Intertemporal volatility and price interactions between Australian and Japanese spot and futures stock index markets

Previous studies have examined causality within and between different spot and futures markets with a motivation to discover market comovements, price leadership effects, and, more recently, volatility spillovers across markets. However, the empirical framework within which this is accomplished tends not to analyze explicitly foreign spillover effects upon a spot–futures relationship, which may significantly alter the equilibrium between these markets. This will then have a direct impact upon the estimation of dynamic risk adjustments that occur from the interaction between these markets. This article develops a quadvariate simultaneous-equation EC-ARCH model with an emphasis on volatility spillovers as a better alternative methodology to evaluate these relationships from a different perspective. This model is applied to examine the interaction between the Australian and Japanese spot and futures stock index markets, which allows for an Australian or Japanese futures trader to analyze the impact of foreign cash and futures markets, as well as the local cash market, on the local futures market in a single coherent framework. This type of analysis is not possible using previous paradigms, because they allow the trader only to examine the impact of local cash and foreign futures markets in separate settings. © 1999 John Wiley & Sons, Inc.

Cost-effectiveness of omalizumab add-on to standard-of-care therapy in patients with uncontrolled severe allergic asthma in a Brazilian healthcare setting

Objective: Omalizumab add-on to standard-of-care therapy has proven to be efficacious in severe asthma patients for whom exacerbations cannot be controlled otherwise. Moreover, evidence from different healthcare settings suggests reduced healthcare resource utilization with omalizumab. Based on these findings, this study aimed to assess the cost-effectiveness of the addition of omalizumab to standard-of-care therapy in patients with uncontrolled severe allergic asthma in a Brazilian healthcare setting.

Methods: A previously published Markov model was adapted using Brazil-specific unit costs to compare the costs and outcomes of the addition of omalizumab to standard-of-care therapy vs standard-of-care therapy alone. Model inputs were largely based on the eXpeRience study. Costs and health outcomes were calculated for lifetime-years and were annually discounted at 5%. Both one-way and probabilistic sensitivity analyses were performed.

Results: An additional cost of R$280,400 for 5.20 additional quality-adjusted life-years was estimated with the addition of omalizumab to standard-of-care therapy, resulting in an incremental cost-effectiveness ratio of R$53,890. One-way sensitivity analysis indicated that discount rates, standard-of-care therapy exacerbation rates, and exacerbation-related mortality rates had the largest impact on incremental cost-effectiveness ratios.

Limitations: Assumptions of lifetime treatment adherence and rate of future exacerbations, independent of previous events, might affect the findings. The lack of Brazilian patients in the eXpeRience study may affect the findings, although sample size and baseline characteristics suggest that the modeled population closely resembles Brazilian severe allergic asthma patients.

Conclusion: Results indicate that omalizumab as an add-on therapy is more cost-effective than standard-of-care therapy alone for Brazilian patients with uncontrolled severe allergic asthma, based on the World Health Organization’s cost-effectiveness threshold of up to 3-times the gross domestic product.     

An analysis on perceived crowding level reported by domestic visitors of South Korean National Parks: a multilevel ordered logit approach

Perceived Crowding Level (PCL) is an indicator of the social carrying capacity of recreational sites such as National Parks. Using a sample of national-level visitor survey data across 21 National Parks in South Korea, this paper aims to apply a multilevel ordered logit model as a method in testing for statistical relationships between the PCL and the covariates, accounting for site- and individual-specific heterogeneity. The results hint that levels of perceived crowding in South Korean National Parks are related to factors such as the behaviour of other users and the quality of park facilities such as comfort in accommodation. The measured level of heterogeneity can provide useful information about the level (nation-wide or park-specific) of intervention policies and management strategies.     

Real Earnings Management,Liquidity Risk and REITs SEO Dynamics

We analyze how REITs managers use real earnin gs management to address issues of liquidity risk and increased cost of capital they face during seasoned equity offerings. We show that REITs managers engage in real earnings management instead of accrual earnings management to attract more uninformed trading in order to provide the liquidity service at a lower cost during seasoned equity offerings. We find REITs with higher liquidity risk are more likely to manipulate earnings prior to equity offerings and uninformed trading is higher following real earnings management. Firms set the offer price at a smaller discount after engaging in real earnings management and stock returns decline in the long run. The findings are consistent with real option and liquidity risk explanations for equity offerings.     

Demystifying the Management Structure Puzzle: an Empirical Investigation into the Drivers of REIT Internalization

Real estate investment trusts (REITs) have grown to become an important financial product in Asia, which today stands as the second largest REIT market in the world. Although existing literature has shown that externally managed REITs have underperformed their internally managed counterparts, the Asian REITs market has a strong preference for the external management model. This paper investigates the factors that drive REITs to internalize or deter them from internalizing their manager by studying the characteristics of 26 internalization subjects in Australia at their point of internalization. We compare their financial, corporate governance and portfolio characteristics to a control group. We find the MBR, the parent of the REIT manager, the asset size, and the geographic diversity of assets to be significant determinants of the probability of these REITs internalizing their manager. The low growth prospect faced by large Australian REITs that had a domestic investment focus motivates them to internalize their manager.     

Dominant stakeholders,activity and accountability discharge in the CSO sector

Civil society organisations (CSOs) comprise a diverse range of associations, including non‐governmental organisations (NGOs), community groups, political parties and social networks. Nevertheless, despite heterogeneity, regulators, funders and donors often treat CSOs as homogeneous when demanding accountability. This paper highlights differences in to whom CSOs across different categories (or types) perceive themselves to be accountable, what for and the different practices they undertake to discharge accountability. It calls for stakeholders to acknowledge diversity in accountability across different CSO types. This survey‐based research finds CSOs weight upwards and downwards stakeholders equally, and undertake voluminous reporting. They would benefit from negotiating multiple‐use mechanisms, especially with dominant stakeholders. In combining stakeholder and accountability theory, the research highlights specific CSO types needing further study.     

Matching rules

Institutions often utilize matching rules to achieve cooperative outcomes. However, the equilibrium induced by a matching rule may not be socially optimal. After presenting the case in which matching rules yield privately and socially optimal levels of cooperation, this article identifies the conditions which generate inefficient cooperation. Matching rules undershoot (i.e. parties cooperate less than is socially optimal) in one group of cases. In a second, more puzzling case, matching rules overshoot (i.e. parties that interact under a matching constraint are induced to cooperate more than is socially optimal). This paper identifies the conditions for such occurrences. Copyright © 2008 John Wiley & Sons, Ltd.     

The Research‐Practice Gap in Human Resource Management: A Cross‐Cultural Study

In this study, we examine the cross‐cultural differences in human resource (HR) managers’ beliefs in effective HR practices by surveying HR practitioners in Finland (N = 86), South Korea (N = 147), and Spain (N = 196). Similar to previous studies from the United States, the Netherlands, and Australia, there are large discrepancies between HR practitioner beliefs and research findings, particularly in the area of staffing. In addition, we find that interpersonal‐oriented aspects of HR practices tend to be more culturally bound than technical‐oriented aspects of HR practices. We interpret the differences using Hofstede's cultural dimensions (Power Distance, Individualism versus Collectivism, Masculinity versus Femininity, Long‐Term Orientation versus Short‐Term Orientation, and Uncertainty Avoidance). We discuss the overall nature of the science‐practice gap in HR management, and the implications for evidence‐based management. © 2014 Wiley Periodicals, Inc.
