VCG Payments for Portfolio Allocations in Online Advertising [PDF]

arXiv, 2015
Some online advertising offers pay only when an ad elicits a response. Randomness and uncertainty about response rates make showing those ads a risky investment for online publishers. Like financial investors, publishers can use portfolio allocation over multiple advertising offers to pursue revenue while controlling risk.

Unambiguous Efficiency of Random Allocations

In the problem of allocating indivisible objects via lottery, a social planner often knows only agents' ordinal preferences over objects, but not their complete preferences over lotteries. Such an informationally constrained planner cannot distinguish between different utility profiles that induce the same rankings over the objects. In this context, we

Scarce Resource Allocations That Rely On Machine Learning Should Be Randomized [PDF]

arXiv
Contrary to traditional deterministic notions of algorithmic fairness, this paper argues that fairly allocating scarce resources using machine learning often requires randomness. We address why, when, and how to randomize by proposing stochastic procedures that more adequately account for all of the claims that individuals have to allocations of social
