Zusammenfassung: 
This paper explores, in the context of the Atkinson inequality measure, attempts to make interpretations of orders of magnitude transparent. One suggestion is that the analogy of sharing a cake among a very small number of people provides a useful intuitive description for people who want some idea of what an inequality measure ‘actually means'. In contrast with the Gini measure, for which a simple ‘cake-sharing' result is available, the Atkinson measure requires a nonlinear equation to be solved. Comparisons of ‘excess shares' (the share obtained by the richer person in excess of the arithmetic mean) for a range of assumptions are provided. The implications for the ‘leaky bucket' experiments are also examined. An additional approach is to obtain the ‘pivotal income', above which a small increase for any individual increases inequality. The properties of this measure for the Atkinson index are also explored.
