Founded in 2012 by George Mason University economics professors Tyler Cowen and Alex Tabarrok, Marginal Revolution University is building the world's largest online library of free economics educational resources -- currently weighing in at more than 900 videos plus hundreds of classroom resources.Since 2003, Tyler and Alex have co-authored a popular economics blog called Marginal Revolution -- hence the name of this educational platform. What is the "marginal revolution" exactly? The term refers to an exciting time in the history of economics when several leading nineteenth century thinkers (Walrus, Menger, and Jevons) formalized what is now known as marginalism theory. In other words, thinking on the margin, which is something you too will master as you dive into MRU videos. We also like the idea that revolutions are made one idea and one person at a time.Our small, distributed team operates out of Arlington, VA and around the the globe to create Marginal Revolution University content that's used worldwide (interested in joining us?). Whether it's an overview of micro and macro principles, a "duel" between leading thinkers, or a primer on the rise and fall of China's economy, MRU's videos bring viewers up to speed on what they need to know about economics.And yes, as part of a non-profit, our resources are free(!) and easily accessible on both our website and YouTube.
