Tourists’ aesthetic assessment of environmental changes,linking conservation planning to sustainable tourism development

Abstract

Tourists often travel to experience the natural beauty of a destination such as the Great Barrier Reef (GBR) in Australia. This nature-based destination attracts millions of tourists every year because of its outstanding underwater aesthetics. Recently, parts of the GBR have been degraded by warming sea temperatures and other local anthropogenic influences, threatening the Reef aesthetics and tourism in the region. In order to deal with this topical issue, the current research investigates tourists’ aesthetic assessment of environmental changes in the GBR ecosystem. Research outcomes indicate that tourists’ perceived beauty of the Reef is sensitive to environmental changes. The disappearance of sea animals (colourful fish, turtle), degrading coral and decreasing water quality negatively influence their aesthetic assessment, which can reduce tourist visitation in the long-term. Hence, sustainable tourism development in the GBR regions can only be achieved when government support for environmental management is strengthened. Conservation programs of the GBR should expand beyond coral restoration for controlling water quality, reducing pollution and protecting aesthetically appealing sea animals.     

Humanising Business Through Ethical Labelling: Progress and Paradoxes in the UK

Labelling schemes are practical arrangements aimed at making ‘ethical’ products widely available and visible. They are crucial to expanded development of ethical markets and hence to the addition of moral dimensions to the normally amoral behaviour linking consumers and retail and production businesses. The study reported here attempts to assess the contribution of UK ethical, social and environmental certification and labelling initiatives to ‘sustainable’ consumption and production. The research sought to assess the overall potential of initiatives to inject human values into the supply-distribution chains, through a qualitative survey of 15 of the 26 main UK initiatives: in social justice, animal welfare and environmental sustainability from the agriculture, food processing, timber, aquaculture, textiles and personal care sectors. By analysing the basic characteristics and concepts of these labels and investigating the emergence of labelling initiatives, we assess whether labels help add an ethical dimension, or whether, in some respects, they also reduce such missions to the technical management of adding only another ‘utility’ to a product. The analysis assesses whether the gradual ‘mainstreaming’ of ethical initiatives such as ‘Fairtrade’ risks subsuming ethical goals within business participants’ competitive and profit-oriented logics. However, the contrasting perspectives revealed between rival labelling initiatives show that the scope and functions of labelling projects go beyond the manifest ones of information communication between consumers and producer and actually introduce elements of socio-political regulation. These are essential for more sustainable and ethical business practices and are an integral part of any humanisation of business involvement.     

A reformulation of the theory of demand by compensated demand functions

We present a formal approach to consumer demand by compensated demand functions. In accordance with the integrability theory or with the theory of revealed preference, we do not require the existence of a utility function, but we do assume certain hypotheses concerning functions describing rational behavior. In view of their properties, these functions can be interpreted as compensated demand functions. According to traditional neoclassical consumer theory, Shephard's lemma and the symmetry and negative semidefiniteness of the Slutsky-Hicks matrix can be shown. We shall also see that a convex, continuous, and monotonic preference ordering, which is representable by income compensation functions, can be introduced. It can also be shown that the existence of a compensated equilibrium can be derived within this approach by compensated demand functions. In order to obtain the existence of a compensated equilibrium under less stringent conditions we finally generalize the axioms assuming that a compensated demand correspondence is given.

On the pricing of forward starting options in Heston’s model on stochastic volatility

We consider the problem of pricing European forward starting options in the presence of stochastic volatility. By performing a change of measure using the asset price at the time of strike determination as a numeraire, we derive a closed-form solution within Hestons stochastic volatility framework applying distribution properties of the volatility process. In this paper we develop a new and more suitable formula for pricing forward starting options. This formula allows to cover the smile effects observed in a Black-Scholes environment, in which the extreme exposure of forward starting options to volatility changes is ignored.Received: July 2004, Mathematics Subject Classification (2000): 91B28, 60G44, 60H30, 60E10JEL Classification: G13It is a pleasure to thank the anonymous referee for his valuable comments and suggestions on this paper.

What and How Long Does It Take to Get Tenure? The Case of Economics and Business Administration in Austria,Germany and Switzerland

Abstract. This paper investigates the determinants of tenure decisions in Germany, Austria and the German‐speaking part of Switzerland for professorships in economics, business administration and related fields. Our dataset comprises candidates who were awarded tenure as well as those who were eligible but were not tenured. We show that business candidates have a higher probability of being tenured than economists. Youth, marital status and publications matter; gender and children do not. The market for first appointments in economics relies much more on publication performance than the market for business administration.     

Tourism and developing countries

The expansion of the tourist industry in developing countries is seen by both the countries themselves and international development organisations as a promising route towards boosting economic development. However, once the benefits and costs to society have been carefully weighed up this route appears very problematic in many cases.
