We show that: participants in these experiments are able to distinguish viable and non-viable candidates; these perceptions become clearer over time; and they affect vote choice. Moreover, we show that voters’ behavior is unaffected by whether they are asked (or not) about their perceptions of candidates’ chances of winning. We conclude that, for studying in details the determinants of voters’ choices, there is much to be gained in measuring, in a simple and direct manner, participants’ perceptions in voting experiments.

However, as is well-known by now, rational and privately informed voterswill condition their votes on being pivotal, and this may destroy their incentiveto vote informatively (according to their private information). We here restoreCondorcet's asymptotic efficiency result by way of modifying the aggregationrule in such a way that (a) voters have an incentive to vote informatively and(b) the collective decision is asymptotically efficient. The mechanism is anex-post randomization between majority rule applied to all votes and majorityrule applied to a randomly sampled subset of votes.

This was to be fulfilled through an “innovative co-construction procedure”, involving some unspecified external input alongside that from the citizens. Did inputs from the steering bodies undermine the citizens’ accountability for the output? Did co-construction help the output resonate with the general public, as is expected from a citizens’ assembly? To answer these questions, we build on our unique experience in observing the CCC proceedings and documenting them with qualitative and quantitative data. We find that the steering bodies’ input, albeit significant, did not impair the citizens’ agency, creativity, and freedom of choice. While succeeding in creating consensus among the citizens who were involved, this co-constructive approach, however, failed to generate significant support among the broader public. ...

Dans ces modèles, on suppose que l’électeur décide de son vote en fonction des pivots, c’est-à-dire des événements où son unique voix va faire une différence quant au résultat de l’élection. Les principaux messages de ces modèles sont illustrés avec des exemples simples; ils sont ensuite présentés plus en détail; on examine enfin leurs applications et limites, notamment en ce qui concerne l’économie expérimentale.
