The Effects of Changes in the Legal Work Shift on Wages and Hours Worked in Colombia


  • Carlos Medina D.
  • José Escobar R.


“Estimamos el efecto de un incremento en el número de horas que definen la jornada laboral diurna por ley, sobre los salarios por hora y las horas trabajadas. Para identificar el parámetro de interés, estimamos modelos de diferencias en diferencias. Aunque los datos no contienen información en cuanto al horario de las horas trabajadas, explotamos las condiciones necesarias para que la intervención tenga un efecto sobre el horario trabajado para poder definir los grupos de tratamiento y control. Encontramos que los salarios de hombres mayores de 25 anos trabajando en la industria en las principales áreas metropolitanas de Colombia cayeron más de 11% debido a la reforma, mientras que sus contrapartes mujeres redujeron el número de horas trabajadas a la semana en 3.6 horas. Existe evidencia, aunque menos robusta, de incrementos en los salarios por hora de los trabajadores hombres en otros sectores de la economía, lo cual sugiere que los empleadores incrementaron su demanda por empleo en estos otros sectores. En general, la reforma parece haber tenido efectos positivos para todos los trabajadores afectados, con excepción de aquellos que trabajan en la industria.”
