(1) Scott McDonald noted that the first known application of RAS in economics was reported in: "Stone, R., Bates, J. M. and Bacharach, M. (1963) A Programme for Growth, vol. 3, Input-Output Relationships 1954-1966. London: Chapman and Hall". Theses by Barcharach (Cambridge, 1965) and Omar (Nottingham, 1967) explored the properties.

(2) On page 35 a footnote 2 states: "The abbreviation RAS seems to be introduced by Richard Stone in some notes; presumably the A stands for the Leontief matrix, and R and S for his initials (Lahr and De Mesnard 2004)". Scott, whose PhD was supervised by John Bates at the University of Nottingham, remembers being informed by John Bates that R referred to the row multiplier and that S, for the column vector, was the next letter in the alphabet.

(3) On page 40 it is stated that the Stone-Byron  "..... approach was proposed already by Stone (1976) and further formalized by Byron (1978), the approach is often called the Stone-Byron method." This sentence  should rather read "... approach was proposed already by Stone et al. (1942) and Stone (1977) and further formalized by Byron (1978), the approach is often called the Stone-Byron method."  The references are "Stone, R. 1977. “Foreword.” In: Social Accounting for Development Planning with Special Reference to Sri Lanka (G. Pyatt et al., eds). Cambridge: Cambridge University Press" and "Stone, R., Champernowne, D. G. and Meade, J. E. (1942) The precision of national income estimates. Review of Economic Studies, Vol 9, 111-125".
