1.Introduction Astrikingfeatureoftheearlypartofthe“GreatRecession”wasasuddencrashinthevalueof financialassets.Majorstock‐marketindices1intheUSandtheUKapproximatelyhalvedinvalue betweenpeaksinautumn/summer2007andlowsinMarch2009.ThedropinvalueofItaly’sFTSE‐ MIBwasevenmorepronouncedatmorethan60%betweenMay2007andMarch2009. Furthermore,alargepartofthechangesinassetvaluesoccurredduringthecentralmonthsof 2008,andsohouseholdsthatheldwealthinthestockmarketsufferedasudden,potentiallylarge andmostlyunanticipatedshocktothevalueoftheirfinancialwealth.Alongsidethesefallsinasset valuesthereweresubstantialfallsinhouseholds’consumptionexpenditures.Figure1.1shows thatforItalythepathofaggregateconsumptioncloselyshadowedthepathofthestock‐market index,witha3percentfallbetweenlate2007andmid2009that,ifanything,slightlylaggedthe fallinstockprices. Ouraimistousetheshocktoassetvaluesobservedin2008tomeasurethestrengthofthe responseofconsumptionspendingtothechangeinthevalueoffinancialwealth,fora representativesampleofItalianhouseholds.Giventhetimeperiodweareobservingwewillalso beabletocommentontheimportanceofthese“wealtheffects”,relativetootherfactors,in drivingthefallinhouseholds’consumptionduringtheearlypartoftheGreatRecessioninItaly. Amongthese“otherfactors”weconsidertheroleofchangesinhousingwealth.However,unlike theUSandUK,housevaluesinItalydidnotsufferlargefallsnearthebeginningoftheGreat Recession(AgenziadelTerritorio,2012),andsoouremphasisisontheeffectsoffinancialwealth.2 [Figure1.1abouthere] The2008shocktoassetvaluesisnotonlyusefulforusinprovidingempiricalvariationand thechancetoanalysetheimportanceofthisdriverofconsumptionintherecession,itisalso fundamentaltoourstrategyfordealingwithakeyendogeneityproblem.Allelseequal,a householdthatcuts(increases)itsconsumptionbymore,willmechanicallyaccumulatemore(less)  1TheDowJonesIndustrialAveragefortheU.S.,andtheFTSE“AllShare”fortheUK. 2Theabsenceofafallinhousevaluesalsounderpinsthelimitedeffectofwealthonconsumptioninresultsfromthe BankofItalyquarterlymodelforthe2006‐08period,reportedinRodanoandRondinelli(2014). 3  wealth.Unlessthisisproperlyaccountedforintheempiricalsetup,thiscouldleadtoa downwardsbiasin,orevenanegativeestimateof,wealtheffects.Weusetheideathatthe2008 shocktoassetvaluescanprovideasourceofvariationinwealththatisexogenoustohouseholds’ consumptionbehaviour.ApplyingamethodproposedbyBanksetal(2012),thisinsightisusedto buildaninstrumentalvariables(IV)estimator.Theprecisenatureoftheestimatorisdiscussedin section3. Ourstudyisrelatedtootherpapersthathaveaimedtoestimatetheimportanceofwealth effectsindrivingconsumptionbehaviourduringtheGreatRecession.Inaninfluentialstudyofthe U.S.,Mian,RaoandSufi(2013)estimateamarginalpropensitytoconsumeoutofhousingwealth of5–7percentfortheperiod2006‐09.Thisfindingisrobusttoinstrumentingusinggeographical constraintsonhousingsupply(whichshouldnotbecorrelatedwithotherdriversofconsumption), andtheauthorsalsoemphasizeevidencethatresponsestothewealthshockarestrongerwhere householdsarepoorerormore“levered”(indebted).3Giventhelackofafallinhousevalues