In the March 1988 issue of this Review, Virginia Gray and David Lowery presented a respecification of Mancur Olson's model of economic growth and tested the revised model with U.S. state data. A special feature of the Gray-Lowery analysis is its more thorough measurement of interest group effects. These investigators found interest group influences quite different from those anticipated by Olson's model. Paul Brace and Youssef Cohen argue that the Gray-Lowery model misspecifies the determinants of state economic growth, overstating the role of interest group size and failing to incorporate crucial exogenous variables. Gray and Lowery join the issue and defend their specification.
