Suppose that we have numerical representations (V1, ... , VI) for the preferences (≻i) of our I consumers, and we are using a weighted utilitarian social welfare functional for some given collection of weights (ai) to make social choices. Show that we can change to the (equal-weighted) utilitarian social welfare functional without changing the choices that are made by changing at the same time the numerical representations of the preferences (≻i).s
