Combined COVID 19 MENA Monitor Enterprise Survey, CCMMENT – Wave1_Wave2_Wave3

Cross Sectional Data
========
Files: COVID-19 Monitor All FIRM 2021 rep xs v3.0.dta

NOTE: The cross sectional (one point in time) or repeated cross sectional (multiple points in time) data structure should be used for all point-in time-analyses. The data are structured so that a unique observation is a firm.

Important Variables:
==============
1- firmid: Unique firm identifier - wave specific
2- Ffirmid: Unique firm identifier - when first observed

Panel data
========
Files: COVID-19 Monitor All FIRMS 2020-2021 panel v3.0.dta

NOTE: The panel data are structured so that an observation is a unique firm (wide data), and time-varying variables have a _w# suffix where # denotes the wave. This data structure should be used for any analysis of transitions, whether from February 2020 (#=0) or across specific wave point in times (#), or any combination of these times.

The Panel important variable names [where the first # is the base wave and the second # is the subsequent wave]:
· Firm weight: firm_wt_#
· Firm panel weight: panel_wt_#_#
· Unique Firm identifier: firmid_#
