Indlela Yokubala Ukuqina: Umhlahlandlela Ophelele
Ukunwebeka kuwumqondo obalulekile kwezomnotho olinganisa ukusabela kwenguquko eyodwa ezinguqukweni kwenye. Leli gama livame ukusetshenziswa ezimweni ezahlukene zomnotho, njengokunwebeka kwesidingo, ukunwebeka kokuhlinzekwa, kanye nokunwebeka kwemali engenayo. Lesi sihloko sizochaza indlela yokubala ukunwebeka kanye nokusetshenziswa kwayo ezimweni ezahlukene zomnotho.
Ukuqonda Ukunwebeka
Ukunwebeka kuyisilinganiso sokuthi i -economic variable ibucayi kangakanani ezinguqukweni kwenye i-variable. Ngokwezibalo, ukunwebeka kuchazwa njengoshintsho lwephesenti ku-variable eyodwa olubangelwa ushintsho lwephesenti kwenye i-variable. Ukunwebeka kungaba kuhle noma kube kubi kuye ngobudlelwano obuphakathi kwalezi zi-variable ezimbili.
Izinhlobo Zokuqina
Kunezinhlobo eziningana zokunwebeka okuvame ukuxoxwa ngazo kwezomnotho :
1. Ukunwebeka Kwesidingo Sentengo (PED) – Kulinganisa ukusabela kwenani lezimpahla ezifunwayo ezinguqukweni zentengo yalezo zimpahla.
2. Ukunwebeka Kwentengo Kokuphakelwa (i-PES) – Kulinganisa ukusabela kwenani lezimpahla ezinikezwayo ezinguqukweni zentengo.
3. Ukunwebeka Kwesidingo Semali Engenayo (YED) – Kulinganisa ukusabela kwesidingo ezinguqukweni zemali engenayo yabathengi.
4. Ukunwebeka Kwesidingo Esihambayo (CED) – Kulinganisa ukusabela kwesidingo sempahla ezinguqukweni zentengo yempahla ethile.
Ifomula Ejwayelekile Yokubala Ukuqina
Kuhlobo ngalunye lokuqina, ifomula ejwayelekile yile:
\[ E = \frac{\%\ \text{Shintsha ngobuningi}}{\%\ \text{Shintsha ngokuguquguquka kwembangela}} \]
Kuphi:
– \( E \) ukuthamba.
– \% Ushintsho ku-Ubuningi ushintsho lwephesenti enanini elifunwayo noma elinikeziwe.
– \% Ushintsho ku-Causal Variable kungaba intengo, imali engenayo, noma intengo yesinye isitolo.
Indlela Yokubala Ukuqina Kwentengo Yesidingo
Ukuqina kwentengo kwesidingo kubalwa kusetshenziswa ifomula:
\[ PED = \left| \frac{\%\ \text{Shintsha ngobuningi} }{ \%\ \text{Shintsha ngobuningi}} \right| \]
Nazi izinyathelo:
1. Bala Ushintsho Lwenani: Susa inani lokuqala enanini elisha, bese uhlukanisa umehluko ngenani lokuqala. Bese, phinda-phinda ngo-100 ukuze uthole iphesenti.
\[ \%\ \text{Ushintsho kuBuningi} = \frac{\text{Ubungani Obusha} – \text{Ubungani Bokuqala}}{\text{Ubungani Bokuqala}} \times 100 \]
2. Bala Ushintsho Lwentengo: Susa intengo yokuqala entengo entsha, uhlukanise umehluko ngentengo yokuqala, bese uphinda-phinda ngo-100.
\[ \%\ \text{Ushintsho Lwentengo} = \frac{\text{Intengo Entsha} – \text{Intengo Yokuqala}}{\text{Intengo Yokuqala}} \times 100 \]
3. Ngena kufomula ye-PED:
\[ PED = \left| \frac{\%\ \text{Shintsha ngobuningi} }{ \%\ \text{Shintsha ngobuningi}} \right| \]
Isibonelo:
Uma intengo yezimpahla ikhuphuka kusukela ku-Rp. 100.000 kuya ku-Rp. 120.000 futhi inani elifunekayo lehla kusukela kumayunithi angu-50 kuya kumayunithi angu-40, khona-ke:
\[ \%\ \text{Ushintsho kuBuningi} = \frac{40 – 50}{50} \izikhathi eziyi-100 = -20\% \]
\[ \%\ \text{Ushintsho Lwentengo} = \frac{120.000 – 100.000}{100.000} \izikhathi eziyi-100 = 20\% \]
\[ I-PED = \kwesobunxele| \frac{-20}{20} \kwesokudla| = 1 \]
Indlela Yokubala Ukuqina Kwentengo Kokunikezwa
Ukuqina kwentengo yokunikezwa kubalwa kusetshenziswa ifomula efana cishe ne-PED:
\[ PES = \left| \frac{\%\ \text{Shintsha Inani Elinikeziwe}}{\%\ \text{Shintsha Intengo}} \right| \]
I-Langkah-langkah:
1. Bala ushintsho lobuningi olunikeziwe njengakuqala.
2. Bala ushintsho lwentengo njengakuqala.
3. Faka kufomula ye-PES.
Indlela Yokubala Ukunwebeka Kwemali Engenayo Yesidingo
Ukuqina kwesidingo semali engenayo kubalwa kusetshenziswa ifomula:
\[ YED = \left| \frac{\%\ \text{Ushintsho Lobuningi Luyadingeka}}{\%\ \text{Ushintsho Lomholo}} \right| \]
Izinyathelo:
1. Bala Ushintsho Lwenani ngokwezinyathelo ku-PED.
2. Bala Ushintsho Emalini Engenayo: Susa imali engenayo yokuqala emalini engenayo entsha, uhlukanise umehluko ngemali engenayo yokuqala, bese uphinda-phinda ngo-100.
