This paper develops a dynamic stochastic general equilibrium model with nominal rigidities, capital accumulation and finite lifetimes. The framework exhibits intergenerational wealth effects and is intended to investigate the macroeconomic implications of fiscal policy, which is specified by...

Using vector autoregressions on U.S. time series for 1957-1979 and 1983-2004, we find government spending shocks to have stronger effects on output, consumption, and wages in the earlier sample. We try to account for this observation within a DSGE model featuring price rigidities and limited...

How much did fiscal policy contribute to euro area real GDP growth during the Great Recession? We estimate that discretionary fiscal measures have increased annualized quarterly real GDP growth during the crisis by up to 1.6 percentage points. We obtain our result by using an extended version of...

We introduce a specification of habit formation featuring non-separability between consumption and leisure into an otherwise standard New Keynesian model. The model can be estimated with standard Bayesian techniques and the bond pricing implications are evaluated using higher-order...

I show that the zero nominal interest rate bound may render it desirable for society to appoint a fiscally activist policy-maker who cares less about the stabilisation of government spending relative to inflation and output gap stabilisation than the private sector does. I work with a simple New...

We investigate the macroeconomic effects of fiscal policy using a Bayesian Structural Vector Autoregression approach. We build on a recursive identification scheme, but we: (i) include the feedback from government debt (ii); look at the impact on the composition of output; (iii) assess the...

The United States's post-World War II emphasis on activist fiscal policy for short-term economic stabilization was called into question in the 1960s, and by the late 1980s was superseded by the view that fiscal policy should focus on long-run structural concerns. For the past two decades both...

The NBER Macroeconomics Annual presents pioneering work in macroeconomics by leading academic researchers addressed to a broad audience of public policymakers as well as to the academic community. Each paper is followed by comments and discussion to give a more complete context for the views...

Since 1991, Robert Barro has been a lively contributor to the Wall Street Journal and other popular financial media. Getting It Right brings together, updates, and expands upon these writings that showcase Barro's agility in applying economic understanding to a wide array of social issues....
