Interrelated global crises - climate change, pandemics, loss of ecosystem services and biodiversity - pose risks that demand collective solutions. Uncertainty about others' behavior, coupled with the dependence on some to take collective efforts to mitigate risks for all (e.g. conservation of...

We examine behavior in one-shot appropriation games with deterministic and probabilistic degradation externalities, where the marginal net benefit from appropriation is endogenous, dependent on individuals' expectations of group appropriation. The experimental design involves a menu of games...

We report novel results from changes in the marginal per capita return (MPCR) in a one-shot public good game where participants make a single provision decision. Data was collected using three "data collection processes": an online experiment conducted on Prolific, an online experiment conducted...

This study presents experimental evidence on the effectiveness of alternative institutional arrangements designed to allow providers of public good services to be subsidized by non-providers. The decision setting is a repeated linear public good game with two groups, insiders and outsiders....

We present experimental evidence for decision settings where public good providers compete for endogenous donations offered by outside donors. Donors receive benefits from public good provision but cannot provide the good themselves. The performance of three competition mechanisms is examined in...
