    • Discussion on Pareto Efficiency and Self-Stability of Weighted Majority Rules
      Semin Kim, Uzjune Kim


         We consider a Bayesian environment with independent private values and two possible alternatives. We characterize the set of weak Pareto efficient weighted majority rules. Based on the characterization, we discuss the connection between Pareto efficiency and self-stability of weighted majority rules.

    • Income Effects and Neonatal Health: New Evidence from the Coal Boom
      Beomsoo Kim, Jun Koo, Sunghoon Lim


         This study estimates the effects of income shock on health. We analyze infant birth weight and mortality in Kentucky, Ohio, and West Virginia during the 1970s using the sharp coal price increase as an exogeneous income shock. This variation has been used in several previous papers. Individual level natality data are used for the birth weight analysis and county level per capita income is instrumented with the value of coal reserves in the county. An exogenous $1,000 increase in income in 2015 dollars increased birth weight by 5.5 grams but it is not statistically significant. The numbers of low birth weight babies decreased by 0.1%p with an exogenous $1,000 increase in income but again statistically insignificant and 1.3% of the sample mean (7.6%). Since we examine miners mostly, our results might have limited generalizability to general population.

    • Income Types and Culture and Entertainment Expenses
      Bomi Kang, Kyung-woo Lee


         This paper analyzes effects of income types on culture and entertainment expenses (CEEs). Specifically, we regress the ratios of CEE to consumption and total expenses on capital, labor, and other incomes using the KLIPS for 2001-2017. We find a 1% increase in capital income raises the CEE-consumption and CEE-expenses ratios by 0.098%p and 0.062%p, whereas a 1% increase in labor income by 0.057%p and 0.024%p. We obtain similar results in various subsamples. Considering also that 1% of labor income far exceeds 1% of capital income for most households, our finding suggests that capital income has strong effects on CEE.

    • The Long-Term Labor Market Effects of Economic Policy Uncertainty at the Time of Graduation
      Hye Yoon Chung, Youjin Hahn, Seung Phil Lim


         We investigate the long-term effects of economic policy uncertainty on employment and wage for those who entered the Korean labor market between 1990 and 2014. Policy uncertainty has heterogeneous effects across education and gender. Male high school graduates experience stronger negative effects on employment in terms of both magnitude and duration compared to male college graduates. Among employed males, two-year college graduates experience a persistent negative effect on wages. Female high school graduates undergo an initial decrease in employment and female four-year college graduates suffer from a wage loss in their late career stage due to high policy uncertainty.

    • Deferring Graduation as Job Market Signaling
      Doo Hyung Yun, Jin Seok Park, Jaeok Park


         Due to the tough Korean job market for college graduates, it has become a universal phenomenon in Korea for college students to defer graduation. In this paper, we perform a game-theoretic analysis on delayed graduation, interpreting it as a signal sent by job applicants to the firm. We show that, when the job market is tough, there can exist a separating equilibrium in which applicants with high productivity put off graduation and those with low productivity graduate on time. In addition, there can exist pooling equilibria in which applicants of both types graduate or defer graduation. We compare the payoffs of participants in the three kinds of equilibria. We also discuss how the equilibrium will change as it becomes more difficult to get a job and as the cost of deferring graduation gets lower.

    • Detecting Multiple Bubbles in the Korean Housing Market and Housing Market Policy
      Yongjae Lee, Cheolbeom Park


         We apply the bubble test, proposed by Phillips, Shi and Yu (2015), to the apartment purchase price indices and apartment jeonse price indices in Korea. We find that multiple bubbles have existed in apartment purchase price indices and jeonse price indices for Korea, Seoul, six metropolitan cities and 25 districts in Seoul and that more bubble periods are estimated for apartment purchase price indices than apartment jeonse price indices. Estimated bubble periods from the apartment purchase price index of Seoul shows the highest accordance rate with the base of housing policy. Finally, movements of the interest rate affect the apartment jeonse price indices more strongly than apartment price indices.

    • A Study on Legislation for the Financial Groups in Korea from the Perspective of the Global Standard
      Sejin Min


         The bill on supervision of financial conglomerates is under review in the National Assembly. This study checks the facts about IMF¡¯s suggestion to Korea from the Financial Sector Assessment Program, and searches the regulatory cases of Australia and Germany. It turns out that the current level of Korean regulation on supervision of financial conglomerates, including the solvency calculation regarding non-financial subsidiaries, is not particularly low. Since it is important to properly supervise the financial conglomerates, evidenced from the global financial crisis, it may be beneficial to use Financial Holding Company Act to supervise the financial conglomerates, following IMF¡¯s suggestion.

    • A Short Guide to Machine Learning for Economists
      Ki Young Park, Jeong Won Ko


         With the development of various AI (Artificial Intelligence) techniques and increased availability of big data, ML (Machine Learning) is expected to become the essential technology that would affect many aspects of our economy and society. With this in mind, the purpose of this paper is to provide an overview of ML techniques with emphasis on its application to economics. Contrasting the key differences in ML techniques and econometric methodologies, we first explain the key techniques used in supervised learning, which are widely used in industry and academia. Then we provide a survey of recent economic research that uses ML techniques and introduce debates on its impact on labor market and the value of data. We conclude with discussing the current limitations of ML technique in terms of economic research, while we believe that ML will fruitfully complement the current methodologies of economics.

    • Effects of Uncertainty Shock on South Korea: A Regional Analysis
      Myungkyu Shim, Youngjoo Lim, Minseung Kim


         According to previous studies, the real economy of South Korea is not significantly affected by an increase in economic policy uncertainty(EPU), but is affected by an increase in financial uncertainty(FU). Using a Vector Autoregression(VAR) analysis, this paper analyzes if this finding also appears at the regional level. First of all, an increase in domestic economic policy uncertainty does not significantly affect the industrial production and unemployment rate of both regional and aggregate economy of South Korea. An increase in uncertainty from the asset markets (financial uncertainty), in contrast, has a significantly adverse effect on the industrial production and unemployment rate in most regions, while the effects do not seem to be significantly different across the regions. These results are robust to global EPU and VIX.
