A sudden supply shock in the global market for a critical rare-earth metal causes its market price to rise sharply. In a market economy, how does the price mechanism function to reallocate scarce resources in response to this event?
Scarce supplies of the metal are rationed to buyers with the highest willingness and ability to pay, while the higher price incentives producers to allocate more resources to extraction and substitute technologies.
The price mechanism automatically triggers government-legislated quotas to ensure that key strategic industries are allocated a guaranteed minimum share of the metal.
The higher price signals to consumers that the social marginal cost of extraction has fallen, incentivizing them to expand their consumption of the resource.
Resources are redistributed equally among all domestic manufacturers to prevent monopolistic exploitation and ensure allocative efficiency.
