We report the first experimental evidence on the effect of ``Demeny voting,'' wherein some people (e.g., parents) are given additional votes as proxy for the future generation (e.g., their children). In our experiment, three subjects are separated into the present and future generations, two of...

This paper analyzes a yes/no referendum in which the outcome is valid only if the voter turnout is greater than a predetermined level. Such a participation quorum is argued to induce the minority group of voters to abstain strategically. Such abstention is intended to adversely affect the...

Efficient allocations in common-pool resources cannot be accomplished when appropriators are selfish. In addition to this dilemma, using a linear approximation of best response functions at the Nash equilibrium in the common-pool resource environment, we find that the system of simultaneous...

This paper shows that second thoughts are not an innocent device in our daily life, but is human wisdom that plays an important role in resolving problems such as social dilemmas. We design a simple mechanism to achieve Pareto efficiency in social dilemmas, and then compare the performance of...

Given the substantial evidence of behavioral heterogeneity in social dilemma experiments, in this study we consider how to achieve cooperation in n-player prisoner's dilemma situations where each player has one behavioral type, either selfish or conditionally cooperative. We introduce a...

Consider a situation where players in a prisoner's dilemma game can approve or reject the other's choice such as cooperation or defection. If both players approve the other's choice, the outcome is the one they chose, whereas if either one rejects the other's choice, the outcome is the one when...

I consider systems with voluntary contribution mechanisms (VCM) in a quasilinear environment, showing that they are not asymptotically stable under simultaneous difference equations, and are structurally unstable under simultaneous differential equations. However, a VCM system is stable in a...

This study clarifies the types of motives that are important as a source of cooperation in a linear public goods experiment. Our experimental design separates the contributions due to confusion, one-shot motives (which includes altruism, warm-glow, inequality aversion, and conditional...

This paper proposes an alternative explanation for the sandwich property in voluntary contribution mechanism experiments. This property refers to the phenomenon of experimental data being ``sandwiched'' between a Nash equilibrium above the midpoint of the endowment and a Nash equilibrium below...
