ABSTRACT
These payments are looked upon as contracts determined at the beginning of the period and running for one period. This applies also to 'normal profits', i.e. the entrepreneurs' income "in their capacity of owners of productive services" (Hammarskj6ld 1933A, p.l3). Thus the changes in the price level for consumer goods and the concomitant windfall profit are the only unanticipated factors for the period. The idea of fixing the payments for productive services for the forthcoming period is later taken up by Lindahl in his "A Note on the Dynamic Pricing Problem" of 1934.
