This book demonstrates how economics can improve, make people happy, and make the world a safer place. Our planet is in disarray. Our way of life appears to be in more danger and society is more divided than ever due to issues like climate change, inequality, poverty, and a global pandemic, but economics can help! Economics gives us the skills we need to address today's largest problems, from parenting to organ donation, housing to antisocial behaviour. Economics is a lens through which we can better understand how things operate, design innovative solutions, and establish the conditions in which we can all thrive. It is far from being a tool to forecast the stock market, enrich the few, or follow money throughout the world. With a healthy dose of optimism, and packed with stories of economics in everyday situations, Erik Angner demonstrates the methods he and his fellow economists use to help improve our lives and the society in which we live. He shows us that economics can be a powerful force for good, awakening the possibility of a happier, more just and more sustainable world.
