Khipha umehluko phakathi kweNzuzo Elahlwayo Ephelele kusuka kuNzuzo Elahlwayo
Context:Uhlu olungezansi lumelela inkomba etholakala kuma-akhawunti kazwelonke yemali engenayo ephelele yasendlini emuntwini (kuhlanganise nokudluliselwa kwezenhlalakahle ngokwemvelo). Ngokwe-OECD, 'imali engenayo esetshenziswayo yasendlini iyimali engenayo esetshenziswayo yasendlini efana namaholo, imali engenayo evela emisebenzini yokuziphilisa kanye namabhizinisi angahlanganisiwe, imali engenayo evela kumaphensheni kanye nezinye izinzuzo zenhlalo, kanye nemali engenayo evela ekutshalweni kwezimali (ngaphandle kwanoma yiziphi izinkokhelo zentela, iminikelo yomshuwalense wezenhlalo kanye nenzalo yezikweletu zezimali). 'I-gross<unk> isho ukuthi izindleko zokunciphisa izindleko azisusiwe.' Lesi sibonakaliso sibuye sicabangele ukuhanjiswa kwezenhlalakahle "njengempilo noma imfundo enikezwa mahhala noma ngamanani ancishisiwe nguhulumeni nezinhlangano ezingenzi nzuzo". Imininingwane engezansi ishicilelwe yi-OECD futhi ivezwe ngokulingana kwamandla okuthenga (PPP) ukuze kulungiswe umehluko wamanani phakathi kwamazwe.
Kunomehluko oyingqayizivele phakathi kweGross Disposable Income kanye ne-Household Disposable Income. Esokuqala ukuthi "ngama-gross" kubonisa inani eliphelele lemali engenayo etholakala kuyo yonke imithombo efana namaholo, izimali, umsebenzi ozimele, izimpesheni kanye nezinzuzo zomphakathi ngaphambi kokukhipha izindleko zokunciphisa. Imali engenayo yasendlini ihlanganisa yonke imithombo engenayo kususwe izinzuzo zenhlalakahle, izintela, umshuwalense, nezibopho ezifana nerenti, ugesi nezinye izibopho zezimali eziqhubekayo. Lokho okusele kuchazwa ngokuthi imali engenayo esetshenziswayo yasendlini okube sekuhlanganiswa nezinkomba zomhlaba wonke kusetshenziswa i-PPP (i-purchasing power parity) ukuze kulungiswe ukwehluka kwamanani emazweni ahlukahlukene.
