It emphasizes the fundamental economic concepts of scarcity and opportunity cost, illustrating how individuals and societies must weigh benefits and costs in decision-making.

The chapter discusses the importance of designing effective incentives, using examples from public colleges and healthcare. It highlights how poorly designed incentives can lead to unintended consequences, such as universities focusing on enrollment over education quality and the historical example of rat bounties in colonial Vietnam.
