Money implies the state and taxation, and a mechanism by which the value of money is fixed. Sraffa and Marx attempt to get round this by assuming that money is a commodity - do you assume this? > Ex-post value accounting allows unit values of inputs and outputs > to be different and allows the value of money to change.
