　　Thiscircumstancereceivesmoredistinctformandemphasisinthecaseofproductiongoodscapableofmanyandvariousemployments。Herecaremustbetakentochoosethoseemploymentswhichwillprovethemosteconomicallyefficient，bothasregardskindandamount。Circulatingcapitalorlabourpowerdevotedtoanyoneproduction，istherebyabsolutelywithdrawnfromallothers；thesameistrueoffixedcapital，andevenofunconsumableland，duringtheperiodoftheproductiontowhichtheyaredevoted。Inconsiderationofthisfactthedevotionofmeansofproductiontoindividualundertakingmustalwaysbewellconsidered。Itisnecessary，forthisend，thatthemanwhoresolvesonthemakingofonespecialproduct，shouldformanexactideaofthevalueofalltheotherproductswhosemanufactureistherebyrenderedimpossible。Buthowcanthisbedone？Itisdonebytakingaccountofthevalueoftheircommoneconomicfactorsofproduction。Inthesefactorsthevalueofall“cognate“products，withoutexception，isincorporated。
　　Productivevalue，consequently，occupiesapositionofmentionamongthewholecircleofcognateproducts。Wheneverthevalueofanyclassofproductsfallsorrises，andtherebyeithertheextensionorthelimitationofotherbranchesofproductionisdemanded，1*theeffectisfirstcommunicatedtoproductivevalue，andisthenpassedonfromproductivevalue。Theproductsandthevalueoftheproductsadjustthemselves，ineachindividualcase，totheproductivevalue，andtheproductivevalueindicatesthelimitofproductioncommontoall。
　　Inthiswaywereachthepointofviewfromwhichproductiongoodsareconceivedofascosts。Thefirstelementinitisthattheproductiveemploymentfiguresasoutlay，assacrifice，asloss；thesecondisthat，invirtueofthis，attentioniscalledtotheequalisationofseveralconnectedproductions。Tosaythatanykindofproductioninvolvescost，simplyimpliesthattheeconomicmeansofproduction，whichcoulddoubtlesshavebeenusefullyemployedinotherdirections，areeitherusedupinit，oraresuspendedduringit。Costsareproductiongoodswhenthesearedevotedtooneindividualemployment，and，onaccountoftheircapacityofbeingotherwiseemployed，taketheshapeofoutlay，expenditure。2*Themeasureforestimatingcostsisalwaystheproductivemarginalutility，asitisfoundonconsiderationofalltheemploymentseconomicallypermissible。

　　FoundationoftheLawofCostsThevalueofcostsdeterminesthevalueofproductsintwoways。Ingeneralitdeterminesitindirectly，byregulatingthesupplyproduced；but，inindividualcases，itdeterminesitdirectlybycommunicatingtheamountofitsownvaluewithoutanyintermediary。
　　First:asregardstheindirectactionofcosts。Inthevalueofthecostsisexpressedtheexpectationofthegreatestpossiblereturnfromproduction。Inordertofulfilthisexpectation，therelationbetweentheamountsofallcognateproductsturnedoutmustbewellweighedandproportioned。Iftoomuchbeproducedinanyonedirectionalosswillhavetobeborneelsewhere，whichwillbemoresensiblethanthegainresultingfromtheover-production。Iftoolittlebeproducedinanyonedirectionasimilarlosswillbefelt，whichitwillbeimpossibletomakegoodbyover-productionelsewhere。
　　Whethertoomuchortoolittlehasbeenproducedisseenexactlyinthevalue。Ifthevalueofproducts——asitresultsfromtheequationbetweensupplyanddemand——islessthanthatofthecosts，toomuchhasbeenproduced；thecostswhichshouldhavebroughtforthproductshavinghighervaluehavebroughtforthonlygoodshavinglessvalue。Wherethevalueoftheproductexceedsthatofthecosts，toolittlehasbeenproduced——withoneexceptionwhichwillbementionedshortly；——thecostshavenotbeenemployedentirelyinbringingforthproductsofthehighestvaluetheveryanticipationofwhichgavethecoststheirvalue。Ifproducts，then，aretobeproducedneitherovernorundercosttheymustbeproducedexactlyatcostvalue，iftheyaretofindthemosteconomicallyadvantageousdistributionofproduction。
