II.LiteratureReview

Jobamenitiesarechallengingtoquantifyandvaryinpreferencedependingonindividualattributes.Despitethesechallenges,therehavebeeneffortstoconvertjobamenitiesintomonetaryvalues(willingnesstopay)andcalculatecompensatingdifferentialstoaccountfordifferencesinspecificjobamenitiesunderidenticalconditionsofworkers'individualattributesorjobconditions.However,unobservablecharacteristicsinemploymentdatahavemadeitdifficulttomeasurethevalueofjobamenitiesaccurately.

Recentstudieshavesoughttoestimatethemonetaryvalueofjobamenitiesbycontrollingforjobconditionsthroughstatedpreferencetechniques.Notably,Maestasetal.(2023)computedthemonetaryvalueofjobamenitiesusingthestatedpreferencemethodandsubsequentlyanalyzedchangesinincomeinequalityintheUnitedStates.Theirfindingsalsorevealedthatpreferencesforeachjobamenitydifferbygenderandage.Similarly,MasandPallais(2017)usedstatedpreferencetechniquestodemonstrateworkers'willingnesstobargainforflexibleworkarrangementsinexchangeforwagecuts.1

Maestasetal.(2023),Acemogluetal.(2022)identifiedage-friendlyjobswithrobustjobamenitiespreferredbytheelderly,showingthatjobsintheUnitedStatesarebecomingincreasinglyage-friendly.Meanwhile,Baggaetal.(2023)demonstratedthatthepreferenceforjobamenities,suchasremotework,increasedsignificantlyafterthepandemicandthatthischangeinpreferencewasthemostcrucialfactorinlaborreallocationintheUnitedStates.AdditionalstudiesincludeNeumarkandSong(2012),whofoundthatphysicallydemandingjobsleadtoearlierretirements,andSaragih(2011),whoprovedthatjobautonomypositivelyaffectsworkers'performanceandsatisfaction.Lastly,Barronetal.(1999)showedthatpersonaldevelopmentopportunitiesintheworkplaceleadtohigherfutureincome.

ThispapercalculatesthejobamenityindexbasedonthemethodologyofAcemogluetal.(2022)andMuhlbach(2022)2.First,eightjobamenities3,suchasflexiblework,remotework,physicaldemands,paceofwork,autonomy,independence,personaldevelopmentpotential,andcareersatisfaction,areselectedbasedonMaestasetal.(2023)andAcemogluetal.(2022)(see<Table1>).Next,theattributesofjobsofferingahighstandardineachtypeofjob
