Professor Garud Iyengar (Industrial Engineering and Operations Research Department at Columbia University): Shapley Meets Uniform: An Axiomatic Framework for Attribution in Online Advertising
Abstract
A central challenge in online advertising is attribution, namely, assessing the contribution of individual ads to product purchase. We develop an axiomatic framework for attribution in online advertising. Under a Markovian model for user behavior, we illustrate limitations of existing heuristics and propose a novel framework motivated by causality and game theory. Furthermore, we establish that our framework coincides with an adjusted “unique-uniform” attribution scheme. This scheme is efficiently implementable and can be interpreted as a correction to the commonly used uniform attribution scheme. We supplement our theory with numerical experiments inspired by a real-world dataset.
Joint work with Raghav Singal (alum of MIE, U Toronto), Omar Besbes, Antoine Desir, and Vineet Goyal.
