This Doctoral Thesis is based on the study and development, within the field of Game Theory, of the scenarios of Transferable Utility Cooperative Cost Games, where cooperation occurs bilaterally between pairs of agents. To this end, the first part of this Thesis develops an advance in the concepts of benefactor and beneficiary, and at the same time presents a new model of Corporate Tax system, discovering and analyzing the properties that appear in coalitional cost games when there are multiple benefactors and a duality of roles, or in other words, when both roles can be played by the same player. In addition, the Shapley value as an ideal distribution criterion or rule for this type of games is established and a simplified and intuitive expression of it is presented, which greatly facilitates its calculation. In a second part, and from the biform-games structure, a hybrid scenario is studied where the agents cooperate after a first competitive phase where the players, with the objective of reducing their costs, strategically determine the level of effort they are going to devote, or in other words, the degree of cooperation with which they are going to participate, anticipating the cost reduction that would be obtained, according to the level of effort contributed, in the distribution as a result of the cooperation. After the competitive phase, we analyze and study the way in which the players, bilaterally, between pairs, cooperate according to the level of effort adopted in order to reduce their costs. To this end, a new model of cooperative games called Pairwise Effort Games (PE Games) is presented, from which the impact of bilateral efforts between pairs of players on the cost reductions resulting from cooperation is analyzed, and the existence of efficient cost allocation criteria or mechanisms that allow the gains obtained to be ideally distributed among all the players is studied. The stability of the grand coalition and the existence of allocations that incentivize all players to cooperate through an optimal level of effort are demonstrated. A family of allocations with Weighted Pairwise Reduction (WPR) is identified and presented in which the generation of such optimal level of effort is found and verified. Within this family, the rule that generates the unique efficient effort equilibrium is identified and presented.On the other hand, it is found that the distribution proposed by the Shapley value is within the WPR family, but it is also found that the incentives caused by this distribution lead to inefficient effort strategies in the competitive phase. The existence of Pairwise Effort Equilibria (PEE) in this competitive phase is found and demonstrated. Once the existence of this family of WPR partitioning values has been presented and demonstrated, a subfamily of partitionings is identified and presented where pairwise reductions are not weighted separately but instead are weighted in aggregate. This subfamily is referred to as WPAR (Weighted Pairwise Aggregate Reduction). It is proved that the level of efficiency in is lower when the pairwise reductions are weighted in aggregate for each agent instead of separately. It is identified and proposed, after the comparison between the WPR family and the WPAR subfamily, a sharing rule within the WPAR subfamily that, without reaching, as it has been indicated, the values of the optimal efficient equilibrium level, it is able to generate equilibrium efforts closer to the optimally efficient equilibrium efforts. The work contained in this doctoral thesis opens up interesting and promising lines of study and research that delve into the interdependence or complementarity between the agents and the different levels of effort carried out, as well as the development, among other lines or ways, of the study of bilateral models with multiple cost reductions and the impact that these efforts have on them.
