The core objective of the Mahatma Gandhi National Rural Employment Guarantee Act is to promote rural development and reduce poverty by supplementing private employment in the rural Indian economy with public employment. This paper is an attempt to verify the performance of MGNREGA by studying four sample villages from West Bengal. The study has built a social accounting matrix from which the output and employment multipliers for each village are computed. However, it shows the demand-side impact, whereas the realisation of MGNREGA’s potential positive multiplier effect depends on supply-side support, which is lacking in the villages. The paper, therefore, suggests supply-side initiatives in MGNREGA through a focus on productivity enhancement measures.
