pDeveloping a strong theoretical base for research and practice in industrial relations and human resource management has to date remained a largely unfulfilled challenge. This pioneering volume helps close the theory gap by presenting contributions from fifteen leading scholars that develop and extend theoretical perspectives on work and the employment relationship. Subject areas covered include theories of employment relations systems, varieties of capitalism, the labor process, new institutional economics, individual work motivation, strategic human resource management, a theory of transaction costs and employment contracts, efficiency versus equity, and comparative industrial relations.p
