Mises Claims That All Nonmonetary Explanations of the Business Cycle Are Invalid

I show that RBC [Real Business Cycle] theory, in all of its variations, is not a valid theory of the business cycle. Hence, it does not provide a valid explanation of recessions and depressions. This is the case primarily because it does not explain the type of economy-wide fluctuations we see and the events that occur on the side of money during the business cycle. These observations, in essence, were made long ago by the great Austrian economist Ludwig von Mises in his comments on nonmonetary explanations of the business cycle. He showed that they are all invalid. My analysis goes much farther than Mises’s analysis because I go into much more detail to show why RBC theory is invalid. I also cover a far broader range of topics than Mises. However, his analysis does serve as a guide for my analysis.
