Stochastic income and conditional generosity: Experimental evidence (with Christian Kellner [Bonn], Gerhard Riener [Dusseldorf])
We study how other-regarding behavior extends to environments with income uncertainty and conditional commitments. Should fundraisers ask a banker to donate “if he earns a bonus” or wait and ask after the bonus is known? Standard EU theory predicts these are equivalent; loss-aversion and signaling models predict a larger commitment before the bonus is known; theories of affect predict the reverse. In five experiments incorporating lab and field elements (N=1363), we solicited charitable donations from lottery winnings worth between $10 and $30, varying the conditionality of donations between participants. While the results suggest some heterogeneity across experimental contexts and demographic groups, in each experiment conditional donations (“if you win”) were higher than ex-post donations. Pooling across experiments, this is strongly statistically significant; we find a 56% greater likelihood of donating and a 25% larger average donation commitment in the Before treatment. Our findings add to our understanding of pro-social behavior and have implications for charitable fundraising, for effective altruism giving pledges, and for experimental methodology.
Listen to the market, hear the best policy decision, but don’t always choose it (with Joon Song [SKKU] and Surajeet Chakravarty [Exeter])
Policymakers must often decide whether to pursue a policy that has uncertain benefits. The response of asset markets to proposed policy changes can be a valuable source of information for policy-setting. However, policymakers must take into account that an informed trader may anticipate this and protably manipulate the market. We show that it is optimal for policymakers to listen to asset markets, but they must commit (e.g., through political capital) to sometimes pursuing a policy even when the expected welfare effects are negative. Surprisingly, allowing traders to short-sell can make it easier for policymakers to induce truth-telling actions.
Exclude the bad actors, or learn about the group (with David Hugh-Jones [UEA])
Previous work finds that the threat of punishment or exclusion can increase contributions to public goods. However, not all behavior can be monitored and punished, and contributions induced under threat are less informative about true preferences. The resulting loss of information can lead conditionally-cooperative players to cooperate less when the threat is absent than they would have had there never been a threat. Our laboratory evidence -- from a two-stage public goods game with exclusion -- supports this account. Contributions under the threat of targeted exclusion were less informative of later choices than contributions made anonymously, and subjects realized this. We find evidence of conditional cooperation driven by beliefs over others' contributions. Our Anonymous treatment led to lower first-stage contributions but significantly higher second-stage contributions than our Revealed treatment. This may help explain why real world institutions often encourage anonymous contributions and loosely monitor teamwork.
Losing Face (With Thomas Gall [Southampton])
When Al makes an offer to Betty that Betty observes and rejects, Al may “lose face”. This loss of face (LoF) may cost Al utility, either directly or through reputation effects. This can lead to fewer offers and inefficiency in the context of bilateral matching problems, e.g., the marriage market, research partnering, and international negotiations. We offer a simple model with asymmetric information, a continuous signal of an individual's binary type, and a linear marriage production function. We add a primal LoF term which is distinct from standard search frictions. We characterize the stable equilibria, comparing the benchmark without LoF to a case where only one side is vulnerable to LoF, and present comparative statics. A small amount of LoF has no effect on low types' behavior, but, considering stable interior equilibria only, it will make high types on both sides more selective. A stronger LoF term drives high types out of the market, and makes low types reverse snobs, further reducing welfare. LoF also makes rejecting strictly preferred to being rejected, making the “high types reject” equilibrium stable. We can eliminate the effects of LoF by letting the vulnerable side move second, or setting up a “Conditionally Anonymous Environment” that only reveals when both parties say “yes”. We motivate our model with a variety of empirical examples, and we suggest policy and managerial implications.
