Abstract
In order to rate intermediaries, Detralytics has developed a credibility model separating pure randomness from structural differences in loss ratios. The output results in a reliability index quantifying the confidence one can place on underwriting experience for a particular intermediary (based on the credibility coefficient) and a performance index assessing the quality of intermediary’s production (based on the credibility predictor of individual random effects). In this note, an elementary approach is proposed, treating broker’s efficiency level as a fixed effect (rather than a random effect in credibility). This provides the actuary with a preliminary ranking pointing to the ineffective intermediaries.
