Nqe Elasticities Raws li Linear Demand Curve
Tus nqi elasticity ntawm xav tau sib txawv ntawm cov khub sib txawv ntawm cov ntsiab lus raws li ib tug linear xav tau nkhaus . Tus nqi qis dua thiab ntau dua qhov xav tau, qhov qis dua tus nqi ntawm tus nqi elasticity ntawm xav tau.
Yog li ntawd, vim li cas elasticity hloov raws li qhov xav tau nkhaus?
Hais elasticity (ntawm xav tau ) muab qhov feem pua hloov nyob rau hauv kom muaj nuj nqis nyob rau hauv teb rau ib feem pua hloov hauv nqe. Raws li qhov xav tau ntau ntxiv raws li qhov xav tau nkhaus , qhov feem pua nce hauv kom muaj nuj nqis uas ua rau ib feem pua ntawm cov nqi yuav txo.
Ib yam li ntawd, puas yog linear thov nkhaus muaj qhov elasticity tas li? Feem ntau, a nkhaus yog elastic yog nws yog tiaj thiab ntau inelastic yog tias nws yog ntau verticle. Txawm li cas los xij, qhov no tau ua me ntsis yuam kev. Txawm nyob rau ib kab tawm (txoj cai) xav tau los yog khoom siv nkhaus , cov elasticity yog tsis yog tas li rau tag nrho nkhaus.
Ua raws li qhov xav tau, vim li cas qhov elasticity ntawm kev thov siab dua raws li qhov xav tau ntawm txoj kab ncaj nraim?
Nrog ib linear xav tau , cov elasticity yog heev siab thaum tus nqi yog siab thiab nws yog ib sab ntawm xoom thaum tus nqi qis. Qhov no yog vim qhov elasticity qhia txog qhov piv ntawm feem pua variations thiab a linear xav tau implies ib tug tas li ratio ntawm variations nyob rau hauv ntau ntau.
Dab tsi yog linear thov nkhaus txhais li cas?
Kev txheeb xyuas. A linear xav nkhaus yog qhov graphical sawv cev ntawm kev sib raug zoo ntawm tus nqi ntawm ib qho zoo thiab qhov ntau ntawm cov neeg siv khoom zoo txaus siab them rau qee tus nqi ntawm ib lub sijhawm.

Dab tsi yog daim ntawv thov ntawm elasticity ntawm kev thov?
Kev thov ntawm Tus Nqi Elasticity ntawm Qhov Xav Tau Cov thawj tswj hwm pej xeem pom qhov tsis txaus ntseeg hauv kev thov luam yeeb, yog li lawv pom nws muaj txiaj ntsig los nce se loj. Kev ntsuas tus nqi hloov pauv ntawm qhov xav tau pab cov tswj hwm pej xeem txhawm rau txhim kho cov nyiaj hli yam tsawg kawg kom ua kom muaj txiaj ntsig zoo rau ob qho tib si nrog rau kev ua haujlwm
Vim li cas tus nqi marginal nkhaus cov khoom nkhaus hauv kev sib tw zoo meej?
Lub marginal nqi nkhaus yog ib qho khoom siv nkhaus nkaus xwb vim tias kev sib tw zoo kawg nkaus sib npaug tus nqi nrog tus nqi marginal. Qhov no tshwm sim tsuas yog vim tus nqi sib npaug ntawm cov nyiaj tau los marginal rau lub tuam txhab kev sib tw zoo kawg nkaus
Vim li cas MR nkhaus tsawg dua qhov xav tau nkhaus?
A. Vim hais tias tus monopolist yuav tsum txo tus nqi ntawm txhua chav nyob rau hauv thiaj li yuav muag ntxiv units, marginal nyiaj tau los tsawg dua tus nqi. Vim tias cov nyiaj tau los marginal tsawg dua tus nqi, cov nyiaj tau los ntawm cov nyiaj tau los yuav nyob hauv qab qhov kev xav tau
Puas yog qhov kev thov rau iPhones nqi inelastic lossis elastic Vim li cas cov nyiaj tau los elasticity siab lossis qis?
Li no, nws tuaj yeem hais tias Iphone yog cov nyiaj tau los elastic, vim tias muaj tus nqi ntau dua 1. Nws yog ib qho zoo vim tias qhov feem pua nce ntawm qhov xav tau ntau dua qhov feem pua nce hauv cov nyiaj tau los. Kev nce hauv cov nyiaj tau los yuav ua rau muaj kev xav tau zoo li no
Yuav ua li cas economists kwv yees los ntawm kev tsim ib qho kev thov nkhaus thaum twg qhov kev thov nkhaus yuav pab tau?
Raws li tus nqi ntawm qhov zoo lossis kev pabcuam txo qis tib neeg feem ntau xav yuav ntau ntawm nws thiab rov ua dua. Vim li cas aneconomist tsim kev lag luam xav tau nkhaus? Ua piv txwv yuav ua li cas tib neeg yuav hloov lawv cov kev yuav khoom thaum tus nqi hloov. Daim ntawv cog lus ntawm tus nqi thiab cov khoom lag luam
