a CEO's ability and willingness to change jobs (CEO mobility) can diversify her human capital and reduce her conservatism. We derive several CEO mobility measures and relate them to a policy riskiness index that captures the overall risk embedded in a firm's corporate policies. We find a strong positive relation between CEO mobility and the riskiness of corporate policies. We also link external regulatory shocks that constrain labor mobility to significant drops in corporate risk-taking.

We examine whether spin-offs or divestitures cause improvements in conglomerate investment efficiency. At issue are endogeneity of these restructuring decisions and correct measurement of investment efficiency. Endogeneity is a problem because the factors that induce firms to spin off or divest divisions may also improve investment efficiency; measurement error is a problem because efficiency measures employ Tobin’s q as a noisy proxy for investment opportunities. We find important differences between firms that divest or spin off and a control sample. After accounting for these differences and for measurement error in q, we find no evidence of improvements in investment efficiency.

We examine the effect of policy uncertainty on firms' strategy of corporate social responsibility (CSR). During uncertain times, firms strategically increase their commitment to CSR causes. Policy uncertainty is positively associated with CSR performance regardless of the estimation method. CSR strategy can substitute for lobbying when firms attempt to manage policy uncertainty. Improved CSR performance can reduce firms' exposure to policy uncertainty which indicates that CSR commitment can deliver insurance-like benefits. The findings highlight the value of CSR commitments during uncertain times.

We analyze initial public offering (IPO) activity under political uncertainty surrounding gubernatorial elections in the United States. There are fewer IPOs originating from a state when it is scheduled to have an election. To establish identification, we develop a neighboring-states method that uses bordering states without elections as a control group. The dampening effect of elections on IPO activity is stronger for firms with more concentrated businesses in their home states, firms that are more dependent on government contracts (particularly state contracts), and harder-to-value firms. This dampening effect is related to lower IPO offer prices (hence, higher costs of capital) during election years.
