Moreover, basedon the study by Mohring (1976), in the neutral economies of scale, optimization of roadcapacity can, theoretically, be achievedby appropriating the excess revenue derived from social marginal cost charging to additional investment in road capacity. To apply this approach to actual roadinvestment, however, we needto address the issues that impede the shift to optimal road capacity. In this study, we enhancedthe simulation analysis conductedin Misui andNemoto (2010, 2011), andevaluatedthe SMC charging through the examination of the relationship between the roadcapacity of the network andthe traffic environment roadusers faced. As a result, we pointedout three policy issues: (1) modification of SMC charges considering public acceptance, (2) feasibility of the optimal roadcapacity under cost-benefit criterion, and(3) long-term relationship between the urban structure andthe roadnetwork.","PeriodicalId":154016,"journal":{"name":"Hitotsubashi journal of commerce and management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122084075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper empirically analyzes the effect of multimarket contact on air carriers. pricing behaviors and the impact of market power on multimarket contact. We estimated the simultaneous demand and price (pseudo-supply) equations to derive the impacts of multimarket contact by using cross-sectional data of the year 2006 (top 30 U.S. air markets with 4484 sample observations) . We found that multimarket contact increases airfare and that if there are only full-service carriers (FSCs) in a market, the effect of multimarket contact among FSCs is enforced by their preferrence for collusion. However, if there are low-cost carriers (LCCs) in a market, the effect of multimarket contact is not enforced. We also found that in a market where LCCs have dominant market shares, multimarket contact does not necessarily result in carriers. collusive behavior. These results suggest that multimarket contact affects market performances differently depending on whether an LCC exists.","PeriodicalId":154016,"journal":{"name":"Hitotsubashi journal of commerce and management","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114227648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I suppose that the earnings attributes of persistency, predictability, and smoothness are suitable for the Japanese corporate system. This research suggests that Japanese companies possibly shift the organization-oriented corporate system to the market-oriented corporate system, if the ASB of Japan (ASBJ) adopt the presentation of the approach 1 income that is recommended by the IASB (2008). So they may have severe impacts on their corporate system or employment system because they will make it difficult to maintain the long-termrelationship between other stakeholders, which is the source of competitiveness.","PeriodicalId":154016,"journal":{"name":"Hitotsubashi journal of commerce and management","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121500254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our investigation spans the 1970-2005 period, covers ten major non-life insurers, and compares pre- and post-deregulation periods. Since portfolio considerations are essential for non-life insurers in making managerial decisions, this studyattempts to clarifythe relationship between insurer efficiencyperformance and their business portfolio. We employan ordered probabilitymodel where the dependent variable is the ranking number of insurer efficiencyderived from a fixed-effect model. Our results reveal that the efficiencyof insurers deteriorates as theydecrease their diversification. This indicates that non-life insurers can successfullyimprove their efficiencybydiversify ing their insurance policyportfolio. The contribution of market share expansion to efficiency performance differs among the various lines of insurance and regulatoryenvironments. Insurers with higher shares in the automobile insurance market tend to be more efficient than those with lower shares. In contrast, increasing the market share in fire insurance maydeteriorate insurer efficiencyin the competitive marketplace after deregulation. Market share expansion of personal accident insurance contributes to efficiencyonlyin the post-deregulation period.","PeriodicalId":154016,"journal":{"name":"Hitotsubashi journal of commerce and management","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130926913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, I use a fundamental signal (F_SCORE) to discriminate between eventual winners and losers. F_SCORE is based on a combination of traditional fundamentals such as ROA, cash flow from operations, and operating margin. I demonstrate that the mean return can be increased by at least 7.8% through hedging strategy that buys high F_SCORE firms and that shorts low F_SCORE firms. In particular, an investment strategy that buys high book-to-market (BM) firms with high F_SCORE and shorts low BM firms with low F_SCORE earns a 17.6% annual return. In other words the results are robust across a variety of partitions including size, share price, and trading volume. This study reveals that F_SCORE can predict future earnings. Further, empirical results do not support a risk-based explanation for the investment strategy.

The empirical results suggest that middle managers blindly pursue less effective business strategies (e.g., pursuit of scale economies, market share, and excessive product differentiation) even in the face of environmental change - from the market growth stage to the maturity stage in the late 1990s and thereafter.
