This paper investigates the link between the optimal level of non-financial firms' leverage and macroeconomic uncertainty. We develop a structural model of a firm's value maximization problem that predicts that as macroeconomic uncertainty increases the firm will decrease its optimal level of...

This paper investigates the link between the optimal level of non-financial firms? liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms alter their liquidity ratio in response to changes in either macroeconomic or...

This paper investigates the link between the optimal level of non- financial firms’ liquid assets and uncertainty. We develop a partial equilibrium model of precautionary demand for liquid assets showing that firms change their liquidity ratio in response to changes in either macroeconomic or...

We derive robust predictions on the effects of uncertainty on short run investment dynamics in a broad class of models with (partial) irreversibility. When their environment becomes more uncertain firms become more cautious and less responsive to demand shocks. This result contrasts with the...

Recent empirical studies suggest that the negative effects of uncertainty shocks are stronger in recessions than during booms. In this study, I provide a theoretical mechanism that can explain this empirical observation. I start from the argument that the effect of uncertainty on investment...

Uncertainty appears to have both a short-run and a long-run component, which we measure using firm and macro implied volatility data from equity options of 30 days to 5 years duration. We ask what may be driving uncertainty over these different time horizons, finding that policy uncertainty,...

We propose uncertainty shocks as a new shock that drives business cycles. First, we demonstrate that microeconomic uncertainty is robustly countercyclical, rising sharply during recessions, particularly during the Great Recession of 2007-2009. Second, we quantify the impact of timevarying...

This study tests for the presence of real options effects induced by uncertainty and (partial) irreversibility on fixed capital investment using Italian company data. Our approach recognizes that firm-level investment spending may, itself, be aggregated over multiple investment decisions in...
