“…These studies have shown three scenarios in the linkages between labor migration and agricultural output: (1) If there is sufficient surplus labor, remittances from family members working in cities allow rural residents to purchase high-quality seeds, fertilizers, pesticides, herbicides, and other new technology and infrastructure to boost crop yields (Stark and Bloom, 1985;Lucas, 1987;Rozelle et al, 1999;Dustmann and Kirchkamp, 2001;Woodruff and Zenteno, 2001;Brière et al, 2002;Black et al, 2003;Taylor et al, 2003;Taylor and López-Feldman, 2010). (2) In the case of a thin labor market and in the absence of surplus labor, labor withdrawal can reduce the on-farm labor as well as the agricultural output (Lipton, 1980;Clay et al, 1998;Macdonald et al, 2000;Mochebelele and Winter-Nelson, 2000;Holden et al, 2004;Strijker, 2005;Tzanopoulos et al, 2007;Yamada et al, 2007;Beyene, 2008;Brosig et al, 2009;Gray, 2009).…”
