“…This has been found in the studies of Bernheim (1988), Celik and Deniz (2009), and Ganchev, Stavrova, and Tsenkov (2012) who employed panel data analysis to demonstrate the existence of twin deficit hypothesis. Furthermore, various econometric techniques such as OLS, cointegration, autoregressive distribution lag (ARDL), and VARs have been used to illustrate that twin deficit holds in different countries (Akosah, 2013;Aworinde, 2013;Azgün, 2012;Celik & Deniz, 2009;El-Namrouty & Saidam, 2015;Ganchev et al, 2012;Njironge et al, 2014;Ogbonna, 2013).…”
