“…Wage differentials studies have been comprehensively carried out in many countries by different methods, especially including the ordinary least squares (Casero and Seshan (2006), Garcia-Suaza et al, (2009), Andrada and Galassi (2009), Tansel and Bircan Bodur (2012), Celik and Selim (2014)), quantile regression (Budría and Pereira (2005), Tansel and Bircan Bodur (2012), Hyder and Reilly (2005), Lemieux (2006), Celik and Selim (2014), Celik and Selim (2016)), logit model (Tansel (2003) and Tansel (2005)), Oaxaca and Ransom (1994) decomposition methods (Silber and Weber (1999), Ponthieux (2005), Fortin, (2008), Ismail (2011), Ismail and Jajri (2012)),Oaxaca-Blinder decomposition methods (Blinder (1973), Oaxaca (1973), Dayioglu and Kasnakoglu (1997), Ozcan, Ucdogruk, and Ozcan (2003), Kara (2006), Gurler and Ucdoğruk (2007), Ilkkaracan and Selim (2007), Cudeville and Gurbuzer (2007), Guner (2009), Azam and Prakash (2010), Akhmedjonov (2012), Ersaslan (2012), Mercan and Karakas (2015), Zhou, Zhao, Chou, and Leivang (2019)). Gardeazabal and Ugidos (2005) extended the scalar measurement of the Oaxaca method for quantile regression as the variance of men is higher in wage distribution as the dependent variable in comparison to women.…”
