1. The ‘direct contribution to the balance of payments' of Dutch gas exploitation refers to the sum of both export value and the value of import substitution.
2. The influence of natural gas on the balance of current account, as incorporated in the calculations underlying figure 1, is equal to 2/3 the size of the direct effect. For a comment on this, see for example: J. Weitenberg,De betekenis van het aardgas voor onze economie (The Importance of Natural Gas for Our Economy), C.P.B. reprint, No. 151, The Hague, 1975; and: C.J. Jepma, ‘Is de Nederlandse ziekte chronisch?’ (Is the ‘Dutch Disease’ Chronic?) in: S.K. Kuipers (ed.),Vooruitzichten voor de Nederlandse economie (Prospects for the Netherlands' Economy), Leiden, 1980, pp. 41–63.

5. The fact that CMS analysis is employed in the OECD studies is apparent in, for example, a remark in footnote 18 ofEconomic Surveys: The Netherlands, Paris, 1976, p. 24.
