We argue that standard modeling practices often overstate the potency of general-equilibrium (GE) mechanisms. We formalize the notion that GE adjustment is weak, or that it takes time, by modifying an elementary Walrasian economy in two alternative manners. In one, we replace Rational...

We review how realistic frictions in information and/or rationality arrest general equilibrium (GE) feedbacks. In one specification, we maintain rational expectations but remove common knowledge of aggregate shocks. In another, we replace rational expectations with Level-k Thinking or a smooth...
