The Copernican Revolution of Economics

被要求預測股票市場或宏觀經濟表現,是經濟學家經常遇到的「職業風險」。經濟學家對此往往無可奉告,皆因研究股市或宏觀經濟現象的學者為數甚少。所幸芝加哥大學經濟學教授利維特(Steve Levitt)在其暢銷名著《怪癖經濟學》(Freakonomics)中向大眾展示,經濟學家也會分析如警察數目和墮胎合法化對罪案率的影響、相撲手在賽事中作弊的誘因等,看似不屬於經濟學核心研究的問題。但有賴今年諾貝爾經濟學獎三位得獎者:加州大學伯克萊分校的卡德教授(David Card)、麻省理工學院的安格里斯特教授(Joshua Angrist)、史丹福大學的因本斯教授(Guido Imbens)的奠基工作和努力宣導,此等問題已經成為經濟學研究的主流之一。

疫市數碼轉型 HR責任擴大遇難題

新冠肺炎疫情驅動下,數碼時代變革加速。作為傳統行業的人力資源管理(HR),也正面臨着轉型升級的趨勢,無論是招聘渠道與面試方法、或是日常辦公以及培訓模式,均正逐步轉變。

Everyone can win in business – or can they?

‘Workers against bosses’ is a common theme, but mutual interest is more important in creating value, according to HKU Business School professors.

Hong Kong’s second curve

年屆88歲的查爾斯.漢迪(Charles Handy)是英國管理學大師,其著作《理解組織》(Understanding Organizations)更是組織研究的經典。近幾年,漢迪在中國內地聲望日隆,原因是他的一本小書《第二曲線》(The Second Curve)。

Negotiated Block Trade and Rebuilding of Trust

We investigate the impact of corporate governance on customers' trust using a dynamic model of experience‐goods firm. In the optimal equilibrium, customers' trust in the firm is linked to its behavior in the market for corporate control, so that the controlling shareholder has incentives to ensure high product quality while noncontrolling shareholders' interests are protected. Following a trust‐damaging event, turnover of the controlling share block restores customers' trust and enhances total shareholder value. Our analysis identifies an endogenous cost of corporate control, offers implications for the control premium, and provides a novel rationale for the separation of ownership and control.

Organisations’ dilemma amidst the spread of epidemics

管理學大師克里斯滕森(Clayton Christensen)今年1月不幸去世,他生前憑其所提出的「顛覆性創新」理論(Theory of Disruptive Innovation)聞名於世。2011年,其著作《創新者的窘境》(The Innovator's Dilemma)更被《經濟學人》(The Economist)評為史上六大商業名著之一;書中提出了一個極其重要的問題:成功高效的企業,往往不擅長自我革新,與時俱進。這些企業也許很早就知道了競爭者的新技術,但最初並不重視。新技術不成熟,吸引的顧客也有限。可問題是,當企業醒覺時,卻往往為時已晚。

Multilateral Interactions Improve Cooperation under Random Fluctuations

In an environment subject to random fluctuations, when does an increase in the breadth of activities in which individuals interact together help foster collaboration on each activity? We show that when players, on average, prefer to stick to a cooperative agreement rather than reneging by taking their privately optimal action, then such an agreement can be approximated as equilibrium play in a sufficiently broad relationship. This is in contrast to existing results showing that a cooperative agreement can be sustained only if players prefer to adhere to it in every state of the world. We consider applications to favor exchange, multimarket contact, and relational contracts.
