The income elasticity of demand for healthcare being found to be less than unity implying health is a necessary good in the various empirical works (Baltagi & Moscone, 2010; Behera et al, 2020; Dianda & Sirpe, 2020; Font & Novell, 2006; Murthy & Okunade, 2009; Sen, 2005), while another group of scholars claimed health as luxury good, as its responsiveness is sensitive to income change (Gbesemete & Gerdtham, 1992; Hitris & Posnett, 1992; Kiymaz et al, 2006; Newhouse, 1977). Souliotis and Lionis (2005) stated, among the goals of social and economic development, the public health sector will be low priority area if the income elasticity of health expenditure is less than one.…”
