| Tiivistelmä: | Transport network expansions have usually been analysed calculating returns to scale (RTS) with variable network size, which has been shown to suffer from a number of shortcomings because, in the end, it attempts to capture as a scale property something that in fact is related to scope, namely the addition of new products when a transport network expands. In this article the authors develop a method to calculate economies of spatial scope from transport cost functions with aggregate output, which is then illustrated using the results of a published study on airlines. |
