With the foundation of new economics of labour migration (NELM) theory the study has made an attempt to examine the influence of migration of labourers from domestic agriculture on household crop income using primary data collected from 224 farm (cultivator) households in Nagaon and Morigaon districts of Assam. Three stage least squares estimation technique was applied for jointly determining the factors influencing migration, remittances and their impact on crop income. The analysis of the data reveals that though outmigration of labourers from domestic agriculture significantly reduced household crop income, the inflow of remittance has helped in stimulating the earnings from the cultivation of crop. The migration in the study area is considerably influenced by household size, total value of assets holding, networking influence, proximity to commercial bank and flood proneness of the village while the number of migrants, dependents, and age of migrants emerge to be strong predictor of inflow of remittances. The findings of present study offer evidence in support of NELM theory.
