This chapter is devoted to a presentation and discussion of the three main approaches to measuring equivalence scales which are the expert approach, the economic approach, and the survey approach. Most attention will be paid to the economic and to the survey approach since both are applied in this thesis. Already here, we would like to point out that equivalence scales derived in previous studies now and then are of dubious value. Thus, the reader should not think of typing errors if she/he finds that equivalence scales for the same household type lie in a rather wide range.
