Abstract

This article follows a previous study on insurance fraud in the Quebec automobile insurance industry (Dionne and Belhadji, 1996). Results from that research showed that 3 to 6,4% of all claim payments (excluding those for "glass damage only") contained fraud, representing 28 to 61 million dollars in 1994-1995. This evaluation was a minimum since it was limited to observed fraud only. In this paper, we apply a statistical method to estimate the total fraud level in the industry for the same period. Our results show a multiplicative factor of 3,4% of fraudulent files found in Dionne and Belhadji, which means that total fraud payments ranged from 96,2 to 208,4 million dollars in 1994-1995. Our Best Guest Estimator roughly a 10% fraud rate or about 113,5 million dollars.
