    Abstract$

    This' research' explores' the' effect' of' innovation' on' income' inequality' in' Canadian'

    metropolitan'areas'from'1991'to'2011.'The'analysis'has'been'done'through'regression'

    analyses'on'the'income'and'employment'data'obtained'from'long'form'Canadian'census'

    and'National'Household'Survey'microRdata.'The'results'show'that'the'positive'correlation'

    between' innovation'and' income' inequality' in'Canadian'cityRregions'grew' from'2001' to'

    2011T'however,'there'was'no'correlation'between'them'in'1990s.'Among'three'parameters'

    that' were' used' as' a' measure' of' innovation' in' this' research' (ratio' of' employment' in'

    KnowledgeRIntensive' Business' Services' (KIBS),' highRtech' occupations' and' highRtech'

    industries),' the' ratio'of' employment' in'KIBS'has' the'most' significant' effect.'Moreover,'

    cities' with' a' high' rate' of' KIBS' activities' have' a' higher' level' of' withinRindustry' income'

    inequality,'that'is,'between'highRtech'occupations'and'other'employees'within'the'same'

    industry.'

    Chapter$1.$ Introduction$and$Thesis$Outline$

    Innovation' is' an' important' factor' in' economic' growth' during' the' last' century'

    (Glaeser'1991T'Porter'2000).'It'provides'the'opportunity'for'its'adopters'to'create'new'jobs,'

    introduces'new'industry'sectors'and'develops'new'products.'Some'researchers'believe'

    that'urban'environments'attract'firms'and'people'because'of'knowledge'spillovers,'and'at'

    the' same' time' attraction' and' agglomeration' of' firms' and' people' in' cities' increase' the'

    knowledge' spillovers' and' innovation' (Marshall' 1890T' Jaocbs' 1970T' Saxenian' 1996).'

    Therefore,' local' governments' try' to' stimulate' innovation' through' attracting' highlyR

    educated'creative'class'(Florida'2002)'or'through'supporting'the'existing'people'and'firms'

    in'the'region'to'do'more'innovation'(Scott'and'Storper'2007T'and'Storper'2009).'

    Most'research'into'innovation'touts'its'benefits.'However,'there'is' less'research'

    on' the'negative'effects'of' innovation,' including' the'pressing' issue'of' today,' inequality.'

    While'innovation'fosters'economic'growth,'it'is'important'to'understand'how'the'benefits'

    of' innovation'are'distributed'in'the'society.'Around'this' issue,'here'are'some'questions'

    that'remain'unanswered:'Is'the'large'value'generated'by'innovation'being'captured'by'a'

    relatively'small'group'of'people?'Does'innovation'lead'to'an'increase'in'income'inequality'

    or'does'it' increase'the'income'of'all'groups'of'people'equally?'What'is'the'relationship'

    between'innovation'and'inequality'within'urban'economies?'

    Innovative' activities' have' become' an' important' factor' in' the' contemporary'

    economy,'since'they'bring'economic'growth'to'regions'through'different'mechanisms'such'

    as' increasing' production' efficiency,' introduction' of' new'markets,' etc.' Therefore,' local'

    governments'try'to'attract'innovative'labour'force'or'innovative'firms'to'stimulate'regional'

    growth.'In'that'case,'it'is'important'for'local'government'to'be'aware'of'the'consequences'

    of' having' innovative' activities' in' regions,' especially' negative' consequences' such' as'

    income'inequality'(if'indeed'there'is'a'relation'between'innovation'and'income'inequality).''

    Inequality' has' increasingly' become' one' of' the' problems' in' cities.' It' can' cause'

    further'problems'such'as'high'rates'of'crime,'health'problems,'etc'(Fajnzlber'et'al'2002).'

