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.
