Outperformance portfolio optimization via the equivalence of pure and randomized hypothesis testing

We study the portfolio optimization problem of maximizing the outperformance probability over a random benchmark through dynamic trading with a fixed initial capital. Under a general incomplete market framework, this stochastic control problem can be formulated as a composite pure hypothesis testing problem. We analyze the connection between this pure testing problem and its randomized counterpart, and from the latter we derive a dual representation for the maximal outperformance probability. Moreover, in a complete market setting, we provide a closed-form solution to the problem of beating a leveraged exchange traded fund. For a general benchmark under an incomplete stochastic factor model, we provide the Hamilton–Jacobi–Bellman PDE characterization for the maximal outperformance probability.     

The Channel That Offers the Lowest Online Room Rates: A Case Study of Hotels in Hong Kong

Online distribution channels increasingly serve as platforms hotels can use to offer competitive room rates to attract price-sensitive customers and maximize yield. Capturing the lowest and highest daily room rates over a 360-day period from five of the most popular online travel agencies, and two batches of data showing the lowest room rates over 28 days from a last-minute bookings website, this study compares the lowest prices offered. The results indicate that no single online channel outperforms the others in any of the hotel star-rating categories, and that the last-minute reservation service provides the lowest hotel room rate across different star ratings.     

Ethics Education in the Australian Accounting Curriculum: A Longitudinal Study Examining Barriers and Enablers

Abstract

The increasing significance of ethics in the accounting profession is evidenced by the seminal events that witnessed the collapse of major corporations (e.g. Enron and WorldCom); regulatory interventions (e.g. Sarbanes-Oxley Act in the USA and the CLERP 9 Act in Australia); and calls for increased ethics interventions in the accounting curriculum. This project has two objectives: to investigate the nature of ethics education in the Australian accounting curriculum and how it has changed from 2000 to 2012; and to analyse the barriers to enhancing ethics education by soliciting the opinions of Heads of Departments/Schools of Australian universities. Compared with early empirical evidence, universities responded to the call for ethics education with increased levels of ethics intervention, but had failed to enhance the extent of ethics education coverage in the intervening period in which the data were collected. The lack of qualified staff and research opportunities represent major obstacles to the enhancement of ethics education.     

In the Shadow of the United States: The International Transmission Effect of Asset Returns

We examine how fluctuations in financial and housing markets in the United States affect asset returns and GDP in Hong Kong. In contrast to studies using linear specifications, which find that the United States and Hong Kong are virtually delinked in terms of the asset markets, our regime‐switching models indicate that an unexpected change in US stock returns, followed by the TED spread, has the most significant effect on Hong Kong asset returns and GDP, typically in a regime of high return and low volatility. For in‐sample one‐step‐ahead forecasting, the US term spread is the best predictor.     

Can Anchoring and Loss Aversion Explain the Predictability of Housing Prices?

We offer an explanation of why changes in house price are predictable. We consider a housing market with loss‐averse sellers and anchoring buyers in a dynamic setting. We show that when both cognitive biases are present, changes in house prices are predicted by price dispersion and trade volume. Using a sample of housing transactions in Hong Kong from 1992 to 2006, we find that price dispersion and transaction volume are, indeed, powerful predictors of housing return. For both in and out of sample, the two variables predict as well as conventional predictors such as the real interest rate and real stock return.     

Public housing units vs. housing vouchers: Accessibility,local public goods,and welfare

We develop a general equilibrium model of residential choice and study the effects of two housing aid policies, public housing units and housing vouchers. Land is differentiated by both residential accessibility and local public goods, and the provision levels of local public goods are determined by property tax revenues and neighborhood compositions. Households differ in their incomes and preferences for local public goods. Housing aid policies are financed by general income taxes. We discuss how the location of public housing units is a fundamental policy variable, in addition to the numbers and sizes of units, and argue that vouchers not only cause less distortion for social welfare compared to public housing, but may also improve overall welfare.     

The role of relational orientation as measured by face and renqing in innovative behavior in China: An indigenous analysis

Following an indigenous approach, the relationship of the relational orientation of Chinese employees with their innovative behavior is evaluated in China with a cross-level design. Based on relevant research and theorizing, relational orientation is tapped by two core elements, face and renqing (compassion for others). As expected, relational orientation is positively related to fear of failure, but negatively related to innovative behavior. The positive relationship between relational orientation and fear of failure, and the negative relationship between fear of failure and innovative behavior, are weaker when innovative climate is high. Theoretical and applied implications of the findings are discussed.     

An examination of the influence of guanxi and xinyong (utilization of personal trust) on negotiation outcome in China: An old friend approach

Managers of multi-national enterprises (MNEs) are at a disadvantage in negotiating outcomes with their Chinese counterparts when compared to local competitors. The reasons include: local competitors are more flexible in handling business terms and conditions; local Chinese managers prefer to negotiate with their old friends or insiders in the same guanxi network; and MNE managers perceive that cultural practices such as gift-giving and guanxi are problematic. This study advances our understanding of negotiation by using a model developed for the reference of MNEs to establish an “old friend” relational status with their local Chinese counterparts. This approach emphasizes cultural adaptation for MNE managers to achieve satisfying negotiation outcomes in China.The study reveals the following unique issues: 1) in addition to their problem-solving attitude, MNE managers should practice mianzi and gift-giving to build renqing with their Chinese counterparts at a new friend stage; 2) the reciprocity dynamics of renqing should enable these managers to accumulate ganqing and to become old friends of their Chinese counterparts; 3) the establishment of ganqing between MNE managers and their Chinese counterparts should enable the development of xinyong between the two exchange parties; and 4) desirable negotiation outcomes can be built on xinyong.
