Ukuze uqhathanise amandla okuthenga ezinhlobo zemali zamazwe ahlukene, indlela yezibalo isetshenziswa okuyiyo ukulingana kwamandla okuthenga. Izinga lokushintshisana kanye nokulingana kwamandla okuthenga akufanele kudidaniswe. Ukuze ugweme lokhu, sizokukhanyisela ngendaba yokuthenga amapheya amandla.
Yini leyo ? Ubani ozisebenzisayo? Ngenzenjani ngempela? Siphendula yonke le mibuzo ngezansi.
Yiziphi izingxenye zamandla okuthenga?
Purchasing power parity (PPP) kukhona amanani okuguqulwa kwemali ezikhombisayo umehluko emazingeni okuphila phakathi kwamazwe ahlukene. Ama-PPP asetshenziselwa ukulinganisa amandla okuthenga ezinhlobo zemali ezihlukahlukene, ngaphandle kokucabangela umehluko wamazinga entengo.
Ngamanye amazwi, amandla okuthenga amapheya ayizilinganiso zentengo yento efanayo noma isevisi ngemali kazwelonke.
Kukhona izinhlobo ezimbili zamapheya amandla okuthenga:
- I-PPP ephelele,
- I-PPP ehlobene.
I-PPP ephelele inqunywa ngo isikhathi esithile, mayelana nobhasikidi ababili abasetshenziswayo emazweni amabili ahlukene. I-PPP ephelele ichazwa ngokuqhathanisa intengo yalawa mabhasikidi amabili afanayo emazweni amabili.
I-PPP ehlobene ichaza uguquko kumapheya amandla okuthenga aphelele ngezikhathi ezimbili ezahlukene.
Ungabala kanjani amandla okuthenga amapheya?
Ukubalwa kwama-party amandla okuthenga kuyenziwa izindlela ezimbili ezahlukene, kuye ngohlobo lokulinganisa kwamandla okuthenga.
I-Absolute PPP Ukubala
Ifomula yokubala ukulingana okuphelele kwamandla okuthenga phakathi kwamazwe amabili ithi: PPPt =Pt/Pt
