The Moderating Effects of Status-Consumption Motive and Age in the Relationship between CSR Advertising Appeal Type and Purchase Intentions

The primary purpose of this study was to examine factors that influence the effectiveness of benefit appeal types (i.e., help-other vs. help-self) in Corporate Social Responsibility advertising. To that end, we designed and administered a between-subjects experiment where participants viewed one of the two CSR advertisements crafted with help-self and help-other benefit appeals. Results provided evidence supporting the moderating effects of status-consumption motives and age on purchasing intentions. Additional analysis suggested consumers younger than 48 years old were more likely to be persuaded by a help-other ad appeal when they didn't have strong desires for status consumption. Results were discussed in light of the self-concept theory and value-expressive framework in CSR advertising.     

Modelling demand for lotto using a novel method of correcting for endogeneity

Modelling lottery sales as a function of the mean, standard deviation and skewness of the probability distribution of returns potentially gives insights into how the design of a game could be modified to maximise net revenue. But use of OLS is problematic because the level of sales itself affects values of the moments (and insufficient instruments are available for IV regression). We draw on the concept of a rational expectations equilibrium, developing a new regression model which corrects for endogeneity where the causal impact of the dependent variable on the right-hand side variables is deterministic. We apply the model to data on lotto sales from Spain. Using the Spanish data, we show that results provide more reliable guidance to lottery agencies because accounting for endogeneity leads to significantly different results from OLS and these results have superior performance in out-of-sample forecasting of sales. More generally, results prove consistent with the Friedman-Savage explanation of why people buy lottery tickets and with evidence from racetrack data that ‘bettors love skewness’.     

Are high–frequency traders informed?

Are high–frequency traders (HFTs) informed? To address this question, we examine HFTs' activity in the call auction environment, where speed-related trading is limited and signal processing capacity becomes more relevant. To model the call market, we consider the Kyle (1989) rational expectations framework for strategic trading. The test we propose for detecting informed HFTs in this market assesses potential deviations of the informativeness of HFTs' aggregate (net) demand, from the informativeness of the aggregate demand submitted by the rest of the traders. Data from the Euronext Paris preopening phase indicate that informed HFTs are present in the market just before the opening. Our results provide useful guidance for the assessment of the influence of HFTs’ quotes on price quality, an important issue for market regulators and policy makers.     

Determining factors and impacts of the intention to adopt mobile banking app in Cameroon: Case of SARA by afriland First Bank

This study aims to know what are the factors determining the adoption of M-Banking app among customers in Cameroon. In other words, what are the factors that influence users in their decisions to adopt and use a system or technology such as the MBanking app, and indirectly, what is the impact of this use on both the customers and financial inclusion? The research model developed relying on a combination of Technology Acceptance Model (TAM ), Unified Theory of Acceptance and Use of Technology ( UTAUT2 ), Information System Success Model ( ISSM ), and Protection Motivation Theory ( PMT ) and other constructs; it was then tested with a sample of 223 users of the “ SARA” M-Banking app of the financial institution called “ Afriland First Bank” . Findings revealed that: (1) utilitarian expectation, hedonic motivation, and status gain, habit, and perceived privacy concern have a significant influence on the intention to adopt M-Banking apps; and (2) the exploitative/explorative use of this technology has an impact on user’s loyalty and satisfaction but also contributes strongly to fostering financial inclusion in Cameroon. Also, the Multi-group analysis was performed on the sample using 2 gender-based groups (males, n=121; females, n=102).     

