WebEstimating demand elasticity econometrically. When specifying a production function for regression, it is well known that one of the features of using a log-log model is that the estimated coefficients are the output elasticities w.r.t. their respective independent variables. My question is does it then follow that if one regresses log ...

The models use different ways to get the fixed-effect coefficient estimates, and it might help to think a bit differently about the interpretations of the coefficients in the two models. In general the estimates of fixed-effect coefficients won't agree in the two types of models. The simple linear regression model ignores all of the ...
