This paper studies the role of automatic stabilizers using a sample of OECD countries and US states. We find that there is a strong and robust negative correlation between measures of government size and the volatility of output. This correlation is robust to the inclusion of a large set of...

In this paper we develop a stochastic dynamic general equilibrium model of the Greek economy, in the real business cycle modelling tradition. Household preferences depend on private and public consumption and leisure. Government finances its investment, consumption and transfer payments by means...

This paper examines the optimal reaction of fiscal policy to permanent and transitory shocks to output in a model of tax and public consumption smoothing. The model predicts that optimal reaction of public expenditures and deficits to transitory shocks should be countercyclical, while optimal...

This Paper identifies optimal interest-rate rules within a rich, dynamic, general equilibrium model that has been shown to account well for observed aggregate dynamics in the post-war United States. We perform policy evaluations based on second-order accurate approximations to conditional and...

In traditional Keynesian and neoclassical models, the transmission of product demand changes to the labour market generally involves wage-price sluggishness or counter-cyclical real wage movements. In practice, however, real wages are often acyclical or procyclical, and wages and prices are...

This paper develops a model of job creation and job destruction in a growing economy with embodied technical progress, that we use to analyze the political support for employment protection legislations such as the ones that are observed in most European countries. We analyze the possibility of...

After a brief review of the main differences between New and Old Keynesian economics from the 1960s this paper focuses on a tension between traditional sluggish measures of potential output commonly used by policy-makers and the New Keynesian (NK) notion of this variable which conceptualizes it...

The paper discusses some fundamental problems in monetary economics associated with the determination and role of the numéraire. The issues are introduced by formalising a proposal, attributed to Eisler, to remove the zero lower bound on nominal interest rates by unbundling the numéraire and...

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy-making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

How to use an unexpected increase in tax revenues (tax pots) has been an important issue in most OECD countries in the second half of the 90’s, the question being more precisely what to do with those windfall revenues: decreasing taxes, debt, increasing expenditures? In this paper, we study...
