  (3。xii。30)3。Thelastofthethreeinconveniences,liabletoarisefromtheuseofpaper
  money,is
  allalterationinthevalueofthecurrency。
  (3。xii。31)Thisalterationisalwaysanactofthegovernment;andisnotpeculiartopaper
  money。
  Wehavealreadyseen,thatthevalueofametalliccurrencyisdeterminedbythevalueofthe
  metalwhichitcontains。Thatofapapercurrency,therefore,exchangeableatpleasure,eitherfor
  coinsorforbullion,isalsodeterminedbythevalueorthemetalwhichcanbeobtainedforit。
  Thereasonisobvious。Ifthepapershouldatanytimebereducedbelowthevalueofthemetal,
  everypersonwhoheldabanknote,thelessvaluablecommodity,woulddemandforitthemore
  valuablecommodity,themetal。Ifthepromisewere,asinEngland,topayanounceofgoldfor3

  exchange,themoment3l。17s。10—1/2d。inpaperbecameoflessvaluethananounceofgold;
  thatis,themomentgoldroseabovethemintprice。
  (3。xii。32)But,inthesecircumstances,itwouldbetheinterestofthosewhoissuedthenotes
  to
  raisetheirvaluebyreducingtheirquantity。Iftheyendeavouredtomaintainthehighquantity,
  theywouldbecondemnedperpetuallytoissueandperpetuallytowithdraw;becauseeveryman
  whobecamepossessedofanyoftheirnoteswouldhaveaninterestinbringingthembackagain
  forgold;andoneachoftheseoccasionstheissuerswouldsustainaloss。Theywouldissuethe
  notesattherateof3l。17s。10—1/2d。;thatistheywouldreceiveavalueof3l。17s。10—1/2d。
  whentheyissuedthem;butwhentheyreceivedthemback,theywouldbeobligedtopayan
  ounceofgold,for31。17s。10—1/2d。oftheirnotes;andthatouncemightcostthem4l。,orany
  greatersum。
  (3。xii。33)Ifthecurrencyweresuppliedbypaper,withoutcoins,theissuersofthepaper
  could,
  bylesseningitsquantity,andtherebyenhancingitsvalue,reducethepriceofgold。Suppose,by
  thismeans,theyweretoreduceitto3l。perounce。Theymightfilltheircofferswithgoldatthis

  mightthusbekeptverysteadilyconformabletothatofthemetallicstandard。

  only
  bylesseningthequantityofthepreciousmetalcontainedinthem;otherwise,assoonasit
  reducedthevalueofthecoinssufficientlytoaffordamotiveformeltingthem,theywould,as
  fastasissued,disappear。Inthecaseofapapercurrency,itisonlynecessaryforgovernmentto
  withdrawtheobligationtopaymetalforitondemand,whenthequantitymaybeincreased,and
  therebythevaluediminished,toanyamount。
  (3。xii。35)Papercurrencyisissuedwithoutobligationtopayforit,intwoways:either,when
  governmentistheissuer,andrendersitspaperlegaltender,withoutobligationtogivemetalfor

