The impact of human resource management (HRM) policies and practices on firm performance is an important topic in the fields of human resource management, industrial relations, and industrial and organizational psychology (Boudreau, 1991; Jones & Wright, 1992; Kleiner, 1990). An increasing body of work contains the argument that the use of High Performance Work Practices, including comprehensive employee recruitment and selection procedures, incentive compensation and performance management systems, and extensive employee involvement and training, can improve the knowledge, skills, and abilities of a firm's current and potential employees, increase their motivation, reduce shirking, and enhance retention of quality employees while encouraging nonperformers to leave the firm (Jones & Wright, 1992; U.S. Department of Labor, 1993).
