Detailed study of a moving average trading rule

We present a detailed study of the performance of a trading rule that uses moving averages of past returns to predict future returns on stock indexes. Our main goal is to link performance and the stochastic process of the traded asset. Our study reports short-, medium- and long-term effects by looking at the Sharpe ratio (SR). We calculate the Sharpe ratio of our trading rule as a function of the probability distribution function of the underlying traded asset and compare it with data. We show that if the performance is mainly due to presence of autocorrelation in the returns of the traded assets, the SR as a function of the portfolio formation period (look-back) is very different from performance due to the drift (average return). The SR shows that for look-back periods of a few months the investor is more likely to tap into autocorrelation. However, for look-back larger than few months, the drift of the asset becomes progressively more important. Finally, our empirical work reports a new long-term effect, namely oscillation of the SR and proposes a non-stationary model to account for such oscillations.     

The role of accountability in determining the relationship between financial reporting quality and the performance of public organizations: Evidence from Vietnam

Drawing on the new public management and agency theory, this study examines the mediating role of accountability in the relationship between financial-reporting quality and the performance of public organizations. The research model and hypotheses tested with a survey of 177 responses obtained from accountants and managers working in the public sector in Vietnam. Our analysis shows that accountability has a mediating role on the relationship between financial-reporting quality and performance, with significant implications for public organizations seeking to improve both their financial-reporting quality and their organizational performance with better designed systems of accountability.     

Improving the Economic Performance of Remanufacturing Systems through Flexible Design Strategies: A Case Study Based on Remanufacturing Laptop Computers for the Cambodian Market

Although numerous studies have highlighted the contributions of remanufacturing to sustainable development and the circular economy, the decision for a company to take up this strategy is riddled with uncertainties, especially when significant capital investment is involved. To improve the economic performance of a remanufacturing system in the face of uncertainties, we propose a methodological framework for flexible design of remanufacturing systems. Its application is demonstrated using a case study based on remanufacturing laptop computers for the Cambodian market. Through the case study, we show how one can explore the opportunity of setting up a remanufacturing system, study its economic feasibility and design flexible strategies to improve its economic performance in the face of uncertainties. More interestingly, we demonstrate how Monte Carlo simulation can be used to evaluate the effectiveness of different flexible design strategies in dealing with the uncertainties.

The Demand for Vices in Malaysia: An Ethnic Comparison Using Household Expenditure Data

A trivariate Tobit system is estimated to investigate the demand for vices (tobacco, alcohol, and gambling) in Malaysia. Estimation results, segmented by ethnicity, suggest that years of formal education, occupation type, and household head’s age negatively affect both the likelihood to spend and the overall amounts spent on tobacco by all Malaysians. Additionally, while higher income Malay households are more likely to spend and have higher tobacco expenditures, affluent Chinese and households of other races are more likely to spend and to spend more on smoking, drinking and gambling. Male-headed households of all races are more likely to spend and also spend more on smoking, drinking and gambling than female-led households.     

The effects of nutritional labels on obesity

This study examines the relationship between nutritional label use and obesity using switching regression. Results for treatment effect show that nutritional labels play a role in reducing obesity among users of nutritional labels, notably among women. The average body mass index (BMI) for men who read nutritional labels is 0.12 point lower than men who do not read them, while women who are users of nutritional labels have 1.49 points lower BMI than women who do not read labels. These findings imply that health education campaigns can employ nutritional labels as one of the instruments for reducing obesity.     

Financial investment behavior tendencies of air carriers

This study looks at the financial investment behavior of air carriers in Taiwan and the US stock markets. Application of the DHS model via behavioral finance theory indicates a tendency of becoming overly confident in Taiwan's domestic market. It is also known that Taiwanese investors react with excess optimism regardless of market conditions. Availability of private information before and after public announcements has little effect on investment behavior. Contrarily, US investors indicate a lower degree of overconfidence.
