This study evaluates the evolution of the gender pay gap in Cameroon between 2001 and 2014 using three waves. To attain this objective, we use the Cameroon Household Surveys; we also undertake a wage decomposition which accounts for selection bias due to the fact that only employed individuals have a salary, as suggested by Neuman and Oaxaca. The results show that men have been paid more than women since 2001, and therefore the labour market undervalues the productive characteristics of women. The results also indicate that the gender pay gap persists and, furthermore, that women are discriminated against. This study indicates that the gender differences in wages are a consequence of the market structure, as a result of the differences in positions occupied by men and women in the job market.
