Banks and Corporate Control in Japan

Using a large sample of Japanese firm level data, we find that Japanese banks act primarily in the short term interests of creditors when dealing with firms outside bank groups. Corporate control mechanisms other than bank oversight appear necessary in these firms. When dealing with firms in bank groups, banks may act in the broader interests of a range of stakeholders, including shareholders. However, our findings are also consistent with banks "propping up" troubled bank group firms. We conclude that bank oversight need not lead to value maximizing corporate governance.     

An adjustment cost model of long-term employment in Japan

A dynamic factor demand model is presented which pays special attention to the prevalence of a long-term employment relationship in Japan. The model is based on the representation of technology by a variable cost function with adjustment costs for employment and capital stock, where the variable cost consists of the sum of overtime costs and materials costs. With employment being quasi-fixed and scheduled hours institutionally regulated, short-run adjustments are mostly made by overtime hours. Application to a time-series data on the Japanese electrical machinery industry indicates quasi-fixity of capital and employment and reproduces short-run overshooting of overtime hours to compensate for the sluggish adjustment of employment.     

Agglomeration economies in urban manufacturing industries: A case of Japanese cities

The effects of urban agglomeration economies on productivities in two-digit manufacturing industries is estimated using the cross section data of Japanese cities in 1979. Urbanization and localization economies, which are major forms of urban agglomeration economies, are explicitly separated. The estimates of these economies vary considerably among industries. Light industries receive more productive advantages from urbanization economies than from localization economies, but heavy industries experience these economies more from localization economies than from urbanization economies.     

Transactions Accounts and Loan Monitoring

We show that transactions accounts, by providing ongoing dataon borrowers’ activities, help financial intermediariesmonitor borrowers. This information is most readily availableto commercial banks, which offer these accounts and lendingtogether. We find that (1) monthly changes in accounts receivableare reflected in transactions accounts; (2) borrowings in excessof collateral predict credit downgrades and loan write-downs;and (3) the lender intensifies monitoring in response. Thisis evidence on a key issue in financial intermediation—thereis an advantage to providing deposit-taking and lending jointly.But this advantage may have fallen as the cost of communicationhas declined.

On the impact of the tests for serial correlation upon the test of significance for the regression coefficient

Monte Carlo methods are used to investigate the relationship between the power of different pretests for autocorrelation, and the Type I error and power of the significance test for a resulting two-stage estimate of the slope parameter in a simple regression. Our results suggest it may be preferable to always transform without pretesting. Moreover we find little room for improvement in the Type I errors and power of two-stage estimators using existing pretests for autocorrelation, compared with the results obtained given perfect knowledge about when to transform (i.e., given a perfect pretest). Rather, researchers should seek better estimators of the transformation parameter itself.     

Approaches to solving China’s marine plastic pollution and CO2 emission problems

Global contamination of the oceans by waste plastics is of increasing concern. Besides being the largest emitter of CO₂ in the world, China is suspected of being the largest contributor to marine plastic waste pollution. Responsible for the latter is the still inadequate management of waste in China, a significant improvement of which is necessary for addressing the issue of marine plastic pollution. Since plastics are hydrocarbons, submitting them to appropriate waste treatment/recycling technologies could contribute to mitigating the emission of CO₂, indicating the possibility of addressing the two environmental issues simultaneously. Based on the combined use of waste input–output and linear programming, we investigated options for mitigating CO₂ emissions under consideration of alternative waste treatment/recycling processes applied to waste plastics of China. It was found that of the nine processes considered, four could result in a net reduction in the emission: a win-win situation.     

Human resource management in Asian subsidiaries: comparison of French and Japanese MNCs

European and Japanese multinational corporations (MNCs) have expanded their activities in Asia, usually through massive mobilization of various human resources from head offices, whether expatriated or on short-term assignments, and a reliance on diverse categories of local employees. Because expatriation is costly, difficult and often limited in its results, MNCs have developed localization strategies for management positions to support their regional development. This contribution addresses such a scenario by comparing Japanese and French MNCs in eight Asian countries, based on 53 interviews across subsidiaries of 17 MNCs. We find that Japanese MNCs have not localized management positions as much as French MNCs, but they have grown more willing to do so. To compensate for the lack of local capabilities without sending more expatriates, both French and Japanese MNCs frequently send experts on short-term assignments. Finally, though human resource practices vary widely across countries, even for a given MNC, some harmonizing principles have been introduced to regional HRM strategies recently.     

TECHNICAL PROGRAESS AND INVESTMENT: A VINTAGE MODEL*

The main purpose of this paper is to investigate the optimal investment decision of the firm with a vintage production function. First, the optimal conditions for the investment and replacement permitting jumps in the state variables are derived. Second the effects of exogenous parameters on investment are examined and the following new results are obtained: (1) whether a rise in the current money wage increases or decreases investment depends crucially on the time profile of the existing plants; (2) a rise in the rate of technical progress reduces investment.
