摘要

The paper uses GARCH models to measure the volatility of EUA spot price and futures price, calculates the value of CVaR under the normal distribution, t-distribution, and generalized error distribution (GED) based on GARCH models, and compares the precision of one-day values of CVaR for different models by using DLC statistics. The result shows the EGARCH model can be regarded as the best models for calculating the CVaR for time-varying market risks. In addition to that, according to the models of GARCH group, the asymmetry between spot market and futures market of EU ETS also can be found, with leverage effect, and favorable news can bring much bigger impacts to carbon market in comparison with bad news.
