We consider a situation where the relatively ‘poor’ are concerned about their relative income status with respect to a relevant reference group. Such a concern is explicitly introduced in a utility function to study the consumption and saving behavior of the poor in terms of a static and dynamic model. The static model points toward a possible conflict between income based and nutrition-based measure of poverty. The dynamic model exhibits the possibility of a higher rate of accumulation coupled with an inadequate nutritional intake, relative to a situation where there is no such concern for status. Thus, growth with malnutrition may also imply a conflict between different measures of poverty. Both the models point toward a direct and negative relationship between inequality and share of nutritional consumption as reflected in the consumption of food. Finally the paper looks at the empirical relationship between inequality and consumption across districts within states of India. The hypotheses that inequality impacts consumption patterns via status effect cannot be rejected. In fact the impact seems to be significant across a number of the Indian states.
