1. Final dataset: FDI in 3 dimensions (i, r, s)
Constraint 1: Maximum value for all FDI for a country r, associated with its discret support and prior
IMF (BOP) (r)
Or UNCTAD (r)
Scaling in and out FDI
WiiW, China
(i,s) or (r,s)
Eurostat (i,r,s)
Constraint 2: Intermediate constraints with 2 dimensions
Gathering all raw data
3 years average to avoid volatility
Negative values are set to zero
OECD
(i,s) or (r,s)
Constraint 3:
Slightly change
Eurostat (i,r,s)
Econometric estimates
(Gravity model – PQML to deal with 0)
Used to estimates missing values in 3 dimensions.
Estimating missing values
Set of « real » values (2 dimensions data can marginaly change during the balancing procedure)
Balancing the database
Harmonization of mirrors flows with a balancing procedure:
Quadratic optimization s.t. constraints 1,2,3
