Allocative efficiency txhais tau hais tias kev sib xyaw ua ke ntawm cov khoom lag luam uas ib pawg neeg tsim khoom sawv cev yog kev sib xyaw ua ke uas tib neeg xav tau. Rau piv txwv , feem ntau ib lub zej zog nrog cov neeg hluas muaj kev nyiam rau kev tsim kev kawm, tshaj li kev tsim kho kev noj qab haus huv.
Yog li ntawd, dab tsi yog txhais los ntawm allocative efficiency?
Txhais : Allocative efficiency yog lub tswv yim kev lag luam uas tshwm sim thaum cov khoom tsim tawm yog ze li sai tau rau tus nqi marginal. Hauv qhov no, tus nqi uas cov neeg siv khoom txaus siab them yog yuav luag sib npaug ntawm cov nqi hluav taws xob uas lawv tau txais los ntawm qhov zoo lossis kev pabcuam.
Tsis tas li ntawd, koj ua li cas qhia txog kev faib ua haujlwm zoo? Allocative efficiency yog theem ntawm cov zis qhov twg tus nqi ntawm ib tug zoo los yog kev pab cuam yog sib npaug zos rau marginal nqi ntawm ntau lawm. Nws tuaj yeem ua tiav thaum cov khoom thiab / lossis cov kev pabcuam tau muab faib ua qhov zoo, thiab thaum lawv cov nqi qis thiab cov nqi hluav taws xob sib npaug sib npaug.
Nyob rau hauv txoj kev no, dab tsi yog ib qho piv txwv ntawm kev ua tau zoo?
Ib qho kev lag luam uas ua haujlwm nrog nws ntau lawm muaj peev xwm frontier tau maximized nws ntau lawm efficiency . Hauv qhov yooj yim piv txwv , kev lag luam tsim ob yam khoom - tsheb thiab tsev. Yog tias kev lag luam tab tom tsim tsheb thiab tsev nyob raws li tus ciam teb no, nws tau ua kom tiav nws ntau lawm efficiency.
Dab tsi ua rau allocative efficiency?
Muab faib inefficiency tshwm sim thaum tus neeg siv khoom tsis them nyiaj muaj txiaj ntsig nqe. Ib muaj txiaj ntsig tus nqi yog ib qho uas tsuas yog them cov nqi ntawm cov khoom tsim tawm hauv kev muab cov khoom zoo lossis kev pabcuam. Allocative efficiency tshwm sim thaum lub tuam txhab tus nqi, P, sib npaug ntxiv (marginal) tus nqi ntawm cov khoom, MC.

Dab tsi yog qhov piv txwv piv txwv hauv kev txheeb cais?
Nyob rau hauv kev txheeb cais, sampling bias yog ib tug bias nyob rau hauv uas ib tug piv txwv yog sau nyob rau hauv xws li ib tug txoj kev uas ib co tswv cuab ntawm cov neeg npaj muaj ib tug tsawg sampling probability tshaj lwm tus
Dab tsi yog rau lub tshuab yooj yim thiab cov piv txwv ntawm lawv yog dab tsi?
Cov no yog rau lub tshuab yooj yim: cov nplais, lub log thiab lub qag, qib, lub dav hlau inclined, ntsia hlau, thiab lub log
Allocative thiab productive efficiency nyob qhov twg?
Tag nrho kev ua haujlwm txhais tau tias tsim tau qhov 'txoj cai' (Allocative efficiency) tus nqi ntawm 'txoj kev' (kev ua haujlwm zoo). Allocative efficiency tshwm sim qhov twg tus nqi yog sib npaug rau marginal nqi (P = MC), vim hais tias tus nqi yog tib neeg kev ntsuas ntawm tus txheeb ze tus nqi ntawm cov khoom ntawm cov paj los yog nws cov txiaj ntsig marginal
Dab tsi yog qhov txawv ntawm technical efficiency thiab economic efficiency chegg?
Dab tsi yog qhov txawv ntawm technical efficiency thiab economic efficiency? a. Technical efficiency nyob rau hauv ntau lawm txhais tau hais tias tsawg inputs li sai tau yog siv los tsim ib tug muab tso zis. economic efficiency txhais tau hais tias siv txoj kev uas tsim ib theem ntawm cov zis ntawm tus nqi qis tshaj
Lub tuam txhab ntiag tug txwv piv txwv yog dab tsi?
Ib qho piv txwv ntawm lub tuam txhab ntiag tug txwv feem ntau yog ib lub khw muag khoom hauv zos, xws li lub khw lossis tsev noj mov, uas tsis muaj lub tebchaws nyob. Ib qho piv txwv ntawm lub tuam txhab kev txwv tsis pub tshaj tawm yog ib lub tuam txhab loj xws li cov khw muag khoom muag lossis cov khw noj mov nrog cov koom nrog uas txhua tus tuaj yeem yuav thiab muag
