A global database of domestic and international tourist numbers at national and subnational level

We present a new, global database on tourist destinations. The database differs from other databases in that it includes both domestic and international tourists; and it contains, for the most important destinations, data at national level as well as at lower administrative levels. Missing observations are interpolated using statistical models. The data are freely accessible on the internet. Copyright © 2007 John Wiley & Sons, Ltd.

Sustainable development,the Hartwick rule and optimal growth

Defining sustainable development as non-declining utility, the consistency of this concept with the Hartwick rule and optimal growth is explored when resources are exhaustible. A simple proof that a generalized Hartwick rule is necessary and sufficient for constant consumption is derived. The existence of a maximal constant consumption path is shown to depend critically on the elasticity of substitution; if this is less than 1, consumption declines; if it is greater than 1 then consumption is not maximal; if it is equal to 1 (the Cobb-Douglas case) then existence is proved. Consumption can increase along an optimal path if the pure rate of time preference is 0; if it is non-zero then consumption declines.     

The observable implications of self-fulfilling expectations

Under a modest generalization of the dynamics permitted for variables which are seen by agents but not the econometrician, many of the existing tests for the presence of speculative bubbles are not statistically valid. Less restrictive tests lead us to concur with Flood and Garber that speculative bubbles were not part of the German hyperinflation, but dispute Shiller's conclusion that stock prices are excessively volatile. Moreover, all such tests are subject to the admonition that what appears to be a speculative bubble could instead have arisen from rational agents responding solely to economic fundamentals not observed by the econometrician.     

Application of the Capital Asset Pricing Model to Multi-period Investments

This paper presents a method for evaluating a multi-period asset that is consistent with the valuations implied by the capital asset pricing model, and shows how the results of the valuation processes can be expressed in terms of a number of commonly used valuation formulas.
Ce papier expose tout d'abord une méthode permettant d'estimer une valeur immobilisée à multiples périodes qui soit compatible avec les évaluations fournies par le modéle d'bvaluation de l'actif immobilisé. II montre ensuite comment les résultats des opérations d'haluation peuvent être exprimés au moyen d'un nombre de formules d'estimation couramment utilisées.
Dieser Beitrag stellt eine Methode für die Bewertung einer mehrperiodischen Investition dar, die mit den Bewertungen, die das 'Capital Asset Pricing' Modell impliziert, übereinstimmt. Er zeigt, wie die Ergebnisse des Bewertungsprozesses mittels einer Anzahl gebrluchlicher Formeln ausgedruckt werden konnen.
