In this book, economist and philosopher Erik Angner provides nine actionable, real-world solutions for fixing the biggest problems that affect our neighbourhoods, politics, businesses and private lives. As he shows, economics is one of the most powerful tools we have at our disposal - it's far too important to be left to economists alone. Economics can help us solve problems such as: how do you build happy communities? How can I get my new-born baby to sleep? How can I become humbler? What is the secret to solving climate change? This revelatory new book is hopeful about the potential for human progress and instructive on how we can all get there together. More than a healthy dose of optimism. How Economics Can Save the World is packed with economic thought, methods and practical tools to help us all use economics as a powerful force for good. In a book filled with wit and lively anecdotes, Angner demonstrates how to see the world differently, and why our biggest problems might not be quite as big as we think.
