“…This extensive literature includes studies by Sparks (1981), Miethe and McDowall (1993), Levitt (1999) and Gaviria and Pag es (2002), all presenting relevant empirical results. In Brazil, Carneiro (2000), Beato et al (2004), Gomes and Paz (2008), Carvalho and Lavor (2008), Madalozzo and Furtado (2011), and Justus and Kassouf (2013) also analyzed this issue. However, none of them performed empirical modeling using only individual data collected in rural areas.…”
