Research Interests

Mahle concentrates his research and scholarship on standards for admissibility of economics expert testimony in US Federal Courts. He just completed two major projects in that area.

He has two new avenues of scholarship. The first is a new application of a classical legal principle that is at the center of the foundations of Law & economics called the Learned Hand Rule that he believes has application to police shootings of citizens.
