Abstract

This paper describes the community impact assessment conducted after Concorde operations were initiated at Dulles International Airport. Problems in the design and conduct of this study that make causal interpretations implausible are discussed. The present authors report an improved design to eliminate these problems as well as increase the external validity of the results. A discussion of how the careful implementation of quasiexperimental designs allows for treatment-related causal interpretations to be made is also included. Finally, it is emphasized that practical application of these data make it possible to improve the implementation of the treatment in communities receiving it at a later date.
