International Trade with a Public Intermediate Good and the Gains from Trade*

This paper presents a one‐primary factor, two‐consumer good, and two‐country model of international trade where each country’s government supplies a country‐specific public intermediate good so as to attain efficient production. By introducing the Marshallian adjustment process, it is demonstrated that the country with larger factor endowment exports the good whose productivity is more sensitive to the public intermediate good. Our normative analysis of free trade shows the following results. First, at least one country gains from trade. Secondly, if a country incompletely specializes in the trading equilibrium, the country necessarily loses from trade.     

A Factor Endowment Theory of Endogenous Growth and International Trade

This paper presents a dynamic general equilibrium model of multi‐country, two‐good and two‐factor, in which both long‐run growth and international trade patterns are examined. In each country, government expenditure on a public intermediate good plays a crucial role in the realization of persistent growth. It is shown that the long‐run pattern of international trade is determined in a Heckscher‐Ohlin manner.     

International trade and directed search unemployment in general equilibrium

We develop an open economy general equilibrium model, with auction‐based directed search unemployment, to study the interactions of trade and unemployment. The theory ascribes all outcomes purely to the fundamentals of technology and endowment. If countries differ by endowment, trade makes both the unemployment rate and the rental in the capital‐(labour‐) abundant country rise (decline) but does not lead to equalization. If, alternatively, countries differ by technology, trade increases (decreases) the unemployment rate in the country whose technology is relatively superior (inferior) for producing the capital‐intensive good.     

ENDOGENOUS FLUCTUATIONS IN TWO‐COUNTRY MODELS*

This paper investigates the interlinkage in the business cycles of large‐country economies in a free‐trade equilibrium. We consider a two‐country, two‐good, two‐factor general equilibrium model with Cobb‐Douglas technologies and linear preferences. We also assume decreasing returns to scale in the consumption good sector. We first identify the determinants of each country's global accumulation pattern in autarky equilibrium, and secondly we show how a country's business cycles may spread throughout the world once trade opens. We thus give capital intensity conditions for local and global stability of competitive equilibrium paths.     

HISTORY‐DEPENDENT PATHS AND TRADE GAINS IN A SMALL OPEN ECONOMY WITH A PUBLIC INTERMEDIATE GOOD*

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.     

Oligopsony Distortions and Welfare Implications of Trade*

While imperfect competition in the output market has garnered extensive focus in the new trade theory literature, input market imperfection has received considerably less attention. Since market power in input purchase has been growing in recent years, it is worth examining the welfare implications of trade arising from oligopsony power. We develop a model consisting of two final goods, one intermediate good, and two primary factors (capital and labor). One final good and the intermediate good employ primary factors, whereas the other final good uses labor and the intermediate input. All markets operate under perfect competition except for the intermediate input, which is oligopsonistic. Using this model, we show that oligopsony can lead to some anomalies such as an increase in the oligopsony output, reward to the intensive‐factor in the oligopsony sector, national welfare, and deterioration of terms of trade, but it always decreases the reward to the intermediate input.     

International Trade and Volume Patterns under Quasilinear Preferences

We formally analyze the pattern and volume of trade by embedding quasilinear preferences in the standard perfectly competitive, two‐factor, two‐good, two‐country trade model. Quasilinear preferences deliver a natural partition of the two goods into a luxury and a necessity, and preserve the validity of the Heckscher–Ohlin and Heckscher–Ohlin–Vanek theorems. In addition, the predicted factor content of trade under quasilinear preferences is smaller (larger) than the predicted factor content of trade under homothetic preferences if and only if the luxury good is capital (labor) intensive. This result offers a novel explanation for the “missing‐trade” mystery.     

Public infrastructure and trade in a dynamic two‐country model

We develop a two‐country dynamic trade model with public infrastructure having an “unpaid‐factor”‐type positive externality on private sectors’ productivity. With welfare‐maximizing national governments making infrastructure investment, we show that a country with a smaller labor endowment, a lower depreciation rate of infrastructure, and/or a lower time preference rate will become an exporter of a good that is more dependent on infrastructure and will gain from trade, whereas its trading partner may lose from trade. We consider both the nonstrategic governments case and the case of strategic governments that recognize the effect on the terms of trade.     

