Dispersive equity and social risk

Article Abstract:

Dispersive equity refers to the even distribution of risk over groups in a population. Although this concept has been receiving a lot of attention, especially from public policy decision makers, a review of existing literature revealed a considerable lack of information that would facilitate a deeper understanding of it. The present study aims to provide a more comprehensive description of the dispersive equity concept; explore other equity concepts such as individual risk equity, group risk equity, and social outcome equity; suggest evaluative models; and comment on a total equity evaluation of all equity concepts.

An experiment in approval voting

Article Abstract:

Approval voting is when one votes for or approves of as many candidates as wanted, the winner being the candidate with the most votes. Allowing more votes than the number of positions to be filled, more data from the voter is collected than collected in plurality voting. The 1985 annual election held by The Institute of Management Sciences marked the first major experimental comparison of approval voting with plurality voting. Results showed how practical approval voting can be and that a different set of candidates may be elected than those which plurality voting might elicit.
