riskydrivers.OverconfidenceimpliesiiTationalratherthanrationalrisk-takingbehavior;

however,aspointedoutbyCarr-HillandStern(1979),theeconomicandbehavioralapproaches

tocrimeshouldbeseenascomplementaryratherthanconflicting.

Auditors,likeotherindividuals,possessdifferentpersonalcharacteristics,including

differentpreferencesregardingriskandtendencytocriminalbehavior.Severalexperimental

studieshaveexaminedthediversityinauditors'personalcharacteristicsrelatedtotheir

propensitytotakerisk,andhowthesecharacteristicsaffecttheauditworkunderdifferent

circumstances.Forexample,Schatzbcrgctal.(2005)findapositivelinkbetweenauditors'

Priorstudieshavealsoexaminedbehavioralbiases,suchasoverconfidence,among

auditors.Messierelal.(2008)findthatauditpartnersexhibitsignificantoverconfidenceinthe

overconfidenceincreaseswiththeknowledgegapbetweensupervisorsandsubordinates.

Whilemanystudieshavelookedatauditfirmleveldata,recentstudieshavefocusedmore

onoffice-levelanalysis.Forexample,ReynoldsandFrancis(2000)examineclientaccrualsand

auditorgoingconcernreportsattheofficelevelofanalysisandfindevidencesuggestingthat

2.2.TestablePredictions

Priorexperimentalstudieshaveshownthatauditorsevaluateclient-relatedriskstoavoid

lossesfromauditengagement.Forinstance,Johnstone(2000)arguesthatauditpartnersevaluate

client-relatedrisks,andusethoseevaluationstodeterminewhethertheauditfirmwillsuflera

lossontheauditengagementduetopotentiallitigation.Otherstudiesshowthatauditorsassess

clicnt-spccificriskbyusingtheclient'sfinancialcondition(PrattandSticc,1994),levelof

corporategovernance(CohenandHanno,2000),andqualityoffinancialreporting(Cohenand

Trompeter,1998).

Theauditfirmlevelresultsonwhetherauditorsvarybytheirtolerancetowardsclientrisk

aresomewhatcontradictory.JonesandRaghunandan(1998)arguethatlargeauditfirmsavoid

7

riskbecausetheyhavemoretolosefromauditfailure.Bycontrast,FrancisandKrishnan(2002)

arguethatlargeauditfirmsaccepthigh-riskclientsbecausetheycandiversifythatriskacross

theirclientportfolio.Therefore,thequestionofhowauditpartners'personalriskpreferences

affectclientportfoliodecisionsisstillanopenone.

Wearguethatauditpartnerswithpriorcriminalconvictionsaremorewillingtoaccept

riskierclientsthanauditorswithoutcriminalconvictions.Consequently,weexpectclientsof

auditpartnerswithcriminalconvictionstobecharacterizedbyhigherfinancialrisk,weaker

governanceandmoreaggressivefinancialreporting,thanclientsofauditpartnerswithout

criminalconvictions.

SimunicandStein(1990)focusonfinancialriskandfindthatauditor'sriskincreaseswith

thedegreeofclients'financialrisk.Hence,anauditpartnerwithapriorcriminalconviction,

whoismorewillingtoengageinriskierauditengagement,ismorelikelytohaveclientswith

greaterfinancialrisk.Thisleadstothefollowingprediction:

Prediction1:Clientsofcriminallyconvictedauditpartnershaveagreaterfinancialriskthan

thoseofnon-convictedauditpartners.

Weakercorporategovernanceincreasestheauditriskbecauseweakergovernanceis

associatedwithhigherlikelihoodoffraud,misappropriaticnsoffunds,andopportunistic

accountingdecisions,whichcouldalsoleadtohigherlitigationrisk.Anauditpartnerfacing

clientswithweakergovernanceisrequiredtotakethatintoaccountinplanningandexecuting

auditors'decisiontoaccepttheclient.Duetotheirgreatertoleranceofrisk,auditpartnerswith

8

criminalconvictionsaremorelikelytotolerateweakergovernanceoftheirclientfirms.This

leadstothesecondprediction:

Prediction2:Clientsofauditpartnerswithpriorcriminalconvictionshaveweakergovernance

thanclientsofauditpartnerswithoutcriminalconvictions.

Thelevelofconditionalaccountingconservatism,oftenmeasuredastheasymmetric

TwotypesofauditorsinSwedenareallowedtoauditlistedfirms:approvedauditorsand

authorizedauditors.Tobecomeanapprovedauditor,thecandidatemustobtainabachelor's

becomeanauthorizedauditor,theapprovedauditormustobtainamaster'sdegree,complete

auditfirmsformteamsofauditorsledbyauditpartners.Theseteamleadersareresponsiblefor

keyclient-specificdecisions,includingthescopeandpricingoftheauditengagement.

Therefore,leadingauditors'personalattributes,asmeasuredbytheircriminalconvictions,are

likelytoplayanimportantroleinaudit-relateddecisions.

thetaxauthorities,thattheyarenotbankruptandthattheydonothavelegalguardianship.However,

criminalrecordchecksarelimitedtoeconomic-relatedcrimesandcrimesrelatedtotheauditprofession.

AuditingstandardsissuedinSwedenarebasedonInternationalAuditingStandards,but

someadditionsandchangeshavebeenmadetocertainstandardstomakethemconsistentwith

Swedishlaw.Tomaintainauditorindependence,SwedishandEuropeanlawsrequirethat

auditorshaveneitherafinancialinterestnoranyclosepersonalrelationshipwiththeclient.
