Endangered Arts? : A Historical Analysis of Classical Music’s “Asian” Turn in the Field of Reproduction and Consumption
No full textResearch Project related to Campus Space(No.2) What Facilities Are Needed to Ensure a Comfortable Student Life at Hitotsubashi University?
No full text本研究は、COVID-19流行後における一橋大学の学部生・大学院生のキャンパス施設の利用実態を明らかにし、快適な学生生活の実現に資する施設整備の方向性を検討することを目的とする。近年、オンライン授業の普及によりキャンパス滞在の必要性が低下する一方で、対面での学習や交流の意義も依然として指摘されている。こうした状況を踏まえ、大学施設の利用実態と課題を包括的に分析し、施設整備の在り方について示唆を得ることに本研究の意義がある。本研究では、一橋大学の学部生・大学院生を対象に2024年12月から2025年1月にかけてアンケート調査を実施し（有効回答数232件）、統計分析および自由記述の内容分析を行った。第3節では、キャンパス施設の利用実態を「個人作業」「コミュニケーション」「リフレッシュ」の3つの観点から整理し、図書館や学食が多機能的な空間として利用されていることを示した。しかし、第4節の分析では、施設の利用頻度や滞在時間と満足度には統計的に有意な関連が見られず、満足度はむしろ入学前の期待とのギャップによって左右されることが明らかとなった。これは、施設の多機能性が学生の快適性を必ずしも保証するものではなく、施設の運用方法や利用環境の整備が重要であることを示唆している。さらに、第5節の自由記述分析では、「空きスペースの確保」「空調設備の改善」「トイレ環境の整備」「コンセント・充電環境の充実」など、施設に関する具体的な課題が多数指摘された。これらの結果を踏まえ、「一橋大学生の快適な学生生活のために求められる施設は、ひとつの利用目的に限定されたものではなく、学生の多様な活動を可能にする多機能的な施設である」と結論づけられる。そして、多機能的な施設の整備は、新たな施設の増築のみならず、空き教室の開放に関するルールの変更によっても実現可能である。本研究は、学生生活の充実度を向上させるためには、多機能的な施設の重要性が高く、特に既存の施設の開放に関するルールの見直しが望ましいことを示した
Refining Real Consumption : Accounting for In-Kind Transfers, Imputed Rents, and Preference Heterogeneities
No full text6 January, 2025Over the past decade, expanded government in-kind transfers such as healthcare and education have influenced household welfare in many countries. To capture their effects on consumption inequalities, this study introduces an acquisition-based consumption measure that includes in-kind transfers and imputed rents, deflated using a superlative index. Using Japanese data from 2005 to 2021, we find that while conventional measures indicate an 11.2 percent decline in consumption among younger households, our index shows a 6.3 percent increase. Of the resulting 17.5 percentage-point gap, 10.7 points come from the deflator choice, while the rest arises from including in-kind transfers and imputed rents.日本学術振興会23H00799時点・地点間で財が異なる場合の集計方法・指数構築に関する考察Japan Society for the Promotion of ScienceThis research was supported by the Joint Usage/Research Center at the Institute of Economic Research, Hitotsubashi University (IERPK2315, IERPK2405), and by MEXT/JSPS KAKENHI (23H00799, 24H00012)
Regional Variation and the Asian Little Divergence
No full textComparing the major Asian economies of China, India and Japan without taking account of variations in size suggests that the Asian Little Divergence began in the eighteenth century when Japan overtook first India and then China. However, the Great Divergence debate has focused on when the leading regions of the declining countries first fell behind and there was significant regional variation in GDP per capita in all three countries. Allowing for regional variation significantly changes the dating of the Asian Little Divergence: (1) In China, the Yangzi Delta, with a population about the same size as the whole of Japan, did not fall behind until around the time of the Meiji restoration in 1868. (2) In Japan, the Kinai region forged ahead of the Yangzi Delta around 1800. (3) In India, Mysore remained behind the Yangzi Delta throughout the period 1600-1870 and therefore has less significance for the timing of the Asian Little Divergence

Evaluative Perspectives on the Policy Method Introduction in Japanese Local Governments : Implementing Evidence-Based Policy Making (EBPM) Across All Departments in the Adachi Ward, Tokyo
No full textExploitation : Theory and Empirics
No full textThis paper develops a novel axiomatic analysis of exploitation as the unequal exchange of labour, derives an empirical exploitation index at the individual level, and provides the first estimation of the distribution of exploitation in the US in 1975-2022. We show that, among possible definitions of exploitation, only one satisfies a small set of formally weak and normatively salient axioms. From this definition, we derive an individual-level exploitation intensity index which provides a new measure of well-being and inequality, complementary to existing ones and able to jointly take into account the distributions of income and work time. In US data, exploitation intensity provides additional information compared with standard income inequality measures and predicts important well-being and political outcomes. Inequality in exploitation increased more than income inequality since 1975.First Draft: April 16, 2025 , This Version: May 13, 202
