Abstract
A log-log-inverse econometric model, representing nonlinear Engel curve relationship for fresh milk in Pakistan proved to be a valid estimation technique of quantity and expenditure elasticities with respect to consumers’ income. This model, when incorporated with dummy-variable for time-variations, indicated substantial changes in quantity and expenditure elasticities over time-period 2001-2005. During this period, the quantity and expenditure elasticities witnessed statistically significant changes in milk consumption. The quality elasticity of milk, which resulted as the difference between expenditure elasticity and quantity elasticity, turned out to be positive and enhanced in magnitude from 0.0532 during 2001 to 0.1684 during 2005
