Optimal reinsurance arrangements in the presence of two reinsurers

In this paper, we investigate the optimal form of reinsurance from the perspective of an insurer when he decides to cede part of the loss to two reinsurers, where the first reinsurer calculates the premium by expected value principle while the premium principle adopted by the second reinsurer satisfies three axioms: distribution invariance, risk loading, and preserving stop-loss order. In order to exclude the moral hazard, a typical reinsurance treaty assumes that both the insurer and reinsurers are obligated to pay more for the larger loss. Under the criterion of minimizing value at risk (VaR) or conditional value at risk (CVaR) of the insurer's total risk exposure, we show that an optimal reinsurance policy is to cede two adjacent layers, where the upper layer is distributed to the first reinsurer. To further illustrate the applicability of our results, we derive explicitly the optimal layer reinsurance by assuming a generalized Wang's premium principle to the second reinsurer.

Do regulations limiting management influence over auditors improve audit quality? Evidence from China

We use data from China to examine whether regulations that limit management influence over auditors improve audit quality. China’s State-owned Assets Supervision and Administration Commission of the State Council (SASAC) issued two rules in 2004 aimed at improving audit quality for state-owned enterprises ultimately controlled by the central government (CSOEs). These rules limit management influence over auditors by mandating that SASAC assign auditors for CSOEs and by requiring management to retain auditors for at least 2 years and at most 5 years. Since these rules apply only to CSOEs, we use a difference-in-difference design to study the impact of these regulations on audit quality. We find that audit quality for CSOEs relative to other companies improves after the enactment of these rules. Our results are robust to a battery of sensitivity analyses. Our findings suggest that limiting management influence over auditors helps improve audit quality.

LINKAGES: DO FOREIGN FIRMS BUY LOCALLY IN TAIWAN?*

Linkages are important potential impacts of DFI upon host economies. Since these potentialities are not necessarily realized, we must separate the potential (ex ante) and actual (ex post) results of these effects. Empirical data for Taiwan in the 1970s show that DFI may tend to concentrate in industries with strong backward linkages. More significantly, DFI located in EPZs or controlled by non-Chinese investors had a clear tendency to import more and, hence, to form enclaves. However, this group of firms greatly improved its procurement policies over time. Thus, while discernible in the short run, the enclavistic phenomenon linked to DFI becomes insignificant in the long run, as shown by Taiwan's experience. Needless to say, the gradual rise of the local content rate of foreign firms is in line with successful development of the local material industries in Taiwan in the 1970s (Schive, forthcoming). In addition to the time factor, several firms specific factors such as foreign ownership structure, export propensity, status as a producer of either final or intermediate goods, status as a “neighboring” or “distant” investor, and the scale of operation all have a bearing on foreign firms' local purchasing behavior. To determine whether these findings pertain to Taiwan only, further country comparative studies are needed.     

国家视角下的目的地形象模型——基于来华国际游客的实证研究

国家形象和目的地形象因其对消费者行为和决策的重要影响,分别发展成为国际商务领域和旅游营销领域的重要概念和研究热点,虽然两者具有十分密切的内在联系,但学界对它们的研究却相对独立,缺少交叉研究.该研究在对两个领域的文献和理论模型进行整理后,将目的地形象放置到国家尺度下重新审视,试图揭示一个国家的综合国家形象与其作为旅游目的地的形象之间的互动机制,并尝试引入“熟悉度”等概念建立整合模型.最后以中国大陆为案例地,以来华国际游客为调查对象,通过结构方程模型进行实证检验和修正.结论指出:(1)熟悉度对目的地形象有正向影响;(2)国家形象与目的地形象之间具有双向且正向的影响;(3)国家形象通过目的地形象对游客的忠诚度产生间接影响.

Incentives to move up: Effects of pay gaps between levels on employee performance

Employees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.
