Dealing with mirror data • When some data are missing, it can be useful to use partner’s mirror data (exports – imports) to fill gaps. • However, one has to be very careful because: • Of the FOB – CIF issue; • Of the difference in reporting quality when a country deals with imports and exports; • Of the difference in reporting quality from one country to another. • Example: Pakistan (exports)– China (imports) in 2001 236 M US$ 557 M US$
Querying TRAINS • TRAINS – Trade, tariffs, NTBs produces output for the value of imports at the tariff line level (where available) for all partners, for a single product in a single year. • TRAINS – View and export raw data produces output for the value of imports at the tariff line level for all products, for a single year. • TRAINS - User criteria allows for retrieving all import lines above a user specified value.