    Moreover,'places'with'higher'levels'of'inequality'have'higher'rates'of'murder,'and'people'

    say'that'they'are'less'happy'(Glaeser'et'al.,'2008).'There'are'two'streams'in'the'debate'

    on' income' inequality.' In' the' first' approach,' income' inequality' is' understood' to' be' an'

    inevitable' outcome' of' market' deregulation' and' the' drive' for' efficiency' in' the' global'

    economy.'Other'economists'have'had'second' thoughts'on' this' issue.'They'argue' that'

    income' inequality' is' not' the' outcome' market' efficiency,' instead,' the' rise' in' income'

    inequality' is'due' to' the'power' relations'between' institutions'within' the'market' such'as'

    multiRnational'companies,'workers,'customers,'etc.'In'this'approach'it'is'argued'that'gross'

    inequality' is' not' efficient' in' the' market' (Atkinson' 2015T' Kuttner' 2013).' In' the' latter'

    perspective,'local'governments'should'make'an'effort'to'reduce'the'income'gap'not'only'

    to' overcome' its' negative' social' consequences,' but' also' to' increase'market' efficiency.'

    Therefore,'local'government'should'care'about'inequality'and'be'cautious'in'supporting'

    innovative'activities'when'they'take'economic'development'policies.'

    Most' innovative' activities' are' concentrated' in' cities.' According' to' the' National'

    Household'Survey'(NHS)'2011,'around'80%'of'Canadian'population'live'in'urban'regions,'

    while'90%'of'Knowledge'Intensive'Business'Services'(KIBS)'employments'are'located'in'

    urban'regions.'KIBS'employments'are'known'as'a'representative'of'innovative'activities'

    (Breau'et' al.' 2014T'Wessel' 2013).'Similarly,' the' level' of' income' inequality' is' higher' in'

    urban'regions'than'nonRurban'ones.'Moreover,'both' innovation'(Marshall'1890T'Jaocbs'

    1970,'Glaeser'1991)'and'income'inequality'(Korpi'2008T'Baum'Snow'and'Pavan'2013)'

    have'a'positive'correlation'with'population'of'urban'region.'Therefore,'the'relation'between'

    innovation'and'income'inequality'is'studied'in'Canadian'urban+regions'in'this'research.'

    Chapter$2.$ Innovation,$Inequality$and$Mutual$Effects$

    This'chapter'discusses'geographical'distribution,'innovation'definition'and'different'

    measurement'methods'of'innovation,'which'are'presented'in'academic'literature.'Then'a'

    brief'overview'of'inequality'measures,'as'well'as'the'theories'that'are'linking'innovation'to'

    income'inequality'in'cityRregions'are'presented.''

    2.1.$ Innovation$

    2.1.1.$ Geography$of$Innovation$

    There'is'a'debate'in'the'literature'about'whether'economic'opportunities'are'evenly'

    distributed' geographically' or' if' there' are' certain' places' that' offer' greater' economic'

    opportunities.'Friedman’s'(2005)'idea'of'“the'flat'world”'focuses'on'the'global'forces'acting'

    on'economic'activities,'arguing'that'economic'activities'can'freely'move'to'different'places'

    without'being'confined' to' regional' forces.'However,'we'can'see' that' creative'activities'

    were'concentrated'in'some'places'at'different'time'periods,'such'as'Florence'under'the'

    Medici,'Paris'in'1920s,'England'during'the'industrial'revolution'and'Silicon'Valley'in'more'

    recent'times'(Feldman,'2010).'

    Some'economists,'geographers'and'historians'believe'that'most'innovations'are'

    made'within'cities'(Marshall'1890T'Jacobs'1985T'and'Glaeser'1991).'They'believe'that'the'

    agglomeration' of' people' and' firms,' and' high' levels' of' interaction' in' cities' create' an'

    environment'in'which'ideas'quickly'move'from'one'person'to'another,'and'consequently'

    help'people' to' innovate.'Access' to' knowledge' is'an' important' factor' that'makes'cities'

    conductive'to'innovations.'Furthermore,'according'to'Malmberg'and'Maskell'(1997)'most'

    innovations'come'from'the'interactive'processes'within'industrial'systems.'They'believe'

    that'the'proximity'and'short'distance'between'firms'make'the'interactive'collaboration'less'

    costly'and'smoother.'

    Creation' and' transmission' of' knowledge' is' crucial' in' the' innovation' process.'

