This study shows the uniqueness of Nash equilibrium in the model of multiple voluntarily supplied public goods with potential contributors possessing different Cobb-Douglas preferences. This study provides a sufficient condition for uniqueness using graph theory. This sufficient condition allows...

This paper extends theory and experimentation in the context of two parties in a group who contribute to a public good with a provision point. This study analyzes the voluntary contributions game in which a public good is provided if and only if the sum of contributions meets or exceeds a...

Attempts to curb illegal activity through regulation gets complicated when agents can adapt to circumvent enforcement. Economic theory suggests that conducting audits on a predictable schedule, and (counter-intuitively) at high frequency, can undermine the effectiveness of audits. We conduct a...

In this paper we show how the Kolm triangle method, which is a standard tool for visualizing allocations in a public good economy, can also be used to provide a diagrammatical exposition of matching mechanisms and their effects on public good supply and welfare. In particular, we describe, on...

This paper extends both theory and experimentation in the context of two parties in a group who contribute to a public good with a provision point. In the voluntary contributions game in which a public good is provided if and only if the sum of contributions meets a threshold and the...

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 use quantifiers and selection functions to represent simultaneous move games. Quantifiers and selection functions are examples of higher-order functions. A higher order function is a function whose domain is itself a set of functions. Thus, quantifiers and selection func- tions allow players...

We introduce a game-theoretic model with switching costs and endogenous references. An agent endogenizes his reference strategy and then, taking switching costs into account, he selects a strategy from which there is no profitable deviation. We axiomatically characterize this selection procedure...

Bergstrom, Blume and Varian (1986) provides an elegant game-theoretic model of an economy with one private good and one public good. Strategies of players consist of voluntary contributions of the private good to public good production. Without relying on first order conditions, the authors...
