Wage-Setting Measures: A Survey and Assessment

Wage setting has been one of the most heavily studied institutions in the field of comparative political economy over the past two decades, and quantitative measures of wage-setting arrangements have played a major role in this research. Yet the proliferation of such measures in recent years presents researchers with a sizable array from which to choose. In addition, some scholars are rather skeptical about the validity and/or reliability of these measures. This article offers a survey and assessment of fifteen wage-setting measures. It attempts to answer questions about (1) how these indicators differ from one another in conceptualization and measurement strategy; (2) which are the most valid and reliable; (3) the strengths and weaknesses of measures of wage centralization versus those of wage coordination; (4) particular countries or time periods for which there are noteworthy discrepancies in scoring; (5) how sensitive empirical findings are to the choice of wage-setting measure.