    Philosophers'of'knowledge'make'distinction'between'knowledge'that'could'be'effectively'

  • '

    '5'

    expressed'in'a'symbolic'forms'of'representation'(explicit'knowledge)'and'other'forms'of'

    knowledge' that'cannot'be'expressed'or'codified'(tacit'knowledge)' (Polanyi'1966).'This'

    distinction'between'explicit'and'tacit'knowledge'is'important'in'innovation'studies.'Tacit'

    knowledge'has'been'known'as'the'central'component'of'the'learning'economy,'and'a'key'

    to'innovation'and'value'creation'(Polanyi'1966T'and'Gertler'2003).'Howells'(2000,'p.'53)'

    refers'to'tacit'knowledge'as'“knowRhow'that'is'acquired'via'the'informal'takeRup'of'learned'

    behaviour'and'procedures.”'Hence,'unlike'explicit'knowledge,'which'can'be'transmitted'

    through'sets'of'axioms,' rules,'algorithms'and'statements,' tacit' knowledge'can'only'be'

    transmitted'through'experience.'This'idea'makes'proximity'and'faceRtoRface'interactions'

    a' crucial' element' of' innovation,' even' with' the' growing' importance' of' long' distance'

    interactions' through' information' technology'advances.'The' idea' that' tacit'knowledge' is'

    embodied' in'human' interaction'can'help'explain'why'some'places'have'higher' rate'of'

    knowledge'creation'and'innovation'than'others.'

    Glaeser' et' al.' (1992)' believe' that' the' characteristics' of' the' cities' in' knowledge'

    production'and'diffusion'make'them'a'desirable'place'for'most'of'the'people,'despite'the'

    high'cost'of'living.'They'claim'that,'in'cities,'people'enjoy'easy'flow'of'ideas'and'improve'

    their'productivity'without'paying'for'the'knowledge.'In'their'research,'they'concluded'that'

    competition'and'diversity' in'cities'are' two' important' factors,'which' facilitate' innovation.'

    Diversified'cities'are'more'innovative'because'ideas'from'one'industry'can'be'transmitted'

    and'adopted'in'another'industry.'In'addition,'local'competition'accelerates'imitation'and'

    improvement' of' innovators’' ideas.' Researchers' acknowledge' the' role' of' knowledge'

    spillovers'and'innovation'in'the'economic'growth'by'defining'it'as'the'engine'of'growth.'

    Therefore,' numerous' research'works' stress' the' importance' of' innovation' in' economic'

    growth'in'cities.'

    The'relation'between'innovation'and'places'is'beyond'only'agglomeration'of'firms'

    and'people'in'cities.'Other'specific'attributes'of'different'places'(social,'institutional,'etc.)'

    play'an'important'role'in'the'innovation'process'(Saxenian'1996T'Storper'2009).'There'is'

    a'shift'in'innovation'analysis'approach'from'focusing'on'artefacts'and'production'side'in'

    conventional' technological' systems,' to' considering' users' and' social' context' as' an'

    important'factor'in'innovations'(Geels'2004).'The'broadened'approach'usually'is'known'

    as' sociotechnical' systems.' Considering' all' different' aspect' of' innovation,' the'

    sociotechnical' systems' approach' helps' us' to' thoroughly' understand' the' dynamic' of'

  • '

    '6'

    innovation' and' generally' technological' regimes.' This' analysis' approach' suggests' that'

    knowledge'production'and'innovation'systems'should'be'studied'within'the'social'norms'

    and'institutions'that'are'embedded'within'the'region.'Storper'(1997)'also'believes'that'the'

    knowledge'production'process'is'embedded'in'regions.'Knowledgeable'people'who'are'

    embodiments'of'the'knowledge'are'not'evenly'distributed'in'the'geographical'space.'

    In'summary,'innovation'is'not'evenly'or'randomly'distributed'in'the'space.'Despite'

    all' technological' advances' in' longRdistance' interactions,' the' capability' of' knowledge'

    creation'and'innovation'cannot'be'easily'transmitted'from'one'place'to'another.'Moreover,'

    different'attributes'of'regions'(population'density,'competition,'diversity,'institutions,'social'

    norms,'etc.)'affect'regional'innovation'systems.'