mentionedabove,thewealthshockthatwelookatistofinancial,ratherthanreal,wealth.In anotherexcellentanalysisoftheUS,Christelis,GeorgarakosandJappelli(2015)havelookedat howlossesonfinancialwealth,lossesonrealwealth,andunemployment,affectedconsumption in2008‐09.Usingdatathataskhouseholdstoreportcapitallossesondifferentassetstheyfinda marginalpropensitytoconsumeoutoffinancialwealthofaround3.3percent(andsmallereffects forlossesonhousing).Inlinewitheconomictheory,theyalsofindevidencethatthosewho expectedthestock‐marketshocktobepermanentadjustedtheirconsumptionmorestronglythan thosewhoexpectedtheshocktobetransitory.Asmentionedabove,themethodologyofour studydrawsontheEnglandbasedanalysisofBanksetal(2012).Thoseauthorshaveless comprehensivedataonspendingthanwedoandasampleofagentsaged50+.Theyfindonly modesteffectsonhouseholdspendingofwealthshocksduringthecrisis,butarealsoabletofocus onwealtheffectsonotheroutcomes(includingexpectationaloutcomes)thatwedonotobserve. Toourknowledgeourpaperisthefirstattempttolookatthedriversofchangeinconsumption, includingwealtheffects,duringtheGreatRecessioninItaly.OurdatacomefromtheBankof Italy’sSurveyonHouseholdIncomeandWealth(SHIW),whichprovidesrichdataonhouseholds’ assetholdings(valuesandownership),consumptionoutcomes,anddemographicandeconomic  3IndeedthisworkispartofabroaderprogrammeofresearchinwhichMianandSufiarguefortheimportanceof “leveredlosses”fordrivingthelargeconsumptioncontractionearlyintheGreatRecession;theirargumentsand findingsarebroughttogetherinMianandSufi(2014). 4  characteristics.ThedataaredesignedtoberepresentativeoftheItalianresidentpopulationand alsohaveapanelcomponent,andthiscombinationofcharacteristicsisuniqueforItalyand impressiveevenbyinternationalstandards.ThusouranalysisoftheItalianexperienceisof broaderinterestforunderstandingtheimportanceofwealtheffectsandtheevolutionof consumptioninEuropeintheGreatRecession.4 AnalysesoftherelationshipbetweenwealtheffectsandconsumptionduringtheGreat Recessionfitinanestablishedliteratureregardingmeasuringwealtheffectsonconsumption. Therehasbeenmuchrecentemphasisonhowpropensitiestoconsumefromrealwealthdiffer frompropensitiestoconsumefromfinancialwealth5;animpressiverecentsurveyoftimeseries andmicro‐econometricevidenceonwealtheffectsisprovidedbyPaiella(2009),itselfbuildingon theequallyexcellentPoterba(2000).Thestudiesmostrelatedtothepresentpaperarethosethat provideevidenceforItaly.Paiella(2007)usespooledcross‐sectionsofdatatoestimatelong‐run marginalpropensitiestoconsumefromdifferentformsofwealthwhileCalcagno,Forneroand Rossi(2009)focusontheeffectsofrealestatewealth.Guiso,PaiellaandVisco(2005)iscloserto ourstudyinthat,inlinewithouranalysisbasedonshocks,theyaimtoestimatetheeffectsof capitalgainsaswellaslongrunrelationshipsbetweenwealthandconsumption;theyfindthaton averagea1eurogaininhousingwealthincreasesannualconsumptionbyaround2cents,while capitalgainsonfinancialassetsmayevenleadtoreductionsinconsumption.Ourkeycontribution tothisliteratureliesinourexploitationoftheassetpriceshockatthestartoftheGreatRecession asanewsourceofplausiblyexogenousvariationinassetvaluesinordertoestimatehow

