“…Between-regional inequality is decomposed into subgroups including income, other diverse unit characteristics and heterogeneity which give rise to between-regional trends in inequality and inter-sectoral economics in an area (Kuncoro, 2011;Ramos & Coimbra, 2009). Some studies of inequality at different levels, ranging from international inequality (Ezcurra & Pascual, 2008;Habanik, Hostak, & Kutik, 2013;Postoiu & Bușega, 2015;Rodriguez-Pose & Ezcurra, 2010), inter-province outside of Indonesia (Antonescu, 2012;Bonet, 2006;Fitrawaty, Maipita, Hermawan, & Rahman, 2018;Islam & Noman, 2015;Wijerathna, Bandara, Smith, & Naranpanawa, 2014), inter-province in Indonesia (Aritenang, 2014;Fadli, 2014;Mahardiki & Santoso, 2013;Zakaria, 2013), inter-city outside of Java Island (Arham, 2014;Baransano, Putri, Achsani, & Kolopaking, 2016;Yuliani, 2015), Inter-city in Java Island (Abdulah, 2013;Kurniawan & Sugiyanto, 2013), regional (Cahyono, Subroto, & Anwar, 2017;Suseno, 2015) and inter-sub-district in a city (Nugroho, 2014). There is also research on pre-post-crisis inequality (Đoki, Fröhlich, & Bakaric, 2016), inequality after regional expansion (Dhyatmika & Atmanti, 2013) and differences in the conditions of inequality in origin district and newdistrict (Panjawa, Samudro, & Soesilo, 2018).…”
