gThe
effects of cross-regional free trade agreements under a vertical industry
structureh
Journal
of International Trade & Economic Development
This paper
examines the effects of a cross-regional free trade agreement (FTA) on tariffs,
welfare, and the incentives for multilateral free trade in a three-country
model with a vertical industry structure. We show that the FTA induces member
countries to reduce their tariffs on nonmember countries. On the other hand, a
nonmember country lowers its tariff on final-good imports, but raises its
tariff on intermediate-good imports. Also, the FTA makes member and nonmember
countries better off. After the FTA is enacted, member and nonmember countries
have an incentive to support multilateral free trade, so an FTA acts as a
building block for multilateral trade liberalization.

gEconomic
Stability and Interest-Rate Controls in an Open-Economy Model with Productive
Moneyh
Economics
Bulletin, Vol. 32 No. 4
pp. 3053-3060
We analyze the
relation between interest-rate controls and equilibrium determinacy in a
two-country model in which money is employed as a factor of production. Given
this specification, holding cash generates an opportunity cost. Therefore,
equilibrium can be indeterminate even if both countries demonstrate
additive-separable utilities between consumption and non-productive money.

gAn Optimal Government Spending Reversal Rule in a Small Open Economyh
International Review of Economics and
Finance
This
paper presents a reexamination of debt stabilization policy in a small open
economy borrowing from abroad. Spending reversals are incorporated as a policy
option available to policy-makers for stabilizing public debt. Results show
that a spending reversal rule can be welfare-improving and that there exists an
optimal degree of spending reversal. An optimal spending reversal rule can
lower both the tax rate volatility and interest rate volatility compared with
the case without the reversal rule. Results also suggest that, as friction in
foreign borrowing becomes greater (because of a higher country-specific
interest rate premium), the welfare benefit of the reversal rule will be
increasingly important.

gReexamination
of Strategic Public Policiesh
Japanese Economic Review
This paper
attempts to reinterpret the familiar approach to strategic public policies from
the viewpoint of inefficiencies involved in oligopoly where firms engage in Cournot competition. To this end, we introduce tools called
"quasi-reaction functions" and "quasi-supply curves". These
tools allow us to conduct analyses by using the standard partial equilibrium
diagram, i.e., the quantity-price plane. We can directly find the relationship
between prices and quantities and hence easily deal with inefficiencies and
policies to correct them. We specifically reexamine public policies related to
mixed-oligopoly, excess entry, technology choices with free entry and exit, and
foreign oligopoly.

gTrade and Global Pollution in Dynamic Oligopoly with Corporate
Environmentalismh
Review
of International Economics
This paper examines the effects of international trade in the presence of
dynamic oligopolistic competition where the stock of global pollution has a
negative welfare effect and the oligopolists'
objectives may include society's pollution damage as well as private profits.
In a symmetric case where the number of firms, emission coefficient, and firms'
environmental consciousness are the same in two countries, an opening of trade
unambiguously improves each country's welfare in the short run. In the long
run, however, trade increases the stock of global pollution and hence, whether
opening of trade is beneficial depends on the parameters of the economy. If
there are asymmetries between countries, the short-run gains from trade in both
countries are not necessarily guaranteed, because trade liberalization may
increase output in one country and reduce it in the other. Moreover, free trade
may result in lower pollution stock than under autarky.

gFree Trade Agreement and Vertical Trade with a Manufacturing Baseh
Review of International Economics
We examine the effects of free trade agreement (FTA) on tariffs and welfare in
a three-country model with vertical trade, where an FTA is formed between a
country exporting a final good whose production involves using an intermediate
good, and a country exporting the intermediate good in exchange for the final
good. We demonstrate that the FTA reduces its member country's external tariff,
whereas it raises the non-member country's tariff. The non-member country
unambiguously becomes better off. In contrast, the FTA may or may not make its
member countries better off. This implies that the formation of an FTA may not
always be Pareto-improving.

gErgodic Chaos and Aggregate Stability: A Deterministic
Discrete-Choice Model of Wealth Distribution Dynamicsh
International Journal of Economic Theory
This
paper studies wealth distribution dynamics in a small open economy with a continuum
of consumers indexed by initial wealth. Each of them solves a discrete-choice
problem whose optimal policy function exhibits ergodic
chaos. We show that for any initial distribution of wealth given by a density,
the wealth distribution converges to a unique invariant distribution, and
aggregate wealth converges to the corresponding value. Thus ergodic
chaos leads to aggregate stability rather than instability. These results are
illustrated with various numerical examples.

gCost-reducing
R&D investment, Labor market, and Tradeh
Review of
International Economics
(2012 20:821-827)
This paper
constructs a two-country model in which oligopolistic firms export goods and
undertake cost-reducing R&D investment. Each country imposes tariffs. A
decrease in the tariff rates in both countries decreases cost-reducing R&D
investment.

