Distributive Justice in the Lab: Testing the Binding Role of Agreement

Lorenzo Sacconi and his coauthors have put forward the hypothesis that impartial agreements on distributive rules may generate a conditional preference for conformity. The observable effect of this preference would be compliance with fair distributive rules chosen behind a veil of ignorance, even in the absence of external coercion. This paper uses a Dictator Game with production and taking option to compare two ways in which the device of the veil of ignorance may be thought to generate a motivation for, and compliance with a fair distributive rule: individually-as a thought experiment that should work as a moral cue- and collectively-as an actual process of agreement among subjects. The main result is that actual agreement proves to be necessary for agents to be led towards a fair distributive principle and to generate a significant amount of compliance in absence of external authority. This conclusion vindicates the role of actual agreements in generating motivational power in correspondence with fair distributive rules.

Comment on Lorenzo Sacconi, Marco Faillo and Stefania Ottone. Contractarian Compliance, Welfarist Justice, and Conformist Utility

This comment addresses two issues that arise in Sacconi/Faillo/Ottone's essay. The first is the problem of compliance as it arises in social contract theory. The second is the problem of avoiding an incoherence that arises in the formulation of welfarist principles of distributive justice if these principles are taken to be concerned with the distribution of welfare without restriction. Sacconi, Faillo, and Ottone define an interesting class of principles that govern only the distribution of 'material utility', which they distinguish from 'conformist utility'. Sacconi, Faillo, and Ottone are primarily concerned, however, to argue that there is a need to revise 'the utility maximization model of a rational economic man'. I discuss this claim briefly, in concluding the paper.
