Financial networks have shown to be important in understanding systemic events in credit markets. In this paper, we investigate how the structure of those networks can affect the capacity of regulators to assess the level of systemic risk. We introduce a model to compute the individual and...

One of the important limitations of the SRISK measure of systemic risk, proposed by Brownlees and Engle and Acharya, Engle and Richardson, is its reliance on stock market data without much validation against the institutions' fundamentals based on its financial statements. We propose a financial...

We analyze covariance matrix estimation from the perspective of market risk management, where the goal is to obtain accurate estimates of portfolio risk across essentially all portfolios—even those with small standard deviations. We propose a simple but effective visualization tool to assess...

A credit valuation adjustment (CVA) is an adjustment applied to the value of a derivative contract or a portfolio of derivatives to account for counterparty credit risk. Measuring CVA requires combining models of market and credit risk to estimate a counterparty's risk of default together with...

The DuPont decomposition of profitability into profit margin and asset turnover has been applied extensively to forecast future profits. This paper provides a complementary analysis under which the DuPont decomposition also informs about the risk that profits may differ from expectation. In the...

We analyze the optimal allocation of trades to portfolios when the cost associated with an allocation is proportional to each portfolio's risk. Our investigation is motivated by changes in the over-the-counter derivatives markets, under which some contracts may be traded bilaterally or through...
