- This paper considers a dynamic general equilibrium model of a
small open two-period endowment economy with tradable and
non-tradable goods. Under some mild assumptions regarding the
form of the representative agent's inter-temporal utility function,
it is shown analytically that a temporary positive output shock
in the tradable good sector increases national saving and
improves the current account balance whereas a similar positive
output shock in the non-tradable good sector reduces national
saving and deteriorates the current account balance if the
inter-temporal elasticity of substitution between the current and
future consumption is greater than the intra-temporal elasticity of
substitution between the tradable and non-tradable good
consumption.

- Division of Labor and Contests
Sung-Hoon Park
We examine how changes in division of labor affect rent
dissipation and expected payoffs for parties in contests. To do
so, we model three contests: a contest with parties (CP), a
two-stage contest with delegation (CD), and a two-stage contest
with parties and delegation (CPD). Then we obtain a unique
equilibrium in each contest, and compare the equilibrium of CD
to those of CP and CPD. The results are as follows. First,
compared to rent dissipation in CP and that in CPD, rent
dissipation in CD is low. Second, compared to the sum of
expected payoffs for parties in CP and that in CPD, the sum in
CD is high. The results may be referred to as the division of
labor in contests.

- This study analyzed whether the higher mortality of weekend-born
children compared to weekday-born are due to lowered
staffing ratio over the weekend or unobserved health condition
of newborns. Unlike the previous studies we use the census of
US births and truly exogenous birth timing by focusing on
vaginal deliveries without induction or stimulation. The
statistically significantly higher mortality rate for weekend-born
babies was no longer observed when birth weight was included
as a proxy for unobserved health condition and these results are
robust across various samples and different locations. Our
findings are robust to high risk groups such as cesarean section
and low birth weight samples.

- The Effects of Foreign Investors on the Korean Equity Market during the 2007~2008 Financial Crisis
Gab-Je Jo
This paper investigates the effects of foreign equity investment
on the Korean market during the 2007~2008 financial crisis.
The empirical results indicate that foreign investors show
positive feedback trading behavior and domestic institution
investors show negative feedback trading behavior. In terms of
volatility, I have found evidence that foreign investors' net
selling behavior tends to increase market volatility, while net
buying activity by domestic investors increases volatility in the
market.

- How Do We Utilize a New 'Final Demand-Final Output Model' in Economic
Analysis?: Based on the Nature and Usefulness of the Model
Ho Un Gim
On the grounds of the latest research findings and results
from the models of input-output (IO) and output-output (OO),
which was first developed by the author as the alternative model
of the IO model, the specific objectives of this paper can be
summed up as follows.
(1) We develop a new final demand-final output (FF) model as
the another alternative model of the traditional IO model and
verify the nature, economic implications and usefulness of the
model.
(2) We derive the varied types of multipliers, linkage and
induced economic effects for the newly developed FF model.
(3) We examine the effectiveness and usefulness of the
alternatively developed FF model through counting the various
sectoral multipliers and induced effects based on raw data of
¡º2010 Input-Output Tables¡» complied by the Bank of Korea.
Moreover, the Spearman's rank correlation coefficients, , are
empirically counted to observe the relevant structural economic
characteristics of each endogenous sector between types of
multipliers, and between linkages and induced effects.
