- This study estimates the tail index of firm size distribution in
Korea, by fitting its right tail to a scaled Log phase-type
distribution. We use the sample of statutory-audited firms,
including both financial and non-financial companies. Regardless
of the choice of proxy for firm size, our estimator fits the extreme
tail of the distribution better than the previous methods, such as
the popular Hill estimator. The estimates of the tail index vary
across different firm size measures and the economic statuses,
indicating that firm sizes do not necessarily follow the Zipf¡¯s law.
Furthermore, the upper tail of the firm size distribution in Korea
becomes thicker during the financial crises in 1997 and 2007-2008. This adds to the evidence that the allocation of resources
across firms is affected by financial crises.

- The Comovement Problem between Durable
and Nondurable Sector in a New Keynesian
DSGE Model and the Role of Intratemporal
Adjustment Cost
Suk Gee Choi, Kwang Hwan Kim
This paper resolves the sectoral comovement problem that
arises in response to a monetary shock in a two sector New
Keynesian Dynamic Stochastic General Equilibrium model
consisting of sticky priced nondurable consumption sector and
flexible priced durable sector. The durable sector produces durable
consumption goods and investment goods for two sector. So the
comovememt problem expands from between nondurable and
durable consumption or consumption and investment to among
nondurable consumption, durable consumption and investments
for two sector. We find that the sticky wage which is commonly
incorporated in the New Keynesian model to resolve the
comovment problem cannot solve the problem alone and makes it
even worse and that the intratemporal adjustment cost in the
durable sector is additionally needed to resolve the comovement
problem.

- Economic Liberty and Social Justice:
A Critical Review on Neoclassical Liberalism
Jaehong Hwang, Pil Kyoo Jo
Neoclassical liberalism refers to the recent movement of
liberalism toward the integration of classical liberalism and
egalitarian liberalism. While, like classical liberalism, neoclassical
liberalism holds that economic liberties should be recognized as
basic rights, it attempts to morally justify economic liberties in
terms of egalitarian liberalism. Neoclassical liberalism emphasizes
social justice and argues for the efficient achievement of social
justice through market forces. However, it suffers some problems
that, if thick economic liberties are accepted as basic liberties,
the difference principle is not necessarily satisfied since social
security systems and social safety net programs are limited, and
neoclassical liberalism is reduced to the efficiency argument.
Nevertheless, we believe that economic liberties and social justice
might be successfully integrated if economic liberties are
identified with the moral power of responsible self-authorship
thus the scope of economic liberties is newly interpreted.

- Welfare Change in Relation to the Percentile
Income Distribution in Japan between
1982 and 2013
Seong Ha Hong, Young Kook Woo
This paper investigates whether welfare improved in each
income percentile in Japan during 1982 and 2013. By dividing
total consumption expenditure into food and non-food categories,
we consider welfare as increased if the amount of total
consumption expenditure of the previous year falls within the
budget constraint line of current year and vice versa. According to
about thirty years¡¯ data, the time between 1982 and 1992 is the
decade of improved welfare while in the next decade between
1993 and 2001 welfare deteriorated. The final decade can be
characterized as a mixed period. We find that welfare change is
not correlated with income level. Almost all worse-off(better-off)
deciles have the smallest(biggest) among the rate of change in
nominal consumption expenditure, those of food prices, and
non-food prices.

- This paper investigates whether fixed and mobile broadband
services are substitutes or complements using firm-level panel
data obtained from three major telecommunications operators in
South Korea. We employ a multi-level demand model based on
Hausman et al. (1994), which allows for the possibility of
complementarity between differentiated services. The estimated
price elasticities of demand indicate that mobile broadband is a
(weak) substitute for fixed broadband while fixed broadband is
complementary to mobile broadband. This is in contrast with the
previous studies based on logit models which essentially assume
substitution between different technologies. This result implies
that fixed and mobile internet services constitute distinctive
antitrust markets at least in the early stage of mobile broadband
development.
