I'm using "reg3" command to estimate a simultaneous system of demand and supply. I've a world demand equation and 2 supply equations. For this I need to calculate elasticities for all the years so that I can comment on change in market power (a function of elasticities) over the years.
My dataset is from CEPII (bilateral trade flows), there already has been some discussion on dataset from CEPII on how to declare it as a panel dataset.
The "reg3" command does not runs with the panel setting, does anyone knows how to run the simultaneous system in panel setting?
Thanks.
