I characterize cyclical fluctuations in the cross-sectional dispersion of firm-level productivity in the U.S. manufacturing sector. Using the estimated dispersion, or "risk," stochastic process as an input to a baseline DSGE financial accelerator model, I assess how well the model reproduces...

A large literature documents a heterogeneous asset price response to macroeconomic news announcements. In order to explain these differences, we define the intrinsic value of a macroeconomic announcement as its ability to nowcast GDP growth, inflation and the federal funds target rate. We then...

The paper is based on a talk given in April 2010. It traces the roots of the recent financial crisis from development of the limited liability corporation, to separation of ownership from control, tax incentives for debt financing, investment bankers moving to the corporate form, government...

By April 2013, the FCC's recent bill-shock agreement with cellular carriers requires consumers be notified when exceeding usage allowances. Will the agreement help or hurt consumers? To answer this question, we estimate a model of consumer plan choice, usage, and learning using a panel of...

Consumption is partly a social activity, yet most studies of consumer behavior treat households in isolation. We investigate familial relationships in consumption patterns using a sample of parents and their children from the Panel Study of Income Dynamics. We find a positive and statistically...

We investigate the impact of debt on a panel of U.S. manufacturing firms' capital investment behavior as the underlying firm-specific and macroeconomic uncertainty changes. Our estimates show that the influence of leverage on capital investment may be stimulating or mitigating depending on the...

This paper investigates the link between the optimal level of nonfinancial 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...

We investigate the relationship between a firm's measures of corporate governance, macroeconomic uncertainty and changes in leverage. Recent research highlights the role of governance in financing decisions. Previous research also indicates that macroeconomic uncertainty affects a firm’s...

This paper examines the role of interest rate policy in a small open economy subject to terms of trade shocks and time-varying currency risk responding to domestic exchange rate volatility. The private sector makes optimal decisions in an intertemporal non-linear setting with...

This paper presents a model in which "instrument uncertainty"-that is, an uncertain mapping from monetary policy to macroeconomic outcomes-may mitigate the inflationary bias problem that arises when efficient monetary policy rules are time- inconsistent. If the relation between monetary policy...
