问题如下:
Which of the following statements regarding externalities is most accurate?
选项:
A.Externalities occur due to environmental or social factors.
When externalities are positive, private costs are lower than societal costs.
Internalization of externalities improves companies’ financial performance.
解释:
A is correct. Externalities can occur due to environmental factors, such as pollution, or social factors—for example, when companies fail to pay a minimum wage. When externalities are positive, private costs are higher than societal costs. When externalities are negative, private costs are lower than societal costs. Internalization of these externalities could significantly impact the costs and profits of companies’ products and services, affecting their bottom line.
C选项中,内部化是指什么?通常情况下没有negative前缀的外部性应该就默认是正外部性,那内部化减小外部性的幅度不就是减少private cost增加social cost吗?所以社会承担变多、公司自身承担变少,performance应该是上升的呀。
