Abstract

International efforts to provide global public goods often face the challenges of coordinating national contributions and distributing costs equitably in the face of uncertainty, inequality, and free-riding incentives. In an experimental setting, we distribute endowments unequally among a group of people who can reach a fixed target sum through successive money contributions, knowing that if they fail, they will lose all their remaining money with 50% probability. In some treatments, we give players the option to communicate intended contributions. We find that inequality reduces the prospects of reaching the target but that communication increases success dramatically. Successful groups tend to eliminate inequality over the course of the game, with rich players signaling willingness to redistribute early on. Our results suggest that coordination-promoting institutions and early redistribution from richer to poorer nations are both decisive for the avoidance of global calamities, such as disruptive climate change.

  • In collective risk dilemmas and public goods games, individuals' non-binding pledges in the population can trigger conditional cooperation in subsequent rounds.

    “For example, in collective risk dilemmas and public goods games, individuals’ non-binding pledges in the population can trigger conditional cooperation in subsequent rounds17,65.”

    From Cooperation without punishment (2023) · cites this paper as [65]

    The Results (page unavailable) report that the nonbinding Pledge treatments increased group success and that players’ contributions in rounds 8–10 closely matched their pledges. The Discussion (page unavailable) says early signals of commitment appear decisive for coordination. The paper does not establish the more specific claim that pledges triggered conditional cooperation—contributions made in response to others’ pledges—in subsequent rounds. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
