Necessary Versus Sufficient Claims Data

This data brief compares membership characteristics and health care service prices in non-ERISA and ERISA populations. The results suggest that non-ERISA data may be sufficient for policy relevant analyses, even when ERISA data is not available

Macro vs. Micro Methods in Non-Life Claims Reserving (an Econometric Perspective)

Traditionally, actuaries have used run-off triangles to estimate reserve ("macro" models, on agregated data). But it is possible to model payments related to individual claims. If those models provide similar estimations, we investigate uncertainty related to reserves, with "macro" and "micro" models. We study theoretical properties of econometric models (Gaussian, Poisson and quasi-Poisson) on individual data, and clustered data. Finally, application on claims reserving are considered
