Scientific contributions

Systemic risk modeling

Work by Cont and his collaborators on mathematical modeling of systemic risk and financial stability, in particular on network models of financial contagion and the modeling of indirect contagion via 'fire sales', has influenced academic research and policy in this area.[John Fell, Francesco Mazzaferro, Richard Portes, Eric Schaanning (2020) Fallen angels and indirect contagion: Rationale for and lessons from a system-wide analysis, 11 September 2020 https://voxeu.org/article/fallen-angels-and-indirect-contagion]

Central clearing

Cont's research on central clearing in over-the-counter (OTC) markets has influenced risk management practices of central counterparty clearing, central counterparties and regulatory thinking on central clearing. Cont has argued that central clearing does not eliminate counterparty risk but transforms it into liquidity risk, therefore risk management and stress testing of central counterparties should focus on liquidity risk and liquidity resources, not capital.

Risk measurement and Model risk

Cont introduced a rigorous approach for the assessment of

model risk In finance, model risk is the risk of loss resulting from using insufficiently accurate models to make decisions, originally and frequently in the context of valuing financial securities. However, model risk is more and more prevalent in activitie ...
