Solidarity: Obligations and Expressions

Maintaining Obligations on Stative Expressions in a Deontic Action Logic

We consider the logical representation of obligations on stative expressions such as The yard must be clean in the context of legal contract formation, execution, and monitoring (cf. Wyner (2003)). In a contract, the expression may understood as an obligation to maintain a property. We use a Deontic Action Logic to represent obligations over the course of time (Khosla and Maibaum (1987) and Mey...

[Tuberculosis and solidarity].

Recent studies have estimated tuberculosis to be about 3 million years old,1 and during much of that time this disease has been our greatest scourge. It is difficult to accept that tuberculosis has been causing harm for so many millions of years and that even today...

Priority, solidarity and egalitarianism

Using the axioms of “priority” and “solidarity” (solidarity in the influences of the changes in population or resources on the original members) in a variable and potentially infinite population model, Moreno-Ternero and Roemer (2006) establish an axiomatic characterization of index-egalitarian rules. We show that similar characterization results can be established in a fixed and finite populat...

One of the most unexpected collective discoveries has been the existence of another mode of organization to achieve large−scale co−ordination. This mode relies neither on the market, where price signals perform important co−ordinating functions horizontally (as Friedrich Hayek famously stated), nor on public an...
