  • A Decade of Flat Wages?

    Policy Note 2014/4 | June 2014
    In the late 1990s low unemployment rates, increases in the minimum wage, and improvements in labor productivity contributed to a boost in wages, which translated into 12.4 percent cumulative growth in real wages from the late ‘90s until 2002. Real wages then stagnated despite continued growth in labor productivity. This period between 2002 and 2013 has become known as the decade of flat wages. However, over the same period there were significant changes in the composition of the labor market. In particular, the labor force has aged and become more educated. Increases in age, experience, and education could in fact be propping up observed real wages—meaning that wages of workers with a specific age and education profile may have actually declined over the decade. This is exactly what we uncover in this policy note: what appears to have been a decade of flat real wages was actually a decade of declining real wages within age/education worker profiles.

  • Evaluating the Gender Wage Gap in Georgia, 2004–2011

    Working Paper No. 768 | July 2013

    This paper evaluates the gender wage gap among wage workers along the wage distribution in Georgia between 2004 and 2011, based on the recentered influence function (RIF) decomposition approach developed in Firpo, Fortin, and Lemieux (2009). We find that the gender wage gap decreases along the wage distribution, from 0.64 log points to 0.54 log points. Endowment differences explain between 22 percent and 61 percent of the observed gender wage gap, with the explained proportion declining as we move to the top of the distribution. The primary contributors are the differences in the work hours, industrial composition, and employment in the state sector. A substantial portion of the gap, however, remains unexplained, and can be attributed to the differences in returns, especially in the industrial premia.

    The gender wage gap consistently declined between 2004 and 2011. However, the gap remains large, with women earning 45 percent less than men in 2011. The reduction in the gender wage gap between 2004 and 2007, and the switch from a glass-ceiling shape for the gender gap distribution to a sticky-floor shape, was driven by the rising returns in the state sector for men at the bottom, and by women at the top of the wage distribution. Between 2009 and 2011, the decline in the gender wage gap can be explained by the decrease in men’s working hours, which was larger than the decrease in women’s working hours. We assess the robustness of our findings using the statistical matching decomposition method developed in Ñopo (2008) in order to address the possibility that the high degree of industrial segregation may bias our results. The Ñopo decomposition results enrich our understanding of the factors that underlie the gender wage gap but do not alter our key findings, and in fact support their robustness.

  • Explaining the Gender Wage Gap in Georgia

    Working Paper No. 577 | September 2009

    This paper evaluates gender wage differentials in Georgia between 2000 and 2004. Using ordinary least squares, we find that the gender wage gap in Georgia is substantially higher than in other transition countries. Correcting for sample selection bias using the Heckman approach further increases the gender wage gap. The Blinder Oaxaca decomposition results suggest that most of the wage gap remains unexplained. The explained portion of the gap is almost entirely attributed to industrial variables. We find that the gender wage gap in Georgia diminished between 2000 and 2004.
