We discuss a simple, exactly solvable model of stochastic stock dynamics that incorporates regime switching between healthy and distressed regimes. Using this model, which is analytically tractable, we discuss a way of extracting expected returns for stocks from realized CDS spreads,...

This thesis lies at the intersection of mathematics, finance and numerical methods. The financial question of how to model credit risk, specifically corporate bond defaults, and how to model correlations between defaults, motivates our study of the mathematics behind a specific kind of credit...

In this paper, we compare different methods for computing default probabilities using a sample of banks that experienced financial distress during the 2007–2009 global financial crisis. The traditional KMV-Merton model for firm valuation, credit ratings by rating agencies and a recently...

In the past thirty years, defaults on corporate bonds have been substantially higher than the historical average. We show that this increase in credit risk can be largely attributed to an increase in the rate at which new and fast-growing firms displace incumbents (a phenomenon sometimes...

This study measures the effects of specific credit risk factors of companies that defaulted during the Asian currency and global credit crises. Using Taiwanese listed companies' data, the predictability of specific credit risk factors were discrepancies during these 2 crises. First, I captured...

Bank credit constraints can reduce firms' ability to borrow to fund hedging and counterparties' capacity to provide hedging services, thus affecting post-hedging outcomes. We find that a one-standard-deviation tighter credit standards increases (post-hedging) exchange rate exposure by 10%. This...

By decoupling economic growth from the exploitation of virgin raw materials and environmental degradation, as well as by developing practices more resilient to the economic cycle, Circular Economy (CE) offers effective hedging of linear risks and shields from that of stranded values. We tested...

Using loan-level data covering two-thirds of all corporate loans from U.S. banks, we document that SMEs (i) obtain much shorter maturity credit lines than large firms; (ii) have less active maturity management and therefore frequently have expiring credit; (iii) post more collateral on both...

The finance literature on carbon risk focuses mostly on the extent to which this risk is currently priced in financial markets. This paper sheds light on a complementary question, i.e. what could be the level of potential carbon risk implied by different future climate policy scenarios. To this...
