"Price undertakings, VERs, and foreign direct investment - The case of foreign
rivalry"
Canadian Journal of Economics
Antidumping (AD) petitions are often
withdrawn in favor of VERs and price
undertakings. This paper compares the three options in the presence of
protection-jumping foreign direct investment (FDI), with special emphasis
on rivalry between foreign firms. We show that a VER is less likely to
induce FDI than a price undertaking or AD. As a result, by settling AD
cases with VER agreements, the importing country can pursue a more
protectionist policy without triggering FDI. This result may explain the
1994 GATT ban on VERs following the proliferation of
AD use.

"The Home Market Effect and Trade Costs"
Japanese Economic Review
<zeng@gsm.kagawa-u.ac.jp>
Concerning industrial location, the home market effect
(HME) predicts that a
large country is a net exporter of industrial goods. Recent literature shows
that high
transport costs in the traditional sector may obscure the HME in an early model
of
two sectors `a la Helpman and Krugman.
This paper presents an alternative model
that displays the relationship between the HME and arbitrary transport costs
while
allowing for the derivation of analytical results by simple algebra. Our
results show
that the transport costs in the traditional sector do not obscure the HME but
constitute a dispersion force decreasing the impact of the HME.

"Competing Communications Networks and International Trade"
Journal of Economic Integration
<047d257e@stu.kobe-u.ac.jp>
This paper investigates the effects of competing communication networks on
trade patterns in a Chamberlinian-Ricardian model of
monopolistically competitive
firms with a continuum of industries that require communication services
in production. We conclude that intraindustry trade
between different
networks is determined by the relative size of networks and technological
differences,
and that a network will not have incentive to expand indefinitely,
despite network externalities.

"Strategic Divisionalization, Product
Differentiation and International Competition"
Journal of the Korean Economy
<kikuchi@econ.kobe-u.ac.jp>
In this note we construct a simple international
differentiated duopoly model that
involves a divisionalization decision. It will
be shown that the number of third market
divisions of a parent firm with a cost advantage is relatively large. The
results imply
that the cost competitiveness of one country’s firm will be magnified
through
divisionalization decisions.

"A Variety Expansion Model of Growth with External Habit Formation"
Journal of Economic Dynamics and Control
<mino@econ.osaka-u.ac.jp>
This paper introduces consumption externalities into one of the base line
models of growth in which continuing expansion of product variety sustains long-term growth.
We assume that consumers set a benchmark stock of consumption for each good so that there
are commodity specific external effects. Each good is produced by a monopolistically
competitive firm and the film exploits the presence of consumption external effects in
determining its profit-maximizing price. Given those settings, we show that the introduction
of consumption externalities may affect the balanced-growth characterization, transitional
dynamics and policy effects in fundamental manners.

"Generalized Taylor Rule and Determinacy of Growth Equilibrium"
Economics Bulletin
<mino@econ.osaka-u.ac.jp>
This paper re-examines equilibrium determinacy under the interest-rate
control rules in a simple model of endogenous growth. We use a standard
money-in-the-utility formulation with fixed labor supply and an Ak technology
under which the balanced-growth path is unique and money is superneutral
in the long run. We show that even in such an environment the interest-rate
feedback rule a la Taylor may produce indeterminacy of equilibrium if the
monetary authority adjusts the nominal interest rate in response to the growth rate
of real income as well as to the rate of inflation.

"Subsidies and Countervailing Duties
with Firm Heterogeneity"
Asia-Pacific
Journal of Accounting and Economics
The WTO allows importing countries to impose
countervailing duties (CVDs)
when subsidies provided in exporting countries
cause serious injuries.
This paper examines the effects of CVDs as well as those of subsidies.
Using an international oligopoly model, we
specifically explore direct
export subsidies and capital subsidies in the
presence of heterogeneity
among recipients. All recipient firms gain from
export subsidies, but this
may not be the case for capital subsidies. The
maximum CVD allowed under
the WTO rules may be more than enough to offset
the injury caused by a
capital subsidy.

