About the Project
Systemic risk (SR) is considered as the risk of collapse of an entire financial system, which has played a significant role in explaining the recent financial turmoils from the insurance and financial industries. In this project, we first employ a statistical procedure in analyzing market price data, with a focus in empirical studies on the heavy-tailedness of tail risks, extreme dependence across financial markets, and joint expected shortfall on financial risks. Based on the results of empirical studies, we consider the asymptotic behavior of the SR for portfolio losses in the model which allows for heavy-tailed primary losses and are equipped with a wide type of dependence structures. Based on the asymptotic analysis of SR for portfolio losses, several simulation experiments are conducted. This project provides an ideal framework for addressing both extreme risks and dependence.
This is a cutting-edge research project in the field of quantitative risk management and EVT. Systemic risk and catastrophe risk management are hot topics among financial institutions, insurance, and reinsurance companies and the literature is growing fast. As a lesson from the financial crisis of 2007 -2009, modeling Systemic risk must carefully address extreme risks, which result from the marginal tails of and the tail dependence between extreme losses. However, due to the sparsity of data in the tail, the traditional statistic method is no longer as effective, which lends us insights in modeling and simulation via ETV approaches. The proposed research would provide such guidance. It is generally novel because the area of modelling systemic risk under EVT has seen relatively little activity, and in particular nothing that attempts to explore under the extreme risks. There is also methodological novelty since we propose to use a latent variable model to quantify the systemic risks, which equates both endogenous risk and exogenous risk.
