In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on investment behaviour in public goods settings. Our models build on the idea that voluntary contributions to the supply of a public good might be motivated by...

This paper reports experiments designed to study strategic sophistication, the extent to which behavior in games reflects attempts to predict others' decisions, taking their incentives into account. We studied subjects' initial responses to normal-form games with various patterns of iterated...

According to the Framework Convention on Climate Change, global collective action is needed to stabilize “greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous [our emphasis] anthropogenic interference with the climate system.” The Framework Convention thus...

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate “tipping point,” is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests...

We describe non-cooperative game models and discuss game theoretic solution<br/>concepts. Some applications are also noted. Conventional theory focuses on the<br/>question ‘how will rational players play?’, and has the Nash equilibrium at its core.<br/>We discuss this concept and its interpretations, as...

In the games with population uncertainty introduced in this paper, the number and identity of the participating players are determined by chance.Games with population uncertainty are shown to include Poisson games and random-player games.The paper focuses on those strategy profiles that are most...

Networks can have an important effect on economic outcomes. Given the complexity of many of these networks, agents will generally not know their structure. We study the sensitivity of game-theoretic predictions to the specification of players’ (common) prior on the network in a setting where...

This paper provides a non-linear pricing rule for the valuation of assets on financial markets with intermediaries.The non-linearity arises from the fact that dealers charge a price for their intermediation between buyer and seller. The pricing rule we propose is an alternative for the wellknown...