\[ \%\ \text{Income Change} = \frac{\text{New Income} – \text{Initial Income}}{\text{Initial Income}} \times 100 \]
3. Ngena kufomula ye-YED:
\[ YED = \left| \frac{\%\ \text{Shintsha ngobuningi} }{ \%\ \text{Shintsha ngomholo}} \right| \]
Isibonelo:
Uma imali engenayo abathengi bakhuphuke kusuka ku-Rp. 10.000.000 kuya ku-Rp. 12.000.000 kanye inani elifunekayo lento liyanda lisuka kumayunithi angu-40 liye kumayunithi angu-50, bese kuba:
\[ \%\ \text{Ushintsho kuBuningi} = \frac{50 – 40}{40} \izikhathi eziyi-100 = 25\% \]
\[ \%\ \text{Income Change} = \frac{12.000.000 – 10.000.000}{10.000.000} \times 100 = 20\% \]
\[ YED = \kwesobunxele| \frac{25}{20} \kwesokudla| = 1,25 \]
Indlela Yokubala Ukuqina Kwesiphambano Sesidingo
Ukuqina kwesidingo kubalwa kusetshenziswa ifomula:
\[ CED = \left| \frac{\%\ \text{Ushintsho Ebuningini Obufunwayo Kokuhle X}}{\%\ \text{Ushintsho Entengo Kokuhle Y}} \right| \]
Izinyathelo:
1. Bala Ushintsho Ebuningini (bento X) ngokwezinyathelo eziku-PED.
2. Bala Ushintsho Lwentengo (izimpahla Y) ngokwezinyathelo eziku-PED.
3. Ngena kufomula ye-CED:
\[ CED = \left| \frac{\%\ \text{Ushintsho eNanini le-X Elihle}}{\%\ \text{Ushintsho eNanini le-Y Elihle}} \right| \]
Isibonelo:
Uma intengo ye-Y enhle ikhuphuka isuka ku-Rp. 50.000 iye ku-Rp. 60.000 kanye nenani elifunekayo lokwenyuka kwe-X enhle lisuka kumayunithi angu-30 liye kumayunithi angu-35, khona-ke:
\[ \%\ \text{Ushintsho kunani lokuhle X} = \frac{35 – 30}{30} \izikhathi eziyi-100 = 16,67\% \]
\[ \%\ \text{Ushintsho lwentengo ka-Y omuhle} = \frac{60.000 – 50.000}{50.000} \izikhathi eziyi-100 = 20\% \]
\[ CED = \kwesobunxele| \frac{16,67}{20} \kwesokudla| = 0,83 \]
Ukuhunyushwa Kokunwebeka
Ukunwebeka kubalwa njengenani eliphelele, kodwa imiphumela ingahunyushwa ngezindlela eziningana:
1. Ukunwebeka (>1): Ushintsho olukhulu lwephesenti ku-variable efunwayo noma enikeziwe ngenxa yoshintsho ku-causal variable. Isibonelo, uma i-PED = 2, ushintsho lwe-10% entengo luzoshintsha inani elifunwayo ngo-20%.
2. I-Inelastic (<1): Ukusabela kuncane kakhulu, okusho ushintsho oluncane lwephesenti ku-variable efunwayo noma enikeziwe naphezu koshintsho olukhulu ku-causal variable. Isibonelo, uma i-PED = 0,5, ushintsho lwe-10% entengo luzoshintsha kuphela inani elifunwayo ngo-5%.
3. Iyunithi yokunwebeka (1): Izinguquko entengo zithinta inani elifunwayo noma elinikezwayo ngesilinganiso esifanayo. Isibonelo, i-PED = 1 isho ukuthi ushintsho lwe-10% entengoni lubangela ushintsho lwe-10% enanini elifunwayo.
Isiphetho
Ukunwebeka kuyithuluzi elibalulekile lokuhlaziya izindlela ezahlukene zomnotho . Ngokuqonda ukuthi singabala kanjani izinhlobo ezahlukene zokunwebeka, okuhlanganisa ukunwebeka kwentengo yesidingo, ukunwebeka kwentengo yokuhlinzeka, ukunwebeka kwenzuzo yesidingo, kanye nokunwebeka okuwela, singahlola ngokunembile izimpendulo zemakethe ezinguqukweni eziguquguqukayo ezithile. Lolu lwazi lubaluleke kakhulu ekwenzeni izinqumo zomnotho , kokubili emazingeni omuntu ngamunye kanye nawenhlangano, futhi lunganikeza ukuqonda okujulile ngendlela izimakethe ezisebenza ngayo.
