We provide a new technique to derive group strategyproof mechanisms for the cost-sharing problem. Our technique is simpler and provably more powerful than the existing one based on so called crossmonotonic cost-sharing methods given by Moulin and Shenker [1997]. Indeed, our method yields the first polynomial-time mechanism for the Steiner tree game which is group strategyproof, budget balance a...

We study mechanisms for cooperative cost-sharing games satisfying: voluntary participation (i.e., no user is forced to pay more her valuation of the service), consumer sovereignty (i.e, every user can get the service if her valuation is large enough), no positive transfer (i.e., no user receives money from the mechanism), budget balance (i.e., the total amount of money that users pay is equal t...

The Integrated Healthcare Association is coordinating an episode of care payment initiative involving prominent health plans, hospital systems, and physicians organizations in California. he fragmentation of payment methods undermines efficiency and quality of care due to its effects on both providers and consumers. This effect is especially pronounced when considering high-cost surgical proced...

Advances in information technology increasingly allow firms to identify expensive, high-cost customers, who are not only individually less profitable for firms but also raise the average marginal cost incurred by firms and thus impose a negative externality on inexpensive customers. Should competing firms share information that identifies such customers? The answer to this question has importan...

BACKGROUND: While increases in prescription drug spending have moderated in recent years, drug spending is still a concern among managed care organizations and health plan administrators. In order to minimize cost increases from year to year, many health care plans have shifted more of the cost of medications to the member-consumer. Coinsurance, a benefit design in which the patient pays a perc...

Considering that the demand for fresh agricultural products is affected by product freshness and price, a two-level supply chain decision model consisting of risk-neutral supplier risk-averse retailer constructed. In order to increase consumer products, will make appropriate efforts preserve products. The optimal fresh-keeping effort level pricing under centralized decision-making decentralized...

Reference pricing in health insurance creates incentives for patients to select for nonemergency services providers that charge relatively low prices and still offer high quality of care. It changes the "choice architecture" by offering standard coverage if the patient chooses cost-effective providers but requires considerable consumer cost sharing if more expensive alternatives are selected. T...

the present study was focused on supply chain analysis of fresh guava in order to evaluate existing marketing supply chains (sc1: producer - consumer, sc2: producer - retailer - consumer, sc3: producer - commission agent - retailer - consumer, sc4: producer - commission agent - wholesaler - retailer - consumer) for two variety (allahabad safeda and apple guava) of guava. the gross marketing pri...
