Key informant reports from both sides of a set of wholesaler-retailer dyads are analyzed to investigate the convergent and discriminant validity of the measures. These measures, derived from a political economy model, describe the structural form and collective sentiments within the dyadic interaction. The results indicate that the structural form measures have convergent and discriminant validity. However, the sentiments variables fail to show adequate validity. The methodological and theoretical implications of the results are assessed.
This paper presents a unifying framework for the analysis of distribution channels which encompasses both economic and sociopolitical determinants of channel member behavior and provides a suitable departure point for comparative work. The framework integrates present approaches to the study of marketing channels and provides an essential, but heretofore missing, basis for comprehensive empirical research in the area.
