On aggregating Benefit of the Doubt composite indicators

In this short communication, I propose a procedure to aggregate individual composite indicators (CIs) into a group CI (e.g., aggregate CI for a group of countries) that is based on the work of Färe and Zelenyuk (2003) that was originally presented in the efficiency measurement literature. It is shown that the implementation of the aggregation procedure into the CI-context is rather straightforward. To illustrate the procedure in the CI-setting, an aggregate CI for human development for the global EU-region is computed using the EU Member States' HDI sub-indicators.
