Existing models treat migration as either an individual or household d
ecision. In this paper, migration is modeled as the outcome of joint u
tility maximisation by the prospective migrant and other household mem
bers. This approach encompasses the Todaro and household models as spe
cial cases or a more general model. It provides a theoretical rational
e for the inclusion of a richer set of explanatory variables in an eco
nometric model of migration. Further. it links the determinants of mig
ration with existing work on remittances. Empirical evidence from a ru
ral household survey in western Kenya provides support for the model.
