Intangibles and the Gender Wage Gap: An Analysis of Gender Wage Gaps Across Occupations in the Finnish Private Sector

The paper compares the gender wage differentials of two occupation groups—innovation and non-innovation workers—separately
for manufacturing and services using Finnish private-sector data. We apply a decomposition method based on unconditional quantile
regression techniques to identify key factors underlying the gender wage gaps observed along the whole wage distribution,
as well as changes in these wage gaps between 2002 and 2009. This more nuanced approach provides important new insights. We
find conspicuous differences in average gender wage gaps, in gender wage-gap profiles across the wage distribution and also
in the evolution of gender wage differentials over time between sectors and occupation groups. Our results imply that sector-specific
factors are a more important driving force behind these differences in patterns and trends of gender wage gaps, although occupation-specific
factors cannot be totally dismissed. Hence, comparisons of gender wage gaps, including their underlying sources, of innovation
and non-innovation workers for too broadly defined segments of the labour market may result in misleading conclusions concerning
the factual role of intangible capital.
