Log-concave functions and transformations thereof

Theoretical Economics 2025-12-17 v2

Abstract

I summarize Bagnoli and Bergstrom (2005)'s review on log-concave functions, make several corrections, and augment the discussion with further results that can be useful in obtaining monotone hazard rate. I also provide an application of monopoly pricing, where strict logconcavity of demand curve implies strict concavity of the revenue function.
