英文摘要:
The regulator is interested in proposing a capital adequacy test by specifying an acceptance set for firms\' capital positions at the end of a given period. This set needs to be surplus-invariant, i.e., not to depend on the surplus of firms\' shareholders, because the test means to protect firms\' liability holders. We prove that any surplus-invariant, law-invariant, and conic acceptance set must be the set of capital positions whose value-at-risk at a given level is less than zero. The result still holds if we replace conicity with numeraire-invariance, a property stipulating that whether a firm passes the test should not depend on the currency used to denominate its assets.

中文摘要:
监管机构有兴趣提出一项资本充足率测试,具体规定公司在给定期限结束时的资本头寸接受集。这个集合需要是盈余不变的,即不依赖于公司股东的盈余,因为测试意味着保护公司的责任持有人。我们证明了任何盈余不变量、定律不变量和二次曲线接受集都必须是在给定水平上风险值小于零的资本头寸集。如果我们用数字不变性代替圆锥度,结果仍然成立。数字不变性规定,企业是否通过测试不应取决于其资产的计价货币。
