Correlation Myths in Financial Risk Management

Giovanni Puccetti's pedagogical article examines common misconceptions about correlation in financial risk modeling. The work uses simplified examples and reproducible R code to demonstrate how misjudging statistical dependence can amplify systemic vulnerabilities, as seen in the misuse of the Gaussian copula during the subprime crisis. It aims to foster critical awareness of quantitative tools among risk managers, regulators, and students.

Use Cases

• [Teaching statistical misconceptions] based on simplified examples and pedagogical discussion
• [Demonstrating risk aggregation errors] based on the treatment of correlation between different risks
• [Reproducing model analysis] based on the included R code
• [Critiquing historical model misuse] based on the reference to the Gaussian copula in the subprime crisis
