In 1905, Max O. Lorenz suggested a simple method of measuring the concentration of wealth, based on the visual representation of income distribution. The Lorenz curve is now very popular and can be considered as canonical. However, the path leading from Lorenz's original work to contemporary...

This paper proposes an experiment about the attitude toward probabilities on a population of portfolio managers. Its aim is to check whether or not portfolio managers are neutral toward probabilities. Meanwhile, it presents a experimental protocole that highlights an inconsistency between two...

The linear plus exponential utility function has received increasing attention of late as a particularly attractive family for evaluating additive gambles for wealth. In addition to its ability to reflect increasing appreciation for money, risk aversion, and decreasing risk aversion, it is...

In modern society the income distribution is one of the major problems. Usually, it is considered that a severe polarisation in matter of income per capita could have a major negative impact on the general process of economic development. This study is focussing on estimating dynamics of some...

Similar looking Lorenz Curves can imply very different income density functions and potentially lead to wrong policy implications regarding inequality. This paper derives a relation between a Lorenz Curve and the modality of its underlying income density: Given a parametric Lorenz Curve, it is...
