Capital mobility and environmental standards: Racing to the bottom with multiple tax instruments

This paper investigates the possibility of a ‘race to the bottom,’ under which intergovernmental competition for mobile capital leads to inefficiently lax environmental standards. A model is constructed in which independent welfare-maximizing governments regulate pollution emissions from production activities, while taxing residential labor and mobile capital to finance public good expenditures. A race is shown to exist in the sense that a ‘central planner’ could improve welfare in every country by requiring that each government tighten its environmental standards. The analysis also shows that the tax-financed public good is underprovided in equilibrium, but it is argued that this problem may be less severe than the race-to-the-bottom problem.     

Regression Analysis under Probabilistic Multi‐Linkage

Linkage errors can occur when probability‐based methods are used to link records from two distinct data sets corresponding to the same target population. Current approaches to modifying standard methods of regression analysis to allow for these errors only deal with the case of two linked data sets and assume that the linkage process is complete, that is, all records on the two data sets are linked. This study extends these ideas to accommodate the situation when more than two data sets are probabilistically linked and the linkage is incomplete.     

Postponement strategy for international transfer of products in a global supply chain: A system dynamics examination

This paper contributes to research on “postponement” strategy in the context of a global production–distribution system of an automobile manufacturer. It proposes a model that integrates multiple considerations germane to global supply chains. Postponement is important in this context because it is necessary to consider international transfers and tariffs, and it is important to appropriately account for the impact of postponement on total costs. Consideration of several key variables such as shipping point, customs tariff, and cost differences between countries is essential to derive full benefits from postponement strategy in global supply chains. International transfer of goods among countries in global automobile industry is complex and dynamic because of the multitude of factors that must be considered. The paper develops insights regarding postponement strategy in global supply chains via a system dynamics simulation model. The model draws on the experiences of a Korean automobile manufacturer with operations in developing and developed countries.     

Adam Smith's and Douglass North's Multidisciplinary Approach to Economic Development

This article aims to point out Adam Smith's and Douglass North's multidisciplinary approach to economic development and history. Based on a philosophical link of methodological issues, Smith and North shared a conceptual framework and explanatory principles in common as well as similar historical illustrations. In terms of the use of comprehensive and integrated models of society, politics, and economy, they presented that economic development relies on how far congenial both institutional environments and sociocultural values of justice, liberty, security, and equality are to economic agents, allowing the interplay between economic performance and polity/culture. Meanwhile, these suggest a bridging role between old and new institutionalism, and, more importantly, a revival of Smithian moral philosophical tradition in the history of economics.     

How does industry use social networking sites? An analysis of corporate dialogic uses of Facebook,Twitter, YouTube,and LinkedIn by industry type

This study examines the corporate dialogic uses of four types of social networking sites (SNSs) (Facebook, Twitter, YouTube, and LinkedIn) with the public and their differences by industry type. The results suggest that corporations have integrated SNS uses, and use SNSs in different ways according to the characteristics and purposes provided by each SNS. In most cases, retailers and communications and transportation companies actively use SNSs and frequently interact with the public. In addition, Facebook was the leading tool for the dialogic feedback loop, as the dialogic interaction index of Facebook was much higher than that of Twitter.     

DIVORCE LAW REFORMS AND DIVORCE RATES IN THE USA: AN INTERACTIVE FIXED‐EFFECTS APPROACH

This paper estimates the effects of unilateral divorce laws on divorce rates in the USA from a panel of state‐level divorce rates. We use the interactive fixed‐effects model to address the issue of endogeneity due to the association between cross‐state unobserved heterogeneity and divorce law reforms. We document that earlier studies in the literature do not fully control for unobserved heterogeneity and result in mixed empirical evidence on the effects of divorce law reforms. While reconciling these conflicting results, our results suggest that divorce law reforms have temporal positive effects on divorce rates, thus confirming the 2006 findings of Wolfers. Via simulation experiments, we assess the degree to which faulty inclusion or faulty exclusion of interactive fixed effects affects the policy effect estimators. Our results suggest that faulty inclusion only results in efficiency loss whereas faulty exclusion causes bias. Copyright © 2013 John Wiley & Sons, Ltd.     

The influence of trade union Disability Champions on employer disability policy and practice

Disability Champions are a new type of lay workplace trade union activist, whose role is to encourage employers to audit and improve disability policies and offer independent advice and guidance on disability issues to employees. Drawing on a survey of the population of Disability Champions, this article assesses Disability Champion influence on employer disability policy and practice. While the majority of Disability Champions report having had a positive impact, they report greater influence on employer willingness to conduct disability audits and to amend and improve employer equal opportunities practices with regard to disability than employer willingness to make reasonable adjustments. The analysis also identifies several factors that are likely to be important in improving Disability Champion effectiveness. Overall, the results suggest Disability Champions have the potential to enhance the ability of unions to represent disabled people and help manage disability issues within the workplace. The article makes a theoretical contribution to Disability Champion roles by further developing the ‘Activity‐Support‐Characteristic’ framework for the antecedents of new union representatives' effectiveness.     

Economic cost–benefit analysis of the addictive digital game industry

This study attempts to estimate the economic costs and benefits of the addictive digital game industry. Addiction to digital games induces economic costs such as increase in crime, facilities investments for curbing addiction, increase in counselling costs and other welfare losses. As a case study, we investigate the digital game industry in South Korea which is known to have one of the highest rates of game addiction. According to our calculations, the annual cost of game addiction is estimated to be approximately $3.5B while the annual benefit is approximately $24.3B ($3.7B for addicted user market). The proportion of the total costs to total benefits from the game industry is an alarming 14% (95% for addicted user market). We offer some policy recommendations.     

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.     

Medical costs in patients with heart failure after acute heart failure events: one-year follow-up study

Aims: This study investigated annual medical costs using real-world data focusing on acute heart failure.

Methods: The data were retrospectively collected from six tertiary hospitals in South Korea. Overall, 330 patients who were hospitalized for acute heart failure between January 2011 and July 2012 were selected. Data were collected on their follow-up medical visits for 1 year, including medical costs incurred toward treatment. Those who died within the observational period or who had no records of follow-up visits were excluded. Annual per patient medical costs were estimated according to the type of medical services, and factors contributing to the costs using Gamma Generalized Linear Models (GLM) with log link were analyzed.

Results: On average, total annual medical costs for each patient were USD 6,199 (±9,675), with hospitalization accounting for 95% of the total expenses. Hospitalization cost USD 5,904 (±9,666) per patient. Those who are re-admitted have 88.5% higher medical expenditure than those who have not been re-admitted in 1 year, and patients using intensive care units have 19.6% higher expenditure than those who do not. When the number of hospital days increased by 1?day, medical expenses increased by 6.7%.

Limitations: Outpatient drug costs were not included. There is a possibility that medical expenses for AHF may have been under-estimated.

Conclusion: It was found that hospitalization resulted in substantial costs for treatment of heart failure in South Korea, especially in patients with an acute heart failure event. Prevention strategies and appropriate management programs that would reduce both frequency of hospitalization and length of stay for patients with the underlying risk of heart failure are needed.
