Puas yog cov nqi them nqi se txiav tawm?
(1) Feem ntau. Tsuas yog rau lub hom phiaj ntawm kev txiav txim siab tus nqi ntawm cov nuj nqis uas yuav raug txiav tawm hauv ib lub sijhawm, cov nqi no raug kho raws li lawv kho cov txiaj ntsig ntawm cov nuj nqis. Txhawm rau ua qhov no, tus tsim tawm kho cov nqi zoo li lawv txo tus nqi ntawm cov nuj nqis .
Thaum cov nqi hluav taws xob marginal txo qis tag nrho cov nqi hluav taws xob?
(b) Marginal utility, los ntawm kev txhais, qhia txog kev hloov pauv ntawm tag nrho cov nqi hluav taws xob. Yog li kev siv nyiaj marginal txo qis nrog kev siv ntau ntxiv, dhau los ua xoom thaum tag nrho cov nqi hluav taws xob yog qhov siab tshaj plaws, thiab yog qhov tsis zoo thaum tag nrho cov nqi hluav taws xob poob .
