Progressivity, inequality reduction and merging-proofness are three well-known axioms in taxation. We investigate implications of each of the three axioms through characterizations of several families of taxation rules and their logical relations. We also study the preservation of these axioms under two operators on taxation rules, the so-called convexity operator and minimal-burden operator, w...

We draw on three cases of SNS implementation and us...

Results show that individuals that identify with individualistic cultural backgrounds have larger networks of friends on socia...
