> And most importantly, economics assumes that the market is perfect, which it most certainly is not in practice. do physicists assume frictionless surfaces and perfectly elastic collisions? yes when they're explaining the basics of Newton's Laws, but they also develop theories and models for friction, etc. Same with economists, they study economies and do their best to come up with complete models. Are they perfect? no. Do they know more about economies than anybody else? yes.
