Problems of using grouped DMUs for efficiency measurement: Monte Carlo experiments, empirical dimension, and a correction procedure
Brümmer, Bernhard; Thiele, Holger D. - 1999
This paper explores the consequences for parametric and non-parametric efficiency levels and rankings when using grouped instead of individual Decision Making Units (DMU). The bias results due to the differences of the grouped DMUs frontier compared to the individual DMUs frontier. Monte Carlo...

Recovering income distributions from aggregated data via micro-simulations
Moral-Arce, Ignacio; Heras Perez, Antonio de las; … - In: Spanish journal of statistics 1 (2019) 1, pp. 13-29
For the studies of wealth, inequality and poverty, the analysis of income distribution of the individuals is a crucial issue. In practice, however, only aggregated data are available, either in groups or as a few quantiles of the distribution. To perform counterfactual exercises, it is desirable...
