“…Much research in the 1990s and early 2000s deals with the question of regional convergence (e.g. Borraz & López-Córdova, 2007;Calderon & Tykhonenko, 2006;Chiquiar, 2005;Díaz Bautista, 2003Díaz Bautista & Mendoza, 2004;Esquivel, 1999;Gamboa & Messmacher, 2002;Rodriguez-Oreggia, 2002Sanchez-Reaza & Rodriguez Pose, 2002) and the effects of trade liberalization and North American integration on interregional inequality (Aroca, Bosch, & Maloney, 2005;Chamboux-Leroux, 2001;Corona Jímenez, 2003;Decuir-Viruez, 2003;Díaz Bautista, 2005;Dussel Peters, 2003;Garza, 2003;Jordaan & Sánchez-Reaza, 2004;Rodríguez-Pose & Sánchez-Reaza, 2003;Sanchez-Reaza & Jordaan, 2002). With few exceptions, these studies find that while there was convergence across Mexican states from 1940 to 1980, there has been no further convergence since the beginning of the 1990s.…”
