In each period of a dynamic tax-rebate program, a (fixed) quantity tax is imposed on each unit of a given good, and the tax revenue is rebated back to the consumer in the next period. The program lasts for infinite number of periods. The author considers a representative consumer’s...

This paper considers the cost sharing problem on a fixed tree network. It provides a characterization of the family of cost sharing methods satisfying the axioms of Additivity and the Independence of Irrelevant Costs. Additivity is a classical axiom. The Independence of Irrelevant Costs axiom is...

An airline lands in a number of airports in a region. An airport serves a number of airlines. Each airport charges a given amount of emission fees to those airlines using the airport. The total emission fees from all airports in the region must be shared among all airlines. We propose an...

In each period of a dynamic tax-rebate program, a (fixed) quantity tax is imposed on each unit of a given good, and the tax revenue is rebated back to the consumer in the next period. The program lasts for infinite number of periods. The author considers a representative consumer's dynamic...

A set of agents is located along a river. Each agent consumes certain amount of water he receives from his part of the river basin and may sell certain amount to his downstream agent if it is mutually beneficial. Water trading is restricted to two neighboring agents and an agent can only pass...

A polluted river network is populated with agents (e.g., firms, villages, municipalities, or countries) located upstream and downstream. This river network must be cleaned, the costs of which must be shared among the agents. We model this problem as a cost sharing problem on a tree network....
