Yuav ua li cas yog tus nqi elasticity ntawm kev thov

Ib tug ntawm cov tswv yim ntawm kev khwv nyiaj txiag - qhov kev thov yog nyob ntawm ntau yam, uas muaj xws li cov theem ntawm tus nqi rau cov khoom, neeg khwv tau nyiaj, cov khoom uas zoo, thiab cov neeg siv tastes. Tab sis nws yog feem ntau zoo qhov kev thov nyob rau tus nqi thiab theem. Cov qhov taw qhia, hu ua lub "nqi elasticity ntawm kev thov", captures kev thov hloov nyob rau hauv raws li ib tug txo los yog ib qho kev nce ntawm ib tug rau ib xees ntawm tus nqi.

Elasticity ntawm kev thov qhia rau saib tus nqi. Lub tuam txhab, yog li ntawd, yog lub feem ntau muaj kev vam meej chav kawm ntawm nws pricing txoj cai yog li ntawd nws yuav coj ntau dua economic cov kev pab cuam. Cov ntaub ntawv tau raws li ib tug tshwm sim pub rau mus ntsib cov neeg teb, teem cov kev taw qhia ntawm ntau lawm, nyob rau hauv thiaj li yuav zoo teb rau cov kev hloov noj qhov chaw nyob rau hauv lub lag luam thiab kho nyob rau hauv lub sib qhia.

Nyob rau hauv kev xam xyuas qhov kev thov nyob rau hauv uas tsis muaj coefficient ntawm elasticity siv tus ntoo khaub lig elasticity thiab ncaj. Yuav kom txiav txim seb lub caij nyoog kawg no, xam tus piv ntawm cov kev hloov nyob rau hauv lub ntim ntawm kev thov rau cov kev hloov nyob rau hauv tus kwv tij tus nqi ntawm cov khoom. Qhov no qhia tso cai rau koj mus muab cov feem pua hloov nyob rau hauv kev thov nyob rau hauv nce mus nce los nqi ntawm cov khoom los ntawm ib feem pua. Qhov no zoo tshaj muaj ob peb lub ntsiab. Yog li ntawd, yog hais tias nws txoj kev infinity, qhov no txhais tau tias, ua ke nrog ib tug txo nyob rau hauv neeg thov nce nqi rau cov khoom, tab sis, yog hais tias tus nqi sawv, ces tau txais kev pab kiag li tso tseg lub purchase. Yog hais tias tus piv yog ntau tshaj ib tug, ces qhov kev thov yog loj hlob sai heev thiab yog ua ntej ntawm tus nqi tsub kom. Thaum tus piv yog tsawg tshaj li sib sau, cov rov qab qhov teeb meem no. Yog hais tias qhov ncaj nqi elasticity ntawm kev thov yog sib npaug zos rau ib tug, tus nqi thiab kev thov kev loj hlob yog nyob rau tib lub pace. Thaum qhov ntsuas no yog sib npaug zos rau zero, thov tsis cuam tshuam rau cov nqi ntawm cov khoom.

Nyob rau hauv paub qhov coefficient ntawm tus ntoo khaub lig-nqi elasticity ntawm kev thov, muaj ib tug sib piv ntawm cov kev hloov hais txog cov neeg txheeb ze volume ntawm qhov kev thov rau ib qho khoom, qhov twg ib tug feem pua ntawm tus nqi hloov nyob rau lwm yam. Qhov no xam kuj muaj ob peb lub ntsiab. Yog li ntawd, yog hais tias tus piv yog ntau tshaj pes tsawg, ces cov piv khoom yog ob leeg interchangeable. Yog hais tias lub zog tus nqi rau butter, nws yuav ua rau kom qhov kev thov, piv txwv li, zaub roj. Yog hais tias qhov zoo tshaj yuav constituting tus ntoo khaub lig-nqi elasticity ntawm kev thov yog tsawg tshaj li xoom, ces tus piv khoom yog complementary. Piv txwv li, thaum roj nqi yog nce, muaj ib tug poob rau hauv kev thov rau lub tsheb. Yog hais tias lub coefficient yog sib npaug zos rau zero, cov khoom uas tsis nyob rau ntawm txhua lwm yam. Qhov ntawd yog tus nqi hloov rau ib tug tsis muaj feem xyuam rau qhov kev thov rau lwm yam.

Rau qhauj koom nyob rau hauv zus tau tej cov khoom, nws yog ib qho tseem ceeb kom paub tias elasticities. Tom qab pricing ua khoom uas feem ntau yog tsim los ntawm cov nqi ntawm ntau lawm, yog li cov ua nqi ntawm qhov khoom yog tsim tsis tsuas mus rau compensate rau lawv, tab sis kuj coj profit rau lub chaw tsim tshuaj paus. Yog li ntawd, mus kawm cov nqi elasticity ntawm kev thov vim hais tias nws yog ib qho tseem ceeb uas lub pricing zoo ntawm lub enterprise tau raug xaiv kom raug.

Cov chaw tsim tshuaj paus yuav tsum coj mus rau hauv tus account uas lub elasticity ntawm kev thov rau nws cov khoom tej zaum yuav txawv los ntawm lub elasticity ntawm kev thov nyob rau hauv kev ua lag luam. Tus thawj qhia yuav yeej ib txwm muaj ntau tshaj li qhov thib ob, tsuas yog nyob rau hauv cov mob uas lub chaw tsim tshuaj paus ntawm cov khoom yog ib tug monopolist. Thaum xam cov nqi elasticity yog tsis tsim nyog rau tso xws li ib qho tseem ceeb raws li cov kev sib tw. Yog li ntawd, thaum xam xyuas cov coefficient ntawm elasticity ntawm kev thov yog siv zauv qauv yuav siv sij hawm mus rau hauv tus account lub tus kheej kev ntawm tus thawj coj.

Koj muaj peev xwm txheeb xyuas cov nyiaj tau los elasticity ntawm kev thov. Yog hais tias tau txais kev pab muaj ntau zog nyiaj los ntawm ib feem pua, qhov kev nce thiab cov kev thov los ntawm cov tib tug nqi. Los ntawm no nws hais ntxiv hais tias lub elasticity yog sib npaug zos rau ib tug.

Cov khoom hais no yuav qhia tau tias elastic thov - lub muaj zog ntawm tus neeg txaus siab rau tej pab pawg ntawm cov khoom nyob rau hauv raws li cov kev hloov nyob rau hauv lawv cov nqi theem.
