To advance the study of comparative public policy there must be stronger methodological and theoretical descriptions and explanations of the development of policies and the actors, events, and contexts surrounding their development. Using the social construction and advocacy coalition frameworks, this study compares intergroup perceptions in adversarial and collaborative contexts in the Lake Tahoe Basin, United States. The results suggest one of the benefits of collaborative compared to adversarial contexts is improved intergroup perceptions. However, years may be needed for improved intergroup perceptions to take effect, and these effects may indicate the continuation of relative group positions.
