We find that information leakages prior to public guidance issued by company management exist even after Regulation Fair Disclosure (FD), and are more pronounced when characteristics of the firm, the guidance, or the industry reflect higher levels of information asymmetry. Since public guidance is only partially leaked, this information leakage can be used to anticipate the information content of the impending public guidance. We simulate a trading strategy based on the preguidance leakage in the period after Regulation FD, which suggests that information leakage is an effective signal of the information content within impending public guidance. 相似文献

Valuation of Landmass Degradation Using Fuzzy Hedonic Method: A Case Study of National Capital Region 总被引:3,自引:0,他引:3
Rakesh Paliwal Gejo Anna Geevarghese P. Ram Babu P. Khanna 《Environmental and Resource Economics》1999,14(4):519-543
A Hedonic model to determine the revealed willingness to pay for landmass of different suitability classes, based on landmass functional characteristics obtained through subjective assessments, is developed for the National Capital Region in India. The inherent non-specificity involved in subjective evaluation is minimized using fuzzy logic based regression technique. The proposed fuzzy regression involves regression using central values of triangular fuzzy number and minimization of non-specificity using linear programming. The revealed willingness-to-pay for landmass of different suitability classes is used for valuation of disbenefits due to urban expansion on landmass of different agricultural suitability classes in National Capital Territory of Delhi. Appropriate pricing policies to prevent the future inappropriate landuse practices are developed using the landmass valuation. 相似文献

Strategic Goals and Practices of Innovative Family Businesses 总被引:1,自引:0,他引:1
Joseph E. McCann III Anna Y. Leon-Guerrero & Jonathan D. Jr. Haley 《Journal of Small Business Management》2001,39(1):50-59
A profile of 231 Washington state family businesses is presented. This article focuses on the business strategies of these firms, analyzing the relationship between strategy, performance, and business practices. Firms categorized as Prospector firms reported more gains in their current market position than all other strategic types. These firms were more likely to value an effective management and employee team and to develop new quality products and services and career development plans for non-family employees. Implications for family businesses are discussed. 相似文献

Earthquake effects on tourism in central Italy 总被引:2,自引:0,他引:2
This paper proposes an approach to economic assessment of the impact on tourist flows of the earthquake that hit the Umbria region in Central Italy on September 26, 1997. Local arrivals in Assisi fell drastically the month following the main shock, compared to the same month of the previous year. The event study methodology, frequently applied in finance, is employed to evaluate the statistical relevance of the shock over time and space. A further and straightforward application of the event study analysis assesses the substantial amount of loss between October 1997 and June 1998 due to the drop of tourism business. 相似文献

Some recent papers have studied data from TV game shows to examine the behaviour of individuals towards risk. It is generally agreed that data from these shows are useful in detecting individual risk aversion in the field, with both “real life” subjects and incentives. Field experiments also include some interesting reality features that could affect individuals’ behaviour and possibly lead to different findings. This paper aims at investigating lab versus field evidence in risk taking attitudes, especially controlling for framing effects. To assess whether the behaviour of subjects in the field is consistent with that of experimental subjects, we designed an experiment to mimic (with experimental rewards and subjects) the rules of a well-known Italian TV game show, Affari Tuoi, in two different settings: a traditional lab setting, where the game was played individually (109 subjects) (Treatment 1); and a framed lab, in which the experiment was replicated in the Italian public television (RAI) studio where the show was actually recorded, with a smaller sample of undergraduate students (33) and in the presence of an audience (Treatment 2). Our comparison between the two different settings aims at establishing whether the presence of an audience, or of a situation that reproduces the stress that contestants must experience in the TV studio, can affect experimental subjects’ choices. We did not find any significant evidence of framing effects: students behave in a similar way in the two lab settings, responding essentially to incentives. Comparing the risk attitudes shown by experimental subjects in the two lab treatments with those exhibited by the contestants in the field, we found that contestants in the TV show are generally more risk averse than students in the lab. 相似文献

In this paper, we examine the determinants of household consumption of newspapers and the amount spent on their purchase by considering several explanatory variables related to household characteristics and the main household wage earner. Results show that the variables have quite similar effects on both the relative probability of buying newspapers and the amount spent. The key variables are the age and occupational status of the main wage earner, the number of household members, income and having to pay for the house, as well as a number of geographical variables. However, certain differences are also observed. The most important is the education of the main wage earner: while its effect on buying newspapers is very small (only those who did not complete primary education are less likely to buy), its effect on the amount spent increases with the level of education. As other studies of cultural goods and services consumption have suggested, education and occupational status are more relevant determinants than income. 相似文献

Empirical research provides evidence for exchange rates overreaction to changes in economic fundamentals over a short run, but convergence in a long run. In this research we use statistical method developed by Cox [Cox, D.R., “Regression models and life-tables,” Journal of the Royal Statistical Society. Series B (Methodological), Vol. 34, Iss. 2 (1972), 187-220.] to examine the differences in the effects of local economic fundamentals on the probability of occurrence of extreme fluctuations in exchange rates over time periods of rising and falling exchange rates. We identify an extreme fluctuation as a 10% decrease or increase in exchange rate over a three month period and 20% over a one year period. We find asymmetry in the effects of economic fundamentals on exchange rates (eight countries' exchange rates quoted as f/$) during time periods of rising and falling exchange rates: the probability of extreme fluctuation is greater during time periods of rising exchange rates as compared to falling. 相似文献
