英文文献：What Do We Know About Agricultural Producers' Behavior Under Price And Yield Instability?
英文文献作者：Hildreth, Clifford
英文文献摘要：
I interpret unstable prices and yields to imply uncertain prices and yields. One could imagine a situation where controlled prices were announced well in advance but fluctuated according to perceived circumstances at the times of the announcements. Some agricultural programs have approximated the latter, but I take it the main interest here is in supply response with price unknown at the time production and tentative marketing decisions are made.
