International trade theory was established as an authentic discipline of economics by the 1930s after contributions by such scholars as Gottfried Herberler, Jacob Viner, Bertil Ohlin, and Frank Graham. After World War II, its importance in economics was firmly established by the 1960s through contributions by such scholars as Paul Samuelson, James Meade, and Harry Johnson. The "Rochester School" represented by Lionel McKenzie and Ronald Jones and the "Australian School" represented by Murray Kemp have been important in the later development of the pure theory. With the advent of flexible exchange rates in the 1970s, this topic, which involves money, exchange rates, and open macro models, has appropriately assumed a prominent role in the growing field of interna- tional economics. From the days of Adam Smith, international economics has developed through its repercussions with heated contemporary issues. Fortunately, its evolution has been determined through the effort of renowned scholars in each era such as Smith, Hume, Ricardo, Mill, Marshall, and Keynes. Consequently, its popularity has furthered remarkably the overall develop- ment of economics, leading to an even greater understanding of the discipline. Economists are now equipped with a variety of theoretical and empirical tools to analyze questions in international economics and other areas. Here, we assemble illustrations of such new contributions to the field. Confining ourselves to theoretical issues, the topics we cover in this volume range from recent issues, pure theory, and macroeconomics to mathematical methods. Assigning a more detailed summary to a separate section, we might briefly sketch the contributions assembled here. This volume is divided into four parts. Part I takes up studies on recent issues in international trade and commercial policies. Ethier analyzes voluntary export restrictions. Kemp and Shimomura discuss the question of trade versus aid. Chang and Kim discuss the problem of newly industri- alizing countries (NICs) competing with developed countries. Eaton and Mirman analyze the effect of asymmetry of information and consequent IX X PREFACE signal jamming on the competition between a home firm and a foreign firm. Dei analyzes multinational corporations. Part II takes up recent topics in the pure theory of international trade. Jones and Marjit show an application of a geometric technique to a multidimensional problem concerning the Stolper-Samuelson theorem. Ide and Takayama analyze the economy with variable returns to scale and show that Marshallian stability plays a key role in economic theory involving a long-run analysis of resource allocation. Yabuuchi and Kakimoto discuss the problem of immiserizing growth under international factor mobility and variable returns to scale. Suzuki analyzes the recent topic of monopolistic competition and intra-industry trade from the view- point of a continuum of differentiated goods to investigate the question of the choice between free and controlled trade. Part III is concerned with macro problems of international economics. Ohyama clarifies the basic analytical framework for monetary economies, and he shows that the recent theory of exchange rates can be integrated into the pure theory of international trade. Ohta discusses the symmetry theorem between tariffs and quotas in the context of a monetary economy under flexible exchange rates. Adachi analyzes our experience of the stagflation era in the 1970s and the ensuing disinflation era in the 1980s by constructing a world model of two sectors, the primary good sector and the industrial sector. Part IV deals with mathematical methods and international trade the- ory. Long shows an interesting application of the Hopf bifurcation theory to the theory of international capital mobility. Nishimura is concerned with the factor price equalization theorem under a multidimensional context. Katayama, Okamura, and Tawada are concerned with the stability conditions in which parts of markets are adjusted instantaneously. Finally, we would like to mention an important reason for our collabora- tion in the present volume. We wish to honor Professor Yasuo Uekawa on his retirement from the Kobe University of Commerce in March 1990, after completing 20 years of service at the University. Professor Uekawa's background is somewhat unique. In 1944, young Uekawa was admitted to the Military Academy of Japan (analogous to West Point in the United States) after very stiff competition. He soon found himself trained as a Kamikaze pilot and had to face his death every day. Weathering the trauma of postwar Japan, he was able to obtain a university degree from the Kobe University and enrolled in its graduate program in economics. With the strong support of the late Professor Kazuo Mizutani and others, he was eventually able to go to the University of Rochester in 1963 for formal training. The Rochester Ph.D. program in economics was new at the time, having only begun in 1958. Nevertheless, the program contained