The Existence of Aggregate Production Functions<553:TEOAPF>2.0.CO;2-X
p. 553-577

Franklin M. Fisher

It is found that this raises problems not only for capital aggregation but also for the existence of labor and output aggregates. Recent work on the question of using aggregate production functions as approximations is also discussed.
