We estimate the effects of fiscal policy on the labor market in US data. An increase in government spending of 1 percent of GDP generates output and unemployment multipliers respectively of about 1.2 per cent (at one year) and 0.6 percentage points (at the peak). Each percentage point increase...

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 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...

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,...

We study the design of monetary policy in an estimated model with sticky prices, search and matching frictions, and staggered nominal wage bargaining. We find that the estimated natural rate of unemployment is consistent with the NBER description of the U.S. business cycle, and that the...

We use an estimated monetary business cycle model with search and matching frictions in the labor market and nominal price and wage rigidities to study four countries (the U.S., the U.K., Sweden, and Germany) during the financial crisis and the Great Recession. We estimate the model over the...

We use a standard quantitative business cycle model with nominal price and wage rigidities to estimate two measures of economic inefficiency in recent U.S. data: the output gap---the gap between the actual and efficient levels of output---and the labor wedge---the wedge between households'...

Empirical evidence suggests that severe economic downturns, characterized by deleverage, are preceded by phenomena of debt overhang. Hence large recessions may not result from large shocks, but, rather, from typical shocks interacting with the state of the economy. We study a stochastic economy...

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...
