 Excellent surveys of the unidimensional part of the theory include: Chakravarty (1990, 2009), Cowell (2000), Dutta (2002), Lambert (1989), Sen and Foster (1997), Silber (1999). The multidimensional approach is surveyed or discussed in Weymark (2006), Chakravarty (2009), Decancq and Lugo (2013), Aaberge and Brandolini (2015), Alkire et al. (2015), Duclos and Tiberti (2016). The link between inequality and poverty measurement and welfare economics is discussed in Decancq et al. (2015) and in several chapters of Adler and Fleurbaey (2016). For a comprehensive handbook on economic inequality, see Atkinson and Bourguignon (2000, 2015).
