In this study we analyze the determinants of airline price dispersion. We particularly concentrate on the conduct and marginal cost efficiency. The effect of conduct on price dispersion seems to depend on the characteristics of the market. For the big city routes, we observe positive effect; and...

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...

We examine the relationship between cost efficiency of US banks and FED activity level. It turns out that FED actions have a positive effect on cost efficiencies of the US banks. In particular, as the number of Fed actions increases, the cost efficiencies of the US banks increases. This...
