Why are property rights important for internalizing externalities?

• A. Property rights are irrelevant to externalities.
• B. Clear property rights enable bargaining and internalize externalities.
• C. Property rights ensure government allocation of resources.
• D. Property rights eliminate all external costs.

Answer: (B)

Clear property rights let people bargain over the use of resources that affect others, which is how externalities can be internalized. When someone’s actions impose costs or benefits on others, defining who owns or controls the relevant resource gives those affected a stake in the outcome and a basis to negotiate a mutually acceptable agreement. If the rights to a resource are well defined, the parties can trade in a way that reflects the external costs or benefits, leading to a more efficient outcome than if no one could bargain. This is the idea behind the Coasean approach: with low transaction costs and clear rights, private bargaining can align private decisions with social costs and benefits. So, the best choice emphasizes that well-defined property rights enable bargaining and help internalize externalities. It’s not that rights are irrelevant, nor that government allocation is automatically produced by rights, and rights don’t magically erase external costs—they merely facilitate bargaining that accounts for those spillovers when possible.
