Robust Signal Maximization in Spillover Experiments
Kirill Borusyak, Peter Hull, Evan Munro
We study the optimal design and analysis of experiments for estimating spillover effects. Assuming a known (e.g., linear) exposure mapping, we characterize the treatment-assignment…
Leniency Designs: An Operator's Manual
Paul Goldsmith-Pinkham, Peter Hull, Michal Kolesár
We develop a step-by-step guide to leniency (a.k.a. judge or examiner instrument) designs, drawing on recent econometric literatures. The unbiased jackknife instrumental variables…
Nonparametric Identification of Demand without Exogenous Product Characteristics
Kirill Borusyak, Jiafeng Chen, Peter Hull +1
We study identification of differentiated product demand from market-level data when product characteristics can be endogenous. Past work suggests nonparametric identification may…
Long-Term Causal Inference with Many Noisy Proxies
Apoorva Lal, Guido Imbens, Peter Hull
We propose a method for estimating long-term treatment effects with many short-term proxy outcomes: a central challenge when experimenting on digital platforms. We formalize this c…
Estimating Demand with Recentered Instruments
Kirill Borusyak, Mauricio Caceres Bravo, Peter Hull
We develop a new approach to estimating flexible demand models with exogenous supply-side shocks. Our approach avoids conventional assumptions of exogenous product characteristics,…