"Environmental Protection and Trade Liberalization in a Small Open Dual
Economy"
Review of Development Economics
<idaito@intcul.tohoku.ac.jp>
We investigate when environmental protection and trade liberalization may
improve urban unemployment and welfare in a small open Harris-Todaro model
with polluting urban manufacture. While a tariff reduction decreases
manufacturing employment, a higher pollution tax may increase it when a
dirty input is complementary to capital. Environmental protection reduces
the level of urban unemployment under the same condition as trade
liberalization. Trade liberalization will mitigate a decrease in GDP due to
environmental protection if the degree of urbanization is low and if rural
technology exhibits weak diminishing returns to labor. This GDP effect plays
a central role in welfare improvement.

"Trade Theorems in a Model of Vertical Production Chain"
International
Review of Economics & Finance
< mayan003@kobe-u.ac.jp>
This
paper investigates the Rybczynski theorem, the Stolper-Samuelson theorem, and
the Heckscher-Ohlin
theorem in a two-factor vertical production chain model of trade.
For this purpose,
capital is introduced into the model of Yano and Dei (2003). A primary
analytic device is the economy-wide production curve.
This curve is derived under autarky
and free trade, respectively.

"Indirect Network Effects and Trade
Patterns"
Economics
Bulletin
<kikuchi@econ.kobe-u.ac.jp>
Indirect network effects exist when the
utility of consumers is
increasing in the variety of complementary products
available for use with
an electronic hardware device. In this note,
we examine how indirect
network effects work as a determinant of trade
patterns. For these purposes
we construct a simple two-country model of
trade with incompatible
country-specific hardware technologies. We show that trade
patterns are
determined by the interaction between hardware
differentiation and indirect
network effects due to software availability.

“Indeterminacy in a Two-Sector Endogenous
Growth Model with Productive Government
Spending”
Journal of
Macroeconomics
<hu@econ.kobe-u.ac.jp>
We construct a two-sector endogenous
growth model in which productive
government
spending is essential for sustaining an economy's long-run growth. It
is
shown that, like the original one-sector Barro (1990)
model, the
balanced
growth path (BGP) equilibrium is unique under some conditions. Unlike
Barro
(1990), however, our two-sector framework exhibits transitional
dynamics.
In fact, when the intertemporal elasticity of
substitution for
consumption
is large, around the BGP equilibrium, there is a continuum of equilibrium
paths
whose growth rates commonly converge to a balanced growth rate. That
is,
the BGP equilibrium is indeterminate.

“Location Choice, Competition, and Welfare in Non-Tradable Service FDI”
International
Review of Economics & Finance
<hkurata@fc.ritsumei.ac.jp>
We investigate whether non-tradable
service FDI is efficient from a welfare point of view. A fixed number of firms
strategically decide which markets to locate in and then compete in quasi-Cournot fashion. Considering firm location in two symmetric
markets, non-tradable service FDI may or may not be efficient for the source
country, depending on the total number of firms, competition in markets and the
curvature of the demand function. In contrast, non-tradable service FDI is
always efficient for the host country and the overall economy. This implies
that any policy that affects firm location between two symmetric markets will
not be beneficial from a welfare viewpoint.

"Foreign equity caps under two types of competition: Bertrand and Cournot"
Economics Bulletin
<hkurata@fc.ritsumei.ac.jp>
This paper explores foreign equity caps
for international joint ventures under different types of competition, i.e.,
Bertrand and Cournot competition, with product
differentiation. We demonstrate that government sets the foreign equity cap at
a laxer level under Cournot competition than under
Bertrand competition. This result illustrates that the possibility of international
joint ventures weakens government's ability to affect firm behavior through the
implementation of foreign equity caps.

