Optimal monetary policy with distinct core and headline inflation rates
In a stylized DSGE model with an energy sector, the optimal policy response to an adverse energy supply shock implies a rise in core inflation, a larger rise in headline inflation, and a decline in wage inflation. The optimal policy is well-approximated by policies that stabilize the output gap, but also by a wide array of "dual mandate" policies that are not overly aggressive in stabilizing core inflation. Finally, policies that react to a forecast of headline inflation following a temporary energy shock imply markedly different effects than policies that react to a forecast of core, with ...

The Effects of Foreign Shocks when Interest Rates are at Zero
In a two-country DSGE model, the effects of foreign demand shocks on the home country are greatly amplified if the home economy is constrained by the zero lower bound on policy interest rates. This result applies even to countries that are relatively closed to trade such as the United States. Departing from many of the existing closed-economy models, the duration of the liquidity trap is determined endogenously. Adverse foreign shocks can extend the duration of the trap, implying more contractionary effects for the home country. The home economy is more vulnerable to adverse foreign shocks if ...

Optimal monetary policy with staggered wage and price contracts
We formulate an optimizing-agent model in which both labor and product markets exhibit monopolistic competition and staggered nominal contracts. The unconditional expectation of average household utility can be expressed in terms of the unconditional variances of the output gap, price inflation, and wage inflation. Monetary policy cannot replicate the Pareto-optimal equilibrium that would occur under completely flexible wages and prices; that is, the model exhibits a tradeoff between stabilizing the output gap, price inflation, and wage inflation. The Pareto optimum is attainable only if ...

Imperfect credibility and inflation persistence
In this paper, we formulate a dynamic general equilibrium model with staggered nominal contracts, in which households and firms use optimal filtering to disentangle persistent and transitory shifts in the monetary policy rule. The calibrated model accounts quite well for the dynamics of output and inflation during the Volcker disinflation, and implies a sacrifice ratio very close to the estimated value. Our approach indicates that inflation persistence and substantial costs of disinflation can be generated in an optimizing-agent framework, without relaxing the assumption of rational ...

Fiscal consolidation in a currency union: spending cuts vs. tax hikes
This paper uses a two country DSGE model to examine the effects of tax-based versus expenditure-based fiscal consolidation in a currency union. We find three key results. First, given limited scope for monetary accommodation, tax-based consolidation tends to have smaller adverse effects on output than expenditure-based consolidation in the near-term, though is more costly in the longer-run. Second, a large expenditure-based consolidation may be counterproductive in the near-term if the zero lower bound is binding, reflecting that output losses rise at the margin. Third, a "mixed strategy" ...

Is there a fiscal free lunch in a liquidity trap?
This paper uses a DSGE model to examine the effects of an expansion in government spending in a liquidity trap. If the liquidity trap is very prolonged, the spending multiplier can be much larger than in normal circumstances, and the budgetary costs minimal. But given this "fiscal free lunch," it is unclear why policymakers would want to limit the size of fiscal expansion. Our paper addresses this question in a model environment in which the duration of the liquidity trap is determined endogenously, and depends on the size of the fiscal stimulus. We show that even if the multiplier is high ...

Oil shocks and external adjustment
This paper investigates how oil price shocks affect the trade balance and terms of trade in a two country DSGE model. We show that the response of the external sector depends critically on the structure of financial market risk-sharing. Under incomplete markets, higher oil prices reduce the relative wealth of an oil-importing country, and induce its nonoil terms of trade to deteriorate, and its nonoil trade balance to improve. The magnitude of the nonoil terms of trade response hinges on structural parameters that affect the divergence in wealth effects across oil importers and exporters, ...

Money-Financed Fiscal Programs : A Cautionary Tale
A number of prominent economists and policymakers have argued that money-?nanced ?scal programs (helicopter drops) could be e?cacious in boosting output and in?ation in economies facing persistent economic weakness, very low in?ation, and signi?cant ?scal strains. We employ a fairly conventional macroeconomic model to explore the possible e?ects of such policies. While we do ?nd that money-?nanced ?scal programs, if communicated successfully and seen as credible by the public, could provide signi?cant stimulus, we underscore the risks that would be associated with such a program. These risks ...
