Preference Monotonicity and Electoral Outcomes in a Spatial Model

I analyse informational e¢ ciency of two-alternative elections where the utility of the voters depends on the realisation of an uncertain, binary state variable about which voters receive an independent, noisy signal. I show that large elections aggregate information e¢ ciently for any voting rule in the unique equilibrium if and only if the set of voters who favour an alternative in one state ...

Electoral Systems

In previous chapters, we discussed the contextual factors that affect the development of political systems. However, the evolution of political systems is not merely a function of the economic, social, cultural, and international environments. Political democracy is also as much a product of human choices as it is a product of context, particularly the choice of institutions that help shape the...

Electoral Systems in Ambient Calculi

This paper compares the expressiveness of ambient calculi against different dialects of the pi-calculus. Cardelli and Gordon encoded the asynchronous pi-calculus into their calculus of Mobile Ambients (MA). Zimmer has shown that the synchronous pi-calculus without choice can be encoded in pure (no communication) Safe Ambients. We show that pure MA without restriction has symmetric electoral sys...

The Electoral Sweet Spot: Low-Magnitude Proportional Electoral Systems

Can electoral rules be designed to achieve political ideals such as accurate representation of voter preferences and accountable governments? The academic literature commonly divides electoral systems into two types, majoritarian and proportional, and implies a straightforward trade-off by which having more of an ideal that a majoritarian system provides means giving up an equal measure of what...