excellent young professors such as Lionel McKenzie, Ron Jones, Dick PREFACE XI Rosett, and Ed Zabel. The not-so-young Uekawa finished a very tough program in three years. Rochester, even then, had able students, some of whom are now contributing articles to this volume. Uekawa's first paper, drawn from his doctoral thesis written under the guidance of Lionel McKenzie, appeared as a lead article in Econometrica in 1971. Uekawa was then "reborn" as a professional economist. He was an associate editor of the Journal of International Economics during the years 1973-1980 and 1985-1987. He has been a member of the Executive Committee of the Japan Association of Economics and Econometrics for the period of 1975 through 1981 and again from 1984 to the present. He was also a visiting professor of economics at the University of New South Wales in Australia during April 1971 through March 1972 and October 1985 through July 1986 and the Massachusetts Institute of Technology for the summers of 1976 and 1978. As friends and/or students of Professor Uekawa, the contributors are aware of the high standards that he sets for himself and his students. At the Kobe University of Commerce he left many legends, such as a number of his graduate students crying in bathrooms after hard training sessions. In spite of this and his strong inclination to pure theory, almost half of every 150 new undergraduate students in the University's Department of Economics desired to be enrolled in his "stable" or seminar, though most of such desires could not be met due to exogenous constraints. In any case, a clear majority of graduate students have "suffered" under him. Our hope here is that Professor Uekawa enjoys each contribution in this collection. AKIRA TAKAYAMA MlCHIHIRO OHYAMA HIROSHI OHTA Outline This book is divided into four parts: recent issues, pure theory, macro- economics, and mathematical methods. Part I is concerned with recent issues in international trade and commercial policies. It contains five chapters. Ethier is concerned with voluntary export restrictions (VER), which, during the last two decades, have become the most prominent means by which protectionist initiatives have been implemented in the industrial world. Ethier attempts to shed light on three questions. What distinguishes those industries in which VERs can be expected to emerge? If government policy is motivated by concern for industry welfare, what will be the effect of VERs on national welfare? How is the behavior of an economy affected if the government opts to attempt to negotiate VERs when import-competing industries run into trouble? Ethier sorts out the circumstances under which VERs might be expected to exist. His major conclusion is that a VER might in fact prove a useful instrument even in a world where policy is directed toward enhancing national welfare. He found the complex sensitivity of welfare consequences to exogenous pa- rameters a countervailing implication. His model is a partial equilibrium type model in which n domestic and n* foreign firms compete and in which the Cournot-Nash solution is the fundamental concept of equilib- rium. Kemp and Shimomura are concerned with the economics of foreign aid, and their chapter is a sequel to Kemp (Economics Letters, 1984)1 and Kemp-Kojima (1ER, 1985), for example. Country a can help country ß by adjusting its border taxes ("trade") or by adjusting its net transfers to ß ("aid"). It is asked which mixture of aid and trade achieves a's objective with minimum cost in terms of foregone «-utility. It is shown that the answer depends on the initial levels of the border taxes, on the amount of the initial net transfers, and on the extent to which a seeks to help ß. Chang and Kim address the question of export rivalry between a firm in a newly industrializing country (NIC) and another in a developed country. The chapter is motivated by the rapid expansion of exports in NICs. Exports from NICs are often finished products (such as VCRs) that are References cited in this outline are found in their respective chapters. xiii XIV OUTLINE produced with sophisticated parts which can be made only by advanced countries (such as Japan). The chapter uses a Bertrand type of duopoly model between a firm in an NIC and a firm in a developed country. The former can produce a low-quality final product by using its own intermedi- ate input or a medium-quality final product by using an intermediate input supplied by the latter which can also produce a high-quality final product for export. Using a partial equilibrium model, Chang and Kim analyze the pricing strategies and the choice of product pattern in achieving the Nash equilibria. Their chapter also analyzes the optimal tariff policy of both countries. It is concluded that the optimal policy for the government of the advanced economy is no intervention in her exports of the middle product to the NIC. This is because its producer is assumed to have the monopoly power over the pricing of that product. To the extent that the NIC's producer