The economic burden of kidney disorders in Korea

Aims: To estimate the economic burden of kidney disorders in Korea.

Materials and methods: The economic burden of kidney disorders was estimated using a prevalence-based approach. Related kidney diseases in patients with kidney disorders (RPWKD) were defined using codes from the tenth International Classification of Disease (E70–E90, F30–F48, F60–F69, F90–F99, K65–K67, N00–N08, N17–N19, and N30–N39). All diseases in patients with kidney disorders (APWKD) were defined as kidney disorders that involved all disease codes. Economic costs were divided into direct costs (medical costs and non-medical costs) and indirect costs (productivity loss because of morbidity and premature mortality).

Results: The prevalence of kidney disorders increased from 0.08% (2008) to 0.11% (2011). The total economic burden of RPWKD also substantially increased from $898.9 million (2008) to $1.43 billion (2011). This ～59.4% increase in the economic burden was equal to 0.12% of the Korean gross domestic product. The economic burden of APWKD also increased during the study period: $1.06 billion (2008), $1.23 billion (2009), $1.44 billion (2010), and $1.46 billion (2011).

Conclusions: The present study provides the first data regarding the economic burden of kidney disorders in Korea. The findings support the need for early intervention services and prevention programs to prevent, identify, and manage kidney disorders.     

Welfare-improving cooperation with a consumer-friendly multiproduct corporation

We consider a multiproduct corporation that adopts consumer-friendly activities and cooperates with single-plant firms for improving welfare. We show that full cooperation is socially beneficial if products are strong complements, whereas partial cooperation with higher consumer-friendly activities is beneficial if products are substitutes. We also examine a sequential choice game of endogenous cooperation in which the multiproduct corporation can induce (partial or full) cooperation and show that our findings are still consistent at equilibrium. We finally compare different ownership of the single-plant firms and find that foreign ownership decreases the benefits of cooperation.     

Benchmarking and Transparency: Incentives for the Pharmaceutical Industry’s Corporate Social Responsibility

With over 2 billion people lacking medicines for treatable diseases and 14 million people dying annually from infectious disease, there is undeniable need for increased access to medicines. There has been an increasing trend to benchmark the pharmaceutical industry on their corporate social responsibility (CSR) performance in access to medicines. Benchmarking creates a competitive inter-business environment and acts as incentive for improving CSR. This article investigates the corporate feedback discourses pharmaceutical companies make in response to criticisms from benchmarking reports. It determines whether these responses are part of a healthy process in increasing access to medicines or a barrier to improvement. A qualitative analysis on the feedback the industry provided was performed, and the responses seen in these statements were grouped by analysing the language used, the ideas portrayed and atti- tudes of the companies. Increasing transparency through benchmarking is a powerful tool which reveals the industry’s shortfalls to the public, affects the decisions of socially responsible investors, and is a risk to their financial bottom line. This article demonstrates the importance of benchmarking and transparency in creating inter-business competition and the translation of these responses to actual access to medicine practices.     

New evidence on what happens to CEOs after they retire

I analyze directorships held by CEOs who retired during the periods 1989–1993, 1995–1999 (before the Sarbanes–Oxley Act) and 2001–2005 (after the Sarbanes–Oxley Act). My results suggest that retired CEOs became less popular on boards after the Sarbanes–Oxley Act. In addition, although pre-retirement accounting performance helps explain the number of outside directorships a retired CEO held in the 1989–1993 sample, as Brickley et al. (1999) have found, it does not explain this number for the 1995–1999 sample and 2001–2005 sample. Third, a company's stock performance during a CEO's tenure is negatively related to the number of outside directorships only in the 2001–2005 sample. Fourth, the number of outside directorships is positively correlated with the size of a retired CEO's original firm before the Sarbanes–Oxley Act, but this is not the case after the Sarbanes–Oxley Act. Finally, if retired CEOs worked in regulated industries, their probability of serving at least one outside directorship 2 years after retirement falls by 21% in the 1989–1993 sample. However, this negative effect is marginally significant in the 1995–1999 sample, and vanishes in the 2001–2005 sample.     

