We contrast and compare three ways of predicting efficiency in a forced contribution threshold public good game. The three alternatives are based on ordinal potential, quantal response and impulse balance theory. We report an experiment designed to test the respective predictions and find that...

We consider a model of conformity that permits a non-conformist equilibrium and multiple conformist equilibria. Agents are assumed to behave according to a best reply learning dynamic. We details the conditions under which a social norm and conformity emerge. The emergence of conformity depends...

We consider a simple model that combines elements of search and social learning. Acting in sequence, and observing the action adopted by a previous agent, agents must search for an action. We explore why agent heterogeneity may increase expected payoffs and demonstrate that social learning may...

We consider a dynamic model of conformity that permits both a conformist and a non-conformist equilibrium. We provide conditions under which conformity can 'invade' a population. More precisely, starting from a non-conformist equilibrium, we show that the conformity of an arbitrarily small...

Many charities report donations using categories. We question whether such category reporting increases donations in a signalling game where a donor is either generous or not generous. Conditions are derived under which category reporting will increase giving or decrease giving. Category...

We investigate, experimentally, the effects of leadership in a four player weak-link game. A weak-link game is a coordination game with multiple Pareto-ranked Nash equilibria. Because the more efficient equilibria involve a degree of strategic uncertainty groups typically find it difficult to...

We analyze a coordination game characterised by varying degrees of conflict of interest, incentive to coordinate and information asymmetry. The primary objective is to question whether endogenous leadership better enables coordination. A secondary objective is to question whether preference and...

We model a simple dynamic process in which boundedly rational agents learn through their interactions with others. Of interest is to study the process of contagion where by one action 'spreads throughout the population' and becomes conventional. We vary the network of player interaction between...

An individual’s contribution to a public good may be seen by others as a signal of attributes such as generosity or wealth. An individual may, therefore, choose their contribution so as to send an appropriate signal to others. In this paper we question how the inferences made by others will...

In this paper we analyse the effect that naive agents (those who take behaviour at "face value") have on the nature of social norms. After reviewing the use of signalling models to model conformity, we argue in favour of modelling naive inferences in tandem with standard Bayes rational...
