In this dissertation, we present a compilation of three articles discussing model risk for risk measures. In the first one, using Monte Carlo simulation, we analyze the performance of multivariate models in forecasting Value at Risk (VaR), Expected Shortfall (ES), and Expectile Value at Risk (EVaR). In our numerical evaluation, we consider different scenarios, regarding the marginal distributions, correlation and number the assets of the portfolio, and the following models: Historical Simulation (HS), Dynamic Conditional Correlation - Generalized Autoregressive Conditional Heteroskedastic (DCC - GARCH), Regular copulas, Vine copulas, and Nested Archimedean copulas (NAC). Our results indicate that when the marginal distribution is Gaussian, ...
