Learning from a black box
Learning from a black box
We introduce a learning model in which the decision maker does not know how recommendations are generated, called the contraction rule. We present behavioral postulates that characterize it. The contraction rule can be uniquely identified and reveals how the decision maker interprets and how much she trusts the recommendation. In a dynamic stationary setting, we show that the contraction rule is not dominated by completely following recommendations and is incompatible with a property called compliance with balanced recommendations. Following this negative result, we demonstrate that the contraction rule may generate and reinforce recency bias and disagreement.

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:拉引营销活动对多元渠道企业进行有效营销的影响
整合分析:拉引营销活动对多元渠道企业进行有效营销的影响
是项研究为一个针对拉引营销活动如何影响多元渠道企业有效地推行营销活动的整合分析。高度灵活的拉引营销活动,目标是令多元分销渠道组合更具吸引力。作者透过整合以往的多元渠道分销文献,研究营销活动是否有效,与拉引营销活动及其分销渠道结构的配置,以及客户、竞争及产品类别的关系。是项分析结合研究样本的企业、数据和模型属性,发现当多元渠道企业在所有分销渠道中使用数码广告和价格促销时,营销活动更有效。跨渠道价格歧视并不会令营销活动更有效。此外,数码广告和价格促销是否配合多元化的渠道、渠道的丰富性、客户体验、市场竞争力和产品消费频率,也会对有效推行营销活动造成影响。

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.

香港通往成为国际Web3.0中心的路径
在过去十年,两大科技一直引领数字革命。首先是人工智能(AI),它已在全球得到了广泛应用,其次是备受争议的Web3.0,这是一种去中心化的区块链协议。本文将重点探讨Web3.0的发展,并进行深度解读。

数字平台有偏见 草根经济难创新
数字平台有偏见 草根经济难创新
数字平台通过降低消费者的搜索成本,有助于知名度不高的文化工作者找到知音,让在传统市场乏人问津的产品能以较低成本进入市场,令市场百花齐放。然而,在“流量为王”的时代,平台运营日趋偏颇,尤其是在中国的数字文艺娱乐市场,平台的推送和操纵能决定一部作品的命运,甚至窒碍产业创新。
香港经济三大挑战与四条出路
香港经济三大挑战与四条出路
香港经济自二战后尽管经历多次起伏,其国际金融及贸易中心地位,依然在世界经济舞台上历久不衰。 然而,面对近年全球经济增长放缓、区域竞争激烈及地缘政治局势恶化,香港作为高度外向型的自由经济体,我们不能因为过去均能化危为机便心存侥幸。 时移世易,香港现时面对人口老化等诸多内忧,加上外部挑战,未必如昔日般「耐寒」。

当AI敲门 音乐产业命运何去何从?
今天当我们戴上耳机聆听音乐时,会否意识到超过30%的音乐已经是由AI生成的?从去年一首AI生成歌曲Heart on My Sleeve在Spotify上一举获得逾2000万的点击,到今年年初,最大唱片公司环球唱片(Universal Music)因为AI音乐泛滥,而把旗下所有音乐从最大手机短视频平台TikTok上撤销,再到今年年中环球唱片和TikTok达成协议,后者同意在所有AI音乐视频上加上“AI音乐”的标签,AI技术对音乐产业的影响来势汹汹。

港大经管学院副院长(对外事务)邓希炜教授表示,由于地缘政治因素,加上内地本土市场过度竞争,不少当地龙头企业希望「出海」开拓市场。他举例,近期来港挂牌的美的集团(00300)及顺丰(06936)在内地上市多年,择此时机在港挂牌,希望作全球部署。他直言,若只在上海或北京设置总部,内地资本管制下,资金较难投资外地,「几十亿资金难以到马来西亚或越南」;以香港作为地区总部,就可集资及投资外地市场,扩展商业版图。
