AYALA GAYTAN, Edgardo Arturo  and  CHAPA CANTU, Joana Cecilia. ¿Dónde quedó el trabajo? Una propuesta para medir la participación del ingreso laboral en México. El trimestre econ [online]. 2014, vol.81, n.324, pp.989-1015. ISSN 2448-718X.

The labor income share in the value added reported by the Mexico’s National Account System are extraordinarily small -between 0.25 and 0.3- compared with international standards. In this study we argue that there is a severe under-registration problem in the estimation of labor incomes, because of selfemployment and the omitted labor income from employers and individuals that work but receive no wages. We propose three criteria to correct the labor share, the methods estimate a shadow wage for individuals, in some variants it is done using some strong assumptions, in others it is imputed by using Mincerian wage equations corrected by self-selection bias. It is found that once the adjustments are made the income labor share increases to the range of 42 to 47% of total value added, the corrections are particularly high in agriculture, construction, commerce and restaurants and services, sectors with a high incidence of informality.
