What is establishment-level data National level or aggregate level data and firm-level data are self explanatory. I have seen certain papers on productivity analysis as well as other topics which refer to "establishment-level" data. Can someone please explain what is meant by this term?
Establishments are firms at the facility level. Think about it like branches: If a firm has three different branches, each of these branches counts as an establishment. If a firm has no branches, the firm itself is the (sole) establishment.
