Hi,

I am working on a model following the approach used by Benlemlih and Bitar (2018), where they have used industry fixed effects and also stated to use OLS with robust standard errors clustered at firm level. Whilst I was trying to apply the approach, I am not sure as how both of these will be incorporated into one model. I am thinking on using the following model, but not sure if its sufficient.

xtreg DV IV controlvar i.year i.SIC fe cluster(SIC)

Does this model suffice all of above mentioned methods (ndustry fixed effects and also stated to use OLS with robust standard errors clustered at firm level) or do i need to use any other additional model?
