In an endogenous growth model with human capital acumulation,I discuss the feasibility of a reduction in a marginal tax rate on labor and capital income, given a predeterminated path for government expenditures. A permanent tax cut is feasible if it can be compensated by an increase in the tax...

En este trabajo se presenta el estado actual de conocimiento del problema de la política fiscal óptima, así como hacia dónde se dirigen las líneas de investigación en este área. En particular se describen los principales resultados derivados de cómo un gobierno debería ejecutar la...

This paper presents the state of art in optimal fiscal policy, focusing on the more promising research lines in this topic. In particular, we show the main results on how the government must implement optimal fiscal policy in different frameworks: from static to dynamic stochastic settings and,...

We show that in a simple growth model, where public consumption enters the utility function, and under constant returns to scale in production, the competitive equilibrium can be undetermined. Indeterminacy of equilibria arises for plausible values of the elasticity of intertemporal substitution...

In a previous work, Forner and Marhuenda (2001) find that the contrarian strategy, thatis, the forming of a zero-investment portfolio that buys the stocks that have performed poorly inthe past (losers) and sells those that have performed well (winners), does not yield abnormallypositive returns...

The management of a life insurance portfolio or pension fund must take intoaccount the temporal evolution of its liabilities and its assets through some variables:the factors and returns. Their behaviour is analysed statistically and we deduce it to avector error correction model (VECM). Using...

This study puts forward a procedure for assessing the results of television advertising media plans. It innovates by requiring only information on audience figures for the television media, to determine the distribution of exposures generated by plans using multiple media vehicles and multiple...

This paper analyzes, using a binomial logit model, the factors that determine a students decision on a three or four year University career. The microeconomic model we consider includes the most important aspects of educational choices. The results show how social background, family earnings and...