"Network Externalities and Comparative
Advantage"
Bulletin

<kikuchi@econ.kobe-u.ac.jp>
In this article I examine how the network
externalities of communications
activities and trading opportunities interact to
determine the
structure of comparative advantage. These
interactions are examined
by constructing a two-country, three-sector
model of trade involving
a country-specific communications network
sector. The role of the
connectivity of network providers, which allows users of
a network to
communicate with users of another network, is also explored

This paper considers a two-period model of
market entry with horizontally
differentiated products and switching costs. Conditions
that are conducive
to a competitive environment in the second
period are shown to yield a less
competitive outcome in the first period. That is, when
the marginal cost of
a foreign entrant is relatively low, the
first-period output of a domestic
monopolist is relatively low as well.

"Time Zones, Outsourcing and Patterns
of International Trade"
Economics
Bulletin
<kikuchi@econ.kobe-u.ac.jp>
This paper proposes a three-country model of
business services trade that
captures the role of time zones in the division of
labor. The connectivity
of business service sectors via communications
networks (e.g., the
Internet) is found to determine the
structure of comparative advantage.
That is, two countries with connected
service sectors have a comparative
advantage in the good that requires business
services. It is also shown
that the third country inevitably specializes in
the good that does not
require business services.

"Foreign Direct
Investment and China's Bilateral Intra-Industry Trade with Japan and the
US."
Journal of Asian
Economics
<xing@iuj.ac.jp>
This paper analyzes the dynamic
changes of China 's intra-industry trade with its
major trading partners, Japan and the US , from 1980 to 2004. The estimated
intra-industry indexes demonstrate that, while shares of China's intra-industry
trade with both Japan and U.S rose substantially, its intra-industry trade with
Japan increased to 34 per cent of the overall trade in 2004, considerably
larger than 10 per cent with the US. The Sino-Japanese intra-industry trade
concentrated in electrical and machinery sectors and accounted for 52 per cent
and 46 per cent of the total trade in those sectors respectively. On the other
hand, it is in chemical and food sectors where intra-industry trade represented
a relatively large proportion of Sino-US trade. In addition, the paper
investigates to what extent that foreign direct investment from those two
countries promoted their bilateral intra-industry trade with China
. The empirical results show that, Japanese direct investment performed
a significant role in enhancing the bilateral intra-industry trade. However, it
finds no evidence that the US direct investment contributed to the growth of
the Sino-US intra-industry trade.

"Foreign Outsourcing, Exporting, and
FDI: A Productivity Comparison at the Firm Level"
Journal
of International Economics
<tomiura@ynu.ac.jp>
This paper documents how productivity varies
with globalization modes,
based on a firm-level data set covering all
manufacturing industries in Japan.
Foreign outsourcers and exporters tend to be
less productive than the firms
active in FDI or in multiple globalization modes,
but more productive than
domestic firms. This productivity ordering is robust
even when firm size,
factor intensity and/or industry are controlled
for.

“A Decomposition of Gains from Trade in a
Differentiated Oligopoly”

<kenjifujiwara@kwansei.ac.jp>
Constructing a two-country oligopolistic model with product differentiation,
this paper revisits welfare effects of free
trade. The hybrid of procompetitive
and variety expansion effects means that trade
liberalization has definite benefits
for the consumer, while it is contingent
whether it is beneficial to oligopolistic firms
and national welfare. We illustrate how these
two effects interactively affect
the possibility of gains from trade with simple
diagrams.

"Growth and Bubbles with Consumption
Externalities"
Japanese
Economic Review
<mino@econ.osaka-u.ac.jp>
This paper explores the role of consumption externalities in an overlapping
generations economy with capital accumulation. If consumers in each generation
are concerned with other agents' consumption behaviors, there exist intergenerational
as well as intragenerational consumption externalities. It is the presence of
intergenreational consumption externalities that may produce fundamental effects
both on equilibrium dynamics and on steady-state characterization of the economy.
This paper demonstrates this fact in the context of a simple model of endogenously
growing, overlapping-generations economy with or without asset bubbles.