　　Ifweaskwhyproductsthusproduced——neitherundernorovercosts——havevalue，andwhytheyhavedefiniteamountsofvalue，weshalldoubtlessfindthattheyhavethemselvesalonetothankforit。Theycreateitoutoftheirutility，takingintoconsiderationtheamountsproduced。Thecircumstancethatcostsofacertainvaluehavebeenexpendedinmakingthem，isofnoconsequenceasregardstheirvalue。Thecostvaluedoesnotdeterminetheusevalue；theusevalueexistsofitself，andsanctionsthecostvalue。
　　Second:asregardsthedirectactionofcosts。Undercertaincircumstancesitiseconomicallypermissibletoproducethingswhoseusevalueexceedstheircostvalue，whiletheymust，nonetheless，beestimatedattheircostvalue。Thisdirectactionisthemoststrikingofthetwo。Assumethattheamountofcostsnecessaryforanarticlehasthevalueof6，andthatthefirstarticleproducedhasausevalueof10，whiletheusevalueofasecondarticlewouldamounttoonly1compareBookI。chap。ivandBookIII。chap。viii:theproductionmustbeconfinedtoonearticle。Howisittobevalued？Thiswilldependuponcircumstances。Inamomentofextremedangeraweaponwillbeestimatedaccordingtoitsusevalue。Butsupposeamantobeleisurelypreparingandequippinghimselfforanadventuresomejourney，hewillnotthinkofvaluingthebestofweaponsmorehighlythanthematerialsandlabouravailableforthepurposeofproducingandreproducingthem。Thelossoftheweaponcanalwaysbemadegood——supposingonehasthenecessaryleisureandmeansforitsreproduction——byasacrificeincosts，theamountofwhichiscertainlylessthantheimportancepossessedbytheweaponitselfinamomentofurgentneed。Agoodhavingausevalueequalto10，andacostvalueequalto6，mustbeestimatedat6，solongasitsreproductionispossibleandthesatisfactionofwantisnotprejudicedbythedelay。

　　For，as，intheonecase，themarginaluseisreallytheonlyusethreatened，so，intheother，thecostvalueistheonlyvaluethreatened。Hereisanewapplicationofthemarginallaw。
　　Casesofthekindjustdescribedattractparticularnoticeonaccountofthefactthattheinfluenceofcostsuponthevalueofproductsisindependentofamountsproduced。Ifthecostvalue，intheexamplejustgiven，risefrom6to9，orfallto2，oneproductonlywillbeproduced，anditsvaluelikewisewillfollowthechangesofthecostvalue，andriseto9orfallto2，withouttheamountsproducedbeingchanged。Ricardo，withthekeennessofobservationpeculiartohim，pointedtotheconsiderationofthoseinstances，inwhichthevalueoftheproductadjustsitselftothecostvaluewithoutanychangeofamounts，asaveryimportantonefromthepointoftheory。Asamatteroffactitisso，althoughRicardowaswrongintheplacehegaveit。Hewishedtoprovefromitthatcostsarefundamentallyanindependentsourceofvalue，whereas，asamatteroffact，itprovessimplythatcostsmay，incertainisolatedcases，directlydeterminetheamountofthevalueofproducts。Itis，however，chieflydecisiveinthatitgivesusaninsightintotheconnectionsoftheprocessofvaluationsuchascouldscarcelybeobtainedotherwise。Itgivesus，indeed，themostunequivocalandumdeniableapplicationofthemarginallawthatitispossibletofindanywhere。
　　Moreover，eveninthiscase，thefactthatcostshavebeenexpendedisofnoimportanceasregardsthevalueofproducts。
