Editing Economies of scale (section)

===Economies of scale in Marshall===
[[Alfred Marshall]] notes that [[Antoine Augustin Cournot]] and others have considered "the internal economies [...] apparently without noticing that their premises lead inevitably to the conclusion that, whatever firm first gets a good start will obtain  a  monopoly of the whole business of its trade … ".<ref>{{harvp|Marshall|1890|loc=380, note 1}}; cf. {{harvp|Cournot|1838|pp=96 ff.}}</ref>  Marshall believes that there are factors that limit this trend toward monopoly, and in particular:
* the death of the founder of the firm and the difficulty that the successors may have inherited his/her entrepreneurial skills;
* the difficulty of reaching new markets for one's goods;
* the growing difficulty of being able to adapt to changes in demand and to new techniques of production;
* The effects of external economies, that is the particular type of economies of scale connected not to the production scale of an individual production unit, but to that of an entire sector.{{sfnp|Marshall|1890|pp=232–238, 378–380}}
