This volume describes a wide range of alternative methods of constructing qualitative indicators of labor standards. It provides a unique comparative critique of strengths and limitations of different methods of constructing qualitative indicators of labor standards with reference to different applications. Measuring compliance with labor standards is an undertaking intrinsically fraught with difficulty. For there are a number of possible sources of measurement error, both random and non-random, that are unique to such indicators, on top of those that affect qualitative and quantitative indicators alike. The growing use of qualitative indicators of labor standards thus raises a number of questions about comparative methods of construction as well as the appropriateness of particular methods for particular applications. This addresses these and other related questions.