　　Thedecisivecircumstanceis，thatcostscouldagainbeexpended，andsecureahigherutilityatalesssacrificeofutility。1*

　　TheLawofCostsandtheGeneralLawofValueIfthestatementofthelawofcostsjustlaiddownbecorrect，therecanbenodoubtregardingitsrelationtothegenerallawofvalue。
　　Betweencostsandutilitythereisnofundamentalopposition。
　　Costsaregoodsvalued，intheindividualcase，accordingtotheirgeneralutility。Theoppositionbetweencostsandutilityisonlythatbetweentheutilityoftheindividualcase，andutilityonthewhole。Whoeverthinksof“utility“withoutthinkingof“costs，“simplyneglects，intheutilityofoneproduction，theutilityoftheothers。Andwhoeverproduces，intheindividualcase，attheleastcost，produces，onthewhole，withthehighestutility，inasmuchashethussavesalltheopportunitiesofutilitypossible，andconsequentlyinthelongrunutilisesalltheseopportunitiestotheutmostextent。
　　Thuswherethelawofcostsobtains，utilityremainsthesourceofvalue。Morethanthis，marginalutilityremainsthemeasureofvalue。Theonlythingisthatutilityandmarginalutilityarenolongerdeterminedinaone-sidedwaywithinthelimitsofeachparticulargroupofproducts，butovertheentirefieldofcognateproduction。Overthisfielditisalwaysthecommonproductivemarginalutilitythatdecides。Theresultoftheproductivecombination10a10b10cpossessesthecommonmarginalutilityofallproductivegoodsoftheclassAtentimes，andsowiththeclassesBandC。Itconsequentlystandsinadefiniteratioofvaluetotheproductresultingfrom10a20b10c，andthisratiocorrespondstothegenerallawofvalue，accordingtowhichseparatepartsofastockaretobevaluedbymultiplyingthenumberofitemsbythemarginalutility。Evenproductswhich，inoutwardappearanceanddestination，areentirelydifferentfromoneanother，iftracedbacktotheproductiveelementsoftheirmanufacturecomeultimatelyintothesamevaluerelationsasdotheseparatepartsofastock。A

　　Thisstatementwouldbeimperfectifwedidnotaddthatthelawofcostsasregardsproductsisbyfarthemostusualformassumedbythegenerallawofvalue。Productsofalmosteverykindarecontinuallybeingreproduced，andconsequentlytheirvaluemustcontinuallybedecidedbycomparingtheamountoftheproductivesupplieswiththeamountoftheproductivedemand。Thevastmajorityofchangesinvalueareoccasionedbythechangeswhichoccurinthecomingforwardofproductiongoodsorintheirproduction，wheretheyarethemselvesobjectsofproduction，asalsobytechnicalchanges，orchangesintheconditionsofproductionwhichmakethequantityofcostsnecessarytoproducethegoodsgreaterorless。Thusithappensthatvariationsinthevalueofproductsaretraceable，inthemajorityofcases，tosomecausewhichistobefoundinproductiongoods。Evenincaseswherethechangeofvaluefirstarisesinthedemandandintheproducts，theeffectofthiscircumstancecommunicatesitself，throughthemediumofthecostgoods，tothecognateproducts，andcausestheirvaluetoriseorfall。Aproductwhichis“cognate“withahundredothers，will，inallprobability，beaffectedahundredtimesbychangesintheirsupplyanddemandrelations，foroncethatitisaffectedbyachangeinitsownrelations；andalltheseinfluencesarecommunicatedtoitfromoutsidethroughthecostvalue。Andthusitisthatchangesinanysinglesupplyanddemandmustpasswithoutleavinganytrace，unlesstheychancetobeexceedinglycomprehensive，andare，therefore，capable，asagainstthesupplyanddemandoverthewholecircleofcognateproduction，ofdisturbingthedeterminingmarginalutility。
