Macleod was a director of the Royal British Bank, after the failure of which he was one of those convicted of conspiracy to misrepresent the bank's financial position,[4] and was sentenced to 3 months imprisonment.[5]
He was employed in Scotland on the work of poor-law reform, and devoted himself to the study of economics. In 1856 he published his Theory and Practice of Banking,[6][7] in 1858 Elements of Political Economy,[8] and in 1859 A Dictionary of Political Economy.[9] In 1873 his Principles of Economical Philosophy[10][11] appeared, and in 1889 his The Theory of Credit.[12][13][14] Between 1868 and 1870 he was employed by the government in digesting and codifying the law of bills of exchange.[3] In 1896, he published The History of Economics.[15]
Macleod's principal contribution to the study of economics consists in his work on the theory of credit, to which he was the first to give due prominence.[3] A major feature of his work was to create a theory of money starting from a theory of credit instead of the usual reverse path. In The Theory of Credit he says:[16]
Money and Credit are essentially of the same nature:
Money being only the highest and most general form of Credit
The English leaders from Thornton to Mill did explore the credit structure, and in doing so made discoveries that constitute their chief contributions to monetary analysis but could not be adequately stated in terms of the monetary theory of credit. But they failed to go through with the theoretical implications of these discoveries, that is, to build up a systematic credit theory of money...
Then, he adds a footnote:
We might see the outlines of such a theory in the works of Macleod. But they remained so completely outside of the pale of recognized economics...
Henry Dunning Macleod [...] was an economist of many merits who somehow failed to achieve recognition, or even to be taken quite seriously, owing to his inability to put his many good ideas in a professionally acceptable form.
