Professor Petro is one of the giants of the Austrian tradition, and he applied his talents to a particular area of specialization: labor policy. This 1957 book covers three main areas: US labor law and experience, the Austrian theory of labor/capital relations, and the true principle of free association at the heart of the free society. So as Petro sees it, labor economics isn't so much a unique branch of economics but rather the application of the general principles of economics to a specific area. This book then emerged as the definitive Austrian treatment of the topic, and remains so today. It is back in print after being unavailable for many decades. Published as part of the Mises Institute Student Series.
