Sample bias in contingent valuation: A comparison of the correction methods

Abstract

This article compares various methods for correcting contingent valuation aggregate benefits when the sample is known to be biased. A sample is defined as the population, and response rates are simulated on the basis of a measure of salience. The simulated response rates suffer from nonresponse bias and selection bias. Coefficient and benefit estimates that result from weighting and self‐selection correction approaches are compared with the true coefficient and benefit estimates. Our results indicate that at both low and high response rates the standard approach leads to bias, and either correction approach will reduce the bias in coefficient and benefit estimates.     

Thailand as a tourist destination: Perceptions of international visitors and Thai residents

In the tourism industry, the perceptions of a tourist destination are critical to its image. Image can be either a mental image of a product created by a marketing department or an associative image of a product that is developed by the consumer. Tourism destinations must be careful about their image so the perception that they have is not different from the way that they are perceived by potential travelers. This study examines the perceptions of international visitors and Thai residents on the image of Thailand as a tourist destination. International visitors and Thai residents were both surveyed to determine their perceptions of the image of Thailand. Some results of the study found that Thai residents and international visitors felt cultural sightseeing, friendly people and food were significantly important when thinking of Thailand as a tourist destination, while international visitors felt that nightlife and entertainment were significantly more important than that of Thai residents.     

Tourism in Scotland—under new management

Scotland's tourism product has its own national identity which is derived from the distinctive character of the country's climate, culture, tradition, and industrial and social history. In this report John Stuart, Director of External Relations at the Scottish Tourist Board, describes the new techniques that have been devised to manage the tourism industry in Scotland and promote its product in the UK and overseas.     

An empirical model of attendance factors at major sporting events

Sports events represent a major category of event revenue contributing economic benefits to cities and regions. Whilst attendance at sports events is recognised as an important leisure and entertainment activity (Shamir and Ruskin, 1984), over the past 20 years sports event attendance expenditure has been declining as a percentage of total recreation expenditure (Ross, 2006). Consequently, an understanding of the factors that influence sports event attendance is crucial to the sustainability of these events. This study identifies the antecedents of sports event attendance among 460 respondents who were surveyed in Melbourne, a city that was recognised as the Ultimate Sports City in 2008 (Church-Sanders, 2008). Structural Equation Modelling was used to create an empirical model of attendance motivations. The model identifies constructs relating to emotional responses and facilities, as the predictors of event attendance and provides a discussion of the implications of this research for sporting event and hospitality managers.     

In the mirror of the market: The disciplinary effects of company/fund manager meetings

This paper draws upon empirical qualitative research with Finance Directors and Investor Relations managers to examine the disciplinary consequences of their meetings with institutional investors. These ‘private’ meetings have increased both in frequency and importance in the last decade, but, when compared to public disclosure, they are relatively under researched. Existing studies have focussed on the role that the meetings play either in the market for information, or as a mechanism for corporate governance. By contrast, in this paper we draw upon Foucault’s analysis of power/knowledge to explore how the meetings shape executive subjectivity. The meetings take place in the context of a proliferation of techniques through which corporate performance is disclosed, modelled, compared and ranked. Such visibility makes possible processes of executive subjection which the paper traces firstly in the anticipatory self-discipline of executive’s extensive rehearsals for the meetings, and secondly in the rituals of face-to-face scrutiny of the meetings themselves where the body of the executive is understood to represent the company. The paper then explores the ways in which subjection to investors enables executives to speak on behalf of the investor within the business and effect its restructuring in the name of shareholder value. We suggest that these neglected disciplinary effects of company/fund manager meetings have been all too potent in recent years.     

Informed Traders and Price Variations in the Betting Market for Professional Basketball Games

This paper examines betting line changes from the opening to the closing of the point spread betting market on National Basketball Association games for evidence of informed trader betting. We show that within-betting period line changes significantly improve the accuracy of betting lines as forecasts of game outcomes. We examine individual line change magnitudes and show that these are directly and proportionately related to biases in opening lines. Further, line changes are of sufficient magnitude to remove these biases by the close of betting. We interpret these results as evidence that informed traders are influential in this market.     

A generalized lot sizing model for the process cycling problem

Most scheduling/lot sizing models for the single-machine problem assume that aggregate demand equals aggregate production; and that backorders are to be avoided. Where working inventories are low, the scheduler may wish to avoid short production runs and willingly incur some backorder penalties so as to increase the length of production runs and reduce setup costs per unit of time. The model proposed here identifies optimal lot sizes with respect to the backorder/setup cost relationships. Use of the model will result in an optimally balanced inventory even when aggregate inventory levels are changing.     

The financial health of voluntary hospitals in interwar Britain

This article re–evaluates the gravity of the financial problems facing British voluntary hospitals in the interwar period. A relational database of statistics on hospital provision, finance (at both current and constant prices), and activity is used to derive consistent sets of hospitals for reporting purposes. The article presents novel analyses of the extent and pattern of hospital surpluses and deficits; of the capital accounts of selected individual hospitals; of trends in hospital expenditure; of the diversification of hospital income, emphasizing the declining importance of traditional philanthropy; and of the effect of these changes on hospital provision and utilization.     

Equilibria of price-setting and quantity-setting duopolies

The relation between equilibria of output-setting and price-setting duopolies is investigated using the Inverse Function Theorem. The region that equilibria of the former occupy in relation to equilibria of the latter is found. A minimum of assumptions about the market functions are made.     

The computer imperative

“The Computer Imperative” has been defined as the necessity for the administrator to specify his goals, objectives, criteria, standards, rules, etc., in very explicit and operational terms as he seeks to devise a better management system, especially if computers will be used to implement portions of the system. It is essential that educational leaders be able to tell system designers and computer technologists what they want, and to do this they must know at least the rudiments of what is technically possible. Otherwise, the administrator in some sense is at the mercy of the technologist. Studying an administrative system as essentially an information system provides a useful model. To define who originates, processes, uses, or needs information is to describe much of the actual operation of administration. In a manual system, many rules and procedures can be left undefined, and intuition and experience can substitute effectively for logical precision. As computers are programed to assume certain basic transactional functions, the administrator must bear in mind that computers do only what they are told. It is therefore critically important to be able to describe what we want. Much of the “threat” of automation can be attributed to uneasy or uncomfortable recognition of this “imperative”.
