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.
