(b) Based on these calculations, which industry most closely resembles perfect competition?

[removed]

Transportation.

(c) Which industry most closely resembles monopoly?

Transportation.

Note:TheRothschild index is given by,

R = ET/EF

where ET is the elasticity of demand for the total market and EF is the elasticity of demand for the individual firm’s product.

For perfect competitionRothschild index is 0 and 1 for monopoly so its value lies in between 0 to 1.
