This study explores asymmetric volunteers' dilemma (VOD) games where costs for volunteering is different among players. Diekmann (1993) conjectures that an equilibrium, in which a player with less costs contributes, is more likely to be played if it is risk dominant. We re-examined this...

The present paper fully characterizes equilibria of a generalized Volunteer's Dilemma game, which is an integration of the volunteer's dilemma game and the step-level public goods game with binary decision. We also examined the explanatory power of a widely accepted model with bounded...

We propose the minimum approval mechanism (MAM) for a standard linear public good environment with two players. Players simultaneously and privately choose their contributions to the public good in the first stage. In the second stage, they simultaneously decide whether to approve the other's...

We use an experimental lottery choice task and public goods game to examine if responsibility for the financial welfare of others affects decisionmaking behaviour in two different types of decision environments. We find no evidence that responsibility affects individual risk preferences....

We examine in detail the implementation of a project that is non-harmful for all agents as well as a project that is harmful for some agents through a unit-by-unit contribution mechanism. For a project that is non-harmful for all agents, efficient implementation is supported at one regular Nash...

Why people participate in public good provision is one of the oldest questions in Economics. In the absence of enforcement mechanisms public goods would be under-provided. I develop a dynamic model of forward-looking agents in the presence of social pressure, which provides a potential...

Understanding whether the size of the interacting group has an effect on cooperative behavior has been a major topic of debate since the seminal works on cooperation in the 1960s. Half a century later, scholars have yet to reach a consensus, with some arguing that cooperation is harder in larger...

This study investigates a free-rider problem in long-term relationships, where, due to its non-excludable nature, each player attempts to seek loopholes to impose the burden of cooperation on other players. The players establish a committee that demands that each player select an action as...
