Vertical Restraints and Market Access

This paper analyzes vertical restraints in relation to market access issues. In Section II we briefly review the recent three major trade conflicts between Japan and the USA in light of vertical restraints. In Section III we review the major policy lessons of the economics literature of vertical restraints, and analyze whether we need a special treatment for vertical restraints abroad for a market access reason. In Section IV we evaluate the policy options towards foreign foreclosure and suggest that nondiscriminatory application of foreign or home competition policy should be the mechanism to address such concern instead of trade policy actions such as voluntary import expansions.     

Geography and Demography: New Economic Geography With Endogenous Fertility

To explain the links between demographics and economic integration, we construct a new economic geography model with endogenous fertility. Labour mobility across regions results in more people flowing into highly populated regions, but lowers fertility rates there. Finally, regions are divided into one very large region with a higher real wage and another small region with a lower real wage, a higher fertility rate and a supply of workers to the large region. The population growth path resembles a logistic curve in the early phase, but population decreases in the last phase. Economic integration leads to population concentration and decreases population size.     

Contribution-proportional remuneration rule for employee inventions and its effects on effort and investment incentives

The practice of the Japanese court in case of a dispute between the employer and employee regarding the amount of remuneration for an employee invention has been to order that the additional profit from the invention be divided proportionally to their respective input contributions. We show that, if the employer’s investment and employee’s effort are weakly complementary, this rule causes the share effect (excessive incentives on the part of each party to expend investment or effort in order to increase his/her share of the surplus) to dominate the probability effect (insufficient incentives arising from the fact that each party obtains only part of the increase in the expected surplus), and thus leads to excessive investment and effort relative to the joint-payoff-maximising levels. If the court cannot capture the employer’s investment as fully as the employee’s effort, the employer’s investment may be too low compared to the joint-payoff-maximising level.     

Is corporate governance important for regulated firms’ shareholders?: Evidence from Japanese mergers and acquisitions

This paper compares the reaction of bidders’ stock prices to acquisition announcements by regulated non-financial firms, banks, and unregulated companies in Japan. Results suggest that regulated non-financial firms do not experience a significant stock price response at merger and acquisition (M&A) announcements, although banks’ and unregulated firms’ M&A announcements are regarded favorably by the stock market. Furthermore, the effect of stock option usage and strict boards on the stock price response is weak for regulated non-financial bidders. The results provide additional evidence that regulation results in managerial decisions’ having less influence on shareholder wealth and thereby changes the firm's optimal governance structure. In contrast, the results provide no clear evidence that, for bank bidders, there is a significantly stronger or weaker relationship between governance and the stock price response to an M&A announcement than that of unregulated firms or regulated non-financial firms. The result does not support the view that regulatory monitoring weakens the effect of ordinary governance mechanisms.     

Regional Economic Integration and Article XXIV of the GATT

This paper studies the economic impact of regionalism under the realistic assumptions of constant tariffs and asymmetric bloc formation. As an extension of the Krugman framework, the impact is decomposed into several components, each of which has a clear economic implication. Economic integration definitely worsens outsiders' welfare even if the external tariffs of the bloc are unraised. Bloc members' welfare first increases with the expansion of the bloc; but when about half of the world is united into the bloc, welfare begins to decrease. Simulation results shed some light on the incentive structure of major participants, who face various configurations of regional integration.     

Measurement of technical and allocative efficiencies using a CES cost frontier: a benchmarking study of Japanese transmission-distribution electricity

This paper estimates the technical and allocative inefficiencies of the transmission-distribution sector of Japanese electric utilities using a panel data during the 1981–1998 period. A stochastic production frontier of the CES form is jointly estimated with input demand equations. Taking advantage of the self-duality, we retrieve the cost frontier by which the impacts of technical and allocative inefficiencies on costs and input demands are measured. The estimated elasticity of substitution is significantly different from unity in favor of the CES specification over the Cobb–Douglas. The results show that observed costs are 9 to 48% higher than the efficient level; technical inefficiency raises costs by 1 to 28%, while allocative inefficiency does so by 8 to 30%. Although their impacts on costs are similar, technical inefficiency more fluctuates so the differences in the performance of utilities are mainly due to technical inefficiency. We also find a substantial over-utilization of capital for all utilities.