4ThestudiescitedinthisparagraphthemselvesfitintoabroaderliteratureonconsumptionduringtheGreat Recession.Petev,PistaferriandSaportaEksten(2011)andDeNardi,FrenchandBenson(2012)fortheUS,and Crossley,LowandO’Dea(2013)fortheUK,providedescriptiveanalysesthatpointtounusualfeaturessuchasthe durationofthecontractioninconsumption,andthebroadrangeofconsumptioncategoriesthathavebeenaffected. ForItaly,Rondinelli,BassannettiandScoccianti(2014)showthatnationalaccountsdataandhouseholdleveldata matchquitewellduringtherecentperiodandthattherehavebeensomedifferencesinchangesinexpenditure sharesacrossagegroupsbutwithageneralshiftawayfrom“leisure”expenditures.RodanoandRondinelli(2014) comparedifferentrecentrecessions.ResultsfromtheBankofItaly’squarterlymodeldonotindicateastrongrolefor wealthinaggregateconsumptionduringtheperiod2006‐08.However,themeasureofwealthinthemodelcombines realandfinancialwealthanddoesnotshowacontractionduringtherelevantperiod;whentheauthorsdescribe microdatatheydofindthefallsinthevalueoffinancialassetsthatareourfocus. 5SeeSlacalek(2009)andCase,QuigleyandShiller(2005). 5  Preciselystated,ourresearchgoalistoestimatethemarginalpropensitytoconsume(mpc6) outoftheshocktofinancialwealththatoccurredatthestartoftheGreatRecession.Apreviewof keyresultsisasfollows.Aoneeurofallinfinancial(orriskyfinancial)wealthresultedin householdscuttingannualtotalconsumptionspendingbybetween8.5and9cents,andslightly morethan5.5centsofthiscutwasinspendingonnon‐durablegoodsandservices.Wefind effectsofaround1.5centsforfoodspending,andinsignificantresults(thoughwiththeexpected positivecoefficients)forexpenditureondurables.Wealsofindthataoneeurochangeinhousing wealthresultsintotalandnondurableconsumptionspendingmovinginthesamedirectionby aroundbetween0.2and0.3cents,butwedonotfindsignificanteffectsonfoodordurables expenditures.Wealsofindevidencethatourestimatesofwealtheffectswouldbelargerifwe excludetheoldestandyoungesthouseholdsfromourdata,andevidencethatindicatesstronger consumptionresponsestothewealthshockamonghouseholdswhoalsobecamepessimistic abouthowtheyexpectedthestockmarkettoperformandamonghouseholdswithsome mortgagedebt.Finally,counterfactualsimulationsindicatethatfinancialwealtheffectswerean importantdriver(relativetootherfactors)ofconsumptionfallsintheearlypartoftheGreat RecessioninItaly,accountingfor17to22percentofcutsinspendinginoursample.Thusour resultsindicatethatwealtheffectsonconsumptioncanbeimportantforhouseholds’welfareand foraggregateconsumptionandeconomicperformance. Thepaperisorganisedasfollows.Section2introducesthedatasetthatweuseandprovides somedatadescriptivesthatfurthermotivateouranalysis.Section3thenexplainsourresearch method,describingbothourIVestimatorandakeyvariablethatmustbeconstructedinorderto implementthisestimator.Section4thenpresentsourmainresultsonwealtheffects.Wefirst presentaveragewealtheffectsforbroadmeasuresofconsumption,thenresultsforfinerspending categories.Wethenputthesizeofourresultsincontext,includingthroughcounterfactual simulations,andsubsequentlylookatheterogeneityinwealtheffectsbetweengroupsofthe population.Finally,section5concludes.  

