Successful strategy execution depends on the HRM system effectively developing and motivating its human capital and making sure that structures and processes permit it to be put to productive use. In this chapter we discuss methodological challenges in doing empirical research on HRM and effectiveness in the field of comparative HRM. Some methodological issues we discuss here will be specific to comparative HRM research, while others apply to HRM research in both single-nation and comparative contexts. It is widely recognised that cross-country differences are important for the management of people in organisations. As highlighted by new institutionalists (Wood et al., this volume), countries differ in regulations, institutions, and culture (Brewster, 1999; Brewster et al., 2004; Dowling et al., 2008; Evans et al., 2002; Hofstede, 1980, 2001; Kostova, 1999). While new institutionalism covers a range of fairly heterogeneous approaches, the basic premise is that advances in technology and communications lead to less diversification globally (Wood et al., in this volume), a process called isomorphism (Kostova & Roth, 2002). Thus, the institutionalist approach stresses the tendency of organisations to respond to their environment in ways that signal conformity and enhance legitimacy (DiMaggio & Powell,...
