Decisions and Elections

A highly accessible book offering a new interpretation and resolution of Arrow's and Sen's theorems.

Résumé
This highly accessible book offers undergraduates, graduates and professionals a new, different interpretation and resolution of Arrow's and Sen's theorems. Using simple mathematics, it shows that these negative conclusions arise because, in each case, some of their assumptions negate other crucial assumptions.
