This paper presents a model in which some goods trade in "customer markets." In these markets, advertising plays a critical role in facilitating long-lived relationships. We estimate both policy and non-policy parameters of the model (which includes New-Keynesian frictions) on U.S. data,...

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...

This paper develops an affine model of the term structure of interest rates in which bond yields are driven by observable and unobservable macroeconomic factors. It imposes restrictions to identify the effects of monetary policy and other structural disturbances on output, inflation, and...

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...

Over the last twenty-five years, a set of influential studies has placed interest rates at the heart of analyses that interpret and evaluate monetary policies. In light of this work, the Federal Reserve’s recent policy of "quantitative easing," with its goal of affecting the supply of liquid...

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...

In the United States, eradication of persistent federal deficits has won broad bipartisan support. At the same time, political pressures have mounted to strengthen the Federal Reserve's explicit concern with price stability. Proposals under consideration would require a much narrower focus on...

We revisit Obstfeld and Rogoff's (1995) results on exchange rate dynamics in a two-country, monetary model with incomplete asset markets, stationary net foreign assets, and endogenous nominal interest rate setting a la Taylor (1993). Under flexible prices, the nominal exchange rate exhibits a...

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...
