Andreoni 1993<br />

Uses lab experiment to directly test crowdout hypothesis with<br />

“government” provision<br />

Payoffs U h = (7 − G h ) 1−α G α<br />

Two groups: no-tax and tax<br />

No-tax group can choose G h = 0, 1, 2, .., 7<br />

Tax group automatically gets 2 tokens allocated to G and can choose<br />

G h = 0, 1, 2, .., 5<br />

Each game repeated twenty times<br />

Nash equilibrium in no-tax game is G h = 3 but Pareto effi cient<br />

outcome is G h = 6<br />
