In this paper, I analyse the optimal pricing of transport services in the case where income cannot be distributed between individuals, Nowlan (1993) calculates an optimal price that maximises the social welfare function. However, he fails to compare the optimal price for the unequal income case with that for the equal income case, because of lack of an explicit model for individual behaviour. In this paper a more complete model is presented, which simplifies Nowlan's model and adds individual utility naximization under budget constraint. Then optimal prices for equal income and unequal income cases are compared.
