Leader–member exchange, shared values, and performance: Agreement and levels of analysis do matter

In this study, we first investigate the levels of analysis at which leader–member exchange (LMX) operates; second, we examine the nature of the LMX–performance relationship when a superior and a subordinate agree as compared to disagree concerning the quality of their exchange; third, we test the effect of superior–subordinate agreement about work values on the LMX–performance relationship; and fourth, we simultaneously consider the effects of LMX agreement–disagreement and values agreement–disagreement on the LMX–performance relationship. Our findings indicate that LMX operates primarily at the independent dyad level of analysis. We also found that LMX and performance are most strongly related and display the strongest dyadic-level effects when superior and subordinate assessments of LMX and values are in agreement.
