“…Different authors have assumed different technologies; for instance, Krugman (1988) postulates linear technologies in both sectors, Dornbusch (1989) assumes linear (or Leontief) technology in the production of nontradable goods, De Gregorio and Wolf (1994), García (1999) and Lartey (2008) propose linear technology in the non-tradable sector, but Cobb-Douglas in the tradable sector, Asea and Corden (1994), Asea and Mendoza (1994), Alberola (2003), Rodrik (2006), Galstyan and Lane (2009), Soto and Elbadawi (2008), Ismail (2010), García-Cicco and Kawamura (2015) and Mejalenko (2015) are based on Cobb-Douglas technologies in both sectors, Calderon (2002) and Aguirre and Calderon (2005) assume linear technologies in the non-tradable sector, but endowed tradable goods and Razmi et al (2009) postulate Leontief technologies in the tradable sector, but Cobb-Douglas in the non-tradable sector. Devarajan et al (1991) go further assuming a transformation curve between tradable and non-tradable goods with CES structure.…”
