----------------- HES POSTING ----------------- Following up on Tony Brewer's comment, two of the best places to start are J.S. Mill's Principles of Political Economy and Henry Sidgwick's Principles of Political Economy. There is a nice line of thought regarding the recognition of the potential extent of market failure that can be traced from Mill, through Sidgwick, to Pigou and his Economics of Welfare. There are certainly other relevant primary sources for this period, but I would suggest that these two are perhaps the most important in terms of marking a turn of view from Smithian natural liberty to a more wider recognition of market failure.
