“…On one hand, there is a positive relationship between farm size and productivity in new continental countries such as the United States, Canada, Australia (MacDonald, Hoppe, and Newton 2017;Sheng and Chancellor 2018), and some Latin American countries (Deininger and Byerlee 2012). On the other hand, an inverse relationship between farm size and productivity is widely observed in many Asian countries (Sen 1962(Sen , 1966(Sen , 1975Bardhan 1973;Lipton 1993;Dyer 1996;Heltberg 1998;Hayami 2001Hayami , 2009. Recently, more evidence for the inverse farm size-productivity relationship are also found in Sub-Saharan Africa (Barrett, Bellemare, and Hou 2010;Carletto, Savastano, and Zezza 2013;Larson et al 2014;Bevis and Barrett 2017;Desiere and Jolliffe 2018).…”