  ofEngland,andgovernmentsuspendsitsobligationtopayforitsnotes。

  of
  thecurrencyinanyparticularcountry,aretwo:first,ariseofprices;secondly,alosstoallthose
  personswhobadarighttoreceiveacertainsumofmoneyof’theoldandundiminishedvalue。
  (3。xii。37)Bythetermprice,Ialwaysunderstandthequantityofmoneywhichisgivenin
  exchange。Analterationinthevalueofmoney,itisobvious,alterstherelativevalueofnothing
  else。Allthings—bread,cloth,shoes,&;c。riseinvalueascomparedwithmoney;butnotone
  of
  themrisesinvalueascomparedwithanyother。
  (3。xii。38)Thisdifferenceofpriceis,initself,ofnoconsequencetoanybody。Themanwho
  has
  goodstosellgetsmoremoneyforthem,indeed;butthismoneywillpurchasehimjustthesame
  quantityofcommodities,ashewasenabledtopurchasewiththepriceheobtainedbefore。The
  manwhohasgoodstopurchasehasmoremoneytogiveforthem;butheisenabledtodoso,by
  gettingjustasmuchmoreforthecommoditieshehastosell。
  (3。xii。39)Withrespecttothesecondeffectofadegradationinthevalueofmoney,itistobe
  observed,thatthereexistsatalltimes,incivilizedcountries,anumberofobligationstopay
  certainsumsofmoneytoindividuals:eitherallatonce,asdebts;orinsuccession,asannuities。
  Itisveryobvious,thattheindividualwhohascontractedwithamantoreceive100l。sustainsa
  losswhenthecurrencyisreducedinvalueandhereceivesnomorethan100l。Itisequally
  obviousthatthepartywhohastopaythesum,isbenefittedtothesameamount。These
  circumstancesarereversedwhenthealterationwhichhastakenplaceisanincreaseofthevalue。
  Inthatcasethemanwhohastopaysustainstheloss;themanwhoreceivespaymentmakesthe
  gain。Theselossesareevilsofgreatmagnitude,asfarasmen’sfeelingsandhappinessare
  concerned;andtheyimplyagrossviolationofthoserulesfortheguardianshipofthat
  happiness,whicharecomprehendedunderthetermjustice。Itis,however,nodestruction,and
  consequentlynoloss,ofproperty。
  (3。xii。40)Humehassupposedthatcertainothereffectsareproducedbytheincreaseofthe
  quantityofmoney。Whenanaugmentationofmoneycommences,individuals,moreorfewer,go
  intothemarketwithgreatersums。Theconsequenceis,thattheyofferbetterprices;andHume
  affirms,thattheincreasedpricesgiveencouragementtoproducers,whoareincitedtogreater
  activityandindustry,andthatanincreaseofproductionistheconsequence。
  (3。xii。41)Thisdoctrineimpliesawantofclearideasrespectingproduction。Theagentsof
  productionarethecommoditiesthemselves,notthepriceofthem。Theyarethefoodofthe
  labourer,thetoolsandmachinerywithwhichheworks,andtherawmaterialswhichheworks
  upon。Thesearenotincreasedbytheincreaseofmoney:howthencantherebemore
  production?ThisisademonstrationthattheconclusionofHumeiserroneous。Itmaybe
  satisfactoryalsotounravelthefallacyofhisargument。
  (3。xii。42)Themanwhogoesfirsttomarketwiththeaugmentedquantityofmoney,either
  raises
  thepriceofthecommoditieswhichhepurchases,orhedoesnot。
  (3。xii。43)Ifnot,hegivesnoadditionalencouragementtoproduction。Thesupposition,
  therefore,
  mustbe,thathedoesraiseprices。Butexactlyinproportionasheraisesprices,hesinksthe
  valueofmoney。Hethereforegivesnoadditionalencouragementtoproduction。
  (3。xii。44)Itwillperhapsbesaid,byaperseveringobjector,thatthemanwhofirstgoesto
  market
  withtheadditionalquantityofmoney,raisesthepriceofthecommoditieswhichheimmediately
  purchases:thattheproducersofthosecommoditiesarethereforeencouragedtogreaterindustry,
  becausethepriceofothercommodities,namely,ofallthosewhichtheyhaveoccasionto
  purchase,hasnotrisen。Butthisheisnotallowedtosay。Thefirstmanwhocamewithan
  additionalquantityofmoneyintothemarkettopurchasethecommoditiesofthoseproducers,
  raisedthepriceofthosecommodities。Andwhy?Becausehecamewithanadditionalquantity
  ofmoney。Theygointothemarkettopurchaseanothersetofcommodities,andgowithan
  additionalquantityofmoney。Theyraise,therefore,thepriceofthosecommodities。Andinthis
  mannerthesuccessiongoeson。Ofallthosecommoditieswithwhichnoadditionalquantityof
  moneyhasyetcomeincontactthepriceremainsunaltered。Themomentanadditionalquantity
  ofmoneycomesincontactwiththem,thepriceisproportionallyraised。
  (3。xii。45)Thewholeofthebusinessofanycountrymaybeconsideredaspracticallydivided
  into
  agreatnumberoflittlemarkets,someinoneplace,someinanother,someofonesortof
  commodity,someofanother:themoney,ofcourse,distributedproportionallyamongthem。Into
  eachofthesemarkets,intheordinarystateofthings,therecomes,ontheoneside,acertain
  quantityofcommodities;ontheothersideacertainquantityofmoney;andtheoneisexchanged
  againsttheother。Whereveranyadditiontakesplaceinthequantityofgoods,withoutany
  additiontothequantityofmoney,thepricefalls,andofnecessityintheexactproportionofthe
  additionwhichhasbeenmade。Ifthisisnotcleartoeveryapprehensionalready,itmaybe
  renderedpalpablebyadducingasimplecase。Supposethemarkettobeaverynarrowone;of
  breadsolely,ontheoneside;andmoneyontheother。Supposethattheordinarystateofthe
  marketis100loavesontheoneside,and100shillingsontheother;thepriceofbread,
  accordingly,ashillingaloaf。Suppose,inthesecircumstances,thatthequantityofloavesis
  increasedto200,whilethemoneyremainsthesame:itisobviousthatthepriceofthebread
  mustfallonehalf,ortosixpenceperloaf。Itwouldnotbeargumenttosay,thatpartofthebread
  wouldnotbesold。buttakenawayunsold。Ifitistakenawayunsold,itisthesamething,with
  respecttothemarket,asifithadneverbeenbrought。Theseconclusions,withrespecttoan
  increaseinthequantityofcommodities,nomandisputes。Isitnotobviousthatthesome
  conclusionsaretruewithrespecttoanincreaseinthequantityoftheoppositecommodity—the
  money?
  (3。xii。46)Alltheconsequences,therefore,ofalteringthevalueofmoney,whetherbyraising
  or
  depressingit,areinjurious。Thereisnosecurity,however,againstit,asitisadeedof
  government,butthatwhichisthesolesecurityagainstthemisdeedsofgovernment;its
  dependenceuponthepeople。Theobligationofpayingthenotesinthemetalisanecessary
  security,wheretheyareissuedatpleasurebyprivatebankers。Iftheywereissuedbya
  governmentstrictlyresponsibletothepeople,itwouldnotbeindispensible;forinthatcasethe

