These economists' use of econometric methods, and their views on the value of these methods, are documented and compared with the academic approach to applied econometric work, as reported in the scholarly literature. The evidence on the nine indicators supports the existence of a state of separation. The paper points to some undesirable consequences of separation and concludes with practical ideas on what should be done about it. There are lessons in the findings of this study for the future of other quantitative disciplines that are widely practised in government, business and industry.
