Industrial Organization Society (IOS)
"The IOS was founded in the early 1970s to promote the study of real
competition in real markets. The focus is on the many forms and
processes of competition and market power, and on their effects on
prices, efficiency, innovation, and on broader social values such as
freedom of choice. The I.O.S. aims to promote research intended to be
useful in improving public policies, such as antitrust and regulation,
to improve market performance throughout the economy."
The IOS sponsors sessions at conferences, and it publishes the "Review
of Industrial Organization," which provides a forum for all types of
research in industrial organization but with particular emphasis on
ideas that can be verified by real evidence, including econometrics and
case studies.
