We examine the role of money in three environments: the New Keynesian model with separable utility and static money demand; a nonseparable utility variant with habit formation; and a version with adjustment costs for holding real balances. The last two variants imply forward-looking behavior of...

In this paper we look at the interplay between the level of household leverage in the economy and fiscal policy. When the fiscal rule is defined on lump-sum transfers, government spending or consumption taxes, the impact multipliers of transitory fiscal shocks become substantially amplified in...

We study the size of government spending multipliers in a general equilibrium model with search and matching frictions in which we allow for different levels of household indebtedness. The main results of the paper are: (a) the presence of impatient households and private debt helps generate...

The co-movements of labor productivity with output, total hours, vacancies and unemployment have changed since the mid 1980s. This paper offers an explanation for the sharp break in the fluctuations of labor market variables based on endogenous labor supply decisions following the mortgage...

In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using...

In this article we show that the picture emerging from models that allow for generalized parameter heterogeneity in convergence equations changes our view of the convergence process within the OECD. Estimation methods that allow for non- or partial heterogeneity stress the importance of...