This paper reports a seemingly surprising
property of nonlinear
feedback Nash strategy in a differential game with
no state variable in the
payoff of each player. While the open-loop Nash
and linear feedback Nash
equilibria coincide with the static Cournot-Nash equilibrium, i.e., they
depend neither on time nor the state variable over
time, the nonlinear feedback
strategy can be properly defined and it approximates
the bilateral
collusion as proved by Tsutsui

“Partial Privatization in a Differentiated Mixed Oligopoly”
Journal
of Economics
<kenjifujiwara@kwansei.ac.jp>
A model of differentiated mixed oligopoly is
developed to
systematically discuss the welfare consequences of partial
privatization of a
public firm. We analytically derive the optimal
degree of partial privatization
not only in the short-run with restricted entry
but also in the long-run
with free entry. It is shown that the short-run
optimal policy is
non-monotonic in the degree of love of variety, while the
optimal degree of
privatization is monotonically increasing in the
consumer's preference for variety in
the long-run.

<odams@mta.biglobe.ne.jp>
This
paper develops a three-sector, three-factor specific factor model with a tariff
and presents conditions
under which capital imports and tariffs can be
welfare enhancing in a developing country. The impact on
welfare depends on the tariff revenue effect and the
repatriation effect. A capital import is welfare enhancing
if it reduces the domestic output of imports. A
tariff is welfare enhancing only if it reduces the return to foreign capital.

We evaluate whether the Renminbi (RMB) is misaligned, relying upon conventional statistical methods of inference.
A framework built around the relationship between relative price and relative output levels is used. We find that,
once sampling uncertainty and serial correlation are accounted for, there is little statistical evidence that the RMB is
undervalued, even though the point estimates usually indicate economically significant misalignment. The result is
robust to various choices of country samples and sample periods, as well as to the inclusion of control variables.

“Child Labor and
Globalization”
Journal of Labor Economics
<zhao@rieb.kobe-u.ac.jp>
The paper embeds child labor in a standard two-sector general-equilibrium model
of a small open economy facing perfectly competitive markets, efficiency wages,
and free-trade. The modern sector produces a homogeneous good using skilled
adult labor and capital, and offers effort-based efficiency wages. The agrarian
(traditional) sector produces a homogeneous good using unskilled (child and
adult) labor and skilled adult labor, and offers nutritional efficiency wages
to child workers. Nutritional efficiency wages
introduce wage stickiness and transform the economy into a dual one with
unlimited supply of child labor. Trade policies that increase the output of the
modern sector reduce the incidence of child labor and the dispersion of wages
between adult skilled workers and unskilled workers. Emigration of skilled
adult workers reduces the incidence of child labor, whereas emigration of
unskilled adult workers has the opposite effect. Domestic subsidies that reduce
the child wage increase the incidence of child labor; and a ban on child-labor
benefits unskilled adult workers but hurts skilled adult workers.

"A Note on Strategic Trade Policy and Endogenous Quality Choice"
Review of International Economics
<jinji “at” e.okayama-u.ac.jp>
This paper shows that some of the main policy
implications in Park (2001) and Zhou, Spencer, and Vertinsky
(2002) are sensitive to their assumptions on marginal production costs.
The unilaterally optimal policy for investment towards quality improvement is
analyzed, assuming constant and non-negative marginal production costs under
vertically differentiated international duopoly. If marginal production
costs are different across firms, the optimal policy for each exporting country
may be opposite in its sign from that shown by the existing papers under
Bertrand competition. The policy reversal may also occur for the low
quality exporting country under Cournot competition.

"A
Monopolistic Competition Model of International Trade with External Economies
of Scale"
North American
Journal of Economics and Finance
<suga@econ.hokudai.ac.jp>
This paper presents a two-country model of monopolistic competition in which differentiated products are produced subject to external economies of scale and two countries differ only in size measured by the factor endowment. It is shown that under free trade, the larger country has positive net exports of differentiated products, which leads to its gains from trade, while the smaller county may lose from trade. Noteworthy is that the industrial agglomeration induced by the inter-industry trade is possibly harmful to both countries if the two countries are similar in size and the taste for product diversity is sufficiently strong.
