Although theologians and economists communicate their ideas to different professional audiences in different ways, we agree on many basic points. We agree, for instance, that all too often, a large gap appears between "what is" and "what should be." We agree, more specifically, that unregulated...

In cash-in-advance models, necessary and sufficient conditions for the existence of an equilibrium with zero nominal interest rates and Pareto optimal allocations place restrictions only on the very long-run, or asymptotic, behavior of the money supply. When these asymptotic conditions are...

In models with heterogeneous agents, issues of distribution and redistribution jump to the fore, raising the question: which policies--monetary or fiscal--work most effectively in transferring income from one group to another? To begin answering this question, this note works through a series of...

With an estimated New Keynesian model, this paper compares the "great recession" of 2007-09 to its two immediate predecessors in 1990-91 and 2001. The model attributes all three downturns to a similar mix of aggregate demand and supply disturbances. The most recent series of adverse shocks...

This paper constructs a two-country stochastic growth model in which neutral and investment-specific technology shocks are nonstationary but cointegrated across economies. It uses this model to interpret data showing that while real investment has grown faster than real consumption in the United...

This paper extends a New Keynesian model to include roles for currency and deposits as competing sources of liquidity services demanded by households. It shows that, both qualitatively and quantitatively, the Barnett critique applies: While a Divisia aggregate of monetary services tracks the...

In a New Keynesian model, technology and cost-push shocks compete as terms that stochastically shift the Phillips curve. A version of this model, estimated via maximum likelihood, points to the cost-push shock as far more important than the technology shock in explaining the behavior of output,...

A small, structural model of the monetary business cycle implies that real money balances enter into a correctly-specified, forward-looking IS curve if and only if they enter into a correctly-specified, forward-looking Phillips curve. The model also implies that empirical measures of real...

This paper extends a conventional cash-in-advance model to incorporate a real balance effect of the kind described by de Scitovszky, Haberler, Pigou, and Patinkin. When operative, this real balance effect eliminates the liquidity trap, allowing the central bank to control the price level even...

A two-sector real business cycle model, estimated with postwar U.S. data, identifies shocks to the levels and growth rates of total factor productivity in distinct consumption- and investment-goods-producing technologies. This model attributes most of the productivity slowdown of the 1970s to...
