Marginal Revolution

Marginal Revolution is the blog of Tyler Cowen and Alex Tabarrok, both of whom teach at George Mason University. MR began in August of 2003 and there have been new posts daily since that time. In numerous reviews and ratings over the years Marginal Revolution has consistently been ranked as the best or one of the best economic blogs on the web, but it is more (and less) than that, also representing the quirks of its authors.

  • Some more slow take-off, driven by start-ups
    by Tyler Cowen
    So far, however, the predictions that the mass automation of coding will leave outsourcing firms obsolete seem overblown. Their clients often hope AI will create huge productivity gains by, for example, using the technology to quickly and cheaply build a new internal HR tool. But such improvements in productivity are only possible in “greenfield” environments […]

    by Tyler Cowen
    In 18 parts, Lang explores some of Smith’s central themes, including one of the book’s most famous passages, where Smith uses a wool coat worn by a very poor Scottish worker as a way to examine trade. “He asks, ‘Did you ever think of how many people need to be employed in order to make […]

  • A Danish Fix for U.S. Mortgage Lock-in
    by Alex Tabarrok
    In the Danish mortgage market every mortgage is backed by a corresponding bond. Thus, if a home buyer takes out a 500k mortgage at 3% interest, a bond is issued that pays the lender 3% interest on 500k. I’ve written about this system several times before. It has two distinct advantages. The correspondence principle means […]

  • Consumers vs. mates as a source of selection pressure
    by Tyler Cowen
    Evolutionary biology is one attempt to explain the nature of living beings. In that framework there is a difference between individuals and genes.  If a practice increases the chance that genes will be passed along, it may evolve and be passed along, whether or not it serves either individual or collective self-interest. To give a […]
  • Is AI currently helping economic research?
    by Tyler Cowen
    The third possibility, that AI helps to weed out mistakes, is trickier for the discipline. This stage could become even more important if journals do start to be hit by a wave of AI-generated slop — or, perhaps more likely, good papers with so many appendices and robustness checks that even the most dedicated referee […]
