The standard model of signaling used in open economy macroeconomics concentrates on building a reputation when a policymaker's `type' is unknown. Observing tough policy leads market participants to raise the probability that a policymaker is tough, and therefore to expect tough policy in the...

Latin America began the twentieth century as a relatively poor region on the periphery of the world economy. One cause of a low level of income per person was capital scarcity. Long run growth via capital deepening requires either the mobilization of domestic capital through savings, or large...

We examine the cross-country dispersion in fiscal outcomes during 2007-2009. In principle, international differences in fiscal policy may be related to differences in optimal fiscal positions, funding constraints, political economy factors and fiscal control problems. We find that the decline in...

We use a simple model of a closed economy to study the recommendations of monetary policy-makers, attempting to respond optimally to an asset-price bubble whose stochastic properties they understand. We focus on the impact which the zero lower bound (ZLB) on nominal interest rates has on the...

We show that even when the exchange rate cannot be devalued, a small set of conventional fiscal instruments can robustly replicate the real allocations attained under a nominal exchange rate devaluation in a dynamic New Keynesian open economy environment. We perform the analysis under...

What fraction of the business cycle volatility of government purchases is accounted for as endogenous reactions to overall macroeconomic conditions? We answer this question in the framework of a neoclassical representative household model where the provision of a public consumption good is...

We argue that discretionary monetary policy exposes the economy to welfare-decreasing instability. It does so by creating the potential for private expectations about the response of monetary policy to exogenous shocks to be self-fulfilling. Among the many equilibria that are possible, some have...

While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...

In this paper, we measure the potential welfare gains from counter-cyclical policy in an economy with incomplete markets. In the course of conducting this measurement, we focus on two questions as central to the determination of those potential gains: (1) what is the likely effect of...

This paper explores the implications of economic and political inequality for the business cycle comovement of government purchases. We set up and compute a heterogeneous-agent neoclassical growth model, where households value government purchases which are financed by income taxes. A key...
