- Developing a Small Scale Quarterly Dynamic
Projection Model of Korea, the United States, the Euro Area and Japan Economies
Muhwan Park
Reflecting a recent trend in the development of dynamic
stochastic general equilibrium (DSGE) models as a macroeconomic
analysis tool, this paper aims to construct a global
dynamic projection model (DPM) based on a micro-foundation for
economic forecasting. In line with this purpose, we developed a small-scale quarterly
dynamic projection model of Korea, the United States, the Euro
area and Japan economies, in which the key macroeconomic
variables were output gaps, inflation rates, short-term interest
rate and exchange rates. We also introduced a financial variable
in the form of a bank lending attitude variable into the model to
allow for financial-real linkages. The model is estimated over the
sample period of 2000Q1 to 2012Q4 using Bayesian techniques.
The Bayesian estimation model shows that it is useful for short
and medium-term forecasting in the sense of ex-post estimates,
effective forecasting memory, and root mean squared errors in
intra and out of sample forecasts.

- This paper studies optimal interest rate feedback rule in an
economy with heterogeneous price rigidity and durable goods.
Many literatures document that the price of durable goods is
more flexible than that of nondurable goods. Our analysis builds
on the New Keynesian framework where nondurables price is
sticky and durables price is flexible. Our findings about the
optimal interest rate feedback rule in the model can be explained
as follows: Firstly, the optimal interest rate feedback rule yields
the level of welfare close to that under the Ramsey optimal
policy even in this model. In addition, the primary feature of the
optimal rule is responding to sticky-price inflation only, rather
than aggregate price inflation. This is because there does not exist
a trade-off between stabilizing sticky nondurable goods price
inflation and following the Ramsey optimal path of each sectoral
output. However, responding to aggregate price inflation causes
larger welfare loss through the distortion of the relative price of
durable goods.

- The Analysis on the Cost Sharing System
in Korean Medicaid: Copayment or Coinsurance
Yong-Ju Lee
The Korean version of Medicaid has been playing an important
role in guaranteeing a minimum health care for the underprivileged,
but it has experienced severe loss of efficiency due to
moral hazard. In order to fix this problem, the Korean
government introduced the copayment system to the category-1
recipients who had not paid any money for medical treatment
until 2007. But it seems that, even after the reform, the negative
problems persist with no significant improvement. Hence, some
propose the coinsurance system as an alternative to the current
copayment system. This paper analyzes the effects of these cost
sharing systems in Medicaid in the frame of standard health
insurance, and studies which form of cost sharing system is
optimal. Our model concludes that copayment and coinsurance are
equivalent in terms of medical treatment, and Medicaid with
copayment second-order stochastically dominates Medicaid with
coinsurance.

- The effects of the minimum wage policy have been controversial
in Korea with an increasing gap between the rich and the poor
since the Asian financial crisis. Most studies in Korea have
focused on the disemployment effects of higher minimum wages
and the negative effects of the policy in Korea. This study looks
at the possible effects of the minimum wage policy on reducing
poverty rates, as measured by the number of people who fall
under the defined poverty threshold. We utilize a binary probit
model to analyze the Korean Labor and Income Panel Study data
and find that a higher hourly minimum wage can reduce the
probability of an individual falling under the poverty line.
