包含预期损失检验的预测

Forecast Encompassing Tests for the Expected Shortfall

Timo Dimitriadis, Julie Schnaitmann

摘要:

我们引入新的预测,包括测试的风险措施预期损失(ES)。目前,由于《巴塞尔协议III》规定将ES作为国际银行监管的一级市场风险度量标准,ES受到了广泛关注。我们利用联合损失函数对ES和风险价值建立三个ES包含测试变量。该测试是建立在误设定鲁棒渐近理论,我们调查的有限样本性质的测试在一个广泛的模拟研究。我们使用包含测试来说明不同金融资产的预测组合方法的潜力。

英文摘要:

We introduce new forecast encompassing tests for the risk measure Expected Shortfall (ES). The ES currently receives much attention through its introduction into the Basel III Accords, which stipulate its use as the primary market risk measure for the international banking regulation. We utilize joint loss functions for the pair ES and Value at Risk to set up three ES encompassing test variants. The tests are built on misspecification robust asymptotic theory and we investigate the finite sample properties of the tests in an extensive simulation study. We use the encompassing tests to illustrate the potential of forecast combination methods for different financial assets.
