The entire production chain, from biomass extraction to the final use of energy goods has to be represented – it is often necessary to look far beyond the plant, be it the agricultural product or the industrial unit processing it to generate energy. The intensity of the socioeconomic impacts may vary largely depending on the type of the venture. Reforming the energy system – boiler and turbo-generator – to produce excess electricity in a sugar-ethanol plant is certainly expensive. Yet, in operation, the system for generating electrical energy will cause little impact on income and employment. The chemical, machinery and equipment sectors, for instance, will provide inputs necessary for maintenance activities (direct effect). These sectors respond by expanding their output, causing prod...

During this span the overall gender earnings gaps dropped about 7 percentage points, while the unexplained component dropped between 3 and 4 percentage points, depending on the control variables used. The gap declined most notably among workers at the bottom of the earnings distribution, with children at home, the self-employed, part-time workers and those in rural areas—the segments of the labor market that were previously reported as having the highest unexplained gender disparities. Most of the reduction in unexplained gaps occurred within segments rather than due to the composition of labor markets. The paper additionally finds a limited role for job tenure in explaining gender wage gaps.
