衍生品中有这两句话（见基础版PPT的92页，杨骁慧版）求解释，谢谢！ 1.American options on futures are more valuable than comparable European options. 2.American options on forwards have the same value of comparable European options.

第一句话：因为美式option可在到期之前任意时间执行，而欧式option只能到期执行，所有在其他条件一样的情况下，美式的价格更高

第二句话：如果美式option不提前执行，直到到期日才执行，则美式退化成欧式，两者此时等价

The most important distinction here is the difference between futures contract and forward contract. Futures contracts are standardized and can not be early exercised, whereas forward contracts are OTC and can be early exercised. I guess you know the difference between American and European options.
