In a cost-sharing problem, several participants with unknown preferences vie to receive some good or service, and each possible outcome has a known cost. A cost-sharing mechanism is a protocol that decides which participants are allocated a good and at what prices. Three desirable properties of a cost-sharing mechanism are: incentive-compatibility, meaning that participants are motivated to bid their true private value for receiving the good; budget-balance, meaning that the mechanism recovers…

Trade-offs in cost sharing
In a cost-sharing problem, several participants with unknown preferences vie to receive some good or service, and each possible outcome has a known cost. A cost-sharing mechanism is a protocol that…
Approximately Efficient Cost Sharing via Double Auctions∗
A well-known result in the cost-sharing literature asserts the non-existence of mechanisms that are strategyproof, (weakly) budget balanced, and economically efficient, even when budget balance and…

Quantifying Inefficiency of Fair Cost-Sharing Mechanisms for Sharing Economy
TLDR
The inefficiency of distributed decision-making processes under a cost-sharing mechanism by the strong price of anarchy is quantified, showing that the SPoA for equal-split, proportional- split, and usage-based cost sharing (under certain conditions) is only moderate inefficiency.
To Be or Not to Be ( Served ) : Cost Sharing Without Indifferences ∗
In a cost-sharing problem, finitely many players have unknown valuations for some service, and a mechanism is sought for determining which players to serve and how to distribute the incurred cost. An…
Combinatorial Cost Sharing
TLDR
The Potential Mechanism is presented -- a combination of the VCG mechanism and a well-known tool from the theory of cooperative games: Hart and Mas-Colell's potential function, a dominant strategy mechanism that always covers the incurred cost.
Is Shapley Cost Sharing Optimal ? ∗ ( For the special issue in honor of Lloyd Shapley )
TLDR
For the public excludable good problem, the Shapley value mechanism minimizes the worst-case efficiency loss over all truthful, deterministic, and budget-balanced mechanisms that satisfy equal treatment.
Cost Sharing in Two-Sided Markets
TLDR
This framework designs mechanisms that are efficient, ex-ante budget-balanced,Ex-ante individually rational, dominant strategy incentive compatible, and ex-antes in the core (a natural generalization of the core that is defined here).
Network Cost-Sharing without Anonymity
TLDR
These primary results are tight bounds on the cost of strong Nash equilibria and potential function minimizers in network cost-sharing games with nonanonymous cost functions, parameterized by the set C of allowable submodular cost functions.

New trade-offs in cost-sharing mechanisms
TLDR
It is shown that incentive-compatibility, budget-balance, and approximate efficiency are simultaneously achievable for a wide range of cost functions, where efficiency is measured using the social cost---the sum of the incurred service cost and the excluded valuations.
Optimal Efficiency Guarantees for Network Design Mechanisms
TLDR
This work proves for the first time that approximate budget-balance and efficiency are simultaneously possible in a cost-sharing problem and proves a new, optimal lower bound on the approximate efficiency achievable by the wide and natural class of "Moulin mechanisms".
Limitations of cross-monotonic cost sharing schemes
TLDR
This paper investigates the limitations imposed by the cross-monotonicity property on cost-sharing schemes for several combinatorial optimization games including edge cover, vertex cover, set cover, metric facility location, maximum flow, arborescence packing, and maximum matching, and develops a novel technique based on the probabilistic method for proving upper bounds on the budget-balance factor ofCross-monotonic cost sharing schemes.
Incremental cost sharing: Characterization by coalition strategy-proofness
Abstract. Each one of n users consumes an idiosyncratic commodity produced in indivisible units. The n commodities are jointly produced by a central facility and total cost must be shared by the…
Strategyproof cost-sharing Mechanisms for Set Cover and Facility Location Problems
TLDR
This paper obtains strategyproof cost allocations for two fundamental games whose underlying optimization problems are NP-hard, the set cover game and the facility location game and obtains a strategyproof mechanism based on a constant factor approximation algorithm.
The Price of Stability for Network Design with Fair Cost Allocation
TLDR
It is established that the fair cost allocation protocol is in fact a useful mechanism for inducing strategic behavior to form near-optimal equilibria, and its results are extended to cases in which users are seeking to balance network design costs with latencies in the constructed network.

Cost-Sharing Mechanisms for Network Design
TLDR
A single source network design problem from a game-theoretic perspective and shows how to use a variant of this method to develop an approximately budget-balanced and group strategyproof cost-sharing method for the problem.
Cost-Sharing Mechanisms for Network Design
TLDR
The algorithm is conceptually simpler than the previous such cost-sharing method due to Pál and Tardos, and improves the previously-known approximation factor of 15 to 4.6.
