Impact Of Airplane Crashes On Firm's Credit Risk Under The Creditgrades Model, Alexandros Bougias

Undergraduate Economic Review

The paper examines the impact of airplane accidents with 40 or more fatalities, on airline's firm credit risk. The sample contains 20 airplane crashes for the period 2000-2017. The analysis proposes the CreditGrades model introduced by Finger et al. (2002) , which is an extension of the first passage time model of Black and Cox (1976). The study concludes that airplane accidents lead to a statistically significant increase in airline's Probability of Default. The results are both significant and robust under the t-Test and the non-parametric Wilcoxon Signed-rank test.
