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" ...

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, ...

The Macroeconomic Risks of Undesirably Low Inflation
This paper investigates the macroeconomic risks associated with undesirably low inflation using a medium-sized New Keynesian model. We consider different causes of persistently low inflation, including a downward shift in long-run inflation expectations, a fall in nominal wage growth, and a favorable supply-side shock. We show that the macroeconomic effects of persistently low inflation depend crucially on its underlying cause, as well as on the extent to which monetary policy is constrained by the zero lower bound. Finally, we discuss policy options to mitigate these effects.

Trade adjustment and the composition of trade
A striking feature of U.S. trade is that both imports and exports are heavily concentrated in capital goods and consumer durables. However, most open economy general equilibrium models ignore the marked divergence between the composition of trade flows and the sectoral composition of U.S. expenditure, and simply posit import and exports as depending on an aggregate measure of real activity (such as domestic absorption). In this paper, we use a SDGE model (SIGMA) to show that taking account of the expenditure composition of U.S. trade in an empirically-realistic way yields implications for the ...

The transmission of domestic shocks in the open economy
This paper uses an open economy DSGE model to explore how trade openness affects the transmission of domestic shocks. For some calibrations, closed and open economies appear dramatically different, reminiscent of the implications of Mundell-Fleming style models. However, we argue such stark differences hinge on calibrations that impose an implausibly high trade price elasticity and Frisch elasticity of labor supply. Overall, our results suggest that the main effects of openness are on the composition of expenditure, and on the wedge between consumer and domestic prices, rather than on the ...

Expansionary fiscal shocks and the trade deficit
In this paper, we use an open economy DGE model (SIGMA) to assess the quantitative effects of fiscal shocks on the trade balance in the United States. We examine the effects of two alternative fiscal shocks: a rise in government consumption, and a reduction in the labor income tax rate. Our salient finding is that a fiscal deficit has a relatively small effect on the U.S. trade balance, irrespective of whether the source is a spending increase or tax cut. In our benchmark calibration, we find that a rise in the fiscal deficit of one percentage point of GDP induces the trade balance to ...

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 ...

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 ...

Nominal wage rigidities and the propagation of monetary disturbances
Recent research has challenged the ability of sticky price general equilibrium models to generate a contract multiplier, i.e., an effect of a monetary innovation on output that extends beyond the contract interval. We show that a simple dynamic general equilbrium model that includes "Taylor-style" (1980) wage and price contracts can account for a substantial contract multiplier under various assumptions about the structure of the capital market. Most interestingly, our results do not rely on a high intertemporal labor supply elasticity or elastic supply of capital: our preference ...

Money, sticky wages, and the Great Depression
This paper examines the ability of a simple stylized general equilibrium model that incorporates nominal wage rigidity to explain the magnitude and persistence of the Great Depression in the United States. The impulses to our analysis are money supply shocks. The Taylor contracts model is surprisingly successful in accounting for the behavior of major macroaggregates and real wages during the downturn phase of the Depression, i.e., from 1929:3 through mid-1933. Our analysis provides support for the hypothesis that a monetary contraction operating through a sticky wage channel played a ...
