Insurance Pricing Formula Based on Investment Theory LIU Hai-long, WU Chong-feng 2001, (3):  1-5.  Abstract ( 2189 )   PDF (862KB) ( 2848 )   Save Under the assumption that insurance companies are risk neutral,and using the theory of backward stochastic differential equation,the insurance pricing problem is studied in the framework of investment theory.At first,the linear forward-backward stochastic differential equation for insurance pricing is established.Then the insurance pricing formula based on the investment theory is obtained on the basis of the explicit solution of a special class of linear backward stochastic differential equation.Finally,an example is provided.
