63 Notions of institutional complementarity were introduced in economics to analyze the fit between organizational structure and work practices within firms, e.g., Chandler, Alfred Dupont, Strategy and Structure (Cambridge: MIT Press, 1962)Google Scholar; Milgrom, Paul and Roberts, John, “Complementarities and Fit: Strategy, Structure, and Organizational Change in Manufacturing,” Journal of Accounting and Economics 19 (March-May 1995), 179–208CrossRefGoogle Scholar. In comparative political economy, notions of complementarity play an important role of the varieties of capitalism literature, especially Aoki, Masahiko, “The Contingent Governance of Teams: Analysis of Institutional Complementarity,” International Economic Review 33 (August 1994), 657–76CrossRefGoogle Scholar; Amable, Bruno, Ernst, Ekkehard, and Palombarini, Stefano, “How Do Financial Markets Affect Industrial Relations? An Institutional Complementarities Approach” (Manuscript, University of Paris, August 2001Google Scholar, http://pythie.cepremap.ens.fr/~amable/instcomp.pdf, accessed June 30, 2003); and Peter Hall and Daniel Gingerich, “Varieties of Capitalism and Institutional Complementarities in the Macroeconomy” (Paper presented at the International Seminar on Institutional Complementarities and Dynamics of Economic Systems, Universite de Paris, April 5–6, 2002). None of these, however, considers the implications of institutional complementarities for the ability of actors at a lower level to affect coordination efficiently at a higher level of aggregation.
