This paper considers a trading problem on a network with incomplete information. We consider a simple water trading problem in which three agents are located in a linear order along a river. Upper stream agents can sell some amount of the water to their downstream but not the other way around....

We analyze optimal trading mechanisms in environments where each trader owns some units of a good to be traded and may be either a seller or a buyer, depending on the realization of privately observed valuations. First, the concept of virtual valuation is extended to ex ante unidentified...

We analyze optimal trading mechanisms in an exchange economy where each trader owns some units of a good to be traded and may be either a seller or a buyer, depending on the realization of the privately observed valuations. The concept of virtual valuation is extended to ex ante unidentified...

For a tolled highway where consecutive sections allow vehicles enter and exit unrestrictedly, we propose a simple toll pricing method. We show that the method is the unique method that satisfies the properties of Transit-proofness (No Merging or Splitting) and Cost Recovery. The...

A river carries pollutants to people living along it if it is polluted. To make the water in the river clean, some costs are incurred. This poses a question of how to split the costs of cleaning the whole river among the agents located along it. To answer this question, we resort to the two main...

We establish a new envelope theorem in which the choice variables are discrete and the objective function and the constraints are Lipschitz continuous with respect to the parameters. The parameters can be ?nite or in?nite dimensional vectors in a Banach space. In an application, we revisit the...

This paper relates the classical Charnes, Cooper and Rhodes' (CCR) model in Data Envelopment Analysis (DEA) to the Weak Axiom of Profit Maximization (WAPM) in Firm Theory. Varian's (1990) firm theory analysis is extended from a single firm to multiple firms. This allows deriving the classical...

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

This paper uses a game-theoretic framework to suggest the fair value for information extracted via data mining and shared between two retail-market competitors. Neither competitor has a dominant position in that market. For mutual benefit, the two players each owning a privileged information set...

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...
