This study examines the effects of allocative distortions on returns to density and input demand in domestic airlines during 1989-1997 by using a non-minimum cost function from the cost efficiency point of view. We generalize a globally concave and flexible cost function by using the symmetric generalized McFadden cost function to accommodate allocative distortions for domestic airlines, and estimating the density economies with and without allocative distortions as well as its effect on cost efficiency.
