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.     

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。     

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.

Collectively accepted social norms and performativity: the pursuit of normativity of globalization in economic institutions

ABSTRACT

Although the philosophical literature on social institutions has been insightful for social scientific studies, the application of its core concepts, such as collective intentionality, to real institutional dynamics remains challenging. One factor contributing to this situation is insufficient work that identifies collectively accepted social norms and shows how they constitute social institutions. Relying on the perspectives of John Searle and Raimo Tuomela, this study integrates recent analyses of the concept of performativity with discourse analysis. It presents an analytic framework, drawing on the concept of nominalization, to identify collectively accepted social norms that performatively constitute social institutions. Finally, it illustrates the identification of collectively accepted ‘globalization’ that performatively constitutes and shapes economic institutions engaged in corporate financial reporting. This study contributes to closing the gap between philosophical analyses of social institutions and social scientific studies by highlighting the performance of nominalized collectively accepted social norms.     

The Perceptual Gaps Between Companies’ and University Students’ Views on Fundamental Competencies

This study examines the gap between the competencies that companies expect of university students and those that university students believe companies are seeking. We find that a gap exists between companies’ and students’ evaluations of the competencies required in the workplace. Surprisingly, companies’ and students’ priorities related to competencies are different. Our results show that both companies and students highly value versatile personal competencies as essential skills for employees. Teamwork skills are not a top priority for companies although students value them highest of the various attributes. Gaps also exist between the two groups regarding their evaluation of personality traits. These findings contribute to the development of appropriate curricula for universities and career education.     

Welfare Analysis of Pension Reforms in an Ageing Japan

This paper uses a computable general equilibrium model with overlapping generations to explore the effects of different public pension schemes on economic welfare, and intergenerational and intragenerational equity. Besides the benchmark case based on the 2004 public pension reform, the present paper considers two alternative reforms: financing the basic pension benefit through a consumption tax, and eliminating the earnings‐related pension benefit. The simulation results suggest that even the consumption‐tax financing of only the basic pension, namely, the combination of both reforms, might not improve overall economic welfare, although it increases economic output by inducing capital formation.     

Simulating fundamental tax reforms in an aging Japan

This paper studies in a quantitative way the macroeconomic and welfare effects of introducing progressive expenditure taxation, in a situation of the aging of the Japanese population. It undertakes a simulation analysis taking account of the general equilibrium effects of intragenerational inequality, which increases with a transition to an aging society. The simulation results suggest that progressive expenditure taxation has advantages over progressive labor income taxation on the grounds of efficiency and equity. Thus, a shift to progressive expenditure taxation can overcome the large welfare loss that would occur under the current tax system as Japan ages.
