Resource-dependent households often diversify their income. We model demand for remittances and supply of off-resource labor as a joint decision, and discuss household trade-offs. We extend the off-farm labor supply literature to a rural fishery, contrasting our results to common findings in the farm literature and providing empirical evidence of the interdependence between education and family structure in determining income diversification. Using a unique dataset from Malaysia, we find that more-educated households are less likely to diversify their income, with caveats depending on family composition. Policy implications for resource management in a remittance economy with alternative livelihoods are discussed.