  wasmetallic,mightbesodistinctlyunderstood,thatitwouldnotbetheinterestofthose

  (3。xii。47)Wehavealreadyseen,intreatingofthepropertieswhichrecommendedthe

  subjecttofluctuationofvalue。Theyarenot,however,exemptfromchanges,partlytemporary,
  andpartlypermanent。Thepermanentchangestakeplace,chieflyinconsequenceofachangein

  SectionXIII。TheValueofthePreciousMetalsinEach
  CountryDeterminesWhetherItShallExportorImport(3。xiii。1)Metallicmoney,ormoregenerallyspeaking,thepreciousmetals,arenothing
  more,
  consideredstrictly,andintheiressence,thanthatcommoditywhichisthemostgenerallybought
  andsold,whetherbyindividuals,orbynations。
  (3。xiii。2)Inordinarylanguage,itisimmediatelyacknowledged,thatthosecommodities
  alone
  canbeexported,whicharecheaperinthecountryfromwhich,thaninthecountrytowhich,they
  aresent;andthatthosecommoditiesalonecanbeimported,whicharedearerinthecountryto
  which,thaninthecountryfromwhich,theyaresent。
  (3。xiii。3)Accordingtothisproposition,ifgoldischeaperinanyonecountry,asinEngland,
  for
  example,itwillbeexportedfromEngland。Again,ifgoldisdearerinEnglandthaninother
  countries,itwillbeimportedintoEngland。But,bytheveryforceoftheterms,itisimplied,that
  inanycountrywheregoldischeap,othercommoditiesaredear。Goldischeap,whenagreater
  quantityofitisrequiredtopurchasecommodities;andcommoditiesaredear,forthesame
  reason;namely,whenagreaterquantityofgoldisrequiredtopurchasethem。Whenthevalueof
  gold,therefore,inEngland,islow,goldwillbeexportedfromEngland,ontheprinciplethatall
  commoditieswhicharefreetoseekamarket,gofromtheplacewheretheyarecheaptothe
  placewheretheyaredear。Butas,inthefactthatgoldischeap,isimpliedthecorrelativeand
  inseparablefact,thatothercommodities,atthesametime,aredear,itfollows,that,whengoldis
  exported,lessofothercommoditiescanbeexported;thatnocommoditiescanbeexported,ifthe
  valueofgoldissolowastoraisethepriceofallofthemabovethepriceinothercountries;and
  thatadiminishedquantityalonecanbeexported,ifthevalueofgoldisonlyreducedsofarasto
  raisethepriceofsomeofthemabovethepriceinothercountries。
  (3。xiii。4)Itisevident,therefore,thatacountrywillexportcommodities,otherthanthe
  precious
  metals,onlywhenthevalueofthepreciousmetalsishigh。Itisequallyevident,thatshewill
  import,onlywhenthevalueofthepreciousmetalsislow。Theincrease,therefore,ofthe
  quantityofthepreciousmetals,whichdiminishesthevalueofthem,graduallydiminishesand
  tendstodestroythepowerofexportingothercommodities;thediminutionofthequantityofthe
  preciousmetalswhichincreasestheirvalue,increases,byasimilarprocess,themotiveto
  exportationofothercommodities,and,ofcourse,inastateoffreedom,thequantityexported。
  SectionXIV。TheValueofthePreciousMetal,orMediumof
  Exchange,WhichExportationIsNotDeterminestheSameinallCountries(3。xiv。1)Whenwespeakofthevalueofthepreciousmetal,wemeanthequantityofother
  things
  forwhichitwillexchange。
  (3。xiv。2)Butitiswellknownthatmoneyismorevaluable,thatis,goesfartherinthe
  purchase
  ofcommodities,notonlyinonecountrythananother,butinonepartthananotherofthesame
  country。
  (3。xiv。3)InsomeofthemoredistantplacesofWales,forexample,moneyismorevaluable
  than