gDynamic
analysis of location choice by multinational firmsh
Journal of
Macroeconomics
This paper
constructs a North–South endogenous growth model to investigate how the
organizational forms of final goods firms evolve. Initially, the final goods
firms in the North obtain intermediate goods from Northern firms and produce in
the North. When trade costs are sufficiently low, as the economy develops, the
final goods firms produce the final goods in the North and obtain the
intermediate goods from Southern firms. As the economy develops further, they
produce the final goods in the South and obtain intermediate goods from
Southern firms.

gEnvironmental Management Policy under
International Carbon Leakageh
International Economic Review
This paper studies environmental
management policy when two fossil-fuel-consuming countries non-cooperatively
regulate greenhouse-gas emissions through emission taxes or quotas. The
presence of carbon leakage caused by fuel-price changes affects the tax-quota
equivalence. We explore each country's incentive to choose a policy instrument
in a two-stage policy choice game and find subgame-perfect
Nash equilibria. This sheds new light on the questions of which policy
instrument is more stringent and of why adopted instruments could be different
among countries. In particular, our result suggests a reason why developing
countries tend to employ emission taxes, while developed countries tend to
adopt emission quotas.

gAid for trade, infrastructure, and growthh
International Tax and Public Finance
Aid
for trade is a new foreign aid initiative to assist recipient countries to
build trade-related infrastructure. We formulate a small-country, two-good
(i.e., investment and consumption goods), two-factor
(i.e., capital and labor) endogenous growth model with learning by doing and intersectoral knowledge spillovers, where the import
transport cost depends inversely on public infrastructure. Focusing on the case
where the country is incompletely specialized and imports the investment good,
we show that a permanent increase in the recipient's aid/GDP ratio raises the
steady-state growth rate if and only if the investment good is more
labor-intensive.

gFootloose Capital and Comparative Advantageh
Pacific Economic Review
We investigate the effect of country size
differentials and Ricardian technology differences on
firmsf location decisions using a two-country, two-good (homogeneous
agricultural good and differentiated manufacturing products), two-factor (labor
and footloose capital) simple New Economic Geography (NEG) model. We found that
manufacturing firms may agglomerate in a country where the manufacturing sector
has a comparative disadvantage. Additionally, when country
size differentials and Ricardian technology
differences exist between two countries, the key factor influencing firmsf
location decisions changes according to the level of trade liberalization, from
being market size-dependent to becoming technology-dependent.

gPoverty traps and inferior goods in a dynamic Heckscher–Ohlin modelh
Macroeconomic Dynamics
We extend the dynamic Heckscher–Ohlin
model in Bond et al. [Economic Theory(48, 171–204, 2011)] and show that if the labor-intensive
good is inferior, then there may exist multiple steady states in autarky and poverty
traps can arise. Poverty traps for the world economy, in the form of
Pareto-dominated steady states, are also shown to exist. We show that the
opening of trade can have the effect of pulling the initially poorer country
out of a poverty trap, with both countries having steady state capital stocks
exceeding the autarky level. However, trade can also pull an initially richer
country into a poverty trap. These possibilities are a sharp contrast with
dynamic Heckscher–Ohlin models with normality in consumption,
where the country with the larger (smaller) capital stock than the other will
reach a steady state where the level of welfare is higher (lower) than in the
autarkic steady state.

gThe
dynamic Heckscher–Ohlin model: A diagrammatic
analysish
International
Journal of Economic Theory
In this paper, we show that the main results of
dynamic Heckscher–Ohlin models (with non-homothetic
preferences) can be derived from diagrams which represent the basic functions
in static models such as the Rybczynski line, income
expansion paths, and excess demand functions at steady states. Results include
not only the existence and the multiplicity of steady states in autarky and
under free trade, but also their stabilities and the static and dynamic Heckscher–Ohlin theorems.

gConsumption Externalities and Equilibrium Dynamics with Heterogenous
Agentsh
Mathematical Social Sciences
This
paper explores the effect of consumption externalities on equilibrium dynamics
of a standard neoclassical growth model in which there are two types of agents.
To emphasize the presence of heterogenous agents, we
distinguish intergroup consumption externalities from intragroup consumption
externalities. We show that if the intragroup externalities dominate the
intragroup external effects, then the steady state equilibrium satisfies
saddle-point stability and the equilibrium path of the economy is uniquely
determined. In contrast, if the intergroup external effects of consumption are
strong enough, the steady state equilibrium is either unstable or locally
indeterminate. Using analytical as well as numerical considerations, we present
intuitive implications of stability conditions.

