When truth conflicts with efficiency, can verbal communication destroy efficiency? Or are lies or vagueness used to hide inconvenient truths? We consider a sequential 2-player public good game in which the leader has private information about the value of the public good. This value can be low,...

This paper compares the effects of two leadership styles: leading by pre-game communication and leading by example using an iterated voluntary contribution game. We find that pre-game communication increases the level of individual contributions in the game and has essentially the same impact on...

We examine communication in a 2-player sequential public good game in which the leader has private information about the return from contributing to it. The leader decides first and the follower observes the leader's contribution, before deciding whether or not to contribute. Without...

In economic environments, decision-makers can strategically delay irreversible investments to learn from the actions of others. This creates free-riding incentives and can lead to socially suboptimal outcomes. We experimentally examine if and how communication mitigates this free-riding problem...

We study a laboratory social dilemma game in which incentives to steal from others lead to the socially inefficient diversion of resources from production unless the members of a given mini-society can abide by norms of non-theft or engage in low cost collective protection of their members'...

Twenty-four laboratory sessions were conducted to evaluate the roles of communication and group heterogeneity when voluntary contributions determine the level of public good provision by small groups of individuals. Simple heterogeneity has one individual in a group having either greater...

Consumers can often allocate resources to the provision of local public goods and to the provision of global public goods. This paper reports a public goods experiment in which participants allocated tokens to a local exchange with a relatively high marginal payoff and a global exchange with a...

One of the most consistent findings in experimental studies of social dilemmas is the positive influence of face-to-face (FtF) communication on cooperation. The FtF "communication effect" has been recently explained in terms of a "focus theory of norms": successful communication focuses agents...

In this paper, we study a voluntary contribution mechanism with one-way communication. The relevance of one person's words is assessed by assigning exogenously the role of the "communicator" to one group member. Contrary to the view that the mutual exchange of promises is necessary for the...

We study a laboratory social dilemma game in which incentives to steal from others lead to the socially inefficient diversion of resources from production unless the members of a given mini-society can abide by norms of non-theft or engage in low cost collective protection of their members'...
