We investigate optimal buy-and-hold strategies for terminal wealth problems in a multi-period framework. As terminal wealth is a sum of dependent random variables, each of these variables corresponding to an amount of capital that has been invested in a particular asset at a particular date, we...

The supply of motorways reduces travel time costs by road, affecting thus the demand for road transport. Besides these intramodal effects, there exist intermodal effects too as far as motorways have impact on the demand of the competing modes. In this paper we establish and estimate a model that...

Unemployment is one of the most important problems of the Spanish and European economies. A possible analysis, vastly extended in recent literature, focuses on mismatch problems between labour demand and supply. In this sense, the empirical relationship between the vacancy rate and the...

In this work we revise Levels Models of the Interest Rates in Chile. In addition to the traditional Level Models by Chan, Karoly, Longstaff and Sanders (1992) in the USA, and Parisi (1998) in Chile, by Maximun Likelihood method we allow that the conditional volatility also include the unexpected...

The liberalisation of air transport that took place in the European Union at the beginning of the nineties has involved positive effects on the welfare traveller. However, there is an agreement in the academic literature that such effects depend on the existence of an effective competition at...

The present study evaluates the existence of differences in competitiveness of Spanish industrial firms as a consequence of the district effect. A quantitative analysis has been performed in order to assess external competititveness taking into account whether firms are locates in industrial...

In this work the valuation methodology of compound option written on a downand-out call option, developed by Ericsson and Reneby (2003), has been applied to deduce a credit risk model. It is supposed that the firm has a debt structure with two maturity dates and that the credit event takes place...

In this paper we obtain the expression of the random variable final value of an annuity-due, its mathematical expectation and its variance, considering a stochastic accumulation law based on a Wiener Process. Due to the fact that stochastic accumulation factors are dependent when, temporally...

In this paper we analyze how the composition of labor taxation affects unemployment in a unionized economy with capital accumulation and an unemployment benefit system. We show that if the unemployment benefit system is gross Bismarckian then the unemployment rate is reduced if wage taxes are...

In this paper we estimate, analyze and compare the term structures of interest rates in six different countries over the period 1992-2004. We apply the Nelson-Siegel model to obtain the term structures of interest rates at weekly intervals. A total of 4,038 curves are estimated and analyzed....
