Growing user base in the early stage of sharing economy platforms: An integration of competitive repertoire and institutional legitimacy theories
Growing user base in the early stage of sharing economy platforms: An integration of competitive repertoire and institutional legitimacy theories
Sharing economy platforms are pressed to rapidly grow user bases at the early stage by aggressively targeting potential users through competitive actions. Due to the volatile nature of the sharing economy and its disruption to industry norms, these platforms encounter legitimacy challenges that impede user base growth. This paper integrates competitive repertoire and institutional legitimacy theories to develop a research model that explains early-stage user base development in the sharing economy. We posit that the early-stage user base is associated with structural characteristics of the competitive repertoire, whose effects are moderated by a platform's socio-political legitimation efforts that address stakeholders’ regulatory and normative concerns. Using a comprehensive sample of 4644 monthly observations of 129 sharing economy platforms in China, we find that the volume of two context-specific competitive actions, offering economic incentives and staging high-visibility events, along with competitive repertoire complexity, are positively related to the platform's early-stage user base. We also identify a significant negative relationship between repertoire differentiation and user base. Direct relationships are moderated by socio-political legitimation, however, such that legitimation weakens the positive impact of context-specific action volume but enhances those of repertoire complexity and differentiation. Managerial and practical implications are discussed in light of the findings.

Pushing Yourself Harder: The Effects of Mobile Touch Modes on Users’ Self-Regulation
Pushing Yourself Harder: The Effects of Mobile Touch Modes on Users’ Self-Regulation
Many mobile applications use push notifications and reminders to explicitly educate, remind, and motivate users to perform healthy behaviors. However, users do not always act according to these explicit digital interventions. Our study investigates whether users’ self-regulation can be implicitly facilitated with a proper mobile interaction design. Specifically, we investigate the impacts of two touch modes that are supported by force-based interaction technology, that is, pressing and tapping. Drawing on the theory of embodied cognition, which suggests that people automatically infer meanings from their bodily actions, we conjecture that pressing, compared with tapping, enhances self-regulation because the action of pressing on the touchscreen embodies resolute approach motivation toward goals. We test our hypotheses in three experiments. The first experiment investigates beverage choices on a mobile app; the second experiment examines goal setting on a fitness app; and the third experiment focuses on personal hygiene learning on a mobile education app. The results from the three experiments show that pressing actions can improve users’ self-regulation in selecting a healthier but less tasty beverage (Study 1), setting higher exercise goals and performing more physical exercise (Study 2), and reducing lapses in maintaining personal hygiene (Study 3). In addition, such effects were more salient among users with a higher level of health knowledge and a promotion-focused health orientation. This study contributes to healthcare IT research by showing that mobile interaction can be leveraged to nudge users toward enhanced self-regulation.

整合分析:拉引營銷活動對多元渠道企業進行有效營銷的影響
整合分析:拉引營銷活動對多元渠道企業進行有效營銷的影響
是項研究為一個針對拉引營銷活動如何影響多元渠道企業有效地推行營銷活動的整合分析。高度靈活的拉引營銷活動,目標是令多元分銷渠道組合更具吸引力。作者透過整合以往的多元渠道分銷文獻,研究營銷活動是否有效,與拉引營銷活動及其分銷渠道結構的配置,以及客戶、競爭及產品類別的關係。是項分析結合研究樣本的企業、數據和模型屬性,發現當多元渠道企業在所有分銷渠道中使用數碼廣告和價格促銷時,營銷活動更有效。跨渠道價格歧視並不會令營銷活動更有效。此外,數碼廣告和價格促銷是否配合多元化的渠道、渠道的豐富性、客戶體驗、市場競爭力和產品消費頻率,也會對有效推行營銷活動造成影響。

How to Recover from Work Stress, According to Science
How to Recover from Work Stress, According to Science
To combat stress and burnout, employers are increasingly offering benefits like virtual mental health support, spontaneous days or even weeks off, meeting-free days, and flexible work scheduling. Despite these efforts and the increasing number of employees buying into the importance of wellness, the effort is lost if you don’t actually recover. So, if you feel like you’re burning out, what works when it comes to recovering from stress? The authors discuss the “recovery paradox” — that when our bodies and minds need to recover and reset the most, we’re the least likely and able to do something about it — and present five research-backed strategies for recovering from stress at work.

Jian Zhang from the HKU Business School along with authors from the Shanghai Advanced Institute of Finance at Shanghai Jiao Tong University, INSEAD in Singapore and the PBC School of Finance at Tsinghua University, helped to advance understanding of this phenomenon in their recent paper, called Air Pollution, Behavioral Bias, and the Disposition Effect in China. The team studied how air pollution can affect mental health by intensifying a certain type of cognitive bias observed in financial markets.

現時經濟增長和土地供應量不足,帶動住屋需求和長遠樓價升勢,但由於中美的地緣政治、內地遊客消費模式改變,以及來自粵港澳大灣區競爭日益激烈,令寫字樓和零售店舖的空置率均錄得高水平。香港經濟發展應何去何從?

打造香港Web3.0中心任重道遠
從去年開始,在意識到傳統的金融市場發展會遇到一定瓶頸的情況下,香港便提出了發展Web3.0的戰略。Web3.0與Web2.0的主要區別之一在於使用者規模:目前Web3.0的用戶數量大約為1-2億,遠小於Web2. 0的用戶體量。 要實現Web3.0作為第三代互聯網的全面普及,使用者規模需起碼需要達到10億體量。但是要從1-2億增長到10億,中間還有很大的一個Gap。要解決這個Gap,一是傳統投資人能直接投Web3.0的資產;二是讓Web3.0上的投資人可以投資傳統資產;三是推動Web2.0與Web3.0的結合。

There Is a Time for Corporate Despots—but It Isn’t Forever
There Is a Time for Corporate Despots—but It Isn’t Forever
WSJ talked about the current trend of corporate dictatorships, where companies are run by founder-chief executives who hold on to special voting shares or run boards as their own personal fief. The article highlights a study by Prof. Roni Michaely of the University of Hong Kong, Hyunseob Kim of the Chicago Federal Reserve, and Doron Levit of University of Washington, which found that the benefits of a benign corporate dictatorship wane over time. The research, which examined 920 companies with both voting and non-voting shares, revealed an intriguing pattern. During the initial years following an IPO, companies with founder control tended to perform on par with their more democratically governed counterparts. However, after a decade or so, a significant premium emerged for shares with full voting rights. The article argues that granting full voting rights to all stakeholders is still the best form of governance for companies in the long run.
