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.

香港旅遊業發展有何新方
香港旅遊業發展有何新方
港人北上,反向消費,已經成為新冠疫情后香港與大灣區旅遊消費的常態。根據旅遊發展局公布數據,2023年訪港內地旅客共2676萬人次,遠低於疫情前2019年的4377萬人次以及2018年的5104萬人次。相比之下,內地旅遊則大幅發展。2023年北上香港居民累計達5300萬人次,恰好為訪港內地旅客的兩倍,其中超過4000萬經深港各個口岸出境。

北上消費 挖空經濟?
剛剛過去的五一假期,在內地被稱為吃喝玩樂爆棚的消費黃金周,算是給略顯疲態的中國經濟帶來一股暖流。雖然香港部分商家也受益於內地黃金周的溢出效應,但其作用就像這幾天市民議論紛紛的五一煙火表演,站在有利位置倒也頗為可觀,但畢竟不像射向高空的煙花那般絢爛,稍微遠離樓台就只能空對月。

百分之二通脹目標與美國通脹
這兩天又是美國聯儲局議息的日子。從2022年3月到2023年7月的短短16個月內,聯儲局持續提高政策利率以遏抑40多年未有的高通脹,累計加息5.25厘。至去年11月,以消費物價指數(CPI)計算的年通脹率,已由2022年6月的9.06%高峰下降至3.14%。若以聯儲局關注的個人消費支出物價指數(PCE)計算,去年10月至12月的按月增幅均差不多為零。市場樂見遏抑通脹見成效,預期2024年將進入減息周期,甚至有估計認為全年會減息6次。
