From Economies of Density and Network Scale to Multioutput Economies of Scale and Scope: a Synthesis

For more than twenty years, the cost structure of transport industries in general, and the airline industry in particular, has been analyzed through the calculation of two indices: returns to density (RTD) and returns to scale (RTS), which were originally proposed by Caves et al.

The paper also eval...
