This paper describes an approach for conducting empirical research into three interrelated questions that are fundamental to the field of organizational economics: 1.Why do firms in the same industry adopt different management practices?2.Does the adoption of a new management practice raise productivity? 3.If so, why does the new management practice raise productivity?This research approach, which we term insider econometrics, addresses these questions by combining insights from industry insiders with rigorous econometric tests about the adoption and productivity effects of new management practices using rich industry-specific data. Understanding the selectivity in the adoption and coverage of different management practices within a single industry is central to this empirical research methodology. The paper considers a number of studies to illustrate persuasive features of insider econometric research and summarizes a number of themes emerging from this line of research"--National Bureau of Economic Research web site.
