Abstract:

We establish a general relationship between the standard form of the individualistic social-welfare function and the ?reduced-form? version that is expressed in terms of inequality and mean income. This shows the relationship between the property of monotonicity and the slope of the equity-efficiency trade-off. Particularly simple results are available for a large class of inequality measures that includes the Gini. These results do not require differentiability of the social welfare function.