The Effect of Friendly Persuasion and Gender on Tax Comliance Behavior

Friendly persuasion, in contrast to deterrent measures like tax audits and penalties on underreported taxes, is a positive and possibly a cost effective method of increasing taxpayer compliance. However, prior studies have failed to show that friendly persuasion has a significant impact on compliance (Blumenthal et al., 2001; McGraw and Scholz, 1991). In our study, in contrast to prior studies, we examine the impact of generating and reading reasons supporting compliance as friendly persuasion on individuals' income reporting behavior as well as control for gender effects. Specifically, we predict an interaction effect between friendly persuasion and gender on compliance behavior. We carried out a 2 (friendly persuasion and control) × 2 (men and women) full factorial experiment, where participants earned $30 by completing two questionnaires. Participants in the friendly persuasion group were required first to generate and second to read a list of reasons why they should comply fully. Afterwards, participants in both groups were asked to report the income they earned and pay tax on the reported income. The results show a significant main effect for gender as well as a significant interaction effect between gender and friendly persuasion on income reported. Women in the friendly persuasion group reported significantly higher income compared to men in that group. Other comparisons were not significant. Policy implications for increasing taxpayers' ethics and compliance are highlighted.

目的：探讨患者发生药品不良反应（ADR）的特点,加强ADR监测,促进临床合理用药。方法收集惠州市中医医院2014年通过广东省药品不良反应管理平台报告ADR监测网的106例ADR报告,对患者的年龄、性别、给药途径、药物联用情况、ADR累及器官或系统及临床表现等方面进行分类统计和分析。结果106例ADR报告中,患者年龄最小3岁,最大85岁,其中以大于50岁的患者居多,共57例,占53.7%;发生ADR患者的主要给药途径为静脉滴注;涉及药品共9类,以使用抗感染药品出现ADR最多见,中药制剂次之;两药联用最多见,占51.9%;主要以皮肤及其附件损伤为主,共27例,占25.5%;消化系统、神经系统次之;治疗后56例患者治愈,50例好转。结论由于ADR的发生与多种因素相关,存在一定的不可预见性,因此临床需提高对ADR的重视程度,加强对ADR的监测与报告,减少ADR的发生,保障临床用药安全。     

Are voters rational?

We test whether a voter's decision to cast a vote depends on its probability of affecting the election outcome. Using exogenous variation arising at population cutoffs determining council sizes in Finnish municipal elections, we show that larger council size increases both pivotal probabilities and turnout. These effects are statistically significant, fairly large and robust. Finally, we use a novel instrumental variables design to show that the jumps in the pivotal probabilities are the likely candidate for explaining the increase in turnout, rather than the other observed simultaneous jumps at the council size cutoffs. Moreover, our results indicate that turnout responds only to within-party pivotal probabilities, perhaps because they are more salient to the voters than the between-party ones.     

Should Cookie Monster adopt a healthy lifestyle or continue to indulge? Insights into brand icons

Developing a brand icon has been a way for marketers to humanize and forge relationships with consumers. Icon development takes time. During this time, marketers have to face how much they stay true and consistent with their icons and how much they allow their icons to adapt to cultural changes in the marketplace. Little is known about how consumers respond to changing icons, and even less is known about whether there may be certain consumer groups that are more or less receptive to such changes. Four experiments and qualitative interviews were undertaken to gain insights into these issues. People who have a low need to belong were most impacted by changes in the icon, with effects most evident among consumers with a fearful attachment style. Feelings of rejection were found to amplify these effects. These findings have implications both for theory and practice.     

Portfolio constraints,differences in beliefs and bubbles

I propose an arbitrage-based theory of bubbles in economies with general portfolio constraints and differences in beliefs. I find that, in general, bubbles cannot exist unless the constraints restrict the demand for credit sufficiently to induce low interest rates. Speculation due to heterogeneous beliefs does not cause bubbles. Ruling out bubbles under asymmetric information requires stronger assumptions: the presence of some uninformed agents and mild portfolio restrictions (debt or borrowing constraints), or alternatively, the existence of some impatient and fully informed agents.     

Bubbles,banks and financial stability

The macroeconomic impact of rational bubbles in a limited commitment economy crucially depends on whether banks or ordinary savers hold the bubble. Banks hold the bubble asset when their leverage is high, when long-term real interest rates are low or when lax supervision allows them to enjoy high deposit insurance subsidies. When banks are the bubble-holders, this amplifies the output boom by reducing loan–deposit rate spreads while the bubble survives but also deepens the recession when the bubble bursts. In contrast, the real impact of bubbles held by ordinary savers is more muted.
