Understanding road traffic risks from the street hawker’s perspective

This study explored street hawkers’ lived experiences and risks in traffic using the phenomenological case study design. Data from 24 hawkers at three hawking spots and field observations form the basis of our study. A stratified purposeful sampling scheme was employed to ensure a balance of gender and age. Thematic data analytic strategy was employed in the data analysis. We found that participants’ traffic incidents were mainly self-induced, attributable to their negligence on the road, indiscriminate road crossing and car-following behaviour. Our results suggest a perceived relationship between socio-demographic characteristics and personal traffic accident encounters. Also, we noted that the ability to manage traffic risk seem to influence hawkers’ traffic risk perceptions, with gender and age as possible mediators. As this study is exploratory, we recommend further scientific enquiry to explain these issues and to provide the basis for appropriate interventions to manage the road safety implications of this activity.     

Online persuasion of review emotional intensity: A text mining analysis of restaurant reviews

Consumer-generated restaurant reviews are important sources in consumers’ purchase decisions. The purpose of this study is to explore the impact of emotional intensity on perceived review usefulness as well as the moderating effects of review length and reviewer expertise. Data from 600,686 reviews of 300 popular restaurants in the US were obtained from Yelp. Using a text mining approach and econometric analysis, empirical results show that (1) positive emotional intensity has a negative impact on perceived review usefulness, whereas negative emotional intensity has a positive impact on perceived review usefulness; (2) among the two most prevalent discrete negative emotions in online reviews (i.e., anger and anxiety), reviews expressing anger are more useful than those expressing anxiety; and (3) review length and reviewer expertise can moderate the effect of emotional intensity on perceived review usefulness.     

What drives customers’ post-purchase price search intention in the context of online price matching guarantees

Using a research model based on customer value theory, this study investigates the determinants of customer post-purchase price comparison searches in the context of online price-matching guarantees (PMG). Data collected from 222 eligible respondents are tested against the proposed research model using partial least squares structural equation modeling (PLS-SEM). The results indicate two PMG characteristics, refund length and refund scope, influence utilitarian benefit (i.e., refund depth) and hedonic benefit (i.e., playfulness). These two benefits subsequently contribute to customer perceived value, which leads to price search intentions. This study pioneers the exploration of online PMGs and the determinants of customer post-purchase price search intentions. Several important theoretical and practical implications can be drawn from the findings to guide online retailers’ PMG strategies.     

资本弱化税制的比较分析及对我国的启示

本文对正常交易法和固定比例法两种规制资本弱化税制进行了比较研究后认为,正常交易法由于依据个案进行判断,因而精确和公正,但却以牺牲法律效率为前提;固定比例法虽然具有任意性和不精确性的特点,但其提高了企业的预见性,节约了税务机关的行政成本和纳税人的奉行成本,具有法律的效率优势。而后,分析了构造固定比例法四个要素。在此基础上,对我国目前资本弱化税制现状进行了分析,并提出了完善的方向。

Impact of Sales Call Adaptiveness and Customer Willingness on Sales Call Length: A Cross-Country Study of India,China, Korea,and Philippines

ABSTRACT

In this empirical study across four countries (India, China, Korea, and Philippines), we examine the impact of sales call adaptiveness and customer willingness on sales call length (duration) of salespersons in these four countries. Sales call length as well as sales call quality—although important constructs in sales—are still underresearched in the domain of sales management. Our study in these four emerging markets sheds new light on enhancing sales force effectiveness. Using survey data from 847 salespersons in four countries, we analyze using multivariate analysis, and our results suggest that sales force effectiveness can be enhanced by giving them the autonomy to decide the sales call length based on the prospect quality. We also demonstrate that salespeople indulging in sales-oriented behaviors may be detrimental to the long-term relationship with customers. Emphasis on relational sales approaches would reduce sales practices such as pitching products or services to unwilling customers. Our study also highlights the interactive role of customer willingness and sales adaptiveness. We found several inter-country differences across sales practices in four countries, which have several meaningful managerial implications.     

Relationship Quality and Performance Outcomes: Achieving a Sustainable Competitive Advantage

As firms strive to develop a sustainable competitive advantage, the relationships formed among supply chain parties become a critical consideration. Firms seek to establish relationships that can provide the desired level of performance and competitiveness. Relationship quality provides a global measure of buyer–supplier relationships and can be used to assess the types of relationships a firm has within its supply chain. This research examines the impact of relationship quality on supply chain operational performance and satisfaction with strategic performance while considering both buyer and supplier perspectives and collaborative and arm’s length types of relationships.

The effects of eWOM characteristics on consumer ratings: evidence from TripAdvisor.com

Abstract

Given the rise of online review communities, the management of consumer ratings has gained much attention in the recent years. In this study, we use data from Tripadvisor.com and examine the number of stars that a review receives. Specifically, we address how a star rating is determined by the components in the focal review as well as the preceding reviews of other consumers. Our qualitative and quantitative analyses provide interesting findings as follows. A star rating has a positive relationship with the focal review’s valence. That is, the more positive a review is, the greater number of stars a review receives. The reviews of other consumers also play a role in determining a star rating of the focal review suggesting social influence among consumers. Interestingly, a review with lengthy content leads to a lower star rating only when using smartphones. We conclude with theoretical and managerial implications.     

Probability of multiple crossings and pricing of double barrier options

This paper derives pricing formulas of standard double barrier option, generalized window double barrier option and chained option. Our method is based on probabilitic approach. We derive the probability of multiple crossings of curved barriers for Brownian motion with drift, by repeatedly applying the Girsanov theorem and the reflection principle. The price of a standard double barrier option is presented as an infinite sum that converges very rapidly. Although the price formula of standard double barrier option is the same with Kunitomo and Ikeda (1992), our method gives an intuitive interpretation for each term in the infinite series. From the intuitive interpretation we present the way how to approximate the infinite sum in the pricing formula and an error bound for the given approximation. Guillaume (2003) and Jun and Ku (2013) assumed that barriers are constant to price barrier options. We extend constant barriers of window double barrier option and chained option to curved barriers. By employing multiple crossing probabilities and previous skills we derive closed formula for prices of 16 types of the generalized chained option. Based on our analytic formulas we compute Greeks of chained options directly.
