This paper investigates the multiperiod asset-liability management problem with quadratic transaction costs. Under the mean-variance criteria, we construct tractability models with/without the riskless asset and obtain the pre-commitment and time-consistent investment strategies through the application of embedding scheme and backward induction approach, respectively. In addition, some conclusions in the existing literatures can be regarded as the degenerated cases under our setting. Finally, the numerical simulations are given to show the difference of frontiers derived by different strategies. Also, some interesting findings on the impact of quadratic transaction cost parameters on efficient frontiers are discussed. [ABSTRACT FROM AUTHOR]

In the big data era, increasing financial support for the marine economy and vigorously developing blue finance have a strong sense of urgency and historical mission, which need a larger macro vision and a more forward-looking strategic layout. Blue finance is related to China's economic and financial security. We must seize the development opportunities of blue finance in the new era and set up a systematic financial thinking of big countries. Only adopting the strategic thinking of innovation and development, can we support the marine economy in the big data era. [ABSTRACT FROM AUTHOR]
