On today’s online social networks (OSNs), users need to reveal their content and their sharing patterns to a central provider. Though there are proposals for decentralized OSNs to protect user privacy, they have paid scant attention to optimizing the cost borne by users or hiding their sharing patterns.

The manufacturer provides a common product to the retailers at the same wholesale price. Both retailers add their own values to the product and distribute it to consumers. Factors such as retail prices, values added to the product, and local ad...

We show that serial cost sharing for heterogeneous goods [4], and a large number of other cost sharing mechanisms, have the same strong strategic properties as serial cost sharing for homogenous goods [10], including uniqueness of the Nash equilibrium for all utility profiles and cost functions, dominance solvability, solvability in overwhelmed actions, and robustness to coalitional deviations....
