This paper argues that limited asset market participation is crucial in explaining U.S. macroeconomic performance and monetary policy before the 1980s, and their changes thereafter. We develop an otherwise standard sticky-price dynamic stochastic general equilibrium model, which implies that at...

When enough agents do not participate in asset markets, the slope of the aggregate demand curve is reversed. Monetary policy should be passive, to ensure equilibrium determinacy and to minimize variations in output and inflation. This paper presents evidence that asset markets participation in...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. When government spending provides direct utility to the household, its optimal level is at most 0.5-1 percent of GDP for recessions of -4 percent; the numbers are...

In an economy with financial imperfections, Ricardian equivalence holds when prices are flexible and the steady-state distribution of consumption is uniform, or labor is inelastic. With different steady-state consumption levels, Ricardian equivalence fails, but tax cuts, somewhat paradoxically,...

The effects of public debt and redistribution are intimately related. We illustrate this in a model with heterogenous agents and imperfect credit markets. Our setup di¤ers from the classic Savers-Spenders model of ?scal policy in that all agents engage in intertemporal optimization, but a...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. We illustrate this point in the context of a standard New Keynesian model. In that model, when government spending provides direct utility to the household, its...

We study the effects of electoral institutions on the size and composition of public expenditure in OECD and Latin American countries. We present a model emphasizing the distinction between purchases of goods and services, which are easier to target geographically, and transfers, which are...
