报告摘要1:

Abstract1: Since the crisis in 2007–2008, the stability and resilience analysis of a financial network has become a very important and active research areas in economics and finance. In this talk, we give a basic introduction to new optimization models and theory to address the following two critical issues:

Vulnerability analysis of a financial network when only limited information of the network is available and the assets are subject to market shocks;

Identification of the least (most) stable network structure for fixed assets and exploration of cascading failure in the identified least stable network;

Specifically, we explore the effect of asset inequality on the stability of the network to identify the most vulnerable asset distribution, and develop new optimization model and techniques to identify the least and most stable network structure. We will characterize the network structure corresponding to the identified least and most stable network structure, and demonstrate the domino effect of bankruptcy in the least stable network. Numerical experiments will be reported to verify the theoretical results.

报告摘要2:

Abstract2: Since the crisis in 2007–2008, the control and mitigation of systemic risk in financial networks has become one of the most important research areas in economics and finance. In this talk, we give a basic introduction to various models and policies in systemic risk mitigation. These include the rescue consortium by Rogers and Veraat, the bail-ins and bail-outs model by Bernard et al., the mixed integer linear optimization model for optimal bailout policy with a fixed budget. If times allows, we will also discuss how to apply popular strategies such as merging and acquisition to mitigate the systemic risk in financial networks.
