Poverty trap concept is widely used in development economics studies, but
it’s often attributed to households’ (or individuals) conditions themselves. This
paper proposes to analyze this concept through wage discrimination between two
groups of interest: individuals affiliated to contributive health regime and those who
belong to subsidiary regime (provided by Colombian government itself). With data
taken from the Integrated Household Great Survey (GEIH, by its acronym in
Spanish) [DANE, 2014] a decomposition study à la Oaxaca-Blinder is performed,
finding that wage differentials are due to asymmetries in capacities as to a possible
discrimination.
