    • Kim Young-ran Act and Bribery Deterrence
      Eunjee Joo, Yong-Ju Lee


         This paper pinpoints the clauses of self-report and immunity in ¡°Kim Young-ran Act (KYR)¡± and game-theoretically analyzes the effectiveness of those clauses as a bribe deterrence mechanism. Contrary to an idea presented in the literature, KYR contains clauses that public employees are obligated to report their bribe taking and are immune from punishment if they immediately self-report bribe taking. That is, incentives are installed for the bribe taker to report the bribe giver. We, based on the methodology of Dufwenberg and Spagnolo (2015), develop a model of extortion bribes and analyze how the clauses of self-report and immunity under KYR play a role in deterring bribery. In particular, we focus on the emergence of a socially very bad equilibrium (¡°Ingrained Bribery Equilibrium¡±) in the context of one-sided repeated game where a civil servant repeats the same task for a long time, characterize the parameter region for the equilibrium, and draw some policy implications on how to mitigate the emergence of the equilibrium under KYR. We also discuss how variations of KYR affect bribery and show that the parameter region for the Ingrained Bribery Equilibrium may shrink with a different incentive mechanism.

      Beomsoo Kim, Hyuncheol Yun


         We examine the impacts of new bank loan guideline effective on December 15 2015 on housing prices. We use regression discontinuity model to capture clean effects. We found the result that new guideline lowered the apartment price by 1.4% in Seoul, Gyeonggi and Incheon. Expensive housing defined price above 0.9 million won showed 13.8% drop in price while cheap housing did not show statistically significant change. There was big variation in terms of policy impact across region as well.

    • Substitute and Complementary Relationships between Online and Offline Courses in Foreign Language Education
      Sung Ju Lee, Jinook Jeong, Yun Jeong Choi


         With the advancement of information and communication technologies, online courses have increased as a new channel of education. This study contributes to the existing literature by providing empirical evidences for the substitute or complementary relationship between online and offline courses. The results show that while offline and online courses in test preparation courses such as TOEFL and TOEIC were neither substitute nor complement, they were complementary to each other in general English courses such as speaking and writing courses. Different relationship between online and offline education services depending on subject characteristics provides implications for other markets as well as language education market.
