This paper builds a dynamic theory of secessions, conflictual or peaceful, analyzing the forward looking interaction between groups in a country. The proposed framework allows us to jointly address several key stylized facts on secession, and generates several novel predictions. We find that if...

We model the internal game between the leader and the factions of a party, to study the effect of party leadership on electoral success. Factions are of interest or of principle. The probability of winning the election is increasing in how close the party position is to the median voter, the...

We develop a formal model of the internal game between the leader and the factions of a party, to study the effect of party leadership on electoral success. Factions are of interest or of principle. The probability of winning an election is increasing in the leader's charisma, but also in party...

Single parenthood is on the rise worldwide. While acceptance of single-parent households is increasing, some authors point out that single-parent families still suffer from negative societal attitudes compared to heterosexual two-parent families, while also being among the most vulnerable groups...

We introduce incomplete information to a multiparty election under proportional representation: each voter knows her preferences and votes strategically to maximize her payoffs, but is uncertain about the number and the preferences of the other voters. Parties are assumed to be purely office...

We present a formal model of electoral competition where parties' platforms are endogenously chosen and depend on the degree of the electoral rule disproportionality. We first show that proportional electoral systems generate centrifugal forces that increase candidate differentiation. This in...

The distribution of direct public funding to political parties is based on two criteria: (1) performance at the election (funding per vote), or (2) representation in the parliament (funding per seat). Using a two-party group turnout model, we compare the effect of the two funding systems on...

I consider a two-party parliamentary election where parties compete on a quality (or valence) dimension. First I motivate why in such an election a voter may decide to cast a blank vote. Second I define a new voting system, inspired in the standard proportional representation system, where the...
