1 Erratum

After publication of the research article (Amaral et al. 2015), the authors noticed that the figure citations for Figures 1 and 2 were incomplete. The authors would like to draw the reader’s attention towards the corrected Figures 1 and 2 below.

Fig. 1
figure 1

Effects of proportion of male working-age population by age-education groups (factor-price elasticities) and 90 percent confidence interval on mean real monthly earnings from main occupation (dependent variable), based on Equation (2), using the national age-education distribution (Table 1), Brazil, 1970–2010. Note: ns Non-significant. All other coefficients are significant at least at p < 0.1. Statistical significance was estimated with linear combinations of estimators in Stata (command “lincom”), taking into account the 1970 main effects interacted with each additional year. Sources: 1970, 1980, 1991, 2000, and 2010 Brazilian Demographic Censuses (Brazilian Institute of Geography and Statistics – IBGE)

Effects of proportion of male working-age population by age-education groups (factor-price elasticities) and 90 percent confidence interval on mean nominal monthly earnings from main occupation (dependent variable), based on Equation (2), using the national age-education distribution (Table 2), Mexico, 1990–2010. Note: ns Nonsignificant. All other coefficients are significant at least at p < 0.1. Statistical significance was estimated with linear combinations of estimators in Stata (command “lincom”), taking into account the 1990 main effects interacted with each additional year.
