Fundamental Theory & Concepts

Core Theory Posts

What Is Opportunity Cost? - IB Economics Foundation Understanding the value of the next best alternative forgone when making choices and why every economic decision involves trade-offs.

Opportunity cost definition | Next best alternative | Economic choice | Trade-offs | Scarcity | Resource allocation | Decision-making | Cost-benefit analysis
