Interpolating the Lorenz Curve: Methods to Preserve Shape and Remain Consistent with the Concentration Curves for Components

C¹‐class interpolation methods that preserve monotonicity and convexity and are thus suitable for the estimation of the Lorenz curve from grouped data are not widely known. Instead, parametric models are usually applied for such estimation. Parametric models, however, have difficulty in accurately approximating every part of income/expenditure distributions. This paper proposes two types of C¹‐class shape‐preserving interpolation methods. One is a piecewise rational polynomial interpolation (proposed independently by Stineman and Delbourgo) that enables consistent interpolation of the concentration curves for income/expenditure components, attaining approximately the same accuracy as that of the existing methods when applied to decile‐grouped data or to more detailed aggregation. Another is a Hybrid interpolation that employs pieces of curves derived from parametric models on end intervals. Empirical comparisons show that the Hybrid interpolation (with the assistance of parametric models for class‐boundary estimation) outperforms the existing methods even when applied to quintile‐grouped data without class boundaries.     

Convergence and divergence of role stress experience of locally hired Japanese and non-Japanese host country staff: a qualitative study

This qualitative study examines the role stress (comprising of role ambiguity and role conflict) experienced by locally hired Japanese (LJ) and non-Japanese (NJ) staff in a sample of Japanese companies in Australia. Expatriates were also interviewed to gather information regarding the impact of cross-cultural understanding on role ambiguity and role conflict in their work relationships with LJ and NJ staff. Both LJ staff and NJ local staff experienced two types of role ambiguity, resulting from insufficient English competence and information shortage. NJ staff experienced two additional types of role ambiguity due to their lack of cultural understanding about Japan. LJ staff experienced two types of role conflict which were not experienced by NJ local staff. These were caused by their cultural understanding about Australia, and their Japanese cultural heritage and understanding of the society and organisational processes. This study shows that cultural understanding of one's host country and parent country could reduce role ambiguity. In addition, it was found that cultural understanding of one's host country and parent country results in role conflict. These findings suggest that cultural understanding could have positive and negative consequences on role stress. Theoretical and practical implications in the management of white-collar staff in overseas Japanese companies are discussed.     

Service quality and its effect on customer satisfaction and customer behavioral intentions: hotel and ryokan guests in Japan

This study analyzes the effect of service quality on customer satisfaction and customer behavioral intentions at hotels and ryokan (traditional Japanese inns). In this empirical research, questionnaires were sent to guests at seven sites: three hotels and four ryokan. Service quality, as perceived by guests, affected customer satisfaction and customer behavioral intention. Results from this empirical study show strong evidence of service quality as perceived by guests being influenced by the type of accommodation. Also, among service quality factors, “physical aspect” had the most powerful impact on customer satisfaction and customer behavioral intention. “Creativeness” ranked second, followed by “unexpected service” and “encounter performance”. The prominence of physical aspects probably reflects the distinctiveness of the service of offering a one-night stay. However, as a certain level of physical facilities is taken for granted at lodging facilities above a certain price, “creativeness”, the second most powerful factor, becomes decisively important.     

Open-Market Stock Repurchase and Stock Price Behavior When Management Values Real Investment

This paper provides a simple explanation of open‐market stock repurchases and the stock price behavior surrounding them. There is ex ante asymmetry of information with regard to the private benefits that corporate managers can attain from real investments. In our model, open‐market repurchase announcements reveal information about the managers' private benefits when real investment opportunities are unprofitable in terms of firm values. This study differs from previous studies in that we show that announcements of open‐market repurchase programs can be believable without the restriction that the announcements are commitments. Empirically, the model simultaneously predicts that a stock price will drop prior to an open‐market repurchase announcement and will rise in response to the announcement. These predictions are consistent with stylized facts.     

Consumption-Leisure Preference Structure: A New Explanation of the Evans-Jovanovic Results for Entrepreneurial Choice

This paper extends Evans and Jovanovic’s (1989) (EJ) model to explicitly consider the latent entrepreneur’s consumption-leisure preference structure, and shows that an increase in his or her assets encourages entrepreneurial activity. This result indicates that EJ’s finding may hold without the assumption of liquidity constraints.     

A Phenomenological Approach to Inquiring into an Ethically Bankrupted Organization: A Case Study of a Japanese Company

This study introduced a phenomenological approach to the study of the companies that committed corporate crimes. The author first developed the epistemology of normative control which is based on the philosophical ground of phenomenology, sociology of knowledge, ethnomethodology, Habermas's normative theories, and Foucault's normalizing discourse in the context of organizations. He, then, showed the procedures for conducting a qualitative and phenomenological empirical case study of an aggressive Japanese company whose name appeared in the media for its scandal in Tokyo. The inquiry revealed the generative mechanism of normative control and the patterns of constructing social reality of workplaces in a Japanese company.For the sabbatical period August 1999–August 2000:     

水平轴思想——关于冲绳的“共同体意识”

“水平轴思想”是指在横向的关系中把握人际关系的想法，被这种“水平轴”意识所支撑的“共同体意志”，也还是同样在“水平轴”的方向上发挥作用，就是说，一个“共同体”在与其他“共同体”的关系中，决定自己的意志。面对其他“公共体”时，“共同体”成员的归属意识被越发强烈地激发出来。在冲绳近代化的过程中，把冲绳的一切当作异质的东西加以自我否定，试图向日本本土同质化看齐。这一切是通过把“国家”的意志转换成“冲绳的进步”和“摆脱落后”，而使人产生新型的“共同体意志”的幻想，“国家”的意志正是这样把这种幻想带给冲绳的民众。民众希望从残酷状况中挣脱出来的愿望，进一步使这种支配性的意志很容易变为现实。     

Bankruptcy dynamics in Japan

This paper attempts to enhance our understanding of macro aspects of bankruptcies in Japan. For this purpose, we estimate a vector autoregression comprised of three macroeconomic variables, two financial variables from the corporate sector and the bankruptcy rate, and construct its impulse responses. The estimation results generally show expected and consistent relationships between economic shocks and aggregate bankruptcies: in particular, a positive shock in the call rate clearly raises the bankruptcy rate. We also estimate industry-level models for manufacturing, construction, and wholesale and retail trade, the results of which show fundamental similarities, but differences as well, in the details by industry. We try to apply a standard framework for analysis aimed at establishing a clear benchmark for the study.     

The effect of collaboration network on inventors' job match,productivity and tenure

It has been argued in the economic literature that job search through informal job networks improves the employer–employee match quality. This paper argues that inventors' research collaboration networks reduce the uncertainty of firms about the match qualities of inventors prior to hiring. We estimate the effect of inventors' collaboration networks on their productivity and mobility using the U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors. The evidence from fixed-effect regressions shows that the higher productivity and longer tenure of networked inventors are not solely attributable to unobserved ability of inventors or unobserved characteristics of firms. These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks.     

Location choices of firms and workers in an urban model with heterogeneities in skills and preferences

This paper investigates the location choices of firms and workers, and the implied commuting behavior, in a city comprising several jurisdictions. Jurisdictions are geographically represented by segments that are connected to each other at the center. Each jurisdiction has its own amenities. Workers are classified into types on the basis of their skills and amenity preferences. Firms employ all types of worker. A business area may be formed in the center or in the suburban segments. A monocentric configuration arises when the commuting cost is small and heterogeneity of workers is large.
