INTRODUCTION
Recently, one of us gave a workshop on how to conduct meta-analyses. The workshop was attended by participants from a number of different disciplines, including economics, finance, psychology, management, and health sciences. During the course of the workshop, it became apparent that different disciplines conduct meta-analyses differently. While there is a vague awareness that this is the case, we are unaware of any attempts to quantify those differences.

Fixed effects estimators are often used when researchers are concerned about omitted variable bias due to unobserved, time-invariant variables.