Inthissectionwedescribethestructureofthedatasetthatweuse,andtheconsumptionand wealthvariablesthatareessentialtoouranalysis.Descriptionofthesekeyvariablesalsohelpsto motivateouranalysisofwealtheffects. 2.1TheSHIWDataset TheSurveyonHouseholdIncomeandWealth(SHIW)isarepresentativesampleoftheItalian residentpopulation.Samplingisintwostages,firstmunicipalitiesandthenhouseholds.From 1987onwardthesurveyisconductedeveryotheryear(withtheexceptionofatwo‐yeargap between1995and1998)andcoversabout24,000individualsand8,000householdsinaround300 municipalities.Ahouseholdisdefinedasagroupofindividualsrelatedbyblood,marriageor adoptionandsharingthesamedwelling.About50%ofhouseholdsinagivenyearareinterviewed atleastonceinsubsequentyears(panelcomponent). Thesurveyrecordsarichsetofhouseholdandpersoncharacteristicsaswellasinformation onincomesandsavings,andonhouseholdexpenditureandwealth.Wealthdataisrich,containing bothparticipationandvalueforarangeoffinancialassets,housingwealth,andbusinesses.For thepurposeofouranalysis,weusedatafortheyears2004‐2010.Inthiswayweareableto observechangesinwealthandconsumptionduringthe“GreatRecession”(2006–08and2008– 10)andalsotoconstructourinstrumentalvariableusinginformationonhouseholdportfolios fromthe2004and2006surveys. InthenexttwosubsectionswedescribetheSHIWvariablesthatarethemostimportantfor ouranalysis,thoseregardingconsumptionandassetholding. 2.2SHIWconsumptionvariables TheSHIWdatasetrecordsconsumptionspendingonfourdifferentcategoriesofproducts.Total consumptionisthesumoftwoothercategories,namelydurable(meansoftransport,furniture, householdappliances,etc.)andnon‐durableexpenditures.Foodconsumptionisasubclasson non‐durablespendingandincludesmealsathomeoreatenout.Inouranalyseswealways measureexpendituresannuallyandinrealterms(2010euros,basedontheHouseholdIndexof ConsumerPricesprovidedbyIstat). Descriptivestatisticsonconsumptioninoursampleareshownintable2.1.Totalconsumption decreasesbetween2004and2010,but,onaverage,thedropisstatisticallysignificantat1%only 7  between2006and2008.Thisdropislargelydrivenbynon‐durableexpenditurethatsignificantly decreasesbymorethan600eurosonaveragebetween2006and2008,withalmost400eurosof thischangecomingfromfoodconsumption.Durableconsumptiondisplaysaslightlydifferent pattern.Itsignificantlydecreasesonlyin2010,when,onaverage,durablegoodsexpenditure decreasesby300euros. [Table2.1abouthere] 2.3SHIWfinancialwealthvariables TheSHIWdatasetcollectsdetailedinformationonhouseholdportfolios.Respondentsareasked whethertheyholdeachofmanytypesofassetand,ifso,abouttheamountofwealththeyholdin eachasset.Assetsaregroupedinbroadcategories:cash(bankaccountsandsavingcertificates); Italiangovernmentbonds(withdifferentdurations);domesticbondsandinvestmentfunds;Italian shares;foreignbondsandshares;otherminorcategories.Withineachofthesebroadcategories individualsareaskedaboutadetailedsetofassets.SHIWalsoprovidesinformationonhousehold wealthinseveraltypesofmutualfunds,andthesefundscanbecategorisedaccordingtowhether ornot(andtheextenttowhich)theyexposetheholdertostock‐marketrisk. Ifsurveyrespondentsreportthattheyholdanasset,theyarethenaskedabouthowmuch wealththeyheldinthatassetatthe31stofDecemberintheyearafterwhichthesurveywaveis named(i.e.December31st2008forthe“2008SHIW”).7Respondentsarefirstaskedtoindicatein towhichofseveralbandsofvaluetheirassetfellandthentoreportapointamountforthisvalue. Failuretoreportapointamountresultsinthehouseholdbeingaskedwhetherthevalueoftheir

