The Chicago Price Theory initiative has a Master Class and it is highly recommended. But I would like to have a discussion with my good friends @BryanPCutsinger @BrianCAlbrecht etc. about a carefully listening to Kevin Murphy's wonder introduction. See min 1:45-2:15, where he discusses the problem of cutting the story too short. This of course was a point McCloskey hammered home in her Applied Theory of Price and elsewhere -- DO NOT CUT THE STORY SHORT -- keep pressing the logic of the economics forces _at work_. But then also listen carefully to the discussion shortly after on the importance of competition. As Murphy puts it, competition ensures that if there are gains from trade to be had people will, as he puts it, "try to get them." In both instances, the power of price theory is in guiding exchange and production behavior to pursue productive specialization and realize the gains from peaceful social cooperation. Optimality conditions are by-products of a process of adaptation and adjustment, not assumptions. We are constantly groping toward equilibrium, not trapped in it at each instant in time. Our models, as such, may imperfectly capture what it is that we want to explain -- exchange and the institutions within which those exchanges take place. As a result we can either question the model, or ignore the process. But if we ignore the process we lose the power of price theory in our depiction. As both Alchian and Buchanan stressed the market is best understood and in a constant state of becoming and exhibiting the pattern of an evolution toward a solution. And not just characterized by the solution concept itself.
