    Análisis de la deserción estudiantil en los programa de pregrado de la universidad EAFIT
    (Universidad EAFIT, 2010-04-10) Montes Gutiérrez, Isabel Cristina; Almonacid Hurtado, Paula María; Gómez Cardona, Sebastián; Zuluaga Díaz, Francisco Iván; Tamayo Zea, Esteban
    College desertion is defined as the disruption of higher education undertaken by a student. To identify its causing factors is a subject of great interest for Institutions of Higher Education, because it diminishes the potential to achieve their main purpose: to educate professionals. Therefore, this research approaches college desertion conceptually and methodologically, in order to analyze this phenomenon at EAFIT University. Our sample corresponds to cohorts 2001-1, 2002-1 and 2003-1, belonging to 14 undergraduate programs. Initially the drop-out population was studied through a descriptive exploration of some key indicators and several individual, socio-economic, academic and institutional characteristics. These were followed by two econometric modelings (transversal and longitudinal). Finally a qualitative analysis was made by applying a semi-structured interview to selected students who were classified as deserters. Results highlight a significant early desertion, associated mainly to academic variables and a lack of students’ assertiveness in their choice of undergraduate programs.

    Pass-through of International food prices to domestic ination during and after the great recession: evidence from a set of Latin American economies
    (Universidad EAFIT, 2011) Tamayo Zea, Esteban; Jalil, Munir
    We examined how international food price shocks have impacted local ination processes in Brazil, Chile, Colombia, Mexico, and Peru in the past decade -- Using impulse-response analysis coming from cointegrated VARs, we wind that international food ination shocks take from one to six quarters to pass through to domestic head-line ination, depending on the country -- In addition, by calculating the elasticity of local prices to an international food price shock, we found that this pass-through is not complete -- We also take a closer look at how this type of shock affects local food and core prices separately, and asses the possibility second round effects over core ination stemming from the shock -- We wind that a transmission to headline prices does occur, and that part of the transmission is associated with rising core prices both directly and through possible second round effects, which implies a role for monetary policy when such a shock takes place -- This is especially relevant given that international food prices have recently been on an upward trend after falling considerably during the Great Recession
