In a market economy, each of us needs protection from manipulation and deception. According to the authors, there are so many sucker hunters in the world today and they are so creative in inventing a variety of traps that, according to the theory of probability, each of us will sooner or later get hooked - no matter how prudent we are. There are no exceptions here. The book, based on an analysis of examples from modern economics, explains how to avoid this by increasing the level of knowledge and introducing the right institutions and reforms. This book is for consumers, entrepreneurs, government officials and anyone interested in modern economic thought. Published in Russian for the first time.
