One of the advantages of conduct parameter games is that they enable estimation of market power without total cost data. In line with this, we develop a conduct parameter based model to estimate the firm specific “marginal cost efficiency” and conduct without using total cost data. The marginal cost efficiency is an alternative measure of efficiency that is based on deadweight loss. We illustrate our methodology by estimating firm-route-quarter specific conducts and marginal cost efficiencies of U.S. airlines for Chicago based routes without using route-level total cost data.

The spatial autoregressive stochastic frontier model of Glass et al.(2016) is based on distributional assumptions on two-sided and one-sided error terms. After estimating the model parameters, the efficiency estimates need to be corrected due to the presence of spatial autoregressive term in their model. Glass et al.(2016) estimate the corrected efficiencies by employing ideas from a distribution-free method on the efficiency estimation, which may be sensitive to outliers. We propose an alternative way to correct efficiency estimates that is in line with the distribution-based methods.
