Stable networks

Article Abstract:

Concepts of Jackson and Wolinsky have shown that it may be impossible to generally combine efficiency and stability if the allocation rule is made anonymous on all graphs. However, if only effective graphs is arrived at, then the regulation that the allocation rule be anonymous on all graphs is unessentially compelling. A mechanism design approach is more suitable and indicates that under almost all value functions, the nonempty set stable graphs will be a subset of the effective graphs under the allocation rule which is anonymous on the domain of strongly stable graphs.

Ranking opportunity sets and arrow impossibility theorems: correspondence results

Article Abstract:

Similarities exist between the problem of ranking opportunity sets and that of social choice theory which involves putting together individual choices to come up with a general social preference structure. Rankings for freedom of choice and utility associated with the social choice theory are aggregated into a general ranking of opportunity sets. Knowledge of this relationship can help researchers draw up rules for the ranking procedure.
