The dependent structure is modeled by copulas. The risk measures, VaR and ES of such sums, are calculated. We present the lower and upper border of VaR. The examples when the marginals have exponential and Pareto distribution are investigated. The influence of the degree of dependence on the value of VaR of the sum of dependent random variables is analysed.}, title={Aggregate dependent risks - risk measure calculation}, type={artykuł}, keywords={Value at Risk, dependent random variables, copula, Frechet bounds, expected shortfall}, }
