Nous exploitons dans cet article la théeorie des indices de pouvoir pour éevaluer les infuences respectives des deux classes d’électeurs dans le mode de scrutin instauré par la loi électorale du 29 juin 1820, dite loi du \double vote". Nous montrons, à l’aide d’un modèle simplifié,...

We show that a transfer targeting a minority of the population is sustained by majority voting, however small the minority targeted, when the probability to receive the transfer is decreasing and concave in income. We apply our framework to the French social housing program and obtain that...

We analyze and evaluate the di¤erent decision rules describing the Council of Ministers of the EU starting from 1958 up to now. Most of the existing studies use the Banzhaf index (for binary voting) or the Shapley-Shubik index (for distributive politics). We argue in favor of the nucleolus as a...

We look at the consequences of allowing public health insurance (PuHI) to be voluntary when its coverage can be supplemented in the market. PuHI redistributes with respect to risk and income, and the market is affected by adverse selection. We argue that making PuHI voluntary does not lead to...

A model of entrepreneurial choices in an economy with a corrupt public procurement sector is built, providing predictions along two main dimensions. First, corruption is more frequent in sectors where public institutions are large buyers. Second, firms favoured with corrupt contracts enjoy extra...

The main purpose of this paper is to estimate the probability of casting a decisive vote for a class or random electorate models encompassing the celebrated IC and IAC models. The emphasis is on the impact of correlation across votes on the order of magnitude of this event. Our proof techniques...

In this paper, we clarify the relationship between influence/power measurement and utility measurement, the most popular two social objective criteria used when evaluating voting mechanisms. For one particular probabilistic model describing the preferences of the electorate, the so-called...

We study, both theoretically and experimentally, the relation between preferred majority thresholds and behavioral traits such as the degree of risk aversion and the subjective confidence on others preferences over the alternative to vote. The main theoretical findings are supported by...

Voting is a lottery in which an individual who is uncertain about how the others vote wins if she belongs to the majority or loses if she falls into the minority. The risk of losing can be reduced by increasing the majority threshold. This however has the negative effect of also lowering the...

This paper considers a common n-agent symmetric rent-seeking game. It derives conditions so that risk-aversion and risk always decrease rent-seeking efforts. These conditions hold for any regular contest success function when risk-averse rent-seekers are also prudent. Under n = 2, prudence is a...
