A meta-analytic review of opportunism in exchange relationships

The potential to engage in opportunism is a central theme in institutional economics, yet prior research has not quantitatively reviewed the role of opportunism in marketing research. This study uses meta-analytic techniques to synthesize research on opportunism conducted over the last quarter century. The analysis of 183 effect sizes extracted from 54 publications from the period 1982 to 2005 offers some support to extant channel theory. The research also indicates that the informant’s frame of reference and the research design significantly influence the observed effects. Implications of the findings and future research directions are discussed.
