Two Pitfalls of Linearization Methods

This paper illustrates two types of pitfalls when linearization methods are improperly applied. First, if we linearize the constraints before deriving the optimality conditions, the derived conditions are not correct up to first order. Second, even when we obtain the behavior of the economy that is correct to the first order, applying this behavior to welfare implications may lead to incorrect results. We also review different ways to avoid those pitfalls.     

UNION EFFECT ON THE USE OF NON‐REGULAR LABOR IN THE REPUBLIC OF KOREA

Our paper aims at analyzing the union effect on the externalization of employment relations, focusing on how labor unions affect management's strategic use of non‐regular labor within the Korean context of industrial relations. Our study presents several interesting implications. Firstly, the unions' motivator role for managerial use of non‐regular labor is more evident than its constrainer role. Secondly, union power exerts a “U‐type” impact on the use of indirect non‐regular labor, while affecting directly employed non‐regular labor in a positive linear way. Thirdly, labor unions in large establishments are more active and influential in representing their members' interests than their counterparts in small establishments with limited financial resources. In particular, the interactive function of the union's power and union leaders' attitudinal inclinations is found to be significant in the negative direction among large establishments.     

Broad‐Based Employee Stock Ownership: Motives and Outcomes

Firms initiating broad‐based employee share ownership plans often claim employee stock ownership plans (ESOPs) increase productivity by improving employee incentives. Do they? Small ESOPs comprising less than 5% of shares, granted by firms with moderate employee size, increase the economic pie, benefiting both employees and shareholders. The effects are weaker when there are too many employees to mitigate free‐riding. Although some large ESOPs increase productivity and employee compensation, the average impacts are small because they are often implemented for nonincentive purposes such as conserving cash by substituting wages with employee shares or forming a worker‐management alliance to thwart takeover bids.     

What Shapes Assessment of Ability to Pay for Children's College Education?

Many parents have concerns about the cost of their child's college and lack information about preparing for those expenses. Parents' assessment of ability to pay for college are likely to influence their investments in a child's education, and may in turn affect the child's educational commitment and attainment. These potential outcomes lead us to investigate what accounts for parents' assessment. We use logistic regression to analyze data collected from mothers with newborn children (N = 2,566). The findings demonstrate that the mother's assessment of ability to pay for the child's education are significantly associated with material hardship experiences, financial management skills, educational expectations, and her education level. We discuss research and policy implications of promoting positive financial assessment for college early.

危机后的金融体系框架——全球金融改革及其对于韩国的意义

在设计“危机后金融体系架构”时，我们会想到三个支柱：金融产业、金融市场（尤其是资本市场）以及金融监管。在讨论架构问题时，我将首先将注意力集中于全球金融市场，其次，也更重要的是，如何建设韩国的金融体系以反映它的经济和金融市场特性。我希望，即使将本文中的“韩国”替换为“中国”，它仍然能够为考虑“最适合于中国的中国金融体系架构”提供一个框架。我们必须记住，在全球趋势与国内特征之间取得平衡远比看起来困难。不过，无论它有多么困难，这都是我们必须努力的方向。从政策制定者的角度来看，最具有挑战性的议题就是处理系统性风险。各个国家的系统性风险来源是不同的．因此每个国家都必须建立一个能够最好地识别与管理其系统性风险的监管范式，尤其是宏观审慎性监管。     

A study on the subjective symptoms of the ageing process in middle-aged men: effects of socio-economic status,diet and health care behaviour*

In order to investigate the factors influencing the ageing process of middle-aged men, different environmental variables including socio-economic status, diet, smoking and drinking were studied as possible determinants of the ageing process. Six hundred and forty-seven Korean men over 40 years of age were studied. Frequency, chi-square, t-test, and stepwise multiple regression analyses were employed to identify the significant variables. As a result of the analyses, occupation and smoking were found to be the most influential factors. In short, those who did not refrain from smoking and had professional jobs experienced early symptoms in the ageing process.     

Accounting for Income Taxes: Early Adoption Issues

This study investigates whether the revised AASB 1020 Income Taxes was adopted early by Top 100 publicly listed companies in Australia between 2000 and 2004. We found that only three of the companies adopted the revised standard before its implementation date of 1 January 2005. Interviews with senior company representatives indicated that the three companies had quite different reasons for early adoption. Non-early-adopting companies had considered that the revised standard would not make a material difference to their reporting results. Tax consolidations and the impending international financial reporting standards were regarded as more important issues.
