The influence of advertising on the demand for chocolate confectionery

This paper addresses the impact of advertising on the size of five European chocolate confectionery markets: Belgium, France, Germany, the Netherlands and the UK. It is prompted by suggestions that advertising may be responsible for excessive consumption of confectionery by children. The literature on whether advertising affects the total market size is not one-sided but the balance of previous research indicates market effects to be less likely. Chocolate confectionery in Western Europe is a mature market in slow decline. We found no significant association between the weight of advertising and market growth with either contemporaneous or lagged effects. There was, however, negative correlation between market size and price, as was to be expected. The results were consistent across the five countries.     

Are tourism impacts low on personal environmental agendas?

This paper examines if tourism is an environmental priority for tourism and hospitality students. It is framed within the context of information and choice overload that may result in the need to prioritize issues and make less effective decisions. A series of open-ended questions identified the most important community and global environmental issues, the single greatest cause of climate change and whether students had changed their behaviour in general, or their travel behaviour in particular, to reduce their environmental impact. A total of 2968 useable surveys were returned from students at 63 institutions in 22 economies. Tourism emerged as a low priority issue, which explains why only a small proportion of students had changed their travel behaviour. Moreover, the study noted high knowledge variability, which in turn was closely associated with the type of actions undertaken. Students with specific knowledge were far more likely to adopt specific change actions than those who had less precise knowledge. They, in turn, were more likely to identify generic and less effective actions. The study concludes that the main challenge involved in changing tourism behaviour rests primarily with raising its status to a higher priority, a difficult task given the environmental issue overload that most people face.     

An Analysis of the Deposit-taking Market of Hong Kong

This paper analyzes the deposit-takingmarket in Hong Kong prior to the deregulation ofinterest rates in 1994. We argue that bankingregulations, in the forms of branching restrictionsand interest-rate ceilings, had created amonopsonistic market for short-term bank deposits. Asa result, banks in Hong Kong had earned asubstantially wider interest-rate margin than banks inother Asia-Pacific countries and the United States. We provide procedures to estimate the economicsignificance of the foregone interest and find themonopsonistic rent to be in the order of 1% of theGross Domestic Product of Hong Kong for the period1987 through 1994.

Predicting mispricing of initial public offerings

This article investigates the ability of neural network models to predict mispricing of initial public offerings (IPOs). The aim is to improve the modest explanatory power of existing models that are based on the theory of asymmetrically informed economic agents surrounding post‐issue market value of IPOs. This study develops and compares linear regression and neural network models. The results show that modelling variable interactions and non‐linearity allows a potentially fruitful approach for stagging in IPOs. Neural networks have been criticized for being a black box; however, this paper shows that, by using sensitivity analysis, neural networks can provide a reasonable explanation of their predictive behaviour and direction of association between variables.
