Table 1 Examples ESTAT-GTAP sector correspondence

One-to-one: one single ESTAT sector corresponds to one single GTAP sectorGTAP IO values fully match those of ESTAT

E.g. insurance (isr), water transport (wtp), air transport (atp), among others

Many-to-one: many ESTAT sectors correspond to one single GTAP sector. The conversion is a simple aggregation

E.g. trade (trd), which gathers “wholesale and retail trade; repair of motor vehicles and motorcycles” (G45, G46, G47), “accommodation” (I55) and “repair of computers and personal and household goods” (S95)

One-to-many: one single ESTAT sector corresponds to many GTAP sectors. Different allocation shares have been used to make the splits

E.g. “electricity, gas, steam and air conditioning supply” (D35), which has to be split up into “electricity” (ely) and “gas manufacture distribution” (gdt); and the “crop and animal production, hunting and related service activities” (A01), which has to be broken down into twelve different GTAP sectors

Many-to-many: many ESTAT sectors correspond to many GTAP sectors. Different allocation shares have been used to make the splits

E.g. “motion picture, video and television programme production, sound recording and music publishing activities” (J59), of which “sound recording and music publishing activities” (J59.2) must be allocated to the GTAP sector “paper products and publishing” (ppp) and “motion picture, video and television programme activities” (J59.1) that has to be allocated to “recreational and other services” (ros). Besides, the GTAP sector “ppp” is also made up of contributions from ESTAT sectors such as “paper and paper products” (C17), “printing and recording services” (C18) and “publishing activities” (J58); and the GTAP sector “ros” is made up of contributions from “creative, arts and entertainment services; library, archive, museum and other cultural services; gambling and betting services” (R90 to R92), “sporting services and amusement and recreation services” (R93), “other personal services” (S96) and “services of households as employers” (T97)