18TheseownershipratesarecalculatedbytheauthorsusingtheSHIWdata(withsampleasusedinTableB1).Note thattheownershipratescannotbeinferredfromthenumbersinTable3.1becausethesample“withriskyassets”in

savinginhousingandchangesinconsumption.Onthebasisoftheseargumentsweinterpretthe coefficientonchangesinhousevaluetobethempcoutofshockstohousingwealth. Theremainingregressorsinallthereportedregressionsincludechangesin:unemployment status;retirementstatus;and,inthenumberofpeopleandearnerslivinginthehousehold.The variablessofardiscussedareallinfirstdifferences.Thereportedresultsalsoalwaysallowforthe possibilitythatthechangeinconsumptionisrelatedtothecharacteristicsofhomeownership,

Forinterpretationofthemainwealthcoefficients,itiseasiesttoconsideranexample.The coefficientonthecalculatedchangeinriskyfinancialwealthinIVregressionreportedincolumn3 ofthetoppanelofTable4.1(thisistheregressionforthechangeintotalconsumptionandthat includesthechangeinincomeasaregressor)is0.088.Sincecalculatedchangesinwealthare measuredinreal(2010)euros,andconsumptionismeasuredineurosperyear,thispointestimate indicatesthatifwealthincreases(falls)byoneeuro,annualconsumptionincreases(falls)by8.8 cents.Inotherwords,thecoefficientindicatesanmpcoutofthewealthshockof8.8percent. Othercoefficientsonwealthvariablescanbeinterpretedanalogously. Withthisinterpretationinmind,wecansummariseourmainIVresultsfortheeffectsofthe shocktofinancialwealthonconsumption,asfollows.Wereportresultsfromregressionswiththe controlforthechangeinlabourincome,andinbracketstheresultswithoutthiscontrol.Fortotal consumption(Table4.1),thempcis8.8(8.6)percentoftheshocktoriskyfinancialwealth,and10 (9.9)percentoutoftotalfinancialwealth.Fornon‐durableconsumption(Table4.2)theestimates are5.7(5.5)percentoutoftheshocktoriskyfinancialwealth,and6.2(6.1)outoftotalfinancial wealth.Itisageneralpatterninourresultsthatcontrollingforthechangeinlabourincomehas almostnoimpactontheestimatesofourmaincoefficientsofinterest.Asapointofcomparison, theestimatedmpcforchangesinfinancialwealthareconsiderablylargerthantheresultsthatwe getforthepropensitytoconsumeoutofachangeinhousingwealth,whichisrobustlyestimated tobebetween0.3percentand0.1percent. ComparingtheseIVresultstoOLSestimates(columns1and2inTables4.1and4.2),wesee thattheOLSresultsarealwayssubstantiallysmallerthantheIVestimates.Thisisinlinewiththe argumentsoftheprevioussectionthattherearegoodreasons(themechanicalrelationship betweenchangesinconsumptionandinwealththroughthebudgetconstraint,andattenuation biasduetomeasurementerror)toexpectOLSestimationtounderestimatethiscoefficient.20

