An exogenous oil price shock raises inflation and contracts output, similar to a negative productivity shock. In the standard New Keynesian model, however, this does not generate any trade-off between inflation and output gap volatility: under a strict inflation-targeting policy, the output...

We assess the extent to which the period of great U.S. macroeconomic stability since the mid-1980s can be accounted for by changes in oil shocks and the oil share in GDP. To do this we estimate a DSGE model with an oil-producing sector before and after 1984 and perform counterfactual...

We study optimal monetary policy in an economy where firms’ debt overhangs lead to under-investment and under-production. The magnitude of this debt-induced distortion varies over the business cycle, rising significantly during recessions. When debt is contracted in nominal terms, this...

The present paper studies optimal monetary policy when the representative agent assumption is abandoned and financial wealth heterogeneity across households is introduced. Incomplete markets make households incapable of perfectly insuring against interest rate and inflation risk, creating a...

We study the macroeconomic implications of the debt overhang distortion. In our model, the distortion arises because investment is non-contractible—when a firm borrows funds, the debt contract cannot specify or depend on the firm’s future level of investment. After the debt contract is...

This paper assesses whether labor market frictions, in the form of searching and matching, can help explain movements in the labor wedge--the gap between the marginal rate of substitution (MRS) and the marginal productivity of labor in a perfectly competitive business cycle model. Results...
