The Modigliani-Miller theorem is fundamental to the theory of corporate finance. One of the theorem's immediate implications is that there is no reason for the monetary authority to respond to asset prices. This article posits a world in which the Modigliani-Miller theorem does not hold. The...

An analysis of the quantitative effects of agency costs in a real business cycle model, showing that these costs can explain why output growth displays positive autocorrelation at short horizons.

It is well known that sunspot equilibria may arise under an interest-rate operating procedure in which the central bank varies the nominal rate with movements in future inflation (a forward-looking Taylor rule). This paper demonstrates that these sunspot equilibria may be learnable in the sense...

There is growing evidence that the empirical Phillips curve within the US has changed significantly since the early 1980’s. In particular, inflation persistence has declined sharply. The paper demonstrates that this decline is consistent with a standard Dynamic New Keynesian (DNK) model in...

Should monetary policy respond to asset prices? This paper analyzes a general equilibrium model with imperfect capital markets and rigid nominal wages. Within the context of this model, there is a natural role for the benevolent central bank to dampen the real effects of asset price movements.

This paper extends the implicit contracts framework to allow for on-the-job search. It is shown that involuntary unemployment can arise in such a framework without placing any a priori restrictions on either wages or severance payments. The model also implies that firms will practice a two-tier...

This paper integrates money into a real model of agency costs. Money is introduced by imposing a cash-in-advance constraint on a subset of transactions. The underlying real model is a standard real-business-cycle model modified to include endogenous agency costs. The paper’s chief contribution...

An argument that variations of extant general-equilibrium monetary models can generate real-time economic forecasts comparable in accuracy to those contained in the Federal Reserve Board's "Greenbook" briefing documents.

The authors analyze the restrictions necessary to ensure that the interest-rate policy rule used by the central bank does not introduce real indeterminacy into the economy. They conduct this analysis in a flexible price economy and a sticky price model that satisfies the natural rate hypothesis....
