Externality
Why do some costs not reach our wallets?
Imagine you're at a picnic, and someone nearby is grilling burgers, releasing smoke. You enjoy the delicious smells but don't pay for the smoke.
Externalities like smoke affect others without them paying. This unpriced effect can lead to too much pollution, as people don't consider the full cost of their actions.
Example
The grill smoke (externality) affects 10 people at the picnic, but nobody pays for it. If each person valued the smoke at $1, the total cost is $10, but it's not reflected in the market.
Remember this
Recognizing unpriced costs helps us see why some activities cause more harm than good and why policies like taxes or regulations might be needed.
