This dissertation is a collection of three essays that share one common feature: all three of them relate to the literature on Bargaining. The first and second essay are joint work with my supervisor, Professor Andrés Carvajal. In our first essay we investigate the testable implications of the Nash bargaining solution. We develop polynomial tests of the NBS under different hypothesis about the default levels. For instance, with, and without observation from the outside econometrician of the levels of utility that the individuals would have obtained outside the negotiation. We use the Tarski-Seindenberg algorithm to characterize rationalizable data as those that satisfy a finite system of polynomial inequalities. In our second essay we introduce a new equilibrium concept for games of political competition. We model electoral competition within each party, assuming inner-party members have somewhat conflicting preferences. By using the bargaining protocol à la Baron and Ferejohn (1989) we explicitly model party members’ strategic interactions, their incentives and their decision of whom to elect. Our equilibrium concept attempts to model each member’s decision as if each player were uncertain about, (i) the faction that will eventually dominate the decision made by the other party and (ii) the faction that will dominate in the party’s nomination. In the last essay I focus on one of the classical problems in bargaining: the divide the dollar problem. In our framework we assume players’ utility functions mirror selfish and Rawlsian preferences. We derive the set of subgame perfect equilibria for different arrangements of player types and study why strategic generosity emerges under the bargaining protocol we assume.
