eported in the dissertation will in fact be lower if delays occur. .
In like manner cost curves will be higher than those shown above.
Moreover, to the extent that delays are themselves functions of some
of the same variables in the process function, then productivities
and cost curves may assume different forms than those shown in Chap-
ter V. It is difficult to say anything more on a priori grounds
about the effect of delays on the shape of the productivity and cost
curves. It is left to someone else to provide the required delay
analysis for rail.
In conclusion, it might be said that the results of this dis-
sertation should be of interest to two groups of people: to those ,
who are interested in seeing examples of the "engineering approach"
to the development of production functions and to those who are
interested in the costing of rail and water freight transportation.
- It is hoped that the former group will be satisfied. Indeed, it is
further hoped that they will see the possibilities of applying the
method developed here to. other transportation modes as well. Un-
fortunately for the latter group, the last word has by no means
been said. It is hoped, however, that they recognize an approach
to costing that could be fruitful and which is comparable across
modes. .
