Envy-free pricing

Kind of fair item allocation

Envy-free pricing is a kind of fair item allocation. There is a single seller that owns some items, and a set of buyers who are interested in these items. The buyers have different valuations to the items, and they have a quasilinear utility function; this means that the utility an agent gains from a bundle of items equals the agent's value for the bundle minus the total price of items in the bundle. The seller should determine a price for each item, and sell the items to some of the buyers, such that there is no envy. Two kinds of envy are considered:Agent envy means that some agent assigns a higher utility to a bundle allocated to another agent. Market envy means that some agent assigns a higher utility to any bundle.
