Mainstream economics traditionally restricts the analysis of the labor market to purely monetary factors, such as earnings, leaving aside many other characteristics which might affect the desirability of certain jobs. By contrast, this original book aims to explore the alternatives and problems faced by researchers in quantifying and measuring a broader notion of job quality. The main objective is to analyze the different approaches to measurement and to analyze both the advantages and disadvantages of the various methods within a European context. Specifically, the book presents a unique new index of job quality and applies it to the EU Member States. The index proves particularly useful to measure the differences in job quality by country, occupation, gender and age. Based on solid theory and data, this book will prove essential for postgraduate students, researchers and academics of labor economics, sociology, industrial relations, and European studies as it presents a coherent discussion of the concept and components of job quality, and of the difficulties of measuring it. The book also proposes a new aggregate index of job quality that can contribute to the evaluation of European employment policies and performance that will appeal to European policy circles.
