α: calibrated so average coauthorship-adjusted count equals average raw count
We consider a standard, quasi-linear mechanism design setting in which agents’ outcomes consist of a binary part and a transfer, thus encompassing applications such as auctions, bilateral trade or public good provision. We augment preferences by allowing for loss aversion (Kőszegi and Rabin, 2007) and disappointment aversion (Bell, 1985; Loomes and Sugden, 1986). While the preferences induced by these models only have a trivial intersection given by classical expected utility (Masatlioglu and Raymond, 2016), we show that the optimal mechanisms for the two types of preferences are equivalent across a broad range of problems and thus display a remarkable robustness.
