“…Rather than, or in addition to, estimating equation directly, some studies estimate TFP first and regress it on FDI spillovers and other control variables in equation . Representative examples of this are: Javorcik and Spatareanu (, 2011); Liu (); Blalock and Gertler (); Keller and Yeaple (); Barrios, Görg, and Strobl (); Fernandes and Paunov (); Merlevede, Schoors, and Spatareanu (); Newman et al (); Fatima (); Hong, Sun, and Huang (); Thang, Pham, and Barnes (); Choi and Pyun (); Lu, Tao, and Zhu (); Ebghaei and Wigley (); and Njikam and Leudjou (), as presented in Table . Note that they employ either level or first difference.…”
