中国在全球化中应举“新尊王攘夷”旗

30年的高速经济增长,使中国从引进式对外开放转向溢出式对外开放。驳斥国际上一些指责中国实行新殖民主义的论调,需要我们将殖民主义、民族国家和全球化问题联系起来进行深刻反思。世界正处在由资本经济向知识经济过渡的历史时期,中华文化的独特优势,在这一时期将大有作为。中国应适时举起新"尊王攘夷"大旗,回馈世界。

Right censoring in a discrete life model

Although there are many sophisticated models for estimation of failure rate based on censored data in continuous distributions, not much work has been done in the discrete case. We introduce a discrete model for life lengths and consider its properties. For this model, we derive the corresponding maximum likelihood estimators of the parameters under Type I and Type II right-censoring. Received May 2000     

Diversification strategies and failure rates in the Texas lodging industry: Franchised versus company-operated hotels

This research examines the relationship between geographic, brand, and segment diversification and hotel failure rates based on ownership structure, i.e. franchised and company-operated hotels, in the Texas lodging industry. Literature on diversification strategies is mainly based on financial measures of performance and offers mixed results; only few studies have assessed firm failure rates directly based on distinct diversification strategies at the establishment level. The performance outcomes are significantly heterogeneous not only based on the strategies, but also on the ownership structures, which are yet to be examined. Using data from the Texas Comptroller of Public Accounts from 2000 to 2018, a semi-parametric Cox proportional hazard model is estimated, and the findings reveal that failure rates are not significantly tied to particular types of diversification and ownership structures. This research provides insights on hotel diversification strategies and their relative dominance on hotel failure rates based on franchised and company-operated hotels.     

拉美和东亚国家(地区)在东亚金融危机后的经济恢复比较

1997～1998年的东亚金融危机给世界经济带来了巨大冲击,尤其是对东亚和拉美新兴市场国家和地区的经济造成了很大的破坏作用。本文试图对这两个区域危机后的经济恢复情况进行比较。首先,通过主成分分析法对16个国家和地区危机后6年的宏观经济指标进行了综合评估,实证结果表明,危机后的恢复程度存在着较大的差异和地域特征。接着本文对可能导致各国在危机后经济恢复差异的原因进行了实证研究,发现经济发展模式、储蓄率和外债负担等对原因的解释力较强。最后,本文对实证结果的政策含义进行了阐述。

Reliable product-service supply chains for repairable products

A mathematical model is developed for integrated flow planning in forward and after-sales supply chains of a company supplying repairable product-warranty packages to markets. Ignoring their interactions, these two supply chains are usually planned separately in literature. We consider demand- and supply-side variations in pre- and after-sales demands and qualified outflow of the SCs’ facilities. We show that to neutralize the impact of variations, orders should be amplified by moving from the downstream to the upstream of chains. Results of an example from the gear industry show what interdependencies exist between the company’s retail price, service levels, and warranty strategies.     

Contagion effect on bond portfolio risk measures in a hybrid credit risk model

This paper illustrates how modelling the contagion effect among assets of a given bond portfolio changes the risk perception associated to it. This empirical work is developed in a hybrid credit risk framework that incorporates recovery rate risk. Dependence structures among firms and between external shocks affecting firms together are considered. The presence of correlations among firm leverage ratios and the interrelation between default probabilities and recovery rates produces clusters of defaults with low recovery rates. This has a major impact on standard risk measures such as Value-at-Risk and conditional tail expectation. Consequently, an appropriate measurement of the contagion has a tremendous effect on the capital requirement of many financial institutions.     

What recovery options to offer for loyalty reward program members: Dollars vs. Miles?

Research shows that offering monetary compensation is effective in restoring customers’ equity perceptions following a service failure. However, little is known about loyalty reward program members’ responses to various types of recovery options. This study fills this important void by investigating two types of compensation: a discount coupon (in dollars) and bonus reward points (in miles) in the airline context. This study further investigates the boundary effect of controllability of a service failure. Our findings show that, when the flight delay is perceived as highly controllable by the airline company (i.e., scheduling error by flight crews, repatronage intention was higher in the 50-dollar discount vs. 2500 bonus miles condition. Conversely, repatronage intention did not differ between the two compensation options when the flight delay was perceived as uncontrollable i.e., inclement weather. Our findings help hospitality and tourism firms leverage service recovery initiatives for loyalty reward program members.
