This three-day workshop covers the Berry-Levinsohn-Pakes (BLP) approach to estimating the statistical relationship between product sales and product characteristics such as prices. As the foundational approach for differentiated products demand estimation in the industrial organization literature, BLP is used by academics, antitrust regulators, and industry professionals to shed light on difficult questions.

• “What is the value of a new good?”
• “Will a merger hurt consumers?”
• “Should we change prices?”

Through a running empirical example, the workshop will use a series of coding exercises to build up practical knowledge for studying these types of questions and more.

This is one of our advanced courses. These courses are designed assuming a solid foundation in the basics of economic models and instrumental variables. Scott's Causal Inference (Part 1) covers instrumental variables.
