A stochastic volatility model for the valuation of temperature derivatives

"This model allows to be more conservative regarding extreme events while keeping tractability. We give a method based on Conditional Least Squares to estimate the parameters on daily data and estimate our model on eight major European cities... This new model allows to better assess the risk related to temperature volatility."

Quasi‑convexity in mixtures for generalized rank‑dependent functions

Date : Tags : , , ,
"Quasi-convexity in probabilistic mixtures is a common and useful property in decision analysis. We study a general class of non-monotone mappings, called the generalized rank-dependent functions, which include the preference models of expected utilities, dual utilities, and rank-dependent utilities as special cases, as well as signed Choquet integrals used in risk management."

Loss Aversion Leads to Fatalistic Management of Interdependent Risk

Date : Tags : , , , ,
"The higher the degree of loss aversion, the lower is the likelihood to invest in other risk management activities is when self-protection is implemented. Our results help to explain the lack of demand for catastrophe insurance or cyber risk insurance and have important implications for corporate risk management and public policy."

Should Bank Stress Tests Be Fair?

Date : Tags : , , , , , ,
"We argue that simply pooling data across banks treats banks equally but is subject to two deficiencies: it may distort the impact of legitimate portfolio features, and it is vulnerable to implicit misdirection of legitimate information to infer bank identity. We compare various notions of regression fairness to address these deficiencies, considering both forecast accuracy and equal treatment. In the setting of linear models, we argue for estimating and then discarding centered bank fixed effects as preferable to simply ignoring differences across banks."

What Drives Bank‑Specific Capital Requirements? Evidence from the Ssm

Date : Tags : , , , , , , ,
"Drawing on recently disclosed information on the Pillar 2 capital requirements of banks directly supervised by the ECB, we find that bank-specific capital requirements are mostly driven by business model and profitability, credit risk, and internal governance and risk management issues. Moreover, we propose a novel measure of bank governance quality that teases out the qualitative dimension of the P2R decision."
