James A. Levinsohn

The work. The L in BLP, and separately the Levinsohn-Petrin method for estimating production functions when firms pick inputs in response to shocks the researcher cannot see.

The case for. Two methods that thousands of papers cite, one on the demand side and one on the supply side of the same problem.

The case against. He has spent the last decade running the Jackson School at Yale rather than publishing, and if the committee rewards BLP the story will center on Berry and Pakes.

The KmikeyM angle. Levinsohn-Petrin corrects for the fact that a firm knows its own productivity before the analyst does. Mike knows his before his shareholders do, and gets priced anyway.
