Effects of Transboundary Pollution on the Mode of International Trade of a Polluting Good*

By analyzing a strategic interaction between environmentally‐concerned governments, we examine how the competition mode of international polluting oligopoly is determined. We show that a resulting form of competition depends on the magnitudes of marginal damage costs and cross‐border spillover as well as on the degrees of similarities in these environment‐related parameters.     

A factor endowment theory of international trade under imperfect competition and increasing returns

Abstract.  Constructing a two‐good (competitive and imperfectly‐competitive goods), two‐primary factor (capital and labor) and two‐country model of international trade where the imperfectly‐competitive sector is subject to increasing returns to scale, we establish an oligopolistic version of the Heckscher‐Ohlin theorem.

Ergodic chaos for non‐expansive economic models**

Ergodic chaos is one of the most important concepts in the theory of nonlinear economics. Due to the lack of appropriate sufficient conditions, its reach has not been fully understood. In this paper a sufficient condition for ergodic chaos that covers non‐expansive dynamical systems is examined. By analyzing an endogenous growth model as an example, we discuss the breadth of models in which ergodic chaos can emerge.     

Why are IPOs underpriced? Evidence from Japan's hybrid auction-method offerings

We document discretionary underpricing and partial adjustment of IPO prices in the public offer tranche of Japan's hybrid auction regime, in which investor information differences are not important, there are no roadshows, preferential allocations are negligible, institutional investing is low, and the public offer tranche cannot fail. The magnitude and variation of underpricing in our sample, which spans relatively hot and cold markets, are similar to those reported for US IPOs. The evidence is most consistent with underpricing arising from an implicit contract to allocate risk related to initial mispricing where, in exchange for guaranteeing a minimum price, the underwriter participates indirectly in upside performance. The results raise important questions about interpretations of IPO underpricing in the US.     

PROBLEMS IN EXPANDING JAPAN'S IMPORTS OF MANUFACTURES FROM DEVELOPING ECONOMIES: A SURVEY*

The Japanese economy is now the second largest market economy, with a large trade surplus. And yet, Japan's imports of manufactures have long been very low relative to its GNP, when compared with other industrial countries; its ratio of manufactured imports to GNP was in the range of 2.1–2.7% in the 1980-87 period, as compared with 8.5–10.3% for the industrial countries as a whole or 4.7-7.2% for the United States. The share of developing economies in total imports of manufactures in Japan is about the same as, if not higher than, those for most other industrial countries. If Japan's ratio of manufactured imports to GNP were to rise in the future to approach closer to those of other industrial countries, Japan's imports of manufactures from developing economies could be two to three times what they are today, even if Japan's GNP does not increase at all and the share of developing economies in Japan's manufactured imports does not increase. This paper is an attempt to probe the potential of the Japanese market for imports of manufactures from developing economies in terms of rising ratio of such imports to GNP. The paper explores the reasons why Japan's ratio is exceptionally low, on the basis of existing literature. (a) Japan's ratio of manufactured imports to GNP has remained exceptionally low compared with those for other industrial countries. (b) Japan's ratio of manufactured imports from developing economies to GNP has remained distinctly low despite the recent surge in such imports. (c) If a part of the reason for the low ratio for Japan was a market access problem as often alleged, the problem is not with formal import barriers such as tariffs and formal non-tariff barriers because these barriers in Japan are no higher than in other industrial countries. As for informal import barriers, evidence found indicates that: (i) Administrative guidance and flexibly managed competition policy, which in the past had considerable effects of limiting imports, appear to have declined-in importance, but they still have import-limiting effects in certain areas. (ii) Market access difficulties involving import procedures, product standards, testing and certification requirements, which were enormous in the past, may have also decreased in severity over the last decade, but problems in these areas persist. (iii) There are aspects of the Japanese distribution system and practice that seem to make foreign access to the Japanese market significantly more difficult than the access by Japanese exporters to the markets in other industrial countries. Distribution in Japan suffers from overregulation. (iv) Users of manufactured products in Japan are sensitive to quality, perhaps more so, on the average, than in other industrial countries. Does the recent upsurge in Japan's imports of manufactures suggest that the traditional import behavior of Japan is changing? Japan's manufactured imports measured in yen increased by 18 and 27 percent in 1987 and 1988, respectively, and those coming from developing economies increased even more rapidly. There is also some evidence that price and income elasticities of demand for manufactured imports may have increased recently. These are encouraging, but it remains to be seen whether the trends will continue far enough into the future to bring Japan's import behavior more into line with those of other industrial countries. If they do, implications for the market prospects of manufactured exports from developing economies could be far-reaching. Outstanding questions are: (i) How much of the recent increase in manufactured imports is attributable to the appreciation of the yen (price effect)? How much is attributable to the increase in income or industrial output (income effect)? How much is attributable to removal of formal and informal import barriers effected so far (structural change)? Has consumer taste changed? (ii) Why have Latin American countries not been successful in promoting their exports of manufactures to Japan, when Asian exporters have been so successful? (iii) Up until now, the share of developing economies in Japan's manufactured imports has not been particularly low compared with those for other industrial countries, but is this share likely to fall or rise in the future? (iv) What is the likely impact of recently increased direct investment (DFI) by Japanese manufacturers in developing economies on the imports of their products into Japan?     

Trade liberalization,division of labor and welfare under oligopoly

Incorporating explicitly division of labor into a two-country general oligopolistic equilibrium model, we examine the effects of trade liberalization on firm productivity and welfare. We show that a tariff reduction increases the firm productivity of the trading industries but decreases that of the non-trading industries. An expansion of the trading industries, in contrast, decreases the firm productivity of both the trading and non-trading industries. We then find that a tariff reduction necessarily reduces welfare while the welfare effect of expansion of trading industries is ambiguous.     

Auditing internal transfer prices in multinationals under monopolistic competition

This paper derives an appropriate standard price that can be used by the tax authorities of a country for auditing transfer prices in multinational firms (MNFs) for the purpose of social welfare maximization of the country. We assume that the corporate tax rate in the host country, where MNFs undertake foreign direct investment to locate their manufacturing divisions, is lower than that in the home country. Our conclusion is that the tax authorities of the home country should not always force MNFs to hold down the transfer price through a too strict audit standard if it aims to maximize social welfare of the country in the long-run equilibrium. This result implies that tax authorities face a trade-off between consumer welfare and tax revenue when determining the standard price used for auditing. One notable implication is that the tax authorities should raise the upper-limit price allowed for internal transfers as the elasticity of substitution between brands for consumers decreases.     

On the asymptotic behavior of the prices of Asian options

In this paper, we study the price of a long term Asian option the pay-off of which is determined by the average price of the underlying asset during the last fixed number of days of its life. As one can imagine, it converges to the price of a plain vanilla option as the time to maturity increases. We explicitly obtained the asymptotic difference which will be useful for computing the price of Asian option in practice.
