Environment both endowed and built are essential for tourism. However tourism and environment maintains a complex relationship, where in most cases environment is at the receiving end. Many tourism development activities have adverse environmental effects, mainly emanating from construction of general infrastructure and tourism facilities. These negative impacts of tourism can lead to the destr...

The degree distance of a graph which is a degree analogue of the Wiener index of the graph. Let G = TUV C6[2p, q] be the carbon nanotubes covered by C6, formulas for calculating the degree distance of armchair polyhex nanotubes TUV C6[2p, q] are provided. Mathematics Subject Classification: 05C05, 05C12

We consider the problem of testing for seasonal unit roots in monthly panel data. To this aim, we generalize the quarterly CHEGY test to the monthly case. This parametric test is contrasted with a new nonparametric test, which is the panel counterpart to the univariate RURS test that relies on counting extrema in time series. All methods are applied to an empirical data set on tourism in Austri...

This paper analyses from an empirical point of view the relationship between the provision of high-speed rail services (HSR) and the evolution of tourism at the local level in Spain. We have built a database of 124 municipalities during the 2005-2012 period to study the effects of the introduction of new HSR corridors on the number of visitors and their total and average stay at several end-lin...

The effectiveness of economic policies depends on the nature of expectations. Under adaptive expectations, the Philipps curve allows a governement to "surprise" agents. Under rational expectations, there is less room for economic policies. We assume that only an (endogenously determined) proportion of agents form rational expectations and show that this leads the government to optimal policies ...

In this article we discuss the implementation of general one-factor short rate models with a trinomial tree. Taking the Hull-White model as a starting point, our contribution is threefold. First, we show how trees can be spanned using a set of general branching processes. Secondly, we improve Hull-White’s procedure to calibrate the tree to bond prices by a much more efficient approach. This app...

This article derives optimal fiscal rules within a stochastic model of Keynesian type in the context of Poole (1970) analysis. By using optimal control theory and applying the Hamilton-Jacoby-Bellman equation, we extend the original Poole results concerning the output stabilization properties of monetary policy to the case of fiscal policy. In particular, we look for the optimal setting of gove...

This paper introduces a new model of environments with a large number of agents and stochastic characteristics. We consider sequences of finite but increasingly large economies that ‘discretize’ the continuum. In the limit we obtain a model that is continuum-like in important respects, yet it has a countable set of agents with a finitely additive, ‘uniform’ distribution. In this model, the law ...
