    Spurious Correlation in Testing for Asymmetric Information: The Case of Automobile Insurance Data
    Yong-Woo Lee
    Pages 3-16
  • Abstract ( Eng | Kor ) || PDF
    •    We examine the possibility of spurious conditional correlation in testing for asymmetric information in the context of the automobile insurance contracts. An important characteristic of insurance data is that the insurer can observe only claims, not accidents. As pointed in Chiappori(2000), this may cause a spurious correlation in the conditional correlation approach. In particular, it may be that certain losses are only covered under more comprehensive contracts and are only reported by a policyholder who has indeed purchased this more comprehensive insurance. Using a rich data set obtained from a major automobile insurance firm in Korea, we found out the possibility of spurious conditional correlation. Considering claims involving only bodily injuries enables us to overcome this problem. Using claims involving 2 vehicles is still susceptible to the problem.

    • Estimation and Forecasts of Korea's Potential GDP Growth Rate Using a Production Function Approach
      Mu Hwan Park


         This paper aims to estimate and forecast Korea's potential GDP growth rate which is considered as an important fundamental factor to forecast the major price variables in the actuarial model designed for a mid-term financial projection of National Pension. In line with this purpose, this paper examines a long-run growth trend of the Korean economy before and after the foreign currency and the global financial crises, focusing on a production function approach and attempts to forecast the potential GDP growth rate for the period of 2011~2016. The estimated potential GDP growth rates before and after the foreign currency and the global financial crises is 7.6~7.7%(1991~1997), 4.5%(2001~2007), and 3.8%(2008~2010) which shows about 3%p decline after the foreign currency crisis and 0.7%p decline after the global financial crisis, respectively. The potential GDP growth rate for the period of 2011~2016 is predicted to be 4.4% in 2011 and 4.1% in 2016 by following a successive decline path, which can be interpreted as a continuous drop in the factor inputs effects.

    • Aging Vulnerability Index of Korea
      Sejin Min


         Korea entered an aging society in 2000 and the country has been aging at one of the world's fastest rates. This paper introduces the 'Center for Strategic and International Studies (CSIS)' 'Aging Vulnerability Index', and calculates Korea's aging vulnerability index to compare the Korean aging problems with 12 other countries. The results show Korea's most vulnerable areas are the fast aging rate and the poverty of the olds. The implications from the study is that the government should abstain from expanding transfer payments, and encourage private pensions.

    Unemployment and the Asset Market for Jobs
    Yong Jin Kim
    Pages 81-105
  • Abstract ( Eng | Kor ) || PDF
    •    Search models of unemployment motivate analysis through a matching problem between two distinct groups in the economy: firms and workers. A question which arises is why can't workers circumvent search frictions by creating jobs themselves? Meanwhile, firms are able to supply vacant jobs perfectly elastically: how are vacancies sourced? I address these concerns in an environment where ex ante identical agents can create, buy or sell jobs, and assess the model quantitatively.

    • Analysis on the Dynamics of Current Account Distribution
      Sun-Bin Kim


         We undertake a quantitative analysis of the dispersion of current accounts in an open economy version of incomplete insurance model, incorporating important market frictions in trade and financial flows. Calibrated with conventional parameter values, the stochastic stationary equilibrium of the model with limited borrowing can account for about two-thirds of the global dispersion of current accounts. The easing of financial frictions can explain nearly all changes in the current account dispersion in the past four decades whereas the easing of trade frictions has almost no impact on the current account dispersion.

    • Gender Difference in Overconfidence: Evidence from the Foreign Language Scores in the Korean SAT
      Hun Young Yoo, Hailey Hayeon Joo


         This paper investigates whether there exists gender difference in overconfidence. By exploiting the data from the 1st year survey of Korean Education and Employment Panel (KEEP) in 2004 along with the Korean SAT scores on the foreign-language section in 2005, we compare actual and expected scores and then measure the dispersion between these two scores, based on which we build the index of overconfidence. Although the data show that boys on average tend to be overconfident about English test scores than girls, the estimation results suggest that this tendency is not statistically significant when the effects of other characteristics of students or those of their parents (such as parents' education) are properly controlled. Moreover, the impacts of most characteristics of students other than gender are statistically insignificant. The main contribution of this paper is about investigating the relationship of gender difference to overconfidence in a competitive environment that is one of the popular topics in recent economic researches, and confirming it with the test score data for the college admissions in Korea.

    • Seatbelt and Car accident fatality in Korea
      Beomsoo Kim, Ah-Ram Kim


         Korea experienced 591 auto accidents per day in 2008. As a result of auto accidents in 2008 16.1 people are dying every day and 929 people are injured. Controlled experiments in the lab showed wearing seat belt would reduce injury and even save lives. However, it is interesting to examine whether these lab results will be the same in the real world. It is the first study in Korea examining seat belt use rate and auto accident fatality using representative data. We use monthly auto accident fatality by 14 provinces and calculate fatality per driving 1,000 million kilometers as a dependent variable. Monthly seat belt use rates for the people involved in the auto accident comes from auto accident reports to the road traffic authority by 14 provinces. We use fixed effect econometric model to control time invariant endogeneity of the seat belt use rate. Region(province) fixed effects, Month fixed effect and year fixed effects were considered. The biggest change showed in year fixed effect. After controlling endogeneity of these sources we found 10% increase of seat belt use would decrease casualty per 1,000 million kilometers by 8.7%. However, we could not control individual level endogenity in this paper due to limited data availability.

    • Role of Financial Factors in Korean Business Cycle
      Kunhong Kim


         This study attempts quantitative analysis of the role of financial factors in the Korean business cycle. A New Keynesian Dynamic Stochastic General Equilibrium model of a Small Open Economy that incorporates financial frictions in the form of financial accelerator and three types of financial market shocks are constructed. Quantitative importance of financial frictions are investigated by estimating the model using a Bayesian Maximum Likelihood. Estimate of the elasticity of the external finance premium with respect to the leverage ratio is statistically significant, which implies that financial accelerator mechanism is working. Variance decomposition shows that financial shocks have played significant role in the variations of investment and output fluctuations.
