This paper investigates the counterparty credit risk of interest rate swaps positions using the credit valuation adjustment (CVA) measure, and examines the potential dependency relationships between the probability of default (PD) and exposure at default (EAD). We empirically tested, using...

Technical inefficiency of production reflects a shortfall of output from the potential permitted by inputs. Allocative inefficiency reflects deviations from the optimal ratio of inputs. It is the absolute value of allocative inefficiency that is economically important. Adding allocative...

We present a general methodology based on skew t copulas and Bayesian inference for modelling extreme multivariate dependent losses and the regulatory capital for operational risk. Current approaches fail to model both asymmetric dependence and accurate extreme upper tail dependence (e.g. 99.9%...

The choice of a copula model from limited data is a hard but important task. Motivated by the visual patterns that different copula models produce in smoothed density heatmaps, we consider copula model selection as an image recognition problem. We extract image features from heatmaps using the...

CEO effort is a vital determinant of a company’s profitability and for shareholder wealth. While effort is not an observable construct, its effects and results are palpable and it is defined as the final point to which the management directs its work. For an agent to perform at optimal levels,...

While environmental, social, and governance (ESG) trading activity has been a distinctive feature of financial markets, the debate if ESG scores can also convey information regarding a company's riskiness remains open. Regulatory authorities, such as the European Banking Authority (EBA), have...

This paper investigates whether multivariate crash risk (MCRASH), defined as exposure to extreme realizations of multiple systematic factors, is priced in the cross-section of expected stock returns. We derive an extended linear model with a positive premium for MCRASH and we empirically confirm...

Food safety is a major risk for agribusiness firms. According to the Centers for Disease Control and Prevention (CDC), approximately 5000 people die annually, and 36,000 people are hospitalized as a result of foodborne outbreaks in the United States. Globally, the death estimate is about 42,000...

Purpose - To discuss subcopula estimation for discrete models. Design/methodology/approach - The convergence of estimators is considered under the weak convergence of distribution functions and its equivalent properties known in prior works. Findings - The domain of the true subcopula associated...