Aid,non‐traded goods,and growth

Abstract We examine the effects of foreign aid in a small recipient country with two traded goods, one non‐traded good, and two factors. Learning by doing and intersectoral knowledge spillovers contribute to endogenous growth. We obtain two main results. First, a permanent increase in untied aid raises (or lowers) the growth rate if and only if the non‐traded good is more capital intensive (or effective labour intensive) than the operating traded good. Second, a permanent increase in untied aid raises welfare if the non‐traded good is more capital intensive than the operating traded good; otherwise, it may raise or lower welfare.     

Free Trade Agreement and Vertical Trade with a Manufacturing Base

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.     

A Trade Model of Intermediate Products With Transportation Cost

This paper presents a trade model of intermediate products where a country has the same production technology as the outside world, and the source of trade is the unbalance in the factor endowment. The decision as to how much to process the raw material before exporting depends on the capital requirements for the processing, and the change in transportation cost due to the processing. The lower the requirements of capital coupled with a more rapid fall in the transportation cost in the earlier stage of production, the more probable that the country will export the processed intermediate good instead of the raw material.     

The Distributional and Allocative Impacts of Virtual Labor Mobility across Time Zones through Communication Networks

Using a specific‐factors' model, with two goods (a shift‐working good and a non‐shift‐working good), three factors (capital specific to shift‐working, land specific to non‐shift‐working and labor) and two countries (Home and Foreign), which are located in different time zones, we highlight the impact of trade in labor services via communication networks on factor prices and production patterns. If two countries are identical in size, then under free trade in labor services, all workers work only in their local daytime, and night shift in each country is performed by imported labor services supplied by residents of the other country in their local daytime. Night‐time wage becomes the same as daytime wage (a wage equalization result). Other factor prices are also equalized. In both countries, capital rental rate increases, while land rent decreases. However, if two countries are different in size, trade in labor services does not equalize wages: in the large country, wages for night‐shift workers are higher than daytime wages and some residents work at night; in the small country, daytime wages become higher than night‐time wages and no one works at night, and night‐shift work is done by imported labor services from the large country. Land rent in the small country decreases. Land rent in the large country may or may not decrease, but it is always higher than in the small country. Capital rental rates in both countries are equalized and increase.     

Public infrastructure for production and international trade in a small open economy: a dynamic analysis

This paper develops a dynamic trade model with a stock of public infrastructure, which has a property of “unpaid factor of production”. We show that a country with a smaller (larger) labor endowment tends to become an exporter of a good whose productivity is more (less) sensitive to the stock of public infrastructure. We also show that after the opening of trade, the labor-scarce country becomes unambiguously better off but the labor-abundant country may become worse off. Overall, these results contrasts with those obtained in the case of public intermediate goods with a “creation of atmosphere” property.     

The trade balance and the terms of trade in a two-country two-sector OLG economy

We consider a two-country, two-sector OLG model. It is shown that the trade balance and the relative price of exports are always positively related when exports are labor intensive regardless of the elasticity of intertemporal substitution in consumption. A large response of savings to future prices becomes a sufficient condition for an inverse relation between these variables only if exports are capital intensive. In this case, a rise in the terms of trade can be followed by a trade balance decline if consumption goods are capital intensive and the income effect implied on savings is negative and large.     

Trade Liberalization,Skill‐linked Intermediate Production and the Two‐sided Wage Gap

Abstract

A rising wage‐gap, almost universally, in the last two decades has contradicted the age‐old conventional wisdom of asymmetric wage movements across nations when trade is liberalized. We offer an explanation that fits well with the emerging trade pattern between the developed and more advanced developing countries like India and Mexico. We argue that a tariff reduction in the South on imports of an intermediate good from the North may raise the wage‐gap in both the North and the South. The price of the intermediate good moving in different directions and different factor‐intensity‐ranking of this good relative to the two different final goods produced in the two countries underlie this result. Rising wage inequality may specially affect the South because educational expenses and infrastructure do not allow ready transformation of the vast masses of unskilled workers into skilled workers. Hence, the policy lesson of the paper seems to be more public effort in arranging for smoother acquisition of human capital by the unskilled.     

