The true first edition of the Dutch Nobel Prize winning economist Tjalling Koopmans’s doctoral dissertation, preceding the trade edition published later in the same next year. ‘His doctoral dissertation (1937), now a classic, foreshadowed the style of his important later contributions to econometric methods. In it he brought the insight of Frisch and the rigour of R.A. Fisher to linear regression when all variables are subject to errors of measurement’ (New Palgrave).
