Randomized observation periods for the compound Poisson risk model: the discounted penalty function

In the framework of collective risk theory, we consider a compound Poisson risk model for the surplus process where the process (and hence ruin) can only be observed at random observation times. For Erlang(n) distributed inter-observation times, explicit expressions for the discounted penalty function at ruin are derived. The resulting model contains both the usual continuous-time and the discrete-time risk model as limiting cases, and can be used as an effective approximation scheme for the latter. Numerical examples are given that illustrate the effect of random observation times on various ruin-related quantities.     

Age misreporting: An empirical investigation using the New Zealand contingents in the Second Boer War

This is a first focused examination of age misreporting in military recruitment. We take advantage of an original dataset comprised of New Zealand military personnel records in the Second Boer War matched with birth historical records. First, we find that age misrepresentation is common: about one third of soldiers on our dataset misreport their ages. Second, we find that soldiers the estimated age-specific mean heights do not change significantly when we change from using reported ages to using true ages. Researchers can prioritise the investigation of true ages on those reporting to be 21 or younger.     

Attributes affecting the level of tourist satisfaction with and loyalty towards theatrical performance in China: Evidence from a qualitative study

This study seeks to explore attributes affecting the level of tourist satisfaction with and loyalty towards theatrical performance in China. Based on four focus group discussions with 31 participants, the study identifies 34 attributes that affect the level of tourist satisfaction with theatrical performance, and groups them into five categories: stage, performance, venue, service and tourist‐related attributes. The findings on tourist loyalty reveal that 21 of the 31 respondents would not watch the same theatrical performance alone in the future; however, they would recommend it to others. The study concludes with a discussion of the rich and insightful findings and their implications for tourism industry practitioners. Copyright © 2010 John Wiley & Sons, Ltd.     

Corporate social responsibility and provision of trade credit

In this article, we identify and examine three different views of corporate social responsibility (CSR) and the relationship between CSR and firms’ provision of trade credit. The trust view of CSR argues that CSR and trade credit provision are related positively, because CSR, as a trust-enhancing device, complements the incomplete contract nature of trade credit. The CSR literature shows that CSR firms tend to have higher cash holdings. With this in mind, the precautionary motive view of CSR suggests that cash holdings serve as a hedge against trade credit risk, while, on the other hand, the substitution view of CSR predicts that cash hoarding discourages the provision of trade credit. Using a dataset of 20,591 firm-year observations from 1991 to 2015, we find strong evidence that supports both the trust and substitution views of CSR but not the precautionary view of CSR.     

Budget-constrained optimal reinsurance design under coherent risk measures

ABSTRACT

Reinsurance is a versatile risk management strategy commonly employed by insurers to optimize their risk profile. In this paper, we study an optimal reinsurance design problem minimizing a general law-invariant coherent risk measure of the net risk exposure of a generic insurer, in conjunction with a general law-invariant comonotonic additive convex reinsurance premium principle and a premium budget constraint. Due to its intrinsic generality, this contract design problem encompasses a wide body of optimal reinsurance models commonly encountered in practice. A three-step solution scheme is presented. Firstly, the objective and constraint functions are exhibited in the so-called Kusuoka's integral representations. Secondly, the mini-max theorem for infinite dimensional spaces is applied to interchange the infimum on the space of indemnities and the supremum on the space of probability measures. Thirdly, the recently developed Neyman–Pearson methodology due to Lo (2017a) is adopted to solve the resulting infimum problem. Analytic and transparent expressions for the optimal reinsurance policy are provided, followed by illustrative examples.     

On additivity of tail comonotonic risks

ABSTRACT

As perceived from daily experience together with numerous empirical studies, the multivariate risks demonstrate a strong coherence in the extremal dependence structure especially over the course of financial turmoil or industrial accidents and outbreaks. Under this motivating paradigm, we show the universal asymptotic additivity under upper tail comonotonicity, as the probability level approaching to 1, for Value-at-Risk and Conditional Tail Expectation for a portfolio of fixed number of risks, in which each marginal risk could be any one having a finite endpoint or belonging to one of the three max domains of attraction. Our obtained results do not require the tail equivalence assumption as needed in the existing literature. This resolves a lasting problem in quantitative risk management and covers most distributions commonly encountered in practice.     

The Incidence of the Land Use Regulatory Tax

Land use regulation has been found to impose a substantial tax on housing within select U.S. metropolitan areas. In this article, we develop hypotheses regarding the incidence of this tax by income class and racial group within these areas. Parcel‐level data from Miami‐Dade County, Florida, are used to test our hypotheses. We find that, while the tax rises with a household's permanent income, this rise is less than proportional, making it a regressive tax. We also find, controlling for household permanent income, that the tax is a higher percentage of the price of homes located in black neighborhoods in comparison to those located in white or Hispanic neighborhoods.     

Subcultures in Greater China: A Comparison of Managerial Values in the People's Republic of China, Hong Kong, and Taiwan

Managerial values in the three regions that form Greater China — Hong Kong, Taiwan, and the People's Republic of China (PRC) — were compared. It is posited that in addition to Confucian philosophy, political and economic systems also have significant effects on the values of Chinese managers. Results show that despite the economic integration in Greater China, managerial values have yet to be unified. Managers in Hong Kong, Taiwan, and the PRC are convergent in collectivism and uncertainty avoidance. On the other hand, managers in the PRC demonstrated higher power distance and less concern about deadlines and plans than in managers Hong Kong and Taiwan. Materialism is also greater in the PRC and Hong Kong than in Taiwan.     

Covered interest arbitrage with transaction costs: An evidence from the Hong Kong foreign exchange market

This paper deals with the effects of transaction costs on the efficacy of covered and one-way interest arbitrage under the linked exchange rate system in the Hong Kong foreign exchange market. First, we examine the arbitrage opportunities in the swap market and in domestic and foreign securities markets. Second, we measure the profitability of covered interest arbitrage and one-way arbitrage. Empirical findings have shown that allowing for transaction costs, covered interest arbitrage seems to entail less unexploited opportunities for profit. However, there exists a great deal of unexploited profit opportunities in one-way arbitrage in the Hong Kong financial market.We are grateful to two anonymous referees and the editor for their helpful comments on an earlier version of this paper.     

Profitability of the CRISMA System: From World Indices to the Hong Kong Stock Market

Many studies show that the use of technical analysis can generate excess returns. We test the “CRISMA” technical trading rule introduced by [Pruitt and White J. Portfolio Managt. Spring, 1988, 55–58] on global equity indices and common stocks in Hong Kong. Out study shows that no excess returns could be found in indices except those in Asia. This validates the claims that the Asian stock markets are not as efficient as other stock markets and hence can be exploited by technical analysis. How does CRISMA perform on common stocks in Hong Kong? Generally speaking, CRISMA does not fair better than the buy and hold strategy. Further analysis reveals excess returns for stocks with very large turnover. This is consistent with other recent research on CRISMA conducted on US and UK stock markets. We also amend part of the original CRISMA rules to yield better performance: shrinking the moving average window sizes can increase both the number of trade signals and the excess returns. Therefore CRISMA can be made to work with some judicious choice of parameters, depending on the turnover.
