Structural Changes and Regional Income Inequality in Indonesia: A Bi-dimensional Decomposition Analysis Structural Changes and Regional Income Inequality in Indonesia: A Bi-dimensional Decomposition Analysis 秋田, 隆裕 アキタ, タカヒロ Puji, Agus Kurniawan 宮田, 幸子 ミヤタ, サチコ Akita, Takahiro Puji, Agus Kurniawan Miyata, Sachiko Structural Change Regional Income Inequality Indonesia Bi-dimensional Decomposition Weighted Coefficient of Variation Structural Change Regional Income Inequality Indonesia Bi-dimensional Decomposition Weighted Coefficient of Variation This paper analyzes the changes in determinants of inter-provincial income inequality in Indonesia from 1983 to 2004 associated with structural changes using the bi-dimensional decomposition method of a population-weighted coefficient of variation. The method unifies two inequality decompositions by regional groups and GRP components (industrial sectors) and thus enables us to assess the contributions of GRP components to within-region and between-region inequalities, as well as to overall inequality. As the share of mining has decreased, the spatial distribution of manufacturing has played a more important role in the inequality of Sumatra and Kalimantan, while the primacy of Jakarta, with strong urbanization economies, facilitated by globalization and trade and financial liberalization, has determined much of Java-Bali's inequality and, therefore, overall inequality in Indonesia. 2009-08-01 eng departmental bulletin paper https://iuj.repo.nii.ac.jp/records/414 Economics & Management Series https://iuj.repo.nii.ac.jp/record/414/files/EMS_2009_13.pdf application/pdf 244.9 kB 2017-04-12
