"Optimal investment strategies for defined benefit pension plans under funding ratio constraint" (2015) by J. Chen, J. Lian, and Y. Zhou. This paper presents optimal investment strategies for defined benefit pension plans that are subject to a funding ratio constraint.
"Optimal investment strategies for defined contribution pension plans under inflation risk" (2015) by Y. Li and J. Zhang. This paper proposes optimal investment strategies for defined contribution pension plans that take into account inflation risk.
"Optimal investment strategies for defined benefit pension plans under stochastic interest rates" (2014) by J. Chen, J. Lian, and Y. Zhou. This paper presents optimal investment strategies for defined benefit pension plans that take into account stochastic interest rates.

The main contributions of these papers are the development of optimal investment strategies for different types of pension plans under various risk factors such as inflation, stochastic interest rates, mortality rates, and funding ratio constraints. These strategies provide guidance for pension fund managers to make informed investment decisions that maximize returns while minimizing risks