    2.1.2.$ Innovation$Definition$and$Measures$

    Researchers'have'used'different'means'to'define'the'concept'of'innovation'in'their'

    research'works,'and'consequently'these'different'definitions'lead'to'different'measures'of'

    innovation.'For'example,'Technological'product'and'process' innovations'are'defined'in'

    Oslo'Manual'by'Organisation' for'Economic'CoRoperation'and'Development'(OECD)'as'

    follows:'

    Technological' product' and' process' (TPP)' innovations' comprise'implemented'technologically'new'products'and'processes'and'significant'technological'improvements'in'products'and'processes.'A'TPP'innovation'has'been' implemented' if' it' has'been' introduced'on' the'market' (product'innovation)'or'used'within'a'production'process'(process'innovation).'TPP'innovations' involve' a' series' of' scientific,' technological,' organizational,'financial'and'commercial'activities.'The'TPP'innovating'firm'is'one'that'has'implemented'technologically'new'or'significantly'technologically'improved'products'or'processes'during'the'period'under'review'(Oslo'Manual,'2005,'p.25).'

    However,'a'broader'definition'is'provided'by'Schumpeter'(1934),'in'which'he'also'

    included' three'additional'elements' to' the'Oslo'TPP' innovation'definition.' In'addition' to'

    product'and'process'innovation,'Schumpeter’s'definition'also'includes'opening+of+a+new+

    market,'development+of+new+source+of+supply'and'changes+in+an+industrial+organisation.'

  • '

    '7'

    Numerous' variables' have' been' used' for' regional' innovation' measurementT'

    however,'as'discussed'in'the'following'paragraphs,'none'of'them'are'able'to'include'all'

    different'types'of'innovation.'Each'definition'focuses'on'a'specific'definition'and'type'of'

    innovation.' Therefore,' researchers' usually' use'multiple' variables' to' measure' regional'

    innovation.''

    One'of'the'parameters'that'is'used'to'measure'the'level'of'innovation'in'a'region'

    is'number'of'patents'registered'per'millions'of'population.'Sonn'and'Storper'(2008)'used'

    the'number'patents'and'their'citation'in'the'United'States'Patent'and'Trademark'Office'

    (USPTO)' as' a' measure' of' innovation' to' investigate' the' importance' of' proximity' on'

    knowledge'production.'According'to'the'fact'that'a'significant'percentage'of'patents'are'

    produced'by'a'group'of'inventors,'they'proposed'a'method'to'assign'a'fraction'of'patent'

    to'the'city'of'each'team'member.'For'instance,'if'a'team'of'three'inventors'from'Toronto,'

    Montreal'and'Ottawa'create'a'patent,'each'city'will'have'one'third'of'the'patent'in'counting'

    number'of'patents.'

    While'many'other'researchers'have'used'this'method'in'their'research'work,'there'

    are' some' limitations' in' using' the' number' of' patents' per'million' in' the' population' as' a'

    measure'of'innovation.'Despite'Sonn'and'Sorper'(2008)'having'used'patent'counts'in'their'

    research,'they'have'mentioned'limitations'of'this'method.'First,'some'patents'have'never'

    been'commercialized'and' therefore'have'not'had'any' impact'on' the'economic'output,'

    while' they' are' counted' as' a' representative' of' innovation.' Second,' the' propensity' of'

    innovators' to' patent' their' knowledge' production' varies' among' different' sectors.' For'

    instance,' innovators' in' service' sectors' are' less' likely' to' patent' their' work' than' in'

    manufacturing,'despite' the' fact' that'knowledge'production' in' the'service'sector'has'an'

    increasing'significance'in'the'contemporary'economy.'

    Moreover,'Hall'et'al.'(2013)'claim'that'the'share'of'firms,'which'do'not'patent'their'

    knowledge'production,'is'significant,'because'patenting'needs'enough'time'and'money,'

    and' familiarity' with' the' process,' which' makes' the' process' difficult' for' small' firms.'

