Health economics is often seen as a complicated subject filled with numbers, graphs, and formulas. Yet at its heart, it is about something simple and essential: making the best use of limited resources to improve people’s health. Every health professional whether working in clinics, hospitals, research, or policy, makes decisions that are influenced by economics, even if they don’t always realize it.

This open book, Intro to Health Economics: What Every Health Professional Should Know, was created to make health economics clear, practical, and relevant. Instead of heavy theory, it focuses on real-world applications that health professionals face daily, from deciding which treatments to prioritize, to understanding how governments fund health programs, to exploring why equity matters just as much as efficiency.

Designed with students and practitioners in mind, the chapters include simple explanations, local and global examples, and interactive activities to bring concepts to life. The aim is not to train readers to become economists, but to give them a toolkit: a way of thinking critically about costs, benefits, and choices in healthcare.

Ultimately, health economics is not just about numbers but it is about people. It helps us ask tough questions: How do we provide the best care for the most people? How do we balance fairness with limited budgets? How do we design policies that truly make a difference?

This book invites you to explore those questions. It is written to guide, inspire, and empower you as a future health leader to make decisions that matter especially for patients, communities, and society.
