Yaqala nini inkolelo-mbono yenzuzo eqhathaniswayo?
Context:Kumodeli yezomnotho, abenzeli banethuba lokuqhathanisa nabanye ekukhiqizeni into ethile uma bekwazi ukukhiqiza leyo nto ngezindleko eziphansi zamathuba noma ngentengo ye-autarky, okusho ukuthi ngezindleko eziphansi eziphansi ngaphambi kokuhweba. Inzuzo eqhathaniswayo ichaza iqiniso lezomnotho lomsebenzi ozuzwa ngokuhweba kwabantu ngabanye, amafemu, noma izizwe, ezivela ekungafani kwezakhiwo zabo zezinto noma inqubekela phambili yezobuchwepheshe. (Inzuzo ephelele, ukuqhathanisa okukhiphayo ngesikhathi (ukusebenza kahle kwabasebenzi) noma ngobuningi bempahla yokufaka (ukusebenza kahle kwezezimali), ngokuvamile kubhekwa njengokuqondakalayo, kepha akunembile kangako <unk> inqobo nje uma izindleko zamathuba okukhiqiza izimpahla emazweni ahlukahlukene, ukuhwebelana okukhiqizayo kungenzeka.)  Ngo-1817, uDavid Ricardo wasungula inkolelo-mbono yakudala yenzuzo eqhathaniswayo ukuze achaze ukuthi kungani amazwe ehlanganyela ekuhwebeni kwamazwe ngamazwe ngisho nalapho izisebenzi zezwe elilodwa zikwazi kangcono ukukhiqiza yonke impahla eyodwa kunezisebenzi zakwamanye amazwe. Wabonisa ukuthi uma amazwe amabili akwazi ukukhiqiza izimpahla ezimbili azibandakanya ezimakethe zamahhala (nakuba kucatshangwa ukuthi inhlokodolobha nomsebenzi akuhambeki emazweni omhlaba), khona-ke izwe ngalinye lizokhulisa ukusetshenziswa kwalo okuphelele ngokuthekelisa impahla elinayo inzuzo eqhathaniswayo ngenkathi ingenisa enye impahla, inqobo nje uma kukhona umehluko ekukhiqizeni umsebenzi phakathi kwala mazwe womabili. Njengoba ibhekwa kabanzi njengenye yezinto ezinamandla kakhulu kodwa eziphikisana nokuqonda kwezomnotho, inkolelo-mbono kaRicardo isho ukuthi inzuzo eqhathaniswayo kunenzuzo ephelele iyona ebangela ingxenye enkulu yokuhwebelana kwamazwe ngamazwe.
Inkolelo-mbono yakudala yenzuzo yokuqhathanisa yasungulwa ngo-1817 nguDavid Ricardo.
