Dear All, Please accept my apologies for the previous post. I was attempting to calculate the TFP for a sample of firms for the period 2001 to 2005 using the levpet command, and wanted to know if one can use time dummies in the free variable list ? Please note that levpet is a user written programme available as a stata module by levinsohn and petrin in their co-authored paper in 2003. Stata Journal article of the same can be accessed at http://www.stata-journal.com/sjpdf.html?articlenum=st0060. The same can be downloaded as ssc install levpet Your help will be highly appreciated.
