Keynesianism, monetarism, market self-regulation - we are all familiar with these terms. But is our knowledge of these economic theories sufficient to be able to use them at a dinner party or at the bar? Economy in 30 seconds explains the 50 most important technical terms and theories on two pages each in words and pictures. Economics suddenly becomes as exciting as economics itself. On his way the reader encounters the fathers of modern economics such as Adam Smith, David Ricardo and Alfred Marshall. From Marxism to Mercantilism, this book is the ultimate crash course in economic theory.
