Abstract
While the adoption of modern rice varieties (MVs) increased labour requirements for crop care and other activities, it might have induced the adoption of labour‐saving technologies. Thus, whether the net impact of MV adoption on labour demand is significantly positive is still debated in the green revolution literature. Using farm‐level survey data collected in Central Luzon from 1966 to 1990, this study estimated simultaneously the labour‐saving technology adoption and the labour demand functions. We found, among other things, that MVs increased labour demand significantly without inducing the widespread adoption of labour‐saving technologies.