Productivity, efficiency, scale economies and technical change: A new decomposition analysis of TFP applied to the Japanese prefectures

This paper aims to examine the productivity change of the Japanese economy using the data pertaining to the 47 prefectures during the period 1981–2000. The decomposition analysis of the Hicks–Moorsteen–Bjurek productivity index is conducted to explore the sources of the productivity change. In summary, technical change and efficiency change are two of the most important components driving procyclical productivity. We find that relative their importance varies over periods. Supply shocks captured by technical change component caused upturns in productivity in the mid and late 1980s and in 1999 and 2000. Supply shocks also caused downturns in the early and mid 1990s. On the other hand, demand shocks captured by efficiency change component drove upturns of productivity in 1984, 1990 and 1996, when supply shocks were not detected. J. Japanese Int.

Cournot duopoly and environmental R&D under regulator’s precommitment to an emissions tax

This study examines the environmental R&D (E-R&D) of Cournot duopolists with end-of-pipe technology under a regulator’s precommitment to an emissions tax. Under technological spillover effect, the government invariably prefers E-R&D cartelization to E-R&D competition. Highly contrary to earlier studies, consumer surplus is not necessarily maximized by environmental research joint venture cartelization, although this offers private and social incentives.     

How do banks resolve firms’ financial distress? Evidence from Japan

The main purpose of this paper is to investigate how banks resolve firms?? financial distress in Japan. Our results show that distressed firms that have more unsecured bank debt are more likely to restructure debt successfully out of court. Second, private debt restructuring is conducted during the year in which a financially distressed firm would be compelled to report negative net worth because of substantial accounting losses if no debt restructuring plans were implemented. Third, firms that are already in a negative net worth situation are more likely to receive debt forgiveness and/or debt-for-equity swaps. Finally, both the 1-year-lagged total liabilities-to-assets ratio and accounting losses are positively related to the private workout level. These results suggest that banks resolve firms?? financial distress in shareholders?? and creditors?? interests. We argue that, along with bankruptcy laws, the stock exchange rules and the fact that banks are allowed to hold shares in these firms affect the resolution of firms?? financial distress.     

Cost analysis of leuprorelin acetate in Japanese prostate cancer patients: comparison between 6-month and 3-month depot formulations

Aims: This study aimed to evaluate the economic value for leuprorelin acetate 6-month depot compared with leuprorelin acetate 3-month depot from a societal perspective in Japanese prostate cancer patients.

Methods: The cost analysis estimated the reduction in direct and indirect costs as well as intangible costs saved by having one less injection. Claims data were used for the analyses of direct and indirect costs reduction. A discrete choice experiment based on a web-based survey estimated the monetary value of the intangible costs for one injection. Another web-based survey of prostate cancer patients, who had received treatment with leuprorelin acetate injections, was carried out to calibrate the results of the discrete choice experiment.

Results: Reductions in medical costs and loss of productivity for having one less injection in prostate cancer patients receiving leuprorelin acetate were JPY 5,670 and JPY 1,723, respectively. Intangible costs saved by using a 6-month depot formulation instead of a 3-month depot formulation for the injection of leuprorelin acetate were estimated to be JPY 19,872, including the values for a reduction in pain (JPY 3,131), injection site reactions (JPY 11,545), waiting time (JPY 9,479), and subtracting the value of medical consultation (JPY 4,283). The total cost reduction for having one less injection was JPY 27,265.

Limitations: The respondents from the internet panel provided by a survey company are not necessarily a representative population of Japanese society.

Conclusions: Leuprorelin acetate 6-month depot has an advantage in monetary value in the reduction in medical costs, loss of productivity, and intangible costs for having one less injection in prostate cancer patients compared with leuprorelin acetate 3-month depot. In the costs for treating with leuprorelin acetate, the percentage of intangible costs might not be negligible. The intangible costs will probably be actively evaluated to proceed to patient-centered healthcare in society.
