Uncertainty, Financial Frictions, and Investment Dynamics
Micro- and macro-level evidence indicates that fluctuations in idiosyncratic uncertainty have a large effect on investment; the impact of uncertainty on investment occurs primarily through changes in credit spreads; and innovations in credit spreads have a strong effect on investment, irrespective of the level of uncertainty. These findings raise a question regarding the economic significance of the traditional "wait-and-see" effect of uncertainty shocks and point to financial distortions as the main mechanism through which fluctuations in uncertainty affect macroeconomic outcomes. The ...

Aggregate Implications of Deviations from Modigliani-Miller: A Sufficient Statistics Approach
A few sufficient statistics can identify the aggregate effects of distortions to firm investment in a class of general equilibrium models that can accommodate rich general equilibrium effects including endogenous firm entry. This result does not depend on the microfoundation of the distortion; one can generate inferences about aggregate effects that apply for multiple microfoundations or in cases where a fully specified model is difficult to solve. To demonstrate the relevance of themethodology, we use it to quantify the aggregate consequences of costly external equity financing and a ...

Inflation dynamics during the financial crisis
Firms with limited internal liquidity significantly increased prices in 2008, while their liquidity unconstrained counterparts slashed prices. Differences in the firms' price-setting behavior were concentrated in sectors likely characterized by customer markets. The authors develop a model in which firms face financial frictions while setting prices in a customer-markets setting. Financial distortions create an incentive for firms to raise prices in response to adverse demand or financial shocks. These results reflect the firms' reaction to preserve internal liquidity and avoid accessing ...
