Increasing Consolidation Within the Cruise Line Industry

The cruise industry has become the fastest growing segment of the tourism industry in the 1980Æs. This paper presents an overview of the reasons behind this growth, reviews the current structure of the U.S. cruise line industry, and looks at the future structure of the industry.     

'Classical' Roots of Input-Output Analysis: A Short Account of its Long Prehistory

This paper discusses the roots of input-output analysis in 'classical' economics. The authors considered include Petty and Cantillon; Quesnay, the physiocrats and their critic Isnard; Smith, Ricardo, Torrens and Dmitriev; Marx, von Bortkiewicz and von Charasoff; Leontief; and Remak. It is argued that, in terms of method and content, input-output analysis is akin to the classical approach to the theory of production, distribution and relative prices in that (i) it requires all magnitudes to be observable and (ii) starts essentially from the same set of data. It is shown that many important modern concepts have been anticipated by the earlier authors. The prehistory of input-output analysis is also meant to provide new perspectives on potential future developments of the field.     

Realizing new regional core competencies: establishing a customer-oriented SME network

This paper explores the possibilities of combining the recently developed ‘value constellation’ concept and the literature about industrial districts. The advantages related to the geographical concentration of economic activities are insufficient in the competition with companies that are linked to each other within a value constellation - a customer-oriented inter-organizational strategy. This new type of competition forces traditionally operating SMEs in industrial districts to team up with each other in a customer-oriented network. However, these networking strategies are unlikely to emerge because SMEs are locked into their traditional competencies and they lack the financial and strategic resources to develop interactive strategies covering the entire value system. Business associations and local institutions may play a crucial role in changing and shaping the emerging network among the SMEs. However, local institutions are equally susceptible to being locked into traditional patterns of interaction. Their willingness to break away from the past is crucial for the learning capabilities of local SMEs. The difficulties in setting up a customer-oriented network are illustrated by the ‘construction and home furnishings’ business cluster in South West Flanders (Belgium).     

Efficient and accurate quadratic approximation methods for pricing Asian strike options

This study is on valuing Asian strike options and presents efficient and accurate quadratic approximation methods that work extremely well, both with regard to the volatility of a wide range of underlying assets, and longer average time windows. We demonstrate that most of the well-known quadratic approximation methods used in the literature for pricing Asian strike options are special cases of our model, with the numerical results demonstrating that our method significantly outperforms the other quadratic approximation methods examined here. Using our method for the calculation of hundreds of Asian strike options, the pricing errors (in terms of the root mean square errors) are reasonably small. Compared with the Monte Carlo benchmark method, our method is shown to be rapid and accurate. We further extend our method to the valuing of quanto forward-starting Asian strike options, with the pricing accuracy of these options being largely the same as the pricing of plain vanilla Asian strike options.     

Advertising value and advertising processing

Advertising value research is rooted in the view that advertising messages are potential communications exchanges between advertisers and consumers. Since some level of processing effort on the part of receivers is necessary for successful exchanges to occur, it is proposed that advertising processing decisions are based on initial, spontaneous, categorical evaluations that combine to form an expected advertising value (EAV) assessment. If sufficiently positive, individuals devote additional processing effort to the advertisement and more detailed ad-related factors become the focus. Once processing ends after some or all of an advert has been taken in, an evaluation of whether or not the effort was actually worthwhile - designated as outcome advertising value (OAV) - should be a measurable outcome. Factors that account for OAV and its relationship to attitude-toward-the-advertisement (A ad ) are also discussed.

Environmental concern and environmental behaviour among the Norwegian public

Current studies indicate that the most accurate predictor of actual buying behaviour is consumer attitudes (Glendon and McKenna, Human Safety and Risk Management , London: Chapman and Hall, 1995). This study seeks to investigate questions relating to the extent to which attitudes on safety and risk issues are critical to safety-related behaviour. The dispositional view of human behaviour implies behavioural consistency across different behaviours performed in different situations, as long as the behaviours are instances of the same underlying disposition. The present study tests this hypothesis in relation to health and environmental behaviour. Both direct and indirect effects are investigated. An additional aim was to test for gender differences as well as differences due to age and educational level. The results are based on survey data of a representative sample of the Norwegian population given self-completion questionnaires during the period 1997-98. A total of 1450 respondents replied to the questionnaire. Health attitudes and the Health Value Scale correlated strongly with health behaviour and environmental concern with environmental behaviour. Attitude towards illness prevention was important for both behavioural dimensions. Health behaviour influenced environmental behaviour in an indirect way, through health attitudes. The results imply that it can be useful to study dispositional concepts. When appropriately applied, they yield useful information. It is important to focus on specific attitudes and related specific behaviours in order to change behavioural practices. In addition, it seems possible to change environmental and consumer behaviour through changing health