20Wedonotreportthe“reducedform”thatrelatesthechangeinconsumptiontotheexcludedinstrument(andthe otherregressors).Giventhatwehaveoneendogenousvariableandexactidentification,thecoefficientonthewealth variableinthisreducedformcanbeinferredastheproductofthecoefficientsontherespectivewealthvariablesin 17  Focussing(fromhereforward)onourpreferredIVestimates,wenoticethatthepoint estimatesforthempcareveryslightlysmallerbutmorepreciselyestimatedwhenthekey independentvariableisthechangeinriskyfinancialwealth(toppanelofTables4.1or4.2), comparedtowhenitisthechangeintotalfinancialwealth.Forexample,ifwetakethecasesfor totalconsumptionandwiththecontrolforthechangeinlabourincome(column3oftheTable 4.1),theestimatedcoefficientis:0.088(significantatthe10%level)whentheregressorrelatesto riskywealth;and,0.1(notsignificantatconventionallevels)whentheregressoristhechangein totalfinancialwealth.Theequivalentcoefficientsfornon‐durableconsumptionrespectivelyare 0.057(significantatthe5%level),and0.062(significantatthe10%level).Thegreaterprecision whentheregressoristhechangeinriskywealthispartlyduetothefactthatwehavegreater precision(asmallerstandarderrorontheinstrument)inthefirststageforthecaseusingrisky wealth,whichindicatesthatinstrumentingaddslessnoiseinthiscase.Thegreaterprecision,and largersize,oftheestimatedcoefficientontheexcludedvariableinthecasewithriskywealth againindicate(asnotedinsubsection3.2)thatthereisastrongerrelationshipbetweenasset pricesandthevalueofriskywealththanbetweenassetpricesandthevalueofallfinancialwealth, perhapsbecauseportfolioreshufflingandtheaccumulationofsafeassetsweakentherelationship tototalwealth.TheF‐statisticontheexcludedinstrumentalsoindicatesthatourIVstrategyis moreeffectivewhentheregressoristhechangeinriskywealth:inthatcasewedonotneedto worryaboutaweakinstrumentproblem.Fullfirst‐stageresultsarereportedinAppendixTables B3(riskyfinancialwealth)andB4(totalfinancialwealth). Asalreadynoted,thewealtheffectcoefficientsarerobusttocontrollingforthechangein labourincome.Ourresultsarealsorobusttoaseriesofothermodificationstoourspecifications. Forexample,whileourdataareforchangesinwealthandconsumptionbetween2006and2008, and2008and2010,mostofthevariationthatourestimatorexploitsisrelatedtotheassetprice shockthatoccurredbetweenthe2006and2008wavesofdata.Estimationbasedonlyon differencesforthe2006‐2008periodleftourresultsalmostunchangedrelativetothosereported. Anotherrobustnesscheckinvolvedslightlychangingthewayinwhichweconductedour  thefirstandsecondstagesoftheIVregression(thisisthereverseofindirectleastsquares).Giventhatthecoefficients inthefirststages(reportedinAppendixTablesB3andB4)are0.672(forthechangeinriskywealth),andjustbelow 0.6(forthechangeintotalfinancialwealth),thereducedformestimateswouldbesmallerthanourIVestimates. However,therearereasonstosupposethatthereducedformwouldunderstatetherelationshipofinterest.In particular:thechangeincalculatedwealthislikelytooverstatethetrueshocktowealth(andthusleadtoan understatementofeffectsmeasuredpereuroofchangeinwealth)ifhouseholdscanoffsetsomeoftheassetprice shockthroughtheirportfoliochoices;and,thereducedformwouldbeaffectedbyattenuationbiasifthereis measurementerror.TheseissueswerediscussedinmoredetailinBottazzi,TrucchiandWakefield(2013). 18  instrumentalvariablesanalysis.Asnotedinsection3,thevariationexploitedbyourinstrumentis heterogeneitybetweenhouseholdsintermsofthelevelofwealthheldindifferentassets,and differencesinreturnsbetweenassets.Wehavetriedincludingthe(twice‐lagged)levelofwealthin differentassetsandtheinteractionofthiswiththestock‐marketindex(theFTSEMIB)intheplace oftheconstructedchangeincalculatedwealthastheexcludedvariablesinthefirststageofourIV analysis.Againtheresultsarealmostunchangedrelativetothosewereport(infactthechange sometimesimprovesthesignificanceofourresults).Anothermodificationthatmakespractically nodifferencetoourestimatesistodropregressorsfor(lagged)retirementstatus,sectorof employment,andhomeownership;intheresultswereport,theselevelvariablesareincluded alongsidevariablesmeasuringthechangeinretirementstatus,housingwealthandemployment. Afinalrobustnesscheckistoruntheregressionswithdeltariskywealthasthekeyregressor,only onthesampleofthosewhohaveriskywealth.21Sincethecoefficientonthekeywealthvariable measuresthechangeinconsumptionperunitofchangeinwealth,includinghouseholdswithout riskywealth(aswedointhereportedresults)shouldnotaffectourestimatedcoefficientsand indeeddroppingthesehouseholds(andshiftingtoamuchsmallersample)doesnotsubstantially affectourpointestimates.Fullresultsfromtherobustnesschecksdescribedinthisparagraphare

Tosummarise,theresultsdiscussedinthissectiongivetheaverageeffectofthewealthshock ontheconsumptionofhouseholdsinoursample.Ourfavouredestimatesindicatethataeuroloss

