It is known from the literature on uncertainty that in cases where individuals express a preference for a high win-probability bet over a bet with high winnings they nevertheless will bid more to obtain the bet with high winnings. We investigate whether a similar phenomenon applies in the...

Modelling Lorenz curves (LC) for stochastic dominance comparisons is central to the analysis of income distribution. It is conventional to use non-parametric statistics based on empirical income cumulants which are in the construction of LC and other related second-order dominance criteria....

An extensive micro data set matching firms, establishments and their employees, is used to study the determinants of earnings inequality in Portugal and its evolution from 1983 to 1992, with the Theil index, its decomposition, and the decomposition of its change as tools of analysis. A profile...

The paper presents an abstract definition of linear inequality concepts leading to linearly invariant inequality measures and characterizes the class of linear concepts completely. Two general methods of deriving ethical measures are proposed. They imply an Atkinson-Kolm-Sen index and a new dual...

We analyze the contracting structure in a moral hazard setting with several agents whereoutput is produced jointly and is the only contractible variable. Since the salary of each agentis a function of all agents efforts, a positive externality arises between them. This externalityis not...

This paper analyses the evolution of inequality and poverty in Brazil during the 1980s, using a large repeated cross-section household survey data set. We calculate standard scalar measures of inequality and poverty, together with decile means and decile shares. We also present percentile...

We contrast two approaches to the prediction of latent variables in the model of factor analysis. The likelihood statistic is a sufficient statistic for the unobservables when sampling arises from the exponential family of distributions. Linear predictors, on the other hand, can be obtained as...

Lorenz curves and associated tools for ranking income distributions are commonly estimated on the assumption that full, unbiased samples are available. However, it is common to find income and wealth distributions that are routinely censored or trimmed. We derive the sampling distribution for a...

Researchers in many fields of economics often compare distributions using some criterion or another of inequality, poverty or welfare. It is standard practice to base such comparative analysis on aggregated data. But will the results obtained be dependent on the degree of aggregation of the...

We examine the way in which across-the-board additions to incomes are perceived to change inequality. Using a questionnaire we investigate whether subjective inequality rankings correspond to the principle of scale-independence of translation-independence, or to some generalised concept of...
