'''Marginal thinking''' is the economic process of making optimal decisions by comparing the additional (marginal) benefits to the additional (marginal) costs of a specific action, rather than focusing on total costs. It focuses on whether to add "one more unit" — such as one more hour of study or producing one more item—to maximize utility or profit, crucial for rational, incremental decision-making.
== Key Concepts of Marginal Thinking ==
* Marginal Benefit (MB): The extra gain from increasing an activity by one unit.
* Marginal Cost (MC): The extra expense or effort incurred by increasing an activity by one unit.
Decision Rule: If MB > MC, take the action. If MB < MC, do not take the action.
Ignoring sunk costs: Marginal thinking disregards past, unrecoverable costs (time or money already spent) and focuses only on future, incremental costs and benefits.
