WARRANT PRICING USING OBSERVABLE VARIABLES

The classical warrant pricing formula requires knowledge of the firm value and of the firm‐value process variance. When warrants are outstanding, the firm value itself is a function of the warrant price. Firm value and firm‐value variance are then unobservable variables. I develop an algorithm for pricing warrants using stock prices, an observable variable, and stock return variance. The method also enables estimation of firm‐value variance. A proof of existence of the solution is provided.     

Designs for estimating an extremal point of quadratic regression models in a hyperball

This paper is devoted to studying optimal designs for estimating an extremal point of a multivariate quadratic regression model in the unit hyperball. The problem of estimating an extremal point is reduced to that of estimating certain parameters of a corresponding nonlinear (in parameters) regression model. For this reduced problem truncated locally D-optimal designs are found in an explicit form. The result is a generalization of the results of Fedorov and Müller (1997) for onedimensional quadratic regression function in the unit segment. Received February 2002     

System dynamics modelling and forecasting health tourism demand: the case of Russian resorts

This article presents the results of the system dynamics modelling of the regional market of health tourism in the Krasnodar region of Russia. The research was based on various indicators characterizing the supply and demand for this type of tourism for years 2006–2012. The medium-term forecast made by constructed model shows a possible decrease in number of health tourists and income of sanatorium organizations. Price competition of inexpensive foreign resorts was a key factor influencing the market of tourist services; therefore ruble devaluation to US dollar may improve the prognostic indicators.     

Sodium content in foods: Brazilian consumers’ opinions,subjective knowledge and purchase intent

This study attempted to gain insights on Brazilian consumers’ subjective knowledge of sodium content in processed and homemade foods and their purchase intent for products with reduced‐sodium content. A questionnaire was distributed to 409 consumers selected by convenience quota sampling. We found that Brazilian consumers were concerned about the amount of salt (sodium chloride) in the products they consumed, regardless of educational levels, income, age, lifestyles, or health conditions. However, they still considered their consumption to be above WHO‐recommended limits and had little subjective knowledge about the term ‘sodium’. While processed products were considered the main contributors of high‐sodium intake, participants were not concerned about addition of salt at the table and salt in homemade food. The majority of respondents rarely read the sodium content on food labels; however, men and older individuals were more likely to read label information on sodium content. Products with reduced sodium were found to have market appeal, which justifies investments in research to develop these products. Therefore, in addition to the efforts to reduce sodium in the processed‐food industry, it is necessary to promote awareness about the importance of food labelling, especially sodium content, and the need to reduce salt in homemade food and additions during meals.     

Long-term trends in weather-related crash risks

This study explores whether automobile travel during inclement weather has become more or less risky over the past two decades. The analysis is based on the integration of two government databases and a matched-pair framework for comparing casualty rates under different weather conditions for 10 Canadian cities. The most notable result is a downward trend in relative risk during rainfall from 1984 to 2002 – both overall and when further disaggregated by injury severity combined with precipitation amount, city group, and time of day. By contrast, the overall relative risk of casualty during snowfall shows no significant change over time.

Subprime Lending and Real Estate Prices

This article establishes a theoretical and empirical link between the use of aggressive mortgage lending instruments, such as interest‐only, negative‐amortization or subprime mortgages, and the underlying house prices. Such instruments, which come into existence through innovation or financial deregulation, allow more borrowing than otherwise would occur in previously affordability‐constrained markets. Within the context of a model with an endogenous rent‐buy decision, we demonstrate that the supply of aggressive lending instruments temporarily increases the asset prices in the underlying market because agents find it more attractive to own or because their borrowing constraint is relaxed, or both. This result implies that the availability of aggressive mortgage lending instruments magnifies the real estate cycle and the effects of fundamental demand shocks. We empirically confirm the predictions of the model using recent subprime origination experience. In particular, we find that regions that receive a high concentration of aggressive lending instruments experience larger price increases and subsequent declines than areas with low concentration of such instruments. This result holds in the presence of various controls and instrumental variables.     

Types of Word-of-Mouth Messages: Information Search and Credence-Based Services

Word-of-mouth communication (WOMC) has been recognized as a powerful marketing communication medium and a credible information-gathering tool. To date, the various types of WOM messages have not been adequately studied, especially in credence-based services (CBS). Using the individual interview technique, this study fills this gap by describing the three types of WOMC messages in CBS information-gathering. The results contribute to the ongoing development of WOMC theory and also advance management's understandings of the types of WOMC messages in the CBS information-gathering process.     

VOLUNTARY DISCLOSURE OF SEGMENT INFORMATION: FURTHER AUSTRALIAN EVIDENCE

This study provides further empirical evidence on incentives for Australian firms to voluntarily report segment information. Various economic reasons why firms may elect to present segment information have been hypothesised in previous research. Bradbury [1992] and McKinnon and Dalimunthe [1993] found firm size, minority interest and industry membership as significant identifiable characteristics motivating voluntary segmental disclosure. Variables found to be insignificant in Bradbury [1992] which were not examined by McKinnon and Dalimunthe [1993] are tested in this paper. Hypotheses relating to size, financial leverage, assets-in-place, earnings volatility, ownership diffusion, outside equity (minority) interest, overseas association as well as diverse and mining and oil classification hypotheses are empirically examined. Univariate tests and multivariate logit analysis suggest that for a extensive sample of diversified firms, voluntary segment disclosure is significantly related to size, leverage and involvement in mining or oil activities.
