“…However, the literature still remains largely inconclusive. The earlier set of authors support innovation, human capital, population, income, and investments as key drivers of growth (Barro & Lee, 1993; Birdsall & Rhee, 1993; De Long & Summers, 1991; Galindo Martín, Ribeiro, & Mendez Picazo, 2012; Maria, 2010; Weng, Song, & Sheng, 2012; Ye & Sun, 2010) and complemented by recent studies (like Aydin, Alrajhi, & Jouini, 2018; Erdil Şahin, 2015; Esmail & Hemdan, 2018; Kacprzyk & Doryń, 2017; Lee, 2018; Tsaurai, 2017; Ustabaş & Ersin, 2016; Zhao, 2016) and these studies relied on the Solow model as a baseline for variables selection. Bruce and Turnovsky (2013a) have attributed the growth in the economy to demographic factors like fertility, life expectancy, age among others (see Bruce & Turnovsky, 2013b; Yew & Zhang, 2013; Mierau & Turnovsky, 2014; Bloom, Canning, & Sevilla, 2004; Well, 2007).…”
