We show that John Harsanyi’s and Ronald Dworkin’s conceptions of the veil, when modeled formally, recommend wealth allocations in conflict with the prominently espoused view that priority should be given to the worse off with respect to wealth allocation. It fol...

In this paper we construct two group oriented ) , ( n k signature schemes, one based on exponentiation of primitive root and the other on elliptic curve. The security of schemes depends on difficulty of solving the discrete logarithm problem and integer factorization problem. The message is signed with the assistance of a trusted arbitrator. The trusted arbitrator is the deciding authority for ...

This paper develops a positive model of informal justice in which rewards and punishments are not determined by an ex ante optimal contract but instead express the ex post moral sentiments of the arbitrating party. In our model, a third party arbitrator mediates a one-shot relationship between two players, one of whom can exert an externality on the other. Importantly, formal contracts are not ...

Deliberate planning systems use predictions of action-outcomes using an internal model of the agent’s environment, while habitual action selection systems learn to automate by repeating previously rewarded actions...
