Equivalence Scales: Objective Methods. EASYPol Series 034

This analytical tool illustrates how to use objective methods to derive Equivalence scales. The focus will be on the Engel method, on the Rothbarth method and on the Utility-based methods. The main difference between these methods is that the first two are based on proxy variables for the household well-being, while the last set of methods is based on the consideration of the overall preferences revealed by consumers.