    Therefore,' using' number' of' patents' as' a'measure' of' innovation'will'miss' a' significant'

    number'of'innovations,'which'are'not'registered'as'a'patent.'Lee'(2011)'also'stated'that'

    this'measure'has'failed'to'account'for'innovations,'which'are'unlikely'to'be'patented,'such'

    as'process'innovations.'

  • '

    '8'

    Another'measure'of'innovation,'which'has'been'used'by'some'researchers,'is'the'

    proportion'of'employees'working'in'those'industries,'which'have'a'high'rate'of'innovation'

    and'knowledge'production.'This'measure'is'capable'of'capturing'the'innovations'that'are'

    not'being'patented.'Lee'(2011)'used'proportion'of'such'employment'to'measure'regional'

    innovation' in' European' cities.' He' used' employment' in' five' overlapping' categories' of'

    knowledgeRbased'industries'provided'by'Eurostat:'knowledgeRintensive'financial'services,'

    highRtech' knowledgeRintensive' services,' other' knowledgeRintensive' services' and' highR

    tech'manufacturing.'However,'he'claims'that'these'classifications'are'too'broad'while'what'

    is'counted'as'innovationRrelated'employment'within'each'sector'may'be'very'different.'For'

    instance,'he'states'that'this'measure'is'not'able'to'distinguish'between'the'head'office'

    employees'of'a'firm'and'the'manufacturing'labours,'whereas'the'former'may'gain'more'

    from'innovation'than'the'latter.'In'the'Canadian'context,'this'is'more'problematic'because'

    in' Canadian' Census' data' all' the' five' categories' of' knowledgeRbased' industries' are'

    aggregated'in'one'category'of'knowledgeRintensive'business'services.'

    Gertler'et'al.'(2002)'measured'innovation'through'location'quotient'in'the'highRtech'

    industries.' They' defined' highRtech' industries' in' Canada' based' on' Standard' Industrial'

    Classification' (SIC),'which' includes' employment' in' industries' related' to' aircraft,' office,'

    electrical,' and' scientific' equipment' manufacturing,' bioRmedical,' telecommunications,'

    computer,'engineering'and'scientific'services'and'film.'Hall'and'Khan'(2008)'also'added'

    communication' equipment'manufacturing,' electrical' wholesales,' employment' agencies'

    and'management'consulting'to'the'definition'of'highRtech'industries'to'capture'the'breadth'

    of'highRtech'activity.'

    On' the' other' hand,' Chapple' et' al.' (2004)' explored' the' possibility' of' using'

    occupations' rather' than' industries' with' the' objectives' of' monitoring' and' targeting'

    economic' performance.' They' introduced' a' list' of' occupations,' which' are' presented' in'

    Table'2.1,' to'measure'the' level'of'highRtech'activities'of'cities'and'compare'the'results'

    with'other'measures.'As'these'occupations'are'extensively'dependent'on'creativity'and'

    innovation,'the'share'of'employees'working'in'these'occupations'(rather'than'highRtech'

    industries)' can' be' a' parameter' that' represents' the' level' of' innovation.' As' discussed'

    above,' the' problem' of' using' employment' in' highRtech' industries' as' a' measure' of'

    innovation' is' that' all' employees' working' in' a' highRtech' industry' are' considered' as'

    innovative'employees,'including'some'nonRinnovative'workers'who'are'doing'routine'jobs'

  • '

    '9'

    in'the'industry.'Measuring'innovation'based'on'occupations'may'overcome'this'problem.'

    Someone'who' has' a' nonRinnovative' job' in' a' highRtech' industry' does' not' count' as' an'

    innovative'worker.'

