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...

Openness per se requires optimal monetary policy to deviate from the canonical closed-economy principle of domestic price stability, even if domestic prices are the only ones to be sticky. I review this argument using a simple partial equilibrium analysis in an economy that trades in final...

We study the gains from increased wage flexibility and their dependence on exchange rate policy, using a small open economy model with staggered price and wage setting. Two results stand out: (i) the impact of wage adjustments on employment is smaller the more the central bank seeks to stabilize...

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,...

Does it matter, for the size of the government spending multiplier, which category of agents bears the brunt of the necessary adjustment in taxes? In an economy with heterogeneous agents and imperfect financial markets, the answer depends on whether or not New Keynesian features, such are price...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a tractable canonical system in domestic inflation and the output gap. We employ this framework to analyse the macroeconomic implications of three alternative monetary...

There has been a lot of interest recently in developing small-scale rule-based empirical macro models for the analysis of monetary policy. These models, based on the conventional view that inflation stabilization should be a concern of monetary policy only, have typically neglected the role of...

We document that an increase in government purchases generates a rise in consumption, the real and the product wage, and a fall in the markup. This evidence is robust across alternative empirical methodologies used to identify innovations in government spending (structural VAR vs. narrative...

Econometric evidence suggests that, in response to monetary policy shocks, durable and non-durable spending comove positively, and durable spending exhibits a much larger sensitivity to the policy shocks. A standard two-sector New Keynesian model with free borrowing persistently exhibits a...

We analyze optimal monetary policy in a small open economy characterized by home bias in consumption. Peculiar to our framework is the application of a Ramsey-type analysis to a model of the recent open economy New Keynesian literature. We show that home bias in consumption is a sufficient...
