The effect of the car-parazzi system on traffic accidents in Korea

In 2001 and 2002, the Korean government rewarded around $3 to civilians who photograph and report violations of traffic rules. This so-called ‘car-parazzi system’ was such a success with well over 4 million cases reported until its abolition. Our empirical results found that the car-parazzi system was much effective in significantly reducing the death tolls by traffic accidents.     

Native American casino marketing on the web

The Internet and its component, the World Wide Web (WWW or Web), as well as the casino industry grew tremendously in the United States in the past decade. While there are various estimates about the future size of the Internet and the casino market, all agree that the two will continue to grow substantially. However, very few studies have discussed Internet use within the casino industry. This study reviewed 58 Class III Native American casino web sites. Content areas analyzed included introduction to the casino organization, local destination attractions, food and beverage services, accommodations, entertainment and recreation facilities, maps and directions to casinos, links to related commercial and regulatory agency web sites, and user friendliness. Web site features were evaluated based on marketing mix and principles.     

Foreign ownership and the credibility of national rating agencies: Evidence from Korea

By analyzing bond price reactions to rating changes in Korea, this study adds a new angle to the existing literature on Global Rating Agencies (GRAs, i.e. Moody’s, S&P’s, Fitch) with higher reputation/independence vs. National Rating Agencies (NRAs) with more in-depth local knowledge. Faced with substantial regulatory burdens, GRAs have chosen to operate indirectly in the Korean domestic market by acquiring local NRAs. In our event study, cumulative abnormal returns following downgrades by a wholly domestically owned NRA tend to dominate those from downgrades by two affiliates of GRAs. This casts doubt on the additional information value of reputation capital acquired through GRA ownership as perceived by emerging markets.     

Financial Reporting Opacity and Expected Crash Risk: Evidence from Implied Volatility Smirks

The recent financial crisis has stimulated a renewed interest in understanding the determinants of stock price crash risk (i.e., left tail risk). Recent research shows that opaque financial reports enable managers to hide and accumulate bad news for extended periods. When the accumulated bad news reaches a certain tipping point, it will be suddenly released to the market at once, resulting in an abrupt decline in stock price (i.e., a crash). This study extends this line of research by examining the impact of financial reporting opacity on perceived or expected crash risk. Prominent economists, such as Olivier Blanchard, argue that removing the perception of tail risks (in addition to realized tail risks) is crucial in restoring investor confidence and stabilizing the stock market. Using the steepness of option implied volatility skew as a proxy for perceived crash risk, we find that accrual management, the presence of financial statement restatements, and auditor‐attested internal control weakness are all positively and significantly associated with the level of perceived crash risk. Our results suggest that improving financial reporting transparency is an important mechanism for firms and policymakers to reduce the perception of tail risks and stabilize the stock market.     

Line and HR executives' perceptions of HR effectiveness in firms in the People's Republic of China

This paper examines the differences in perceptions of the importance and effectiveness of human resources (HR) practices in firms operating in the People's Republic of China. The major finding is that while there are no significant differences between HR and line executives' perceptions of the importance of each functional area in human resource management (HRM), there are significant differences between line and HR executives' perceptions of the effectiveness of these areas. Line and HR executives both view the issue of securing, developing and maintaining human resources as a critical issue for the execution of daily operations and long-term strategic plans. However, line executives perceive HR performance effectiveness as significantly lower in these functional areas than HR executives do. Therefore, HR departments are not meeting the performance expectations of line executives. There are three possible reasons for the poor performance of HR departments. First, government intervention may limit HR departments' ability to act strategically. Second, HR departments may not have enough power to act strategically. Third, HR departments may have few capabilities to respond to line executives' demands.     

The Rising Supply of College Graduates and Declining Returns for Young Cohort: The Case of Korea

Abstract

This study analysed the effect of an increase in the supply of youth college graduates, in terms of the return on education. The rate of return on education in Korea substantially dropped from 1983 to 1994. Since then, however, the declining trend of the rate of return on education stopped and turned upward. The rate of return has declined especially for college graduates, and such a decline has been most prominent for young cohorts, among college graduates, since 1987. The observed trend of the rate of return appears to be related to the sharp increase of labour supply of college graduates since the mid 1980s.

The elasticity of substitution between education levels and age groups was estimated in this study, using a generalized demand-supply model. The effects of relative supply of college graduates (as a whole and by age) on the relative wages of college graduates by age were analysed under the assumption of constant skill-biased technological change. As it turned out, the relative college graduates’ labour supply of each age group had large bearings upon relative wages of each corresponding group, while the relative labour supply of all college graduates did not. It implies that labour is an imperfect substitute, not only between education levels but also between age groups.

Thus, as youth college graduates’ supply increases, there needs to be a corresponding demand increase for them, to avoid the drop in the wage or employment level for them. Therefore, to tackle with the issues of youth labour market, such as youth unemployment, separate policies targeting the youth group are called for.     

How the Rapid Development of VoIP Technologies Affects Consumer Welfare and the Market

Abstract

The impact of Voice over Internet Protocol (VoIP) growth on other telecommunication services, such as landlines and mobile telephony, has gained significant interest in Korea recently. An emerging alternative to landline telecommunications, VoIP is experiencing explosive growth in demand and is providing significant economic utility to consumers. The rapid growth of smart phones has also created a considerable amount of controversy regarding the potential impact of VoIP on the mobile phone market. This study provides quantitative estimations of consumer surplus for landline, mobile and VoIP services in the Korean telecommunications market using monthly call data from January of 2006 to June of 2009, a period when VoIP services grew rapidly. Empirical analyses are conducted to estimate consumer surplus based on the demand functions of each telecommunication service. Additional analyses are conducted on consumer surplus change as well. Policy implications for the rapid growth of VoIP and its impact on consumer surplus change are also discussed.     

The Evolution of Enterprise Unionism in Japan: A Socio‐Political Perspective

This article proposes an alternative framework for understanding enterprise unionism by emphasizing political dynamics and the role of the state in labour relations. Our framework delineates the strategic behaviour patterns of each of the tripartite IR actors under collective bargaining. It maintains that the initial period of the collective bargaining era constituted a critical juncture for state labour policy that occurred in distinctive ways in different countries and that these differences played a central role in shaping the different union structures in the following decades. Our historical analysis shows that unlike its Western counterparts, the Japanese state was able to eradicate the horizontal union movement at the onset of the collective bargaining era because of its advantages as a late developer and Cold War politics, which resulted in enterprise unionism in Japan.

New development: A new COFOG for South Korea

The South Korean government's Classification of the Functions of Government (COFOG) is grounded in the System of National Accounts (SNA), rather than Government Finance Statistics (GFS). This article explains why a GFS-based classification might be beneficial to South Korea for the purposes of fiscal management and the comparison of government expenditures with other countries.