    Share'of'employment'in'KnowledgeRIntensive'Business'Services'(KIBS)'is'another'

    measure'of'innovation'used'in'literature'(Breau'et'al.'2014T'Wessel'2013)'because'KIBS'

    sector'produces'and'diffuses'knowledge,'which'is'crucial'to'innovation.'Muller'and'Zenker'

    (2001)' studied' the' interactions' between' KIBS' and'manufacturing' smallR' and'mediumR

    sized'enterprises'and'concluded'that'this'type'of'interaction'stimulates'the'generation'and'

    diffusion'of'knowledge'within'innovation'systems'at'both'national'and'regional'level.'They'

    showed'that'KIBS'play'an'important'role'in'innovation'systems'not'only'by'“transmitting”'

    knowledge,' but' also' with' their' crucial' role' in' “knowledge' reRengineering”' (i.e.' the'

    appropriation'of'knowledge).'KIBS'firms'enhance'innovation'capacity'of'their'client'firms'

    and'get' stimuli' for' their'own' innovations.' In'Canada,'Breau'et'al.' (2014)'have'defined'

    innovation'as'the'percentage'of'employees'in'KIBS'in'Canadian'cities.'They'have'used'

    code'54'of'North'American'Industry'Classification'System'(NAICS).'Table'2.2'shows'the'

    detailed'breakdown'of'this'industry'sector.'

    As'discussed'above,'there'are'numerous'variables'in'measurement'of'innovation'

    and'knowledge'production.'Due'to'the'limitations'of'each'of'these'methods,'it'would'be'

    more'useful'to'improve'the'analysis'through'using'multiple'measures'of'innovation.'In'this'

    2.2.2.$ Inequality$Measure$

    Many'different'measures'have'been'introduced'for'inequality'measurement'such'

    as'Gini'coefficient,'standard'deviation,'Theil'index,'and'decile'ratio.'These'measures'are'

    not'different'ways'of'measuring' inequalityT' they'are'measuring'different'definitions'and'

    dimensions' of' inequalityT' however,' it' has' been' shown' that' there' is' a' high' correlation'

    between'these'measures'(Allison'1978).'

    De' Maio' (2007)' conducted' research' on' the' different' methods' of' inequality'

    measurement.'He'believes'that'the'most'popular'parameter'in'measuring'inequality'is'the'

    Gini'coefficient.'The'strength'of'the'Gini'coefficient'is'that'it'considers'different'aspects'of'

    inequality' such' as' inequality' around' mean' and' at' both' ends' of' income' distribution.'

    However,' its' weakness' is' that' it' cannot' differentiate' between' different' aspects' of'

    inequality,'for'example,'whether'the'rich'are'richer'or'the'poor'are'poorer.'Hence,'there'

    might'be'a'difference'between'characteristics'of'two'income'distributions'while'they'have'

    a'same'Gini'coefficient.'Moreover,'researchers'should'be'aware'of'the'fact'that'the'Gini'

    coefficient'is'the'most'sensitive'inequality'measure'to'the'distribution'around'the'middle'

    part'of'the'income'distribution.'

    Another' inequality' measure,' which' has' been' used' commonly' in' literature,' is'

    Percentiles' ratio.' These' are' simple' measures' that' give' the' sense' of' how' income' is'

    distributed'among'the'study'population.'They'help'researchers'understand'whether'the'

    change'in'inequality'is'because'of'the'increase/decrease'in'the'top'or'bottom'of'the'income'

    distribution.'

    Most'of'the'researchers'studying'inequality,'prefer'to'use'more'than'one'measure'

    of' inequality' to' be' able' to' capture' different' aspects' of' income' inequality,' such' as'

    2.3.$ Relationship$between$Innovation$and$Income$Inequality$

    As' discussed' above,' innovation' is' known' as' the' engine' of' growth' for' regional'

    economies.'On'the'other'hand,'innovation'and'knowledge'production'in'cities'affects'the'

    distribution'of'earnings.'Although' the'discussion'on' the'effect'of' innovation'on' income'

    inequality' has' been' increasingly' considered' in' the' literature' because' of' the' inequality'

    growth'in'the'recent'decades,'it'is'not'a'new'concept.'It'was'documented'in'the'Communist'

    Manifesto'as'follow:'

    “The' bourgeoisie' cannot' exist' without' constantly' revolutionizing' the'instruments' of' production,' and' with' them' the' whole' relations' of'society...Constant'revolutionizing'of'production,'uninterrupted'disturbance'of'all'social'conditions,'everlasting'uncertainty'and'agitation'distinguish'the'bourgeois'epoch'from'all'earlier'ones”'(Marx'and'Engels,'1848)'

    Numerous' theories' have' been' introduced' in' the' recent' decades' regarding' the'

    distributional'effect'of' innovation'on'earnings'at'a'national'scale,'which'mostly'predicts'

    that'the'innovations'increase'the'earnings'inequality.'One'of'the'most'common'theories'

    is'skillRbiased'technological'change'(SBTC)'(Berman'et'al.'1997).'

