In assigning the cost of a potential delay, we characterize the Shapley rule as the only rule that satisfies consistency and other desirable properties.

A rule should determine which communities become lessors, how much land they rent and at which price. Our first result is a complete characterization of the family of rules that satisfy land monotonicity and non-manipulability under land reassignment. We also define two parametric subfamilies. The first one is characterized by adding a property of weighted standard for two-person. The second one is characterized by adding consistency and continuity.

A rule should determine which lessors rent their land, in which amount and at which price. Our first result is a complete characterization of the family of rules which satisfy land reassignment and monotonicity. We define two relevant subfamilies. The first one is characterized by adding a property of weighted standard for two-person. The second one is characterized by adding consistency and continuity.

The models of the cooperative game theory are defined by a set of agents and a characteristic function (benefit or cost). The models of the non-cooperative game theory are defined by a set of agents and information structure which contains a set of actions for each agent, strategies, payoffs and the sequence of movements in the interaction of the game. In the present dissertation, models from the two categories are studied and contain asymmetric agents, with asymmetry defined from two perspectives. In some cases, asymmetry is by nature, where we consider a unique agent with different characteristics from the rest, e.g. a unique tenant and several lessors. In some other cases, asymmetry is by temporal component, where some agents can act and/or develop simultaneously and others sequentially, e.g. the activities of a complex or large project. From both perspectives, these characteristics play an important role wh...

The tenant should negotiate sequentially with each lessor for the available land. In each stage, we apply the Nash bargaining solution. Our results imply that, when all land is necessary, a uniform price per unit is more favorable for the tenant than a lessor-dependent price.

In assigning the cost of a potential delay, we characterize the Shapley rule as the only rule that satisfies Hart and Mas-Colell consistency and other desirable properties.

A rule should determine which communities become lessors, how much land they rent and at which price. We present a complete characterization of the family of rules that satisfy reassignment-proofness by merging and spliting, apart from land monotonicity. We also define two parametric subfamilies. The first one is characterized by adding a property of weighted standard for two-person. The second one is characterized by adding consistency and continuity.
