(4 Points) The following model is used to explain pricing by the airline with the largest market share by US airport. MODEL: PDOM = 0 + $1*MSLGE + $2*MSSMALL + 83*SMFARE + 34*MILES. Where PDOM = average fare of largest (in terms of market share) carrier. MSLGE = market share of the largest airline or dominant carrier. MSSMALL = market share of the low fare carrier. SMFARE = average fare of the low fare carrier. MILES = Distance of the route (proxy for cost factors). I downloaded 5,569 observations by airport and estimated the above model. The Excel output is shown below.
