Human Action, a treatise on economics, perhaps the most important work from Ludwig von Mises. Through careful and rational human decision-making process analysis, Mises gives us strong and compelling arguments for free market capitalism. Ludwig von Mises Institute in Latvia has ordered a translation of this work in the latvian language. And it can be found on this webpage.
