Project title

Dark side effect contagion

Project description

Business relationships are often a source of benefits for firms, but they can tip and unleash detrimental effects that diminish or even destroy relationship performance. This research project focuses on such dark side of business relationships and extends current understanding of dark side effects from a relationship portfolio and network perspective. A series of studies (including conceptual development, qualitative exploration, and quantitative examination) are conducted to articulate a concept of dark side effect contagion, advancing the understanding of how the dark side in one business relationship can influence other business relationships.
