Harvey, David. Marx’s Refusal of the Labour Theory of Value, March 1, 2018
Claim: "Marx’s value form is not a still and stable fulcrum in capital’s churning world but a constantly changing and unstable metric", influenced by markets, changes in technology, social reproduction and other factors.
Marx never aligned with labour theory of value and instead proposed his own "value theory".
Who deals with: Ricardo, labour theory of value.
Method: Picks up the main points of labour theory of value that add little to Ricardo's theory, but then claims that few Marxists notice that Marx went further, and shows where.
Notes:
Marx's theory of value is, in contrast to Ricardo's, who is looking only at production and circulation, argues that value is rather an outcome of negotiaton between competitive market processes, surplus value production and social reproduction. The latter is something that Marx devises after his comparative studies of living conditions and rationing among workers and prisoners.
