In the presence of inequality a status-driven utility function reconciles the conflict between income-based and nutrition-based measures of poverty. Moreover, it can explain why the poor tend to save less, an established empirical fact in the developing countries. The result is independent of the assumption of imperfect capital market. The paper attempts to integrate various strands of literature on status effects.
