William Blake (31 January 1774 – 1852) was an English classical economist who contributed to the early theory of purchasing power parity.
[18] Fossati has argued that the debates on money and bank credit for British parliamentary reports of 1804 and 1810 clarified the theory, at the hands of Wheatley and others, including in particular Blake and John Leslie Foster (with Walter Boyd, Lord King, and Henry Thornton).
[19] Joseph Lowe, who wrote many reviews of the pamphlet literature of the bullion debate, approved of Blake's content but complained he was verbose.
Matters of definition still plagued discussion: Ricardo's idea of depreciation clouded, in Blake's view, the issues.
[28] Mill defended Say's law, while Blake was more in sympathy with the views of Robert Malthus on the economic depression of the early 1820s (though he added a disclaimer on not arguing in terms of public policy).
[29][30] Mill in defending Ricardo interpreted the orthodox doctrine on the export of gold in a way that conceded its part in bilateral trade.
[33] Blake married Mary Nash 25 July 1797 (bringing an end to his fellowship) and the estates of John Darker were settled on the couple.
