N2 - Our paper deals with the ex-post verification of models of wage distributions designed to predict wage distributions in the last three years. We will use the prediction results of Lognormal, Lognormal (3p), Johnson SB, Log-Logistic, Log-Logistic (3p) and Normal Mixture distributions and compare them with the empirical distribution from the period 2015-2017. The selection of the used distributions is based on the wage distribution models for the years 2000-2014. Our results show, that the best (and comparable) results can be obtained using three-parameter Log-logistic distribution and Normal Mixture distribution with two components. These results confirm our expectation that due to the fact, that empirical wage distribution becomes less smooth over time, a mixture model should be preferred for the future.
