In this paper I first provide an overview of alternative approaches to money, contrasting the orthodox approach, in which money is neutral, at least in the long run; and the Marx-Veblen-Keynes approach, or the monetary theory of production. I then focus in more detail on two main categories: the...

Fiat money requires no backing to be accepted at a uniquely determined positive value. I show this using an equilibrium model with realistic frictions and rational households allowed to freely interact in a competitive environment. The model portrays a modern 'cashless' economy relying on...

We consider the desirability of modifying a standard Taylor rule for a central bank’s interest rate policy to incorporate either an adjustment for changes in interest rate spreads (as proposed by Taylor [2008] and McCulley and Toloui [2008]) or a response to variations in the aggregate volume...

We extend a standard New Keynesian model both to incorporate heterogeneity in spending opportunities along with two sources of (potentially time-varying) credit spreads and to allow a role for the central bank’s balance sheet in determining equilibrium. We use the model to investigate the...

This paper studies the welfare costs and the redistributive effects of inflation in the presence of idiosyncratic liquidity risk, in a micro-founded search-theoretical monetary model. We calibrate the model to match the empirical aggregate money demand and the distribution of money holdings...

This paper explores the influence of wage and price staggering on monetary persistence. We show that, for plausible parameter values, wage and price staggering are complementary in generating monetary persistence. We do so by proposing the new measure of "quantitative inertia," after discussing...

We present a model of central bank collateralized lending to study the optimal choice of the haircut policy. We show that a lending facility provides a bundle of two types of insurance: insurance against liquidity risk as well as insurance against downside risk of the collateral. Setting a...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

The paper extends the efficiency wages Phillips curve from a closed economy context to an open economy one with both commodity trade and capital mobility. Opening the trade account does not alter the slope of the Phillips curve, but it makes its position a function of the change of foreign and...
