Before revision: We study experimental design in large-scale stochastic systems with substantial uncertainty and structured cross-unit interference .
After revision: Classical approaches to experimental design assume that intervening on one unit does not affect other units. Recently, however, there has been considerable interest in settings where this non-interference assumption does not hold, e.g., when running experiments on supply-side incentives on a ride-sharing platform or subsidies in an energy marketplace. In this paper, we introduce a new approach to experimental design in large-scale stochastic systems with substantial uncertainty and structured cross-unit interference .
