Asset specificity's impact on outsourcing relationship performance: A disaggregated analysis by buyer–supplier asset specificity dimensions

Using hierarchical regression analysis on a sample of UK service firms, this study tests the impact of asset specificity on outsourcing relationship performance within a disaggregated methodological framework that allows to discern the specific effects of various buyers and suppliers' individual dimensions of asset specific investments. The results indicate that the impact of asset specific investments on outsourcing relationship performance varies according to the particular specificity dimension examined. While all statistically significant dimensions of buyers' asset specificity have a negative impact on relationship satisfaction, suppliers' human and dedicated asset specific investments exert a positive and significant influence. The results also show that, in three interaction instances, reciprocal specific investments are positively associated with outsourcing relationship performance. These findings have profound theoretical and methodological implications.
