# Mean-variance Optimal Reinsurance-investment Strategy in Continuous Time

• Received: 29 June 2017 Accepted: 19 September 2017 Published: 12 October 2017
• In this paper, Lagrange method is used to solve the continuous-time mean-variance reinsurance-investment problem. Proportional reinsurance, multiple risky assets and risk-free asset are considered synthetically in the optimal strategy for insurers. By solving the backward stochastic differential equation for the Lagrange multiplier, we get the mean-variance optimal reinsurance-investment strategy and its effective frontier in explicit forms.
