Dynamic patterns in similarity-based cooperation: an agent-based investigation

Understanding what motivates and fosters collective actions has major implications in the governance and management of organizations, in the regulation and design of public policies, and has long attracted the interests of scholars and practitioners in business and economics. This paper deals with how groups of agents emerge in a dynamic contest characterized by lack of formal structure and uncertainty regarding the possible individual outcomes, focusing on the features of the cooperators and on the dynamics emerging among them. Through the development of a stylized agent-based model we start by showing how similarity in values can be a successful driver for cooperation but are also able to highlight the limits of such process, by looking at how and how much agents cooperate with similar others. A second-version of the model, where memory of past interactions has a role, introduces further dynamics and is able to create successful and relatively stable groups

Patriotism and taxation

The provision of public goods by any government generally requires a significant amount of financial resources. Yet the inherent characteristics of public goods imply that individuals who refuse to contribute financially cannot easily be excluded from the benefits provided by public goods. This chapter explores how, and when, patriotism can increase private incentives to make contributions to the common good – and thereby mitigate the free rider problem at the heart of public finances. We discuss this patriotism-taxation relation in times of war as well as peace and evaluate whether patriotism might help to (partially) moderate the incentives to avoid or even evade taxes. Finally, we consider the role of two potential mechanisms – i.e., migration and identification – underlying the patriotism-taxation relation and examine governments’ incentives to invest in instilling patriotic sentiments in the population for fiscal reasons
