How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

This paper uses a two country DSGE model to examine the effects of tax-based vs. 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...

Recent research has found that the dynamic properties of the New Keynesian model are unorthodox when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large....

We show that with intertwined weak banks and weak sovereigns, bank recapitalizations become much less effective. We construct a DSGE model with leverage constrained banks lending to firms and holding domestic government bonds. Bond prices reflect endogenously generated sovereign risk. This...

The extent of government deficits and debt has been one of the most debated issues in recent years. However, very little has been contributed about their dynamics . Yet, the issue of entering into and exiting from excessive deficits will be critical in the European monetary union since the...
