- 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.
