This paper investigates the role of travel time in rationing medical care services in a developing country where monetary prices are zero. A nested multinomial logit model of provider choice is estimated using 1985 data from rural Côte d'Ivoire. Unlike previous studies of health care demand in developing countries, our results indicate that travel time plays an important role in rationing health care, and that medical care demand for poorer individuals is substantially more travel time elastic than for richer individuals.
