Kev xav nkhaus vs Supply Curve
Kev xav tau thiab kev muab khoom yog cov ntsiab lus tseem ceeb hauv kev kawm txog kev lag luam uas muaj feem cuam tshuam rau ib leeg. Kev xav tau saib ntawm tus neeg yuav khoom sab, thiab cov khoom muag saib ntawm tus neeg muag khoom sab. Qhov kev thov thiab cov khoom siv nkhaus yog cov duab sawv cev ntawm txoj cai lij choj ntawm kev thov thiab kev cai lij choj ntawm kev xa khoom thiab ua kom pom tias qhov ntau npaum li cas thiab qhov xav tau hloov pauv nrog cov nqi hloov pauv. Cov kab lus hauv qab no muab cov ntsiab lus ntawm kev xa khoom thiab kev xav tau dav dav thiab piav qhia qhov sib txawv ntawm qhov kev thov thiab cov khoom siv nkhaus.
Kev xav nkhaus
Kev xav tau txhais tau tias yog lub siab xav yuav khoom thiab kev pabcuam txhawb nqa los ntawm kev muaj peev xwm thiab txaus siab them tus nqi. Txoj cai ntawm kev thov yog ib lub tswv yim tseem ceeb hauv kev lag luam uas saib kev sib raug zoo ntawm tus nqi thiab qhov xav tau ntau. Txoj cai lij choj ntawm kev thov hais tias raws li tus nqi ntawm cov khoom nce qhov kev thov rau cov khoom yuav poob, thiab raws li tus nqi ntawm cov khoom poob, qhov kev thov rau cov khoom yuav nce ntxiv (piv txwv tias lwm yam tsis suav nrog). Qhov kev thov nkhaus yog cov duab sawv cev ntawm txoj cai ntawm kev thov.
Qhov kev thov nkhaus tuaj yeem kos rau ntawm daim duab qhia tus nqi ntawm y axis, thiab kom muaj nuj nqis ntawm x axis. Qhov kev thov nkhaus yuav nqes nqes los ntawm sab laug mus rau sab xis vim nws qhia txog kev sib raug zoo uas muaj nyob nruab nrab ntawm tus nqi thiab qhov xav tau. Piv txwv li, yog tias tus nqi ntawm cov khoom yog $ 10, qhov ntau xav tau yuav yog 100. Raws li tus nqi nce mus rau $ 20, kev thov yuav poob mus rau 50, thiab thaum tus nqi nce ntxiv mus rau $ 30 thov yuav poob rau 25. Plotting cov ntsiab lus ntawm daim duab. yuav qhia ib tug downward sloping thov nkhaus ntawm sab laug mus rau sab xis.
Supply Curve
Supply yog tus nqi ntawm cov khoom thiab cov kev pab cuam uas tus neeg tsim khoom txaus siab muab rau qhov chaw ua lag luam rau tus nqi. Kev xa khoom yuav qhia txog kev sib raug zoo ntawm qhov ntau uas tus neeg tsim khoom txaus siab muab thiab tus nqi uas cov neeg tsim khoom txaus siab muag lawv cov khoom. Txoj cai lij choj ntawm kev muab khoom hais tias qhov ntau npaum li cas yuav nce ntxiv raws li tus nqi ntawm cov khoom / kev pabcuam nce, thiab cov khoom xa tuaj yuav txo qis raws li tus nqi ntawm cov khoom poob.
Cov khoom siv nkhaus graphically sawv cev rau txoj cai ntawm kev muab khoom, qhov twg y axis yuav yog tus nqi thiab x axis yuav muab ntau npaum li cas. Cov khoom siv nkhaus slopes upwards los ntawm sab laug mus rau sab xis, raws li nws qhia ib tug ncaj qha kev sib raug zoo ntawm tus nqi thiab kom muaj nuj nqis. Yog tias tus nqi ntawm cov khoom yog $ 5 qhov khoom yuav yog 50 units, thaum tus nqi nce mus rau $ 10 khoom yuav nce mus rau 100 thiab lwm yam. Yog tus nqi poob rau $2 mov yuav poob mus txog 20 units.
Kev xav tau vs Kev xa khoom nkhaus
Kev xav tau thiab kev xa khoom yog cov ntsiab lus zoo sib xws rau ib leeg hauv kev kawm txog kev lag luam. Txawm li cas los xij, txawm tias lawv txoj kev sib raug zoo, ob lub tswv yim sib txawv heev. Kev thov nkhaus saib ntawm cov neeg siv khoom sab rau kev yuav khoom thiab kev pabcuam, thiab cov khoom siv nkhaus saib ntawm tus tsim khoom rau kev muag khoom thiab kev pabcuam.
Rau qhov xav tau, tus nqi thiab qhov ntau muaj kev sib raug zoo (txav mus rau qhov tsis sib xws) raws li tus nqi nce qhov xav tau poob thaum tib neeg yuav tsawg dua ntawm tus nqi siab. Raws li kev muab khoom, tus nqi thiab qhov ntau muaj kev sib raug zoo ncaj qha qhov chaw muab khoom nce thiab tus nqi nce qhov twg tus neeg tsim khoom yuav muab ntau dua ntawm tus nqi siab dua. Lub ntsiab lus ntawm ob qho tib si mov thiab kev xav tau nkhaus sib ntsib yog qhov sib npaug ntawm qhov kev thov sib npaug rau cov khoom.
Summary:
• Kev thov nkhaus saib ntawm cov neeg siv khoom sab rau kev yuav khoom thiab kev pabcuam, thiab cov khoom siv nkhaus saib ntawm tus tsim khoom rau kev muag khoom thiab kev pabcuam.
• Qhov kev thov nkhaus yuav nqes nqes los ntawm sab laug mus rau sab xis vim nws qhia txog kev sib raug zoo ntawm tus nqi thiab qhov xav tau.
• Cov khoom siv nkhaus nqes nce ntawm sab laug mus rau sab xis, raws li nws qhia txog kev sib raug zoo ntawm tus nqi thiab qhov ntau.
