Systemic Risk In Financial Networks, Peng-Chu Chen
Open Access Dissertations
This thesis extends the literature of systemic risk in financial networks in two directions.
First, we develop a majorization-based tool to compare financial networks in terms of systemic losses with a focus on the implications of liability concentration. Specifically, we quantify liability concentration by applying the majorization order to the liability matrix that captures the interconnectedness of banks in a financial network. We develop notions of balancing and unbalancing networks to bring out the qualitatively different implications of liability concentration on the system's loss profile. An empirical analysis of the network formed by the banking sectors of eight representative European …

Optimal Monitoring And Mitigation Of Systemic Risk In Lending Networks, Zhang Li
Open Access Dissertations
This thesis proposes optimal policies to manage systemic risk in financial networks. Given a one-period borrower-lender network in which all debts are due at the same time and have the same seniority, we address the problem of allocating a fixed amount of cash among the nodes to minimize the weighted sum of unpaid liabilities. Assuming all the loan amounts and cash flows are fixed and that there are no bankruptcy costs, we show that this problem is equivalent to a linear program. We develop a duality-based distributed algorithm to solve it which is useful for applications where it is desirable …