Thepointestimatesincolumns(c1)and(c2)ofthetableindicatethatdurablesexpenditures wereaffectedby,onaverage,3.1centsperyearforaeurochangeinriskywealth.Sincetotal consumptionspendingisthesumofspendingondurablesandspendingonnon‐durables,the changeintotalspendingpereurochangeinwealthshouldbethesumofthechangesinspending

aroundorjustabove5.5percentfornon‐durableconsumption.TheseeffectsdifferfromtheItaly basedfindingofGuiso,PaiellaandVisco(2005)thatconsumptionmayevenfallinresponseto capitalgainsonfinancialassets.Onecouldonlyspeculateastowhetherthisdifferencecomes fromdifferencesinsampleperiodordifferencesinthemethodandvariationusedtocapture effects.ItisslightlydifficulttomakeadirectcomparisonofourresultstothoseofBanksetal. (2012),thepaperthatisclosesttooursintermsofmethodology,sincetheydonotobservesuch comprehensivemeasuresofconsumptionspendingaswedoandtheirsampleisforarestricted (older)agerange.However,ifwetrytoextrapolateaneffectontotalconsumptionfromtheir resultsitwouldseemthatthiswouldbeweakerthanourfindings.Ourfindingsforspendingon

foodarealsostrongerthanthesumoftheirresultsforfoodinandfoodout.Comparedtoother, USbased,resultsforwealtheffectsintheGreatRecession,ourmpcoutoffinancialwealthis somewhatlargerthanthe3.3percentfoundbyChristelis,Georgarakos,andJappelli(2015),but onlyslightlylargerthanthempcoutofhousingwealthestimatedbyMian,RaoandSufi(2013). Moregenerallyourfindingsonmpcoutofshockstofinancialwealthdonotseemoutoflinewith findingsintheliterature(seeforexamplethecollectionofmicro‐databasedresultsinTable3of Paiella(2009)),althoughanestimateof0.088or0.086fortotalconsumptionisperhapsatthetop endoftherange. Ourfindingsonmpcfromchangesinhousingwealthare(fortotalandnon‐durable consumption)robustlyintherange0.001–0.004.ThisisinlinewiththefindingsofGuiso,Paiella andVisco(2005).Thusourfindingsseemtoconfirmthattheaveragemarginalpropensityof Italianhouseholdstoconsumefromchangesintheirhousingwealthisreasonablyinlinewith (perhapsatthelowerendof)therangeofinternationalestimatesofthisparameter. Anotherwayofthinkingaboutthesizeofourestimatedmpcistoconsiderwhatthesempc implyforhowmuchsmallerobservedfallsinconsumptionwouldhavebeeninourdataifthe valueoffinancialassetshadnotfallenin2008.Wecanaddressthisissuebyperforming counterfactualsimulationsbasedonourregression.Thatistosay,wefirstusetheregressionto predicttheaveragechangeinconsumptioninoursample.Wecanthen(counterfactually)setthe changeinwealthtozeroforallindividualsinoursampleandmakeanewprediction.24Comparing thetwopredictionswillgiveameasureofhowmuchoftheaveragefallinconsumptionisbeing drivenbywealtheffects.Wecanalsocomparethisinfluenceofwealtheffectstotheimpactof otherfactorsbyusingasimilartechniqueto“switchoff”theinfluenceof(say)changesinhousing wealth,unemploymentstatus,thenumberofearnersinthehousehold,orinlabourincome. [Table4.4abouthere] Table4.4displaystheresultsofthiskindofcounterfactualexercisebasedontheIV regressionforthechangeintotalconsumptiononthechangeinriskywealth(andincludingthe

upisto“manually”computethetwostepsoftheIV.Thatis,ratherthanusingabuiltinpackageintostatistical

constructthe“predictedwealth”variablethatbecomesaninputintothesecondstagewhichiscomputedbya seconduseoftheregressioncommand.Sincethisprocedureinvolvesexplicitlyobtainingthe“predictedwealth”

