Many fundraisers report donations using categories such as more than £ 1000, more than £ 10,000, etc. One naturally wonders how we should categorise donations and whether categorising raises more than simple uncategorised reporting. To answer these questions, we employ a signalling game...

In a signalling model of conformity, we demonstrate that naïve observers, those that take actions at face value, constrain the set of actions that can possibly be social norms. With rational observers many actions can be norms, but with naïve observers only actions close to that preferred by...

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...

In this paper we analyse the effect that naïve agents (those who take behavior 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 naïve inferences in tandem with standard Bayes rational...

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...
