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?     

US external debt sustainability revisited: Bayesian analysis of extended Markov switching unit root test

The sustainability of US external debt, which has been an issue of global concern, is analyzed using a Markov switching (MS) unit root test applied to the flow of debt, i.e., the current account. The first to apply the MS unit root test to the issue of US external debt in order to examine local stationarity and global stationarity were Raybaudi et al. (2004). This paper introduces an extended MS unit root test where the transition probability is time-varying rather than fixed, as is usually the case, and the change of probability is explained by the real exchange rate, which theory suggests has a close relationship with the external balance. The extended MS unit root test calculated by the Markov Chain Monte Carlo (MCMC) method provides us with new insights on the issue of US external debt in recent years, suggesting that even though the debt/current account–GDP ratio remains relatively high, the probability of stationarity (sustainability) is unexpectedly high when recent US dollar depreciation is taken into account.     

Antecedents and consequences of the perceived adjustment of Japanese expatriates in the USA

The present study was designed to better understand the antecedents and consequences of expatriate adjustment in an international assignment. The researchers surveyed Japanese expatriates assigned to the United States. Structural equation modeling was utilized to test our hypotheses and model. The results indicated that previous knowledge of the host country, language proficiency, willingness to communicate and perception of the novelty of the host culture were differentially related to expatriates' adjustment to the host country. General and work adjustments were negatively related to expatriates' intent to return early. In addition, interrelationships among the adjustment dimensions were examined and the results indicated that general adjustment leads to work adjustment, which, in turn, influences interactional adjustment. Implications for future research are presented.     

Theoretical and experimental investigations of the performance of keyword auction mechanisms

Two keyword auction mechanisms, the Generalized Second‐Price auction (GSP) and the Vickrey‐Clarke‐Groves mechanism (VCG), were compared theoretically and experimentally. The former is widely used in practice; the latter is not, but it has a dominant strategy equilibrium where all participants bid their true values. In the theoretical investigation, by applying the “locally envy‐free Nash equilibrium” to the VCG, we found that the allocations are efficient and that upper and lower bounds of the auctioneer's revenue coincide in the two mechanisms. A laboratory experiment, in which the revenues and efficiencies were similar in both mechanisms, supported this result.     

Where do We Go From Here? New Perspectives on the Black Box in Strategic Human Resource Management Research

The main objective of the present research is to briefly review the strategic human resource management (HRM) literature from multilevel theoretical perspectives to summarize what we know about mediating mechanisms in the HR–performance relationship. By doing so, we highlight future research needs to advance theoretical understanding of the ‘black box’ in strategic HRM research. Furthermore, by offering additional theoretical perspectives that can be used to understand the mediating mechanisms at different levels, we suggest future research directions that capture the complexities associated with strategic HRM through a multilevel theoretical lens. Implications of the model are discussed.     

The differences in the economic effects between the DB plan and the DC plan

This paper investigates the differences between the defined benefit plans (DB) and the defined contribution plans (DC) in the enterprise pension programs in Japan. Attention is paid not only to the effect of labor turnover but also to the difference in various categories of workers, which are classified by gender, education, timing of labor turnover, etc. Also, we take into consideration the effect of interest rates. One important conclusion of this paper is that the DC plan is superior to the DB plan, in contrast to the common belief. J. Japanese Int. Economies 18 (4) (2004) 551–564.     

Legal Protection,Corruption and Private Equity Returns in Asia

Although trustworthiness has been described as a source of competitive advantage, its value extends to organizational governance and wealth creation. We identify the importance of the commitment–compliance continuum in the decision to trust and note that trustworthiness is a subjective perception viewed through each person’s mediating lens. That lens and each person’s interpretation of the social contract impact one’s commitment to cooperate. We suggest five propositions that integrate trustworthiness, governance, and wealth creation.     

Factors that influence physicians' recommendation of hospice care: An exploratory study

Palliative care and an array of attending services for terminally ill patients are available through over 2,465 hospices in the United States today. Although the actual number of terminally ill patients receiving hospice care has increased over the past decade, there is a growing concern of underutilization. Research has reported that despite meeting eligibility requirements only twenty-five percent of terminally ill patients have been served by hospice. Further, with a median stay of thirty days, the patients as well as their attending families may not be able to receive the full benefits of hospice care. In an effort to address these issues of underutilization, this exploratory study examines the relationship between physicians' referral behaviors and their awareness and perceived importance of selected hospice services, and agreement with hospice philosophy. Physician demographics and practice characteristics that are related to referral patterns are also identified.     

The Strategic HRM Configuration for Competitive Advantage: Evidence from Japanese Firms in China and Taiwan

The purpose of the present study was to identify the pattern of HRM practices that would lead to an improvement in business performance in Chinese- and Taiwanese-based Japanese affiliates in the light of a configurational perspective, following the current debate in the field of strategic human resource management (SHRM). In particular, a set of working hypotheses regarding the structural relationship among HRM practices for producing enhanced business results was drawn from the organizational learning theoretical framework that emphasizes a linkage between the process of learning and firm performance. Our conceptual model and specific hypotheses were examined using a sample of 286 Japanese affiliates operating in Mainland China and Taiwan. The results provided basic support for the configurational hypothesis in predicting the financial aspect of an affiliate's performance. It is argued that the findings of the study have several important implications for the untested relationships between high commitment work practices (HCWPs) and high performance work systems (HPWSs) from a Japanese management perspective. In addition, the manner in which each HRM technique can be used by Japanese overseas affiliates to enhance their learning and adaptive capabilities is discussed.
