This work provides necessary and sufficient conditions for the dominance solvability of approval voting games. Our conditions are very simple since they are based on the approval relation, a binary relation between the alternatives. We distinguish between two sorts of dominance solvability and...

Approval Voting is shown to be the unique scoring rule that leads strategic voters to sincere behavior of three candidates elections in Poisson Games. However, Approval Voting can lead to insincere behavior in elections with more than three candidates.

In this paper,we show how to recover discrete-time models from their continuous-time versions through Euler discretizations. In the first part, we introduce general polynomial discretizations in backward and forward looking and we study the preservation of stability properties and local...

The rise of visual representation in economics textbooks after WWII is one of the main features of contemporary economics. In this paper, we argue that this development has been preceded by a no less significant rise of visual representation in the larger literature devoted to social and...

We propose an experimental design allowing a behavioral test of the axiom ofcompleteness of individual preferences. The central feature of our design consistsin enabling subjects to postpone commitment at a small cost. Our main result isthat preferences are significantly incomplete. We use...

Completeness, the most commonly assumed axiom in preference theory,has not received much attention from the experimental literature. Indeed,incomplete preferences model a cognitive phenomenon (an agent's inabilityto compare alternatives), and therefore cannot be directly revealed throughchoice...

It is shown that preferences can be constructed from observed choice behavior in a way that is robust to indifferent selection (i.e., the agent is indifferent between two alternatives but, nevertheless, is only observed selecting one of them). More precisely, a suggestion by Savage [Savage,...

Decision makers sometimes have to choose between alternative options about which they have no preference: either they judge the options equally valuable (indifference) or they have no judgment about their relative value (noncomparability). Choosing randomly is generally considered a natural way...
