We explore the time variation of factor loadings and abnormal returns in the context of a four-factor model. Our methodology, based on an application of the Kalman filter and on endogenous uncertainty, overcomes several limitations of competing approaches used in the literature. Besides taking...

We model the financing, cash holdings, and hedging policies of a firm facing financing frictions and subject to permanent and transitory cash flow shocks. We show that permanent and transitory shocks generate distinct, sometimes opposite, effects on corporate policies and use the model to...

I develop a dynamic capital structure model to examine how the nature of risk affects firm's debt policy. In the model, firm's fundamental risk, captured by its cash flow process, consists of transitory and persistent parts with markedly different dynamics. The model explains the observed...

We consider a dynamic model of investment in which a firm can hold inventory to mitigate the price risk of an input commodity. Our model predicts that inventory allows to hedge against net worth risk by smoothing investment in capital, irrespective of the level of current net worth. Savings...

Using textual analysis of earnings conference calls, we quantify firms' supply chain risk and its sources. Our proxy for supply chain risk exhibits large cross-sectional and time-series variation that aligns with reasonable priors and is unprecedently high during the Covid-19 pandemic. In...

How do firms mitigate the impact of rising temperatures on employment? Using establishment-level data, we show that firms operating in multiple counties in the United States respond to heat shocks by reducing employment in the affected locations and increasing it in unaffected locations, whereas...

We model the interplay between cash and debt policies in the presence of financial constraints. While saving cash allows constrained firms to hedge against future cash flow shortfalls, reducing current debt – ‘saving borrowing capacity’ – is a more effective way of securing investment in...

We develop a dynamic model of investment, capital structure, leasing, and risk management based on firms' need to collateralize promises to pay with tangible assets. Both financing and risk management involve promises to pay subject to collateral constraints. Leasing is strongly collateralized...

We develop a dynamic model of investment, cash holdings, financing, and risk management policies in which firms face financing frictions and are subject to permanent and temporary cash flow shocks. In this model, target cash holdings depend on the long-term prospects of the firm, implying that...

This paper examines how the external information environment in which foreign subsidiaries operate affects the investment decisions of multinational corporations (MNCs). We hypothesize and find that the investment decisions of foreign subsidiaries in country-industries with more transparent...
