Elasticity ntawm Demand vs Elasticity ntawm Supply
Zoo ib yam li lub ntsiab lus ntawm kev nthuav dav ntawm cov roj hmab band, elasticity ntawm kev thov / khoom xa tuaj yog hais txog qhov hloov pauv hauv X (uas tuaj yeem yog txhua yam xws li tus nqi, nyiaj tau los, tus nqi raw khoom, thiab lwm yam) tuaj yeem cuam tshuam rau qhov xav tau ntau. los yog kom muaj nuj nqis. Hauv nqe elasticity ntawm kev thov (PED) thiab tus nqi elasticity ntawm cov khoom siv (PES), peb saib seb qhov kev hloov pauv ntawm tus nqi tuaj yeem cuam tshuam rau qhov xav tau ntau npaum li cas lossis cov khoom siv. Cov tshooj no muaj cov ntsiab lus meej ntawm PED thiab PES thiab qhia txog lawv qhov zoo sib xws thiab qhov sib txawv.
YElasticity of Demand yog dab tsi?
Tus nqi elasticity ntawm kev thov qhia tau hais tias qhov kev hloov pauv hauv kev thov tuaj yeem tshwm sim nrog qhov hloov me ntsis ntawm tus nqi. Nqe elasticity ntawm kev thov yog xam los ntawm cov qauv hauv qab no.
PED=% hloov pauv ntawm qhov xav tau / % hloov pauv ntawm tus nqi
Muaj ntau qib ntawm elasticity nyob ntawm seb qhov xav tau npaum li cas yog hloov ntawm tus nqi. Yog tias PED=0, qhov no qhia tau hais tias qhov xwm txheej zoo kawg nkaus uas qhov kev thov yuav tsis hloov txhua yam nrog kev hloov pauv ntawm tus nqi; piv txwv yog cov khoom tsim nyog, cov khoom siv ntxiv. Yog tias PED 1, qhov no qhia tau hais tias tus nqi elastic thov qhov kev hloov me me ntawm tus nqi yuav ua rau muaj kev hloov pauv loj hauv qhov xav tau; piv txwv yog cov khoom kim heev, cov khoom siv hloov pauv. Thaum PED=1, qhov kev hloov pauv ntawm tus nqi yuav muaj qhov sib npaug ntawm qhov xav tau; qhov no hu ua unitary elastic.
Ntau yam tuaj yeem cuam tshuam rau PED xws li muaj cov khoom siv hloov pauv (xav tau ntau dua elastic nrog cov hloov pauv ntau dua li tam sim no cov neeg siv khoom tuaj yeem hloov mus rau butter yog tias tus nqi ntawm margarine nce), seb cov khoom puas yog qhov tsim nyog (xav tau inelastic) lossis khoom kim heev (xav tau elastic), txawm tias qhov zoo yog tus cwj pwm tsim (xws li luam yeeb - kev thov tsis muaj zog), thiab lwm yam.
YElasticity ntawm Kev Muab Khoom yog dab tsi?
Nqe elasticity ntawm cov khoom qhia pom tias qhov kev hloov pauv ntawm tus nqi tuaj yeem cuam tshuam rau qhov ntau npaum li cas. Nqe elasticity ntawm mov yog xam los ntawm cov qauv hauv qab no.
PES=% hloov pauv ntawm qhov khoom muab / % hloov ntawm tus nqi
Thaum PES > 1, mov yog tus nqi elastic (qhov hloov me me ntawm tus nqi yuav cuam tshuam rau cov khoom siv). Thaum PES < 1, cov khoom siv yog tus nqi inelastic (kev hloov pauv loj ntawm tus nqi yuav muaj qhov cuam tshuam me me ntawm cov khoom siv). Thaum PES=0, kev muab khoom yog zoo kawg nkaus inelastic (ib qho kev hloov ntawm tus nqi yuav tsis cuam tshuam rau qhov ntau npaum li cas), thiab PES=infinity yog thaum kom muaj nuj nqis yuav tsis hloov, tsis hais tus nqi.
Muaj ntau yam uas tuaj yeem cuam tshuam rau PES xws li lub peev xwm ntau lawm (muab elastic), muaj cov khoom siv raw (raws li cov khoom tsis txaus, cov khoom tsis muaj zog), lub sij hawm (lub sij hawm ntev dua - cov khoom yog elastic raws li cov khoom siv raw khoom). ruaj muaj sijhawm txaus los kho qhov tseem ceeb ntawm kev tsim khoom thiab nce ntau lawm), thiab lwm yam.
Y
Elasticity ntawm Supply vs Elasticity ntawm Demand
Tus nqi elasticity ntawm kev thov thiab tus nqi elasticity ntawm cov khoom yog cov ntsiab lus zoo sib xws rau ib leeg vim lawv xav txog seb qhov kev thov lossis cov khoom yuav cuam tshuam li cas los ntawm kev hloov pauv ntawm tus nqi. Qhov ob yog, txawm li cas los xij, txawv raws li PED saib seb qhov kev thov yuav hloov pauv li cas thiab PES txiav txim siab seb yuav hloov pauv li cas. Lwm qhov sib txawv loj ntawm elasticity ntawm kev thov thiab elasticity ntawm cov khoom yog qhov kev thov thiab cov khoom lag luam teb txawv rau qhov nce / txo nqi; kev xav tau nce ntxiv thaum tus nqi poob, thiab cov khoom lag luam yuav poob thaum tus nqi poob. Qhov no txhais tau hais tias yog PED yog elastic, tus nqi nce me me yuav ua rau kom muaj nuj nqis ntau thiab yog tias PES yog elastic me me ntawm tus nqi yuav ua rau kom muaj ntau ntxiv.
Summary:
• Nqe elasticity ntawm kev thov thiab tus nqi elasticity ntawm cov khoom yog cov ntsiab lus zoo sib xws rau ib leeg raws li lawv xav txog seb qhov kev thov lossis cov khoom yuav cuam tshuam li cas los ntawm kev hloov pauv ntawm tus nqi.
• Nqe elasticity ntawm kev thov qhia tau hais tias qhov kev hloov pauv hauv kev thov tuaj yeem tshwm sim nrog qhov hloov me ntsis ntawm tus nqi. Nqe elasticity ntawm kev thov yog xam los ntawm, PED=% hloov ntawm qhov ntau xav tau / % hloov ntawm tus nqi.
• Nqe elasticity ntawm cov khoom qhia tau hais tias qhov kev hloov pauv ntawm tus nqi tuaj yeem cuam tshuam rau cov khoom siv. Tus nqi elasticity ntawm kev muab yog xam raws li, PES=% hloov ntawm qhov ntau muab / % hloov ntawm tus nqi.
• Ib qhov sib txawv loj ntawm elasticity ntawm kev thov thiab elasticity ntawm cov khoom yog qhov kev thov thiab cov khoom teb txawv rau qhov nce / txo nqi; Kev xav tau nce ntxiv thaum tus nqi poob, thiab cov khoom yuav poob thaum tus nqi poob.
