NEGOTIATION • Liability claims are negotiated not “paid by the insurer”. • First party claims have payment regulations both good (Cooperation) and bad (Time Frames for Payment) re fraud. • Negotiation subject only to bad faith and unfair claim practice regulations • Two-person game: Adjusters and Claimant/Attorneys, but not suitable for game theory model. • Example in paper is Auto Bodily Injury Liability – Mass Data
NEGOTIATION • Claim Payment Components • Demands and Offers • Time Frames for Rounds • Anchoring and Adjusting • Offer/Demand Ratios • Settlements • Mass BI Data for 1996 AY • Statistical Modeling
Table 3 - 1 1 1996 data set - includes "Unknown Disability" claims and claims with a 1st Demand Amount 2 1996 data set - excludes 64 "Unknown Disability" claims