has the monopoly power over the pricing of the low-quality product, the NIC's government should maintain a free trade policy on this good. The NIC's government can impose a tariff on her import of the intermediate goods from the advanced country to counter its monopoly power. Novel features of the chapter by Chang and Kim are the competi- tion in quality-differentiated products and intermediate input linkage in trade. These features appear to be original in the trade literature, and these are in some respect more realistic in portraying trade rivalry be- tween advanced countries and NICs than the usual models of trade without them. Eaton and Mirman show an interesting application of a recent develop- ment in the theory of industrial organization on asymmetry of information and signal jamming to the theory of international trade. Their basic message stems from a simple but important premise: domestic firms know more about their local markets than do foreign firms. Consider two firms, the home firm H and the foreign firm F, and two markets, the home market H and the international market /. The two markets are segmented in that the price in each market is determined separately. The supply to the home market H is done only by firm H as market H is protected, while the two firms H and F compete in market /. The rivalry is formalized as a two-period model of Cournot competition. Even though the two firms do not compete in market H, the home firm has an incentive to influence the foreign firm's beliefs about its local demand, making it think that demand in the home market is low. The major result is that whether the home market is large or small, the incentive to signal jam raises the exports of the informed firm (H) and lowers its domestic sales. It then follows that the first period profit of firm F decreases and (under a reasonable condition) that of firm H increases. The incentive to signal jam creates the appearance of predatory dumping. Eaton and Mirman also conclude that while signal jamming by one firm can act to its own benefit, OUTLINE XV the overall effect is to increase total sales in the international market and to lower international price. Dei is concerned with multinational corporations (MNCs). His chapter follows Helpman (JPE, 1984, REStud, 1985) and Helpman and Krugman (1985, MIT Press) which emphasized the role of headquarter services that parent firms export to affiliates. While Helpman and Krugman utilized the Heckscher-Ohlin-type model modified by Chamberlinian monopolistic competition, Dei utilizes the Ricardian model with perfect competition. His use of the Ricardian model attempts to focus on differences in technology in a relatively simple framework. Helpman and Krugman (1985) concluded that the relatively capital-rich country tends to be the parent country of MNCs, if headquarter activities are the most capital intensive. In contrast to this, Dei concludes that the determinants of the emergence of MNCs are absolute advantage and demand conditions. The world production transformation curve plays a key role in his analysis. On this curve, there is the Ricardian point of complete specialization which is found in the traditional case where no MNCs exist. To the right of this kink, MNCs can emerge according to an absolute advantage. Part II is concerned with the pure theory of international trade and contains four chapters. Its first chapter is by Jones and Marjit. They are concerned with obtaining a further insight into the multidimensional version of the Stolper-Samuelson theorem by utilizing a simple geometric technique. In the literature there have been a number of efforts to extend the Stolper-Samuelson theorem beyond the original two-by-two mode. For example, Uekawa (Econometrica, 1971, and McKenzie Festschrift, 1979) pointed out that some severe restrictions on the production struc- ture are necessary to obtain the "strong Stolper-Samuelson (SSS) theo- rem," where the SSS theorem under a multidimensional framework states that an increase in any single commodity price causes one factor's return to rise by a greater relative amount and all other factor returns to fall (Chipman, 1ER, 1969). Jones and Marjit apply a two-dimensional geomet- ric technique, which they call the "Learner {JPE, 1987) triangle," to obtain an insight into the multidimensional case. They have shown that Kemp and Wegge's (1ER, 1969) necessary condition for the SSS theorem is also sufficient for the three-by-three case. Also, they have shown that the "produced mobile structure" introduced by Jones and Marjit (1ER, 1985) is sufficient for the SSS theorem to hold. Ide and Takayama are concerned with variable returns to scale (VRS). They point out that various paradoxical comparative statics results are obtained under VRS with regard to the price-output response and the Stolper-Samuelson and Rybczynski theorems. They then show that all these paradoxes virtually disappear if and only if the equilibrium is Marshallian stable. Furthermore, they show that the equilibrium is
