Where do Competitive Prices Go? The Long Run Behaviour of a Neoclassical Production Economy, and the Classical Prices of Production

We analyse a general, dynamic neoclassical production economy. We show that any sequence of competitive equilibrium prices converges to a vector of production prices. Thus, far from being a special case, classical prices of production are the attractor of neoclassical equilibrium prices. Indeed, and this is a second insight, prices of production turn out to be the (unique) supporting price vector of the turnpike capital accumulation path. Finally, our results have some implications for theories of exploitation and class, and distributive justice more generally
