Final answer:
The TVaR₀.₉₀ can be calculated using the formula (VaR₀.₉₀ + (VaR₀.₉₉ - VaR₀.₉₀) / (0.09)) / (1 - 0.9). Plugging in the given values, the TVaR₀.₉₀ is 479.60.
Step-by-step explanation:
To calculate the TVaR₀.₉₀, we need to find the average of all values greater than the VaR₀.₉₀. From the given information, the VaR₀.₉₀ is 230.887. We can assume that the Pareto distribution is continuous and monotonically decreasing. Therefore, the TVaR₀.₉₀ can be calculated using the formula:
TVaR₀.₉₀ = (VaR₀.₉₀ + (VaR₀.₉₉ - VaR₀.₉₀) / (0.09)) / (1 - 0.9)
Plugging in the values, we get:
TVaR₀.₉₀ = (230.887 + (728.318 - 230.887) / (0.09)) / (1 - 0.9) = 479.60
