If, on the other hand, the public is basically right about heightened disaster risks, the policy issues become much more complex. The problem is that the government likely faces high costs if a disaster strikes, which implies a high option value to preserving fiscal space for when it is most needed.
但如果公众对灾难风险上升的认知基本正确，那么政策问题就远没有如此简单。问题在于一旦灾难来袭政府很可能面对高额成本，也就是说政府要在最必要的时刻为保持财政地位付出更高的期权价值。
