Nichols and Zeckhauser: Simple Illustration<br />

Consider a soup kitchen as an in-kind transfer policy<br />

Let S = soup and W = wait in minutes<br />

Two agents: poor (P) and rich (R)<br />

Utility functions are increasing in S and decreasing in W :<br />

U p = 2S − .5W<br />

U r = S − 1W<br />

R has higher disutility from waiting and lower utility from soup<br />

Social welfare<br />

SWF = U p + U r<br />
