We study the evolution of the public debt to GDP ratio during 40 fiscal consolidation episodes in 21 OECD countries in 1980-2008. We test within a multivariate regression framework seven hypotheses put forward in the literature on the success or failure of consolidation programmes. These...

The entry of a new product increases consumer surplus through additional product di- versity but decreases firm profits. In markets where .rm entry intensi.es competition and reduces markups through strategic interactions, we expect entry to be excessively high. In a simple general equilibrium...

We construct an overlapping generations model for an open economy where hours worked, human capital accumulation, income and welfare are all endogenous. Within each generation we distinguish individuals with high, medium or low innate ability. These differences in ability explain inequality in...

This paper takes a fresh look at the issue of foreign aid fungibility. Unlike the bulk of existing empirical studies, I employ panel data that contain information on the specific purpose for which aid is given. This allows me to link aid given for education and health purposes to recipient...

We analyse the in uence of fiscal policy on TFP and per capita output in a panel of OECD countries since 1975. We focus on the effects of government size, government deficits and the composition of taxes and expenditures. Compared to existing studies, our contribu- tion is double. First, we are...

We study the effects of fiscal consolidation within a dynamic general equilibrium model with overlapping generations. Our contribution to the theoretical consolidation literature is threefold. (i) Individual decisions of time allocation between work, leisure and education are fully endogenous in...

This paper examines the government spending multiplier when economic agents form their expectations based on an adaptive learning scheme. The learning mechanism is such that the agents forecast future values of forward-looking variables using a linear function of an information set that does not...

We show that credit market imperfections substantially increase the government-spending multiplier when the economy enters a liquidity trap. This ?finding is explained by the tight association between capital goods and ?rms?collateral, a relationship that we highlight as the capital-accumulation...

We study the effects of pension reform in a four-period OLG model for an open economy where hours worked by three active generations, education of the young, the retirement decision of older workers, and aggregate growth, are all endogenous. Within each generation we distinguish individuals with...

This paper evaluates the effects of a parametric adjustment to an earnings-related PAYG pension system. We show that a simple but ‘intelligent’ reform, in which the calculation of the pension base is changed, may result not only in more employment and growth, but also in an increase in...
