本文针对跨国快餐产业中的成组产品进行分析,区分主要产品与次要产品的搭配模式与价格折扣方式,并透过统计分析与假设检定进行实证检验,以了解搭配模式与折扣方式对消费者购买意愿所造成的影响。实证结果显示:主次产品种类的搭配与价格折扣方式对于消费者购买意愿的影响是显著的,并且两个变量之间存在交互作用效果。此结论为垮国快餐产业在中国市场进行营销时采用成组产品战略提供了支持。 相似文献

本文利用深市基金指数高频数据,采用Anderson和Bollerslev(1997)提出的弹性傅立叶回归(FlexibleFourierFormregression,即FFF回归)方法首次对深市基金市场进行了日内周期性的研究。通过对高频收益的定性分析,发现基金市场具有同股票市场相似的周期性,并对这一周期性进行了初步的理论解释。通过FFF方法,将该周期因子进行滤波处理以后,基金指数高频绝对收益不再具有明显周期性。FFF回归能较好地确定日内周期因子。 相似文献

After more than 50 years of self‐regulation of the US auditing profession, the Sarbanes‐Oxley Act of 2002 (SOX) created the Public Company Accounting Oversight Board (PCAOB) as a quasi‐governmental entity with statutory authority to inspect accounting firms that audit public clients. The frequency of this inspection is annual or triennial, based upon the number of public clients the firm audits. We examine the effects of these two levels of inspection frequency on financial reporting quality and audit fees for clients of small and midsize public accounting firms. Our findings provide evidence of significantly higher audit quality and audit fees for clients of annually inspected firms relative to clients of triennially inspected firms. These findings are robust to auditor‐client alignment analyses, propensity score matching, time‐series analyses, examination of firms that have changed from triennial to annual inspection, and particular examination of firms with inspection deficiencies. Overall, our study suggests that the two‐tier frequency system of PCAOB inspection may have also resulted in two‐tier audit quality and audit fee systems for small and midsize public accounting firms, with more frequent inspection leading to more rigorous and informed auditor decisions. We discuss the implications of our results for the Board and the profession at large. 相似文献

This study evaluates whether the influence of shopping with a companion is consistent across retail contexts with service components or between genders. An experiment asked participants to recall and evaluate their most recent solo or joint restaurant or shopping experience. Results demonstrate that for restaurant experiences, there is a positive influence of others on individual time spent, money spent, satisfaction, and attitude toward the act. For shopping experiences, however, these effects were either strengthened or reversed dependent upon gender. For (males) females, joint shopping experiences are linked to (increased) decreased amount paid, attitude toward the act, and re-patronage intentions. 相似文献

Following recent advances in the non‐parametric realized volatility approach, we separately measure the discontinuous jump part of the quadratic variation process for individual stocks and incorporate it into heterogeneous autoregressive volatility models. We analyse the distributional properties of the jump measures vis‐à‐vis the corresponding realized volatility ones, and compare them to those of aggregate US market index series. We also demonstrate important gains in the forecasting accuracy of high‐frequency volatility models. 相似文献

As offline retailers struggle to compete with online ones, the importance of a consumer’s ability to touch a product prior to purchase becomes important to study. Prior research has found inconsistent results on whether product touch facilitates consumers’ product-related decision making. Some studies report a positive effect, whereas others do not. The current research reconciles this inconsistency and draws retailing implications. Across three experiments, we show that the effect of product touch on consumers’ purchase intentions and willingness to pay for a product being evaluated is evident when consumers’ mental representation of the product is concrete, but not when abstract. We further show that perceived risk and perceived ownership simultaneously mediate this moderating effect of mental representation. Implications are drawn for both offline and online retailers. 相似文献

In this article, we review and discuss the factors, which affect the change in the consumer behavior towards organic food. We extract findings from various studies conducted in different countries and analyze those factors and provide suggestions for future research. We find that health-conscious consumers show a growing preference for organic food over the conventionally grown food. This shift in the attitude of the modern consumers is greatly influenced by the rising incidence of lifestyle diseases, such as heart disorders and depression. The need to purchase organic food to improve the quality of life will have huge implications for the retail, distribution and marketing functions of business. 相似文献

重叠滤波多音(O-FMT)是针对滤波多音(FMT)系统频谱利用率低的缺点而根据超奈奎斯特(FTN)概念引入子载波重叠得到的方案。鉴于O-FMT系统在频偏环境下的性能缺陷,理论分析了频偏对系统信号各部分的影响,比较了O-FMT与正交频分复用(OFDM)系统的抗频偏性能。针对频偏性能优化问题,提出了基于最佳线性无偏估计(BLUE)的改进盲估计算法,设计了基于频域滤波器系数的内嵌结构进行频偏补偿。仿真实验表明,O-FMT相比OFDM具有更好的抗频偏能力,改进的盲估计算法估计值精度更高,抗干扰、抗衰落能力更强,设计的频偏补偿结构可以使系统获得更好的性能。 相似文献
