Research perspectives from role theory are examined with a large sample of purchasing professionals in an effort to increase understanding of industrial buyer behavior and the buying environment. An integrative model of the antecedents and consequences of role stress fits the data well. The results suggest that an awareness of the nature and influence of role stress in the buying context can be of value to marketing professionals, especially sales representatives and marketing/product managers.

Manifest channel conflict is operationalized in terms of the frequency and intensity of disagreements between channel members and the importance of the issues about which they disagree. Six different multiple-item unidimensional measures including from one to all three of these components are evaluated with respect to reliability and validity with a sample of automobile dealers. The measure combining frequency, intensity, and importance multiplicatively is judged superior to the others.

It has long been a belief that marketing has a positive effect on quality of life by delivering material well-being. Furthernore, many marketing scholars urge that greater emphasis be placed on marketing in developing countries to improve the quality of life. This conventional wisdom has not been investigated empirically because of inadequate conceptualizations of the relationship between marketing and the quality of life and because of the lack of necessary measurements. In the present study, these conceptualizations and measurements have been supplied, and a model utilizing a satisfaction/dissatisfaction framework has been developed and tested. According to the model, an individual's satisfaction with different domains of life (for example, work life, material possessions) has a significant positive effect on his or her overall satisfaction with life (quality of life). Data obtained from residents of the developing country of Thailand were used to test the hypotheses. Results of the study show that satisfaction with three domains-Family Life, Material Possessions, and Self-development-has a significant positive impact on overall life satisfaction. Additional findings and implications for government, business, and marketing researchers are presented, along with directions for future research.
