Wage gap and dispersion in a partially unionized structure in Turkey

Unionization and wages: a quantile analysis

“…According to the international literature on the subject (Bloch and Kuskin, 1978;Borjas, 1979;Gyourko and Tracy, 1988;Yao and Zhong, 2013;Yilmaz and San, 2017), unions have a positive effect on wages. The methodology employed comprises the Oaxaca-Blinder decomposition on the mean (ordinary least squares); OLS weighted by propensity score matching, and recentred influence functions (RIF) regression, because the model does not presume the distribution of the dependent variable and makes it possible to visualize the results in the different income percentiles.…”

“…The results show no direct effects between migration, labour demand and wage increases through union agreements. Yilmaz and San (2017) use data from the 2004 and 2008 Turkish National Household Surveys and Oaxaca-Blinder decomposition and quantile regressions. Their results show that, on average, unionized individuals earn more, and these results hold across quantiles, indicating larger gains among unionized workers in the lower tail of the income distribution.…”

Sindicalización y salarios: análisis por cuantiles

“…De acuerdo con la literatura internacional sobre el tema (Bloch y Kuskin, 1978;Borjas, 1979;Gyourko y Tracy, 1988;Yao y Zhong, 2013;Yilmaz y San, 2017), los sindicatos afectan positivamente los salarios. La metodología empleada comprende: la descomposición de Oaxaca-Blinder en la media (mínimos cuadrados ordinarios), el mínimo cuadrado ordinario ponderado por emparejamiento por puntaje de propensión y la regresión RIF, porque el modelo no presume la distribución de la variable dependiente y permite visualizar los resultados en los diferentes percentiles de ingreso.…”