gPatentability and Knowledge Spillovers of Basic R&Dh
Southern Economic Journal
This
study develops an R&D-based growth model with basic and applied research to
analyze the growth and welfare effects of two patent instruments: (a) the
patentability of basic R&D, and (b) the division of profit between basic
and applied researchers. We find that for the purpose of stimulating basic
R&D and economic growth simultaneously, increasing the share of profit
assigned to basic researchers is more effective than raising the patentability
of basic R&D, which has either a negative effect or an inverted-U effect on
technological progress. However, a benevolent patent authority requires both
patent instruments to achieve the socially optimal allocation in the
decentralized economy.

gStructural Change in Current Account and Real Exchange Rate Dynamics: Evidence
from the G7 Countriesh
Pacific Economic Review
Lee
and Chinn (2006) and Chinn and Lee (2009) decomposed current account and real
exchange rate into temporary and permanent shocks and argued that a temporary
shock creates the combination of a current account surplus (deficit) and real
exchange rate depreciation (appreciation). This paper extends their framework by
examining a possible structural break in current account and real exchange rate
dynamics. Using G7 country data for 1980--2007, we find structural changes in
two-variable dynamics for all G7 countries during the 1990s. Temporary shocks
have not been the main source of fluctuation in the current account since the
1990s. Our empirical results imply that the conventional mechanism has played a
limited role in explaining the dynamics of the two variables.

gA
note on the endogenous timing of tariff policy in the presence of a time lag
between production and trade decisionsh
Open
Economies Review
Using the
Hamilton–Slutsky extended endogenous timing game
of observable delay framework, we analyze the endogenous timing of
tariff policy in the presence of a time lag between production and trade
decisions. In particular, focusing on the strategic relationships between an
importing countryfs government and an exporting monopoly firm, we show that a
natural Stackelberg situation exists in which the
importing countryfs government as first mover determines the tariff rate and
the exporting monopoly firm as second mover determines the production level. We
also find that the natural Stackelberg equilibrium is
Pareto superior to both the Nash and alternative Stackelberg
equilibria. This implies that commitment to an ex ante optimal
tariff policy before the production decision is made is optimal for the
affected parties.

gOptimal fiscal
policy with social status and productive government expenditureh
Economics Bulletin
We examine the
optimal tax rule in an endogenous growth model with public capital and wealth-enhanced
social status. When government expenditure is productive, the equality of
marginal productivities of private and public capital holds. Wealth-induced
preference can violate this equality, since the marginal utility from private
capital is also a value of private capital. We obtain the optimal fiscal policy
in which the positive income tax rate is higher than the subsidy rate for
saving but is lower than the tax rate in the case without social-status
preference.

gHistory-Dependent Paths and Trade Gains in a Small Open Economy with a Public
Intermediate Goodh
International Economic Review
This
study reexamines McMillan's (International Economic Review 19 (1978), 665-78)
analysis of a dynamic small open economy with a public intermediate good.
Concerning the trade patterns of the open economy, we find results that were
overlooked in McMillan's analysis. Among others, if labor endowment is of
intermediate size, there are two saddle-point steady states, and the initial
stock of the public good determines the long-run trade pattern. We also add a
gains-from-trade analysis to McMillan's model and demonstrate that if the
economy has a comparative advantage in a good with productivity less sensitive
to the public intermediate good, the economy may lose from trade at the steady
state.

gTrade
liberalization, economic growth, and income distribution in a multiple-cone
neoclassical growth modelh
Oxford Economic Papers
The empirical
literature on trade liberalization reflects two puzzles. First, the effect of
trade liberalization on economic growth is ambiguous. Second, the effect of
trade liberalization by developing countries on their income distribution is
ambiguous. This paper attempts to explain simultaneously these two puzzles,
based on a multiple-cone neoclassical growth model. The model shows that
countries that are labour abundant in a global sense
may see a rise in income inequality and a fall in per capita gross domestic
product with liberalization if they are capital abundant in a local sense. The
results suggest that the existence of multiple cones and the multiple steady
states within the same cone, or the existence of global and local factor
abundances, can be a possible explanation of these puzzles.

gStrategic Foreign Direct Investment in Vertically Related Marketsh
Economic Record
By
using a simple North-South trade model with vertically related markets, this
paper draws our attention to previously unidentified effects of foreign direct
investment (FDI), namely that a North downstream firm affects the pricing
behavior of an input supplier through technology spillovers and market
integration led by FDI. Whether the North firm strategically undertakes FDI in
the presence of technology spillovers depends on South firm's capacity to
absorb North's technology. When the capacity is not very high, the North firm
could actually gain from technology spillovers to the South firm. FDI may
benefit all producers and consumers.
