This empirical study investigates the determination of the underwriting margins determination of Taiwanese ocean marine insurance during the period 1980-2013 that approaching by lagged periods with underwriting margins, short-term interest rates, policyholder’ s surplus to assets of capacity(K-SA)and policyholder’s surplus to net written premiums of capacity(K-SP). As above explanatory variables are created by the lag terms to determination the trend and influenced of underwriting margins. Under five regression models, we use the Hierarchical regression analysis to explore the determination of the underwriting margin of ocean marine insurance. The results provide evidence that empirical models support the hypothesis mentions the existence of underwriting margins margins which treated by information lags and reporting lags in Taiwan. Short-term interest rate is positively associated with underwriting margin by lag influence. The relations between K-SA indexe, K-SP indexe and the underwriting margins are statistical significantly different in marine cargo insurance case.
