I conduct an axiomatic analysis of voting rules in a context where voters evaluate each candidate by assigning her an evaluation from a pre-established set. I focus on additive rules, which follow the utilitarian paradigm. Characterization results are provided for each of the two prominent additive rules: Evaluative Voting when the evaluation set is finite and Range Voting when the evaluation set is [0,1].

Conventional democratic institutions aggregate preferences poorly. The norm of one-person-one-vote with majority rule treats people fairly by giving everyone an equal chance to influence outcomes but fails to give proportional weight to people whose interests in a social outcome are stronger than those of other people. This problem leads to the familiar phenomenon of tyranny of the majority. Various institutions that have been tried or proposed over the years to correct this problem-including supermajority rule, weighted voting, cumulative voting, "mixed constitutions," executive discretion, and judicially protected rights-all badly misfire in various ways, for example, by creating gridlock or corruption. This Article proposes a new form of political decisionmaking based on the theory of quadratic voting. It explains how quadratic voting solves the preference-aggregation problem by giving proper weight to preferences of varying intensity, how it can be incorporated into political institutions, and why it should improve equity.

Abstract
Populist, especially far-right populist, parties have gained votes in recent elections across Europe recently. This observation is true for Poland as well. The far-right populist party Law and Justice (PiS, Prawo i Sprawiedliwość) won the parliamentary election in 2015. Next to the well-known nativist and populist messages, PiS promoted a social policy: the Family 500+ programme. Did this programme attract voters? The findings of this study lend reason to answer the question in the affirmative. The inclusion of social policies usually associated with left-wing parties might hence be a path to be explored by other far-right populist parties as well.

We discuss sincere voting when voters have cardinal preferences over alternatives. We interpret sincerity as opposed to strategic voting, and thus define sincerity as the optimal behaviour when conditions to vote strategically vanish. When voting mechanisms allow for only one message type we show that this optimal behaviour coincides with an intuitive and common definition of sincerity. For voting mechanisms allowing for multiple message types, such as approval voting (AV), there exists no conclusive definition of sincerity in the literature. We show that for AV, voters' optimal strategy tends to one of the existent definitions of sincerity, consisting in voting for those alternatives that yield more than the average of cardinal utilities. ; Financial support from Ministerio de Ciencia y Tecnología through grants BEC 2005-00836, SEJ2005-01481/ECON and FEDER, Generalitat de Catalunya through grant 2005SGR00454 and Barcelona Economics-XREA is gratefully acknowledged.
