Example • $2,500,000 premiums written Current year limited loss ratio is 30% • Contingent commission = $2,500,000 * 0.0192 = $48,000 2007 ARIA Meeting, Quebec City
Relevant Literature – Market Cycles • Rational Expectation Theory: Perfect market - Cummins and Outreville (1987) • Capacity Constraint Theory: Not perfect market - Winter(1988, 1991a, 1994) - Gron (1994) - Cummins and Danzon(1992) - Doherty and Garven(1995) • Risky Debt Theory: Insurer’s default risk - Harrington et. al. (1988,1994, 2004, 2005) - Cummins and Danzon(1997) 2007 ARIA Meeting, Quebec City
Harrington (2004 & 2005) • Proxy: Loss ratio development = Developed loss ratios - Originally reported loss ratios • Argument: - Premium growth in the soft market is positively correlated with loss ratio development - Excessive price cuts in the preceding soft market are associated with upward claims costs development in the subsequent hard market Trigger the formation of hard market ! 2007 ARIA Meeting, Quebec City
