The effects of sales promotion strategy,product appeal and consumer traits on reminder impulse buying behaviour

This article investigates factors of marketing communications and consumer characteristics that induce reminder impulse buying behaviour. Study 1 applies the antecedent, process and consequence approach to investigate the essential differences between reminder impulse buying and pure impulse buying. The results of Study 1 reveal that reminder impulse buying significantly differs from pure impulse buying on motivation, buying goal and decision evaluation. Study 2 further examines how sales promotion strategy might affect reminder impulse buying, with product appeal and consumer traits as moderating factors. Both sales promotion strategy and its interaction effects with product appeal are found to have significant influences on reminder impulse buying. Specifically, an instant‐reward promotion promotes stronger reminder impulse buying than a delayed‐reward promotion. Furthermore, both a utilitarian product appeal with a price discount promotion and a hedonic product appeal with a premium promotion can encourage greater reminder impulse buying.     

Overeducation and Undereducation and their Effect on Earnings: Evidence from Hong Kong, 1986–1996

The expansion of the higher education sector and the structural changes in the Hong Kong economy in the late 1980s raise the issue of the incidence of overeducation in the Hong Kong labor market. Using the 1991 Hong Kong Census, and the 1986 and 1996 Hong Kong By‐census data, the present study finds that the incidence of overeducation in Hong Kong is only a temporary phenomenon. The rate of return to education increased, while the premium to overeducation decreased, between 1986 and 1996. It also finds that there is a tradeoff relation between education and experience.

Diffusion of mobile telephony: An empirical study in Taiwan

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.     

股市波动、金融政策和宏观经济关系研究——基于因子VAR模型

通过因子分析从诸宏观经济变量中提取了金融政策因子和宏观经济状态因子,建立了基于VAR的股价波动、金融政策和宏观经济三变量回归模型。研究表明：金融政策影响股价的表现,而宏观经济状态对股价、股价对金融政策和宏观经济状态的影响均不显著;基于标准差的VAR（5）模型相对于基于收益率的VAR（3）模型能更好地刻画股市波动与金融政策、宏观经济三者之间的关系。     

Optimal policies for sin goods and health care: Tax or subsidy?

In this paper, we examine the optimal policies for sin goods and health care in a two-period economy. Individuals are myopic in the sense that they undervalue the utilities of future consumption and health quality. When investing in health care in the second period, individuals who have previously made myopic decisions may persist in their shortsighted consumption plans (persistent error) or recognize their mistakes (dual self). We show that, for persistent-error myopes, the first-best policy mix requires a subsidy on savings and a tax on sin goods. The health care should be taxed (subsidized) if the degree of myopia concerning future consumption is larger (smaller) than that concerning health quality. For dual-self myopes, the optimal policy for sin goods can be either a tax or a subsidy, depending on the relative degrees of myopia and the property of the health quality function.     

情感计算的信息隐私法律风险及其应对

情感计算是指以人类情感为机器学习对象，具有情感识别和情感分析功能的智能科技。情感计算不以信息主体的身份识别为前提，旨在通过对输入端生物反馈信息或状态的分析处理而输出情感信息。为应对情感信息不当获取与利用所带来的情感操纵风险，需以信息隐私理论为框架展开风险应对之探讨。然而，现行信息隐私规范却存在风险应对不足的问题。情感信息因其具体类型的多样性而难以划入敏感个人信息的保护范围；生物反馈信息因其情感识别而非身份识别的目的难以作为生物识别信息而被保护；作为信息处理之合法性基础的告知同意也因情感信息的特殊性存在被架空的风险。鉴于欧盟《人工智能法案（草案）》中规制情感识别的经验，我国可尝试在算法治理中构建“生物数据”的概念并以之为媒介展开技术风险的分级分领域规制，从而构建可信赖情感智能的数字环境。
