(Nor am I worried about how faithful a model is to Marx's conceptions). The predictions of a model almost always follow from the specifications of the model. What would be valuable, imo, is to develop a reasonably realistic model of a capitalist economy and then to see what outcomes there would be in _alternative_ scenarios. This has long been done in economic forecasting, but not as frequently with truly dynamic models. Of course there are other issues (methodological, ontological, choice of dynamic model, etc.). In solidarity, Jerry
