This paper analyzes wage decomposition methodology in the context of panel data sample selection embedded in a correlated random effects setting. Identification issues unique to panel data are examined for their implications for wage decompositions. As an empirical example, we apply our...

We apply fuzzy sets theory to measure the extent of overweight in Luxembourg. This methodology permits to differentiate between mild or severe forms of overweight and to identify the sub-populations which contribute most to global overweight. The application to residents of Luxembourg shows that...

Using harmonized wealth data and a novel decomposition approach, we show that cohort effects exist in the income pro?les of asset and debt portfolios for a sample of European countries and the U.S. We ?nd that observable characteristics explain a sizable portion of the wealth participation gap...

Population processes are expected to contribute to global income inequality but so far, studies have mostly documented the contributions of changing population size. Such studies typically decompose global inequality trends into population size vs. income effects. We expand decomposition to...

Opportunity egalitarians support rich-to-poor redistribution whenever this allows for the compensation of income disparities due to non-responsible choices (circum- stances). In this paper we investigate the measurement of opportunity inequality within Roemer's (1993) pragmatic theory where...
