This paper presents an assessment of the effects of fiscal policy on economic growth. Starting from a theoretical model in which only those fiscal policy instruments presumed to strictly influence the production process (i. e., public capital and transfers) are incorporated into the production...

This paper examines the impact of infrastructure on productivity in the various regions of Spain. Using the duality approach and panel data, we estimate the regional cost functions for the three main sectors of the economy for the period 1964-1991. We also estimate a production, and two separate...

En este trabajo se examina la manera en que los países miembros de una unión monetaria responden a las perturbaciones específicas y a las que proceden del resto del mundo, cuando aplican políticas de oferta. Desarrollamos un modelo de tres países que muestran preferencias distintas respecto...

In this paper we study possible rankings of opportunity profiles. An opportunity profile is a list of sets of alternative opportunities, one set for each agent in the society. We compare such opportunity profiles on the basis of the notion of "equality of opportunities". Our main results show...

Revisions of US macroeconomic data are not white-noise. They are persistent, correlated with real-time data, and with high variability (around 80% of volatility observed in US real-time data). Their business cycle effects are examined in an estimated DSGE model that distinguishes real-time data...

As one alternative to search frictions, wage stickiness is introduced in a New-Keynesian model to generate endogenous unemployment fluctuations due to mismatches between labor supply and labor demand. The effects on an estimated New-Keynesian model for the U.S. economy are: i) the Calvo-type...

The aim of this research is to model altruistic blood and organ donors behaviour. First, we make an analysis of the decision of to be or not to be a donor for any individual. We propose a model where individuals compare the expected utility of deciding to become a donor, with the utility of the...

Erceg, Henderson and Levin (2000, Journal of Monetary Economics) introduce sticky wages in a New-Keynesian general-equilibrium model. Alternatively, it is shown here how wage stickiness may bring unemployment fluctuations into a New-Keynesian model. Using Bayesian econometric techniques, both...

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool...