changeinlabourincome),thatisreportedinthetoppanelandthirdcolumnofTable4.1.We reportresultsforthecounterfactualexercisecomputedacrossallhouseholdsinoursample(first columnofTable4.4),andonlyforthe(approximately)halfofthesamplewhosechangein consumptionismeasuredfortheperiodofparticularlylargeassetpriceshocks(2006–08,second columnofTable4.4). Inourfullsampletheaveragetwo‐yearfallinannualconsumptionis515euros.Thisfall amountstoalmost3%ofaverageconsumptionspendinginoursample,25afigurewhichis reasonablyinlinewiththefallinaggregateconsumptioninItalyoverthesameperiod(seeFigure 1.1).Sinceweareusingleast‐squaresregression,the515eurofallismatchedbytheaverage predictionofconsumptionchangesbasedonourregression.Ifwerepeatthepredictionexercise butwiththe“predictedwealth”variablefromthefirststageoftheIVsettozeroforthosewho haveriskywealth,wefindtheaveragefallinconsumptionisreducedto425euros.Thus,wealth effectsareexplainingaround90outofthe515euroaveragefall,orapproximately17%ofthefall inconsumptiononaverage.Incontrast,changesinhousingwealthonlycapturearound3%ofthe averagefallinconsumption.Thepartofthechangeinconsumptionexplainedbywealtheffectsis alsoveryslightlylargerthantheproportionscomingfromeitherchangesinlabourincome,or fromthejointimpactofchangesinthenumberofearnersandinunemploymentstatus. Itmayseemsurprisingthatthechangeinthevalueofriskywealthissopowerful,relativeto otherfactors,whenonlyaround14%ofoursampleheldriskyfinancialwealthbeforetheasset priceshock(in2004or2006).However,theshocktowealthwaslarge.Theresultsfromourfirst stageindicatethattheassetpriceshockledtoanaveragefallinthevalueorriskywealthof7130 eurosamonghouseholdswithsomeriskywealthbeforethecrisis,andcombiningthiswithour mpcestimategivesanaveragecutinconsumptionduetothewealthshockof627eurosperyear amongthesehouseholds.Averagingthesizeofthecutacrossallhouseholds(withandwithout

around4.5percent,whichisagainquitewellinlinewithaggregatedata).26Inthiscasewesee thatthechangesinfinancialwealtharedrivingmoreofthefallinconsumption(around22%ofit)

isnotasstrongastheeffectoftheshocktowealth.  4.4HeterogeneityinWealthEffects Thewealtheffectsconsideredsofarareaverageeffectsinoursample.Theconceptualframework underpinningourresearchsuggeststhattheremightwellbeheterogeneityinwealtheffects.We considerheterogeneitybyage,andwhetherthestrengthofwealtheffectsisrelatedtobecoming pessimisticaboutthestockmarketorbeingexposedtomortgagedebt. Heterogeneitybyage Thesimplelife‐cyclemodelthatweappealedtoinsection3,predictsthatagentsshouldconsume aproportionoftheirwealthineachperiod,andsoshouldsmoothoutshockstowealthby spreadingthechangesinspendingthattheseshocksnecessitate,acrosstheremainingperiodsof theirlives.Giventhat,allelseequal,olderindividualshaveashorterhorizonoverwhichtheycan distributechangesinconsumptionspending,themodelsuggeststhatolderindividualsshould respondmorestronglytothewealthshocks.27Aricherversionofthemodelmakestheprediction lessclearcut.Ifhouseholdsformlinksinongoingfamilialdynasties,thenthemodelmay effectivelyhaveaninfinitehorizonthuspotentiallydecouplingthelinkbetweenageandthelikely strengthofresponsestowealthshocks.Alternatively,creditconstraintsmaymeanthatthe consumptionofyoungerhouseholdsiscloselytiedtocurrentresources,andsothesehouseholds maybeveryresponsivetoshocks.Giventheambiguity,itisanempiricalquestiontotryto establishwhetherandhowwealtheffectsvarywithage. Withourinstrumentalvariablesstrategy,preciseidentificationisquitedemanding.To mitigateproblemswithsamplesizeandpotentiallyweakinstruments,ourapproachto investigatingheterogeneitybyageistore‐estimateourmainmodelonthefollowingsubsamples: asampleexcludinghouseholdsheadedbysomeoneaged70orabove;asampleexcludingthose agedlessthan50;and,asampleexcludingboththe“young”(under50s)andthe“old”(70plus). Eachrestrictiondropsaroundaquarterofthehouseholdsfromourmainsample,sothesample withneithertheoldnortheyoungisslightlylessthanhalfthesizeofthesampleusedinTables4.1
