Impact of organizational and buyer characteristics on the buying center

A mail survey of 200 organizational buyers was conducted to determine if the number of individuals in the buying center or the amount of perceived self-influence varied by organizational and buyer characteristics or by the type of purchase decision. The results of the study indicate that the type and size of the firm, as well as the buyer's educational level, affect both the number of individuals in the buying center and the amount of perceived self-influence of the organizational buyer. The results further indicate that the size of the buying center increases and the amount of perceived self-influence decreases as the purchase decision becomes more complex.