Status-Seeking, Catching-Up, and Comparative Statics in a Dynamic Heckscher–Ohlin Model

This paper examines a two‐country dynamic general equilibrium model with status‐seeking agents. We show that the introduction of status‐seeking behavior brings about new properties in equilibrium dynamics. While there exists a continuum of steady states in the standard dynamic models, the present framework demonstrates that, under some conditions, there uniquely exists an incompletely specialized steady state, which is locally saddle‐point stable. Therefore, catching‐up and overtaking phenomena seen in economic development can be explained, and comparative statics analysis also is made possible. Our comparative statics analysis illustrates, for example, that trade pattern is determined in the Heckscher–Ohlin manner; the patient country acts just like a capital abundant one to export the capital‐intensive good. Furthermore, as distinct from the existing literature, the present study shows that the existence of an incompletely specialized steady state can be ensured even if the two countries conduct different policies.     

Intra‐industry Trade Liberalization and the Environment

This paper examines how trade liberalization affects national and global pollution in a multi‐country model incorporating monopolistic competition and intra‐industry trade as well as inter‐industry trade. Each country produces skill‐intensive differentiated goods and labor‐intensive goods. Pollution is a by‐product of production but pollution abatement can be undertaken. Regardless of country characteristics, if the differentiated‐good sector is sufficiently cleaner (dirtier) then, without any change in environmental taxes, a multilateral reduction in import protection accorded to the differentiated good or to both goods typically leads to a decline (rise) in pollution in all countries. Pollution havens tend not to arise.     

A SAVINGS SUBSIDISATION SYSTEM IN A MODEL OF ENDOGENOUS FERTILITY AND ENDOGENOUS GROWTH: AN EXTENSION OF WIGGER (1999)

Population ageing is now an established demographic characteristic of many economies. Economists working in the endogenous growth theory tradition have sought to model the relationship between public pensions, financed on a 'Pay-As-You-Go' basis, and the growth in per capita incomes. The resultant intergenerational wealth redistribution from young to older people seems to decrease private savings, diminish capital accumulation, and lower the growth of per capita incomes. The underlying transmission mechanism appears to be a crowding out effect in private capital markets contingent upon the introduction of public pension systems. A growing literature exists on the interrelationships between public pension schemes, fertility rates and endogenous growth. Following Wigger's (1999) pioneering overlapping generations endogenous growth model, we extend this model to examine the effects of a savings subsidisation system on the rate of per capita income growth, fertility and voluntary intrafamily wealth transfers, where parents view children both as an insurance good and a consumption good. Moreover, children care about the consumption levels of their parents. An increase in contributions to a savings subsidised public pension scheme will crowd out private intergenerational transfers from the young to the old and thereby negate the usefulness of children as an insurance good.     

Trade Liberalization and the Profitability of Mergers: a Global Analysis*

We analyze the effects of bilateral tariff reductions on the profitability of cost‐reducing horizontal mergers. Given Cournot competition in a two‐country world, for any positive tariff below a certain threshold, marginal trade liberalization is shown to encourage only those domestic mergers with sufficiently large cost‐savings and to discourage the rest. For tariffs close to, but smaller than, the prohibitive tariff, however, marginal trade liberalization necessarily encourages all domestic mergers. Moreover, we show that for a given level of cost‐savings, the impact of marginal trade liberalization may not reliably predict that of nonmarginal liberalization. Although at high tariffs, domestic mergers are shown to be unambiguously more profitable than cross‐border mergers, near free trade, mergers which yield the most cost‐savings become the most profitable. Thus, when comparing domestic and cross‐border mergers, trade liberalization encourages the type which yields the most cost‐savings.     

Time Preference and Trade Imbalance

This paper presents a unified theory of trade and investment in a world where the rate of time preference varies between countries. In the framework proposed by Buiter (1981 ), we can analyze a situation wherein two countries have different rates of discount. Here, the value of the debt to income does not converge to zero but remains constant even in the long run. Furthermore, we show that the existence of less‐capital‐intensive nontradables promotes capital movements: since a more patient country incompletely specializes in less‐capital‐intensive nontradables, capital must flow out of it.