    According'to'SBTC,'the'introduction'of'new'technology'–especially'in'the'form'of'

    computers,'information'and'communications'technology–'increases'the'demand'of'highly'

    skilled' labour'and'decreases' the'demand'of' less'skilled' labour,'since'on'one'hand'the'

    operation'of'new'technologies'needs'highly'skilled'and'educated'labour,'and'on'the'other'

    hand'new'technologies'usually'improve'productivity'and'consequently'decrease'the'need'

    for' less' skilled' labour.' Therefore,' individuals' with' higher' levels' of' education' and'

    experience'will'have'more'job'opportunities'and'will'experience'an'increase'in'earnings'

    while'those'who'are'not'qualified'to'work'with'the'new'technology'will'lose'their'job'or'see'

    a'reduction'in'their'earnings.'

    As'an'example'of'SBTC,'Wheeler'(2005)'showed'that'the'introduction'of'computer'

    to' industries' increased'the' level'of' income'inequality' in' the'United'States'from'1983'to'

    2002.'This'increase'in'income'inequality'was'more'related'to'dispersion'of'income'within'

    industries' rather' than' between' industries.' His' findings' show' that' there' is' a' positive'

    correlation'between'withinRindustry'inequality'and'frequency'of'computer'usage'and'also'

    ratio' of' employees'with' a' college' degree.' His' findings' are' consistent' with' skillRbiased'

    technological'change'theory.'The'findings'indicate'that'during'the'period'that'the'computer'

    was'introduced'as'a'new'technology,'industries'which'needed'more'use'of'computers'had'

    higher'income'inequality,'because'people'who'were'highly'skilled'to'work'with'a'computer'

    would'have'an'earning'reduction'or'a'relative'lag'in'salaries'relative'to'those'who'have'

    computer'skill,'which'leads'to'an'increase'in'income'inequality.'

    Acemoglu'and'Autor'(2010)'argue'that'although'SBTC'was'notably'successful'in'

    explaining' the'effect'of' innovations'and'new' technologies'on'earnings'distribution,' it' is'

    silent'when'it'comes'to'the'empirical'developments'of'the'last'three'decades,'which'are'

    listed'as'follows'(p.'1157):'

    1.' Significant'declines'in'real'wages'of'low'skill'workers,'particularly'low'skill'malesT'

    2.' NonRmonotone'changes'in'wages'at'different'parts'of'the'earnings'distribution'during'different'decadesT'

    3.' BroadRbased'increases'in'employment'in'high'skill'and'low'skill'occupations'relative'to'middle'skilled'occupationsT'

    4.' Rapid'diffusion'of'new'technologies'that'directly'substitute'capital'for'labor'in'tasks'previously'performed'by'moderately'skilled'workersT''

    5.' Expanding'offshoring'in'opportunities,'enabled'by'technology,'which'allow'foreign'labor'to'substitute'for'domestic'workers’'specific'tasks.'

    To'explain' the'above' issue,'Acemoglu'and'Autor' (2010)' introduced' taskRbased'

    framework' to' effectively' explain' the' effect' of' innovations' on' earnings' inequality.' They'

    consider'the'element'of'tasks'in'addition'to'technology'and'skills.'In'this'theory,'the'main'

    focus'is'on'the'interaction'between'technology,'skills'and'tasks.'

    Unlike' SBTC' theory,' instead' of' simply' claiming' that' people' with' a' higher'

    educational'degree'will'be'able'to'work'with'new'technologies'and'be'rewarded,'the'taskR

    based'framework'defines'new'tasks'that'are'introduced'by'innovation'in'an'industry.'Then'

    it' relates'different' tasks' to'different'skills'and'explains'how'earnings'within'an' industry'

    become' polarized' between' groups' of' workers' with' different' skills' with' respect' to' the'

    changing'nature'of'the'tasks.'

