Behavioral Welfare <strong>Economics</strong>: Two Approaches<br />

Approach 1: build a model of why color affects choice and use it to<br />

predict which choice reveals “true” experienced utility<br />

Approach 2: Yields bounds on optimal policy<br />

L cannot be optimal given available data irrespective of positive<br />

Optimal copay bounded between M and H<br />

Key insight: no theory of choice needed to make statements about<br />

welfare (do not need to understand why color affects choice).<br />
