“…Theil indices are additively decomposable and satisfy several desirable properties as a measure of regional income inequality, i.e., mean independence, population-size independence, and the Pigou-Dalton principle of transfers (Bourguignon 1979;Shorrocks 1980). An inequality index is said to be additively decomposable if total inequality can be written as the sum 1 For example, Akita and Lukman (1995), , Chen and Fleisher (1996), Daniere (1996), Das and Barua (1996), Esmara (1975), Gilbert and Goodman (1976), Green (1969), Jensen (1969), Mathur (1983), Mutlu (1991), Tabuchi (1988), Tsui (1991Tsui ( , 1993Tsui ( , 1996, Uppal and Budiono (1986), Wei and Ma (1996), Zheng (1997).…”
