讲座题目一：Dynamic hedging of longevity risk: the effect of trading frequency
摘要：This paper investigates dynamic hedging strategies for pension and annuity liabilities that are exposed to longevity risk. In particular, we consider a hedger who wishes to minimize the variance of her hedging error using index-based longevity-linked derivatives. To cope with the fact that liquidity of longevity-linked derivatives is still limited, we consider a liquidity constrained case where the hedger can only trade longevity-linked derivatives at a frequency lower than other assets. Time-consistent, closed-form solutions of optimal hedging strategies are obtained under a forward mortality framework. In the numerical illustration, we show that lowering the trading of the longevity-linked derivatives to a 2-year frequency only leads to a slight loss of the hedging performance. Moreover, even when the longevity-linked derivatives are traded at a very low (5-year) frequency, dynamic hedging strategies still significantly outperform the static one.

讲座题目二：Securitization in the Presence of Systemic Risk and Catastrophic Events
摘要:Systemic risk has been sited as one of the most important reasons that cause agricultural insurance market failure. Traditional agricultural insurance also suffers from the difficulty of information asymmetry, including moral hazard and adverse selection. Therefore, different stakeholders including reinsurers, financial markets, as well as governments are seeking capital innovations, such as securitization, as critical supplementary components in the management of catastrophes and systemic risk. In this talk, we will discuss developing innovative index-based insurance based on satellite-sensed data. In particular, we will focus on the induced basis risk, which is the most essential challenge for a feasible and validated index insurance program.
