From Fog to Smog: the Value of Pollution Information

Demand Analysis with Many Prices

Recognizing that the price that consumers face for a given good is likely to vary at any point in time, Victor Chernozhukov, Jerry A. Hausman, and Whitney K. Newey apply machine learning tools to develop new estimators of both demand elasticities and consumer surplus. Applied to household purchases of soft drinks, they find that demand elasticities tend to be smaller in panel than in cross-sectional data.
