Global public goods (GPGs) are goods that are produced locally but have global effects. GPGs are essential for securing global development. The climate and biodiversity crises, pandemics, as well as fragility, conflict and violence are threatening livelihoods and well-being around the world, and...

International environmental agreements (IEAs) often condition entry into force on ratification by a minimum number of countries, yet deep environmental commitments frequently face strong domestic political resistance. We study how IEA breadth, through minimum ratification thresholds (MRTs), and...

This paper examines how religious ethic influences contributions to public goods. We develop a theoretical model distinguishing individualistic motivations - where people seek to meet individual moral standards - from collectivistic motivations - where behavior is guided by others' expectations....

This study critically and constructively assesses how 'economic games' contribute to climate policy research via a pre-registered systematic scoping review of 165 sources. Researchers use economic games as empirical tools to measure cooperation while experimentally controlling the presence,...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

We study how individuals in six Latin American countries value public versus private provision of education and healthcare using a survey experiment. Respondents were randomly assigned to vignettes that vary income, service quality, and provider type. Perceived quality is the main driver of...

I study a formal mechanism that can sustain Pareto optimality in a new and very broad class of dilemma games. In the absence of a central authority that could enforce multilateral agreements, the mechanism is based on binding unilateral commitments, which condition a playerís (possibly...

In a strategy-proof mechanism, implementation theory mostly assumes that each agent is rational in the sense that the agent reveals its true preference to induce its most preferred outcome. This assumption is sufficient to guarantee that the agent seeks such an outcome, but not necessary because...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

We leverage quasi-experimental variation to study how group size influences free-riding behavior within a high-expense environment. When buildings lack apartment-specific heat meters, tenants use simple heuristics to split a common bill. We estimate that the staggered rollout of a corrective...

Herein, we further examine how we can value nonmarket goods and services by considering the costs associated with environmental conflicts. Focusing on two American rules-the asymmetric reimbursement system and the contingent fee contract-we develop a strategic game-theoretic model in which a...

To evaluate the marginal welfare effects of taxation and of public spending, we must account for both distortionary and distributional effects. The distributional consequences of taxation, in terms of welfare, cannot be fully captured in in the measures currently used in the literature, such as...
