為客戶服務中心計算客戶耐性的危機率
為客戶服務中心計算客戶耐性的危機率
以時間為單位量度客戶的耐性並計算危機率,已成為運營管理中重要的一環。這項技術能幫助企業優化客戶服務中心的運作,如人手分配及編更事宜等等。當客戶申請服務時,他們的耐性將會隨時間推移產生改變。現行的數據收集系統有時候無法觀察到客戶服務中心提供服務的確切時間,故此我們開發了一個TunT(Transform-unTransform)的估計程式,把這個複雜的難題簡化為迴歸分析的問題。我們為客戶服務中心不同的服務時間進行分類,並使用均值匹配轉換,對相關的數據進行轉換,從而使我們能簡單地表現出異方差-變異數函數。然後我們把非參數迴歸分析的技術應用在轉換後的數據上。最後,我們會對估計出來的迴歸函數進行轉換,計算出原始危機率。在我們的模擬計算中,我們利用客戶服務中心的數據(實驗組)與醫療保險計劃中的數據(控制組)進行對比。研究證明,與現行方法相比,我們的模型能得出更準確的危機估計值,幫助企業優化人手安排。

Disguised Corruption: Evidence from Consumer Credit in China
Disguised Corruption: Evidence from Consumer Credit in China
Using a comprehensive sample of credit card data from a leading Chinese bank, we show that government bureaucrats receive 16% higher credit lines than non-bureaucrats with similar income and demographics, but their accounts experience a significantly higher likelihood of delinquency and debt forgiveness. Regions associated with greater credit provision to bureaucrats open more branches and receive more deposits from the local government. After staggered corruption crackdowns of provincial-level political officials, the new credit cards originated to bureaucrats in exposed regions do not enjoy a credit line premium, and bureaucrats’ delinquency and reinstatement rates are similar to those of non-bureaucrats.

Distribution Channel Choice and Divisional Conflict in Remanufacturing Operations
Distribution Channel Choice and Divisional Conflict in Remanufacturing Operations
We consider a firm consisting of two divisions, one responsible for designing and manufacturing new products and the other responsible for remanufacturing operations. The firm will sell these new and remanufactured products either directly to the consumer (direct selling) or through an independent retailer (indirect selling). Our study demonstrates that a firm’s organizational structure can affect its marketing decisions. Specifically, a decentralized firm with separate manufacturing and remanufacturing divisions can benefit from indirect selling with higher firm profit, supply chain profit, and total consumer demand than direct selling. Moreover, this structure also induces a remanufacturable product design. In contrast, a centralized firm in which the manufacturing and remanufacturing divisions are consolidated is intuitively better off by choosing direct selling than indirect selling. Furthermore, we show that, surprisingly, when the focal firm sells through an independent retailer, a decentralized internal structure can result in higher supply chain profit than a centralized internal structure. We further investigate the case of dual dedicated channels and conclude that, while direct selling of remanufactured products and indirect selling of new products can better induce a remanufacturable product design and higher supply chain profit, it is not in the best interest of the firm in terms of total sales and firm profit.

How Breakthrough Innovation creates start-up success in competitive markets
How Breakthrough Innovation creates start-up success in competitive markets
The majority of fledgling businesses fly straight into the unforgiving rule of natural selection – only the fittest and strongest survive. In terms of start-ups, the rule is even more merciless. What can start-ups do to succeed in this brutal environment? Professor David Tse, Stelux Professor of Marketing and Director of the Contemporary Marketing Centre at the HKU Business School, believes Breakthrough Innovation (BI) is an effective strategy for success. Simply put, BI fosters strategies that help service new and under-served markets.
Everyone can win in business – or can they?
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.
In search of public service excellence
In search of public service excellence
Public services touch every aspect of the lives of people around the world. These millions of service users also have opinions, both good and bad, on the quality of the public services they access. But how often are they asked about these opinions? And do these opinions help create changes and improvements to the services?

Special drawing rights and global economic recovery
特別提款權與全球經濟復甦
新冠肺炎肆虐已逾一年。若以每日新增案例為指標,全球情況並沒有好轉。最近的80、90萬宗,是2月時30、40萬宗中的兩倍多。一些國家如美國和英國,由於疫苗接種計劃順利展開,新增案例自年初起大幅減少。但在其他國家,情況並沒有穩定下來,稍有不慎,便會出現如印度最近的慘況。現時全球都寄望於疫苗,但疫苗的供應有先後之分。高收入國家已購買的劑量,是成年人口的兩倍半,但中收入和低收入國家購買的劑量,只及成年人口的1/3。

人口老化 危中有機
本地人口結構正經歷人口老化的轉變,特區政府估計20年後,每3個香港人中,約有1人是65歲或以上的長者,而長者人口增長的一個特點就是,80歲及以上的增幅在未來40年間尤為顯著。2021年80歲及以上人口約為40萬(5.3%),到2040年會倍增至接近99萬(12.2%),2060年更將跳升到125萬(16.3%)

Iron ore is saving Australia’s trade with China. How long can it last?
Wine and wheat. Lobsters and logs. Beef and barley. If Australia exports it, China has likely put up barriers to entry over the past year, as diplomatic relations between the two countries rapidly deteriorated. Now, one commodity is almost single-handedly keeping the trade relationship afloat: iron ore.
