We examine the impact of fiscal policy interventions in an environment where the short term nominal interest rate is at the zero bound. In the basic New Keynesian model in which the monetary authority operates a Taylor rule, globally multiple equilibria arise, some of which display all the...

We evaluate the extent to which a dynamic stochastic general equilibrium model can account for the impact of "surprise" and "anticipated" tax shocks estimated from U.S. time-series data. In U.S. data, surprise tax cuts have expansionary and persistent effects on output, consumption, investment...

This paper proposes a theoretical explanation of the empirical finding that private consumption increases in response to an increase in government spending. The explanation requires two ingredients. First, labor demand expands (e.g. prices are sticky). Second, general non-separable preferences...

We study the effects of government spending by using a structural, large dimensional, dynamic factor model. We find that the government spending shock is non-fundamental for the variables commonly used in the structural VAR literature, so that its impulse response functions cannot be...

This paper examines the relationship between fiscal policy and the current account, drawing on a larger country sample than in previous studies and using panel regressions, vector auto-regressions, and an analysis of large fiscal and external adjustments. On average, a strengthening in the...

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...

The currently available empirical evidence shows remarkable differences between various estimates of the effects on U.S. output of an exogenous shift in Federal tax liabilities. Shocks identified via the narrative method imply a multiplier of about three over an horizon of three years. Tax...

Foreign aid has been on a downward trend since at least the early eighties. Despite the commitments of donor governments, the GDP share of foreign aid for DAC countries has fallen to slightly more than 0,2% in the early part of this decade. The purpose of this paper is to explore the macro...

This Paper provides a study of bond yield differentials among EU eurobonds issued between 1991 and 2002. Interest differentials between bonds issued by EU countries and Germany or the USA contain risk premia which increase with the debt, deficit and debt-service ratio and depend positively on...

A single variable describes, day-by-day, what investors think about the state of Brazil's economy: the Brazilian component of the Emerging Market Bond Index, the Embi spread. This spread is the difference between the yield on a dollar-denominated bond issued by the Brazilian government and a...