  maybepurchasedwithasmallerquantityofmoney:andthisstateofthingsishabitual,money
  havingnotendencytogofromLondonwhereitsvalueislow,toincreaseitsquantityinWales
  whereitsvalueishigh。Thisphenomenonrequiresexplanation。
  (3。xiv。4)Thefactis,thatthewholeofsuchdifferenceasishabitual,andhasnotendencyto
  produceatransitofthemetals,resolvesitselfintocostofcarriage。Corn,butchers’meat,and
  othercommodities,whichareproducedinWales,arecheaperthaninLondon,becausethe
  supplyofLondoncomesfromadistance,andtheoriginalpriceisenhancedbycostofcarriage。
  ButastherearecertaincommoditieswhichthusarecheaperinWalesthaninLondon,sothere
  areotherswhicharecheaperinLondonthaninWales。Suchareallthecommoditieswhichare
  eithermanufacturedinLondon,orimportedintoLondonfromabroad。Justasthecornandother
  commodities,whichcomefromWalestoLondon,areenhancedbythecostofcarriage;sothose
  commoditieswhicharesentfromLondontoWales,aredearerinWalesthaninLondon,bythe
  wholeofthecostwhichisincurredintransportingthem。Thefact,therefore,is,thatinWales
  somecommoditiesarecheaper,andsomearedearer,thaninLondon;butthosewhichare
  cheaperarethearticlesofprincipalimportance;theyarethenecessariesoflife,thearticlesthe

  more,theyarethearticlesthemoney—valueofwhichdeterminesthemoney—valueoflabour;
  everythingwhichamanhasdoneforhim,therefore,isdonecheaperthanitisinLondon。And,
  lastly,thegrosscommodities,whicharetheproduceofWales,costmuchmoreforcarriage,in
  proportiontotheirvalue,thanthefinecommoditieswhicharereceivedfromLondon:thecostof
  thegrosscommoditiesinLondonismuchmoreraisedabovethepriceoftheminWales,than
  thepriceofthefinecommoditiesinWalesisraisedabovethepriceoftheminLondon。Thecost
  ofliving,therefore,isgreaterinLondonthaninWales,forthisreason,solely,becausepeoplein
  Londonpaymoreforcarriage。IfthevalueofthemetalinWalesroseeversolittleabovethat
  limit,aprofitequaltothatrisewouldimmediatelyoperateasamotiveforsendingittoWales。
  (3。xiv。5)Fromtwoplacesinthesamecountry,letustransfertheconsiderationtotwo
  different
  countries。Thecostoflivingishigher;inotherwords,thevalueofthepreciousmetalsislower
  inEngland,thaninPoland。Thedifferencehere,also,resolvesitselfwhollyintothecostof
  carriage。LetussupposethatEnglandreceivesaconsiderableportionofhersupplyofcornfrom
  Poland,andsendsherthewhole,orthegreaterpart,ofherfinemanufactures:corn,itisevident,
  willbedearerinEngland;butfinemanufactureswillbedearerinPoland。Forthesamereasons

  SectionXV。ModeinwhichthePreciousMetal,orMediumof
  Exchange,DistributesItselfAmongtheNationsoftheGlobe(3。xv。1)Inthecountryof’themines,whencegolddistributesitselftotherestoftheworld,
  gold
  isinrelativeplenty。Asanadditionisconstantlymakingtothequantityalreadypossessed,there
  isaconstanttendencyinthegoldofthatcountrytofallinrelativevalue;inotherwords,a

  sufficientlyhightoenablethemtobeimported,theywillcomeinfromthatcountry,beitwhatit
  may,fromwhich,primecostandcostofcarriagetakentogether,theycomethecheapest;and
  goldwillgooutinexchange。
  (3。xv。2)Bythisimportationofgoldintothatsecondcountry,itbecomesrelativelyplentiful
  there,andpricesrise。Somecommodity,orcommodities,becomethereatlastsodear,thatthey
  canbeimported,withprofit,fromanothercountry:commodities,asinthepreviousinstance,

  (3。xv。4)Suppose,whilefourquartersofcornand20yardsofclothrequiredthesame

  InEngland,accordingtothesupposition,thepriceoffourquartersofcornandthatof20yards

  andthereitwillbesoldforgold,becausetherecanbenocounterimportationofcorn,which,by

  (3。xv。8)Bytheimportation,inthismanner,ofEnglishclothintoPoland,goldgoesoutof
  Poland,andcomesintoEngland。Theconsequenceis,thatgoldbecomesmoreplentifulin
  England,lessplentifulinPoland。Fromthisfirstconsequence,asecondensues;thatprices
