“…First, several recent studies have documented the decline of income inequality in most Latin American countries since the early 2000s (Gasparini and others, 2009;Cornia, 2010;López-Calva and Lustig, 2010;Lustig, López-Calva and Ortiz-Juárez, 2013;Cornia, 2014;ECLAC, 2012ECLAC, , 2013ECLAC, and 2014, mainly owing to (i) a decline in the skill premium, (ii) a decrease in the urban-rural wage gap, (iii) public transfer programmes such as conditional cash transfer programmes and (iv) favourable external conditions. In addition, while taxation had a negligible effect on income inequality in previous decades (Cornia, Gómez Sabaini and Martorano, 2011), a growing body of literature has documented the positive effect of the tax reforms of the 2000s in reducing income inequality in the region (Jiménez, Gómez Sabaini and Podestá, 2010;Roca, 2009;Cetrángolo and Gómez Sabaini, 2006;Cornia, Gómez Sabaini and Martorano, 2011;Hanni, Martner and Podestá, 2015). The present paper aims to contribute to this growing literature by assessing the redistributive impact of personal income tax in Ecuador.…”
