为客户服务中心计算客户耐性的危机率
为客户服务中心计算客户耐性的危机率
以时间为单位量度客户的耐性并计算危机率,已成为运营管理中重要的一环。这项技术能帮助企业优化客户服务中心的运作,如人手分配及编更事宜等等。当客户申请服务时,他们的耐性将会随时间推移产生改变。现行的数据收集系统有时候无法观察到客户服务中心提供服务的确切时间,故此我们开发了一个TunT(Transform-unTransform)的估计程式,把这个复杂的难题简化为回归分析的问题。我们为客户服务中心不同的服务时间进行分类,并使用均值匹配转换,对相关的数据进行转换,从而使我们能简单地表现出异方差-变异数函数。然后我们把非参数回归分析的技术应用在转换后的数据上。最后,我们会对估计出来的回归函数进行转换,计算出原始危机率。在我们的模拟计算中,我们利用客户服务中心的数据(实验组)与医疗保险计划中的数据(控制组)进行对比。研究证明,与现行方法相比,我们的模型能得出更准确的危机估计值,帮助企业优化人手安排。

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
特别提款权与全球经济复苏
新冠肺炎肆虐已逾一年。若以每日新增案例为指标,全球情况并没有好转。最近的80、90万宗,是2月时30、40万宗中的两倍多。一些国家如美国和英国,由于疫苗接种计划顺利展开,新增案例自年初起大幅减少。但在其他国家,情况并没有稳定下来,稍有不慎,便会出现如印度最近的惨况。现时全球都寄望于疫苗,但疫苗的供应有先后之分。高收入国家已购买的剂量,是成年人口的两倍半,但中收入和低收入国家购买的剂量,只及成年人口的1/3。

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.
