How much has quantitative "marketing science" contributed to the practice of marketing? In my view, not much. In this article, based on extensive consulting experience, it is argued that well-established quantitative techniques like econometric models and diffusion models have produced little of either practical or scientific value. Other quantitative techniques, such as conjoint analysis, have been more useful for marketing decision-makers. But what is needed is a more pluralistic culture, drawing on a range of complementary disciplines. 相似文献
Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range. 相似文献
Customer loyalty is viewed as the strength of the relationship between an individual’s relative attitude and repeat patronage.
The relationship is seen as mediated by social norms and situational factors. Cognitive, affective, and conative antecedents
of relative attitude are identified as contributing to loyalty, along with motivational, perceptual, and behavioral consequences.
Implications for research and for the management of loyalty are derived.

The article examines some of the key statements of the supply-side economic theory that rejects debt-financed government investment programs for stabilizing high employment. It turns out that supply-side objections are not empirically proven. Subsequently, the author attempts to explain why nevertheless the supply-side paradigm stubbornly remains the prevailing theory in economics. It shows that the mechanisms of deliberative democracy in the economic decision-making in Germany do not work. 相似文献
Monetary budgets influence activity participation and related travel as they demarcate limits on how people organize their activities in time and space. In this paper, we are interested in money allocation to out-of-home leisure activities and how this is affected by duration, sociodemographics, and time-location variables. Analyses were carried out by applying a seemingly unrelated regression model to a leisure activity data set. The analyses revealed that expenditures for out-of-home leisure activities are influenced by the variables mentioned above. Moreover, the results indicate that there is a substitution between expenditure of each activity. 相似文献
Antitrust guidelines rely on structural screens to review horizontal merger proposals for possible anti-competitive effects. This paper extends this screening approach to forecast where industry cartels will form, and where cartel agreements are more likely to raise price. I test the screen's reliability for a unique data set of legal, privately enforced industry cartels that formed under the Webb-Pomerene Export Trade Act. Consistent with screening assumptions, I find that cartels formed more frequently in industries with significant potential market power, high barriers to entry, and conditions facilitating the enforcement of agreements. However, these characteristics generally perform less well at distinguishing when cartels are likely to raise price without generating offsetting cost-savings, suggesting that screening is reliable only as a preliminary check for possible anti-competitive behavior. 相似文献
