Sometimes price swings are just part of supply and demand, and don’t have spill over effects to other parts of the economy.
有时价格波动只是供求关系的一部分，不会对经济的其他部分产生溢出效应。

Spillover effect
（重定向自Spill over effect）
In economics, spillover effects are economic events in one context that occur because of something else in a seemingly unrelated context. For example, externalities of economic activity are non-monetary effects upon non-participants. (Odors from a rendering plant are negative spillover effects upon its neighbors; the beauty of a homeowner's flower garden is a positive spillover effect upon neighbors.)
