Currencies of exchange and global LMX: How they affect employee task performance and extra-role performance.

Two studies are presented in this research to integrate the unidimensional and multidimensional perspective of leader-member exchange (LMX). We posit that the dimensions of multidimensional LMX (LMX-MDM) are the exchange currencies of global LMX and investigate their joint effects on task performance and extra-role behaviors of employees. The results from Study One indicate that the affect, loyalty, contribution, and professional respect dimension of LMX-MDM influence overall level of leader-member relationship quality, and global LMX is positively related to task performance as well as organizational citizenship behaviors (OCB). Study Two partially replicates the results in Study One and demonstrates that global LMX is also associated with contextual performance of employees. Limitations and future research on LMX are discussed. [ABSTRACT FROM AUTHOR]
