Tourism and transport represent two sides of the same management process, especially in tourism destinations characterised by a consistent or a rising volume of visitor flows.

Let the column vectors of X:: M-N, MN, be distributed as independent complex normal vectors with the same covariance matrix [Sigma]. Then the usual quadratic form in the complex normal vectors is denoted by Z=XLXH where L: N-N is a positive definite hermitian matrix. This paper deals with...

Consider the quadratic form Z=YH(XLXH)-1 Y where Y is a p-m complex Gaussian matrix, X is an independent p-n complex Gaussian matrix, L is a Hermitian positive definite matrix, and m[less-than-or-equals, slant]p[less-than-or-equals, slant]n. The distribution of Z has been studied for over 30...

In this paper we solve two open problems posed by Joe (1997) concerning the supermodular order. First we give an example which shows that the supermodular order is strictly stronger than the concordance order for dimension d=3. Second we show that the supermodular order fulfils all desirable...

We modify the altruistic model by assuming that income, instead of the heir's utility, enters the altruist's utility function. We name this formulation "myopic" because, unlike in Barro's (1974) model, the altruist does not need to foresee into the indenite future to make his decisions. We...

A hierarchic price is a finite ordered family of price vectors {p1,...,pk}. It extends the notion of exchange values proposed by Gay (1978). These price notions were introduced in order to establish the existence of a competitive equilibrium without the strong survival assumption. It is well...
