Meek, Dickinson and Marx's Falling Rate of Profit

In the 1950s and 60s Meek and Dickinson argued that, in a Marxian model, the rate of profit would first rise and then fall as capital accumulated. In their recent A History of Marxian Economics, Howard and King accord this argument the same status as the Okishio theorem. This paper reassesses the argument. It shows that Dickinson's argument violates a basic tenet of the neo-marxian model but that Meek's example may be consistent with an extended version of the same model.
