In this essay I argue that one can understand the relationship between those who rule and those who are ruled in civil society as an implicit contractual relationship or contract by convention. I use variations of the extensive form Trust Game to summarize the structures of alternative forms of...

The recent renaissance of work on conventions, informal institutions, and social norms has reminded us that between the state and individual choice is a network of informal social rules that are the foundation of our cooperative social life. However, even those who appreciate the importance of...

I argue that social-contract theory cannot succeed because reasonable people may always disagree, and that social-contract theory is irrelevant to the problem of the legitimacy of a form of government or of a system of moral rules. I note the weakness of the appeal to implicit agreement, the...

I defend the claim, made in a previous paper, that ‘a Humean can be a contractarian’, against the criticisms of Anthony de Jasay. Jasay makes a categorical distinction between ‘ordered anarchy’ (which he associates with Hume) and ‘social contract theory’. I argue that Hume’s...

Most meta-ethical theories fail either for lack of real content or because they fail to make needed distinctions, or to give sufficient account of what a moral theory is about. Positing that values are intuited is useless or worse, since the very problem that gives rise to the need for morals is...

Following the recent generalization of social choice in the literature on judgment aggregation, we extend the analysis of freedom of choice from sets of alternatives to sets of opinions. We establish the analogue of the cardinality based freedom of choice measure and suggest an alternative...

We present a straightforward proof of Arrow's Theorem. Our approach avoids some of the complexities of existing proofs and is meant to be transparent and easily followed.

Social contract theory is incoherent and it does not work as desired. Among the most obvious disanalogies is that contracts are enforced by a third party, commonly the state. There is no such external enforcer for a constitution. Contractarian theorists typically ignore all such issues and use...

The article focuses on the justification provided by classical contract theory for the right of states to enact laws and the corresponding obligation of political allegiance. At first the distinction between political authority and parental authority developed by John Locke in his seminal work...

This paper studies how society votes on the payroll taxes of a basic income and a social health insurance scheme. Individuals differ along the two most important dimensions when it comes to the design of the two welfare schemes, namely, income and risk. Even though the introduction of a basic...