The impact of product knowledge on consumer product memory and evaluation in the competitive ad context: The item‐specific‐relational perspective

Research evidence to date suggests that the combined presence of item‐specific and relational processing is necessary to induce higher memory performance of the target ad and proper evaluation of the target brand. This elaborative processing, however, requires cognitive capacity. In this paper, an item‐specific‐relational processing framework was employed to explain the roles of consumer product knowledge in the competitive and non‐competitive ad contexts. Findings from an experimental study suggest that high‐ and low‐knowledge consumers differed in product memory and evaluation in competitive and non‐competitive ad contexts. Such differences could be explained by consumers' engaging in item‐specific and/or relational processing depending on whether target brand information was presented with or without information on competing brands. It appears that competitive ad context would benefit low‐knowledge consumers by serving as a reference. In contrast, high‐knowledge consumers did not seem to be affected by ad context. Both theoretical and managerial implications are discussed. © 2011 Wiley Periodicals, Inc.     

Sovereign wealth fund investment and the return-to-risk performance of target firms

This paper investigates the relationship between sovereign wealth fund (SWF) investment and the return-to-risk performance of target firms. Specifically, we find that target firm raw returns decline following SWF investment. Though risk also declines following SWF investment, we find that SWF investment is associated with a reduction in the compensation of risk over the 5 years following acquisition. Firm volatility decomposition suggests that idiosyncratic risk is what mainly drives these impacts toward decline. Employing a multinomial logit framework wherein combinations of target returns and risk movements are categorized, we see that, in cases of foreign investment, SWFs’ target firm performance most closely resembles that of other government-owned firms. The observed results are inconsistent with predictions of higher volatility and improved returns due to monitoring firm activities from the institutional investor literature. This suggests that SWFs may not provide some of the benefits that are offered by other institutional investors.     

FURTHER EVIDENCE ON REAL INTEREST RATE EQUALIZATION: PANEL INFORMATION,NON‐LINEARITIES AND STRUCTURAL CHANGES

Previous studies applying traditional unit root tests generally have difficulty providing widespread evidence supporting the real interest rate parity hypothesis (RIPH). This paper aims to analyse the empirical fulfilment of RIPH for 17 OECD countries by employing many recently developed unit root tests. Power of the tests is raised by taking different approaches, such as using cross‐sectional information, accounting for non‐linear adjustment towards the equilibrium and allowing for structural changes. The combined results of the tests using panel information show that broad evidence in favour of RIPH prevails for 13 of the 17 countries. By contrast, univariate tests fail to make widespread rejections of the unit‐root hypothesis. Our evidence reveals a high degree of market integration for developed countries, and the effect of monetary policies as a stabilization tool might be limited at least in the long run.     

Political Economy of Course Evaluations

Professors Hansen and Kelley suggest practical guidelines for implementing course evaluation systems, drawing upon their experience at the University of Wisconsin. They develop a model to conceptualize course evaluations in the context of the professor's decision-making framework, focusing upon the allocation of time between teaching and research. Costs and benefits associated with collecting evaluations are considered, and ways of minimizing the former and maximizing the latter are suggested.     

Asymmetric customer–supplier relationship development in Taiwanese electronics firms

The purpose of this paper is to analyse the relationship development stages of asymmetric customer–supplier relationships. The structure of relationships between larger customers and smaller suppliers has been the focus of a number of studies in IMP (Industrial Marketing and Purchasing Group) research. But, there is a paucity of research that examines development stages in relationships where a difference in size between the parties exists. The paper links the characteristics of asymmetric customer–supplier relationships and the relationship development stages through a literature review. The findings from a set of five in-depth case studies of asymmetric customer–supplier relationships in the Taiwanese electronics industry are presented. The case studies involved 50 semi-structured interviews with customer and supplier executives and, in addition, multiple observations of customer–supplier interactions within each case study. Individual and cross-case analysis was conducted to examine the links between the characteristics of asymmetric customer–supplier relationships and relationship development stages. The findings revealed that asymmetric customer–supplier relationships in the Taiwanese electronics industry were very unbalanced and vulnerable in the exploratory stage of development. In the developing stage relationships were more likely to develop if suppliers and customers mirrored each other's behaviour and echoed each other's priorities. In the stable stage suppliers and customers worked on shared and balanced contributions to the relationship. The paper contributes to the understanding of how smaller suppliers and larger customers can identify and develop key sets of relationship characteristics through the exploratory, developing and stable stages of asymmetric relationship development from both customer and supplier perspectives.     

Pitting real options theory against risk diversification theory: International diversification and joint ownership control in economic crisis

This study examines how MNE divestment decisions differ according to real options vs. risk diversification perspectives. We develop competing hypotheses in relation to international diversification and joint ownership control. Empirical results give consistent support to the real options perspective. We find that large MNEs with greater international diversification are less likely to divest their subsidiaries during times of economic crisis. The negative effect of joint ownership control is however manifested in both crisis-stricken and non-crisis country subsidiaries as well as in their interaction effect.