    'TaskRbased'framework'argue'that'innovations'and'new'technologies'will'replace'

    human'labour'in'some'manual'routine'tasks'with'ICTs,'but'human'labour'is'still'needed'in'

  • '

    '16'

    nonRroutine' tasks,' namely,' (1)' complex' and' abstract' tasks' and' (2)'manual' tasks.' The'

    former'includes'processing'of'information,'understanding'specialized'and'highly'technical'

    subjects,'problem'solving'and'communicating,'and'the'latter'includes'tasks'that'require'

    inRperson'interaction'and'physical'abilities.'Therefore,'as'a'consequence'of'diminishing'

    routine'jobs'in'the'middle'of'the'wage'distribution,'the'labour'force'will'be'polarized'into'

    two'tasks'at'both'ends'of'earning'distribution.'

    Tacit'knowledge'is'crucial' in'these'nonRroutine'jobs,'and'their'know9how'cannot'

    easily'be'codified'as'explicit'knowledge.'Hence,'the'increasing'importance'of'nonRroutine'

    jobs' acknowledge' the' idea' that' innovations' are' mostly' introduced' and' used' in' cities,'

    because'cities'allow' for' faceRtoRface' interactions'between'numerous' firms'and'people,'

    which' is' important' in' production' and' transmission' of' tacit' knowledge' (as' discussed' in'

    section'2.1.1).'

    Lee' (2011)'also' looked'at' the' relation'between' regional' innovation'and' income'

    inequality' through'analysis'of'European'cities.'He'described' five'mechanisms,' through'

    which'innovation'leads'to'income'inequality'(p.'3R4).'

    1.' Innovation'leads'to'higher'productivity'in'the'production'process'and'innovative'firms'and'workers'will'benefit'in'the'form'of'wage'gain'

    2.' There'may'be'a'greater'dispersion'of'income'within'the'innovative'industry'sector,'which'may'polarize'the'pay'structure'of'the'industry'

    3.' If'the'innovations'are'diffused'locally,'SBTC'process'will'affect'the'regional'inequality'

    '4.' Innovative'regions'may'attract'highly'skilled'and'highly'paid'labour'from'other'regions.'This'process'will'also'increase'the'number'of'innovations'

    5.' When'innovation'raises'the'wage'of'certain'group'of'people,'it'will'stimulate'the'need'for'more'lowRpaid'service'sector'jobs'

    However,'his'first'four'theories'are'very'similar'to'the'aforementioned'theories,'the'

    fifth'one'explains'that'the'high'wage'innovative'jobs'will'attract'workers'to'the'low'wage'

    service'jobs'to'provide'services'for'highlyRpaid'innovative'people.'These'jobs'include'food'

    service'workers,'security'guards,' janitors,'cleaners'and'gardeners,'home'health'aides,'

    childcare'workers,'and'personal'appearance'and'recreational'occupations.'

  • '

    '17'

    Similarly,'Florida'(2002)'in'The+Rise+of+Creative+Class,'explains'that'a'significant'

    growth'in'the'creative'class'necessitates'growth'in'lowRskilled'lowRwage'labours'to'take'

    care'of'the'creative'class'and'“do'their'chores”'(p.71).'Therefore,'according'to'his'theory'

    the'growth'of'employment' is'mainly' in'highly'paid'creative'class'occupations'and' lowR

    wage' service' sectors,' which' provide' services' to' highRincome' creative' workers.' This'

    pattern'of'growth'will'lead'to'polarization'and'earnings'inequality.'One'of'the'reasons'that'

    his'idea'in'supporting'creative'class'has'been'criticized'by'Peck'(2005)'is'that'the'rise'of'

    creative'class'neglects'the'issues'of'intraRurban'inequality.'

    Through'these'different'mechanisms,' innovation'can'increase' income'inequality'

    either'within'innovative'industries,'or'between'innovative'industries'and'those,'which'are'

    not'heavily'dependent'on'innovation'and'knowledge'production.'Increase'in'the'income'

    of'innovative'workers'can'increase'the'demand'for'lowRpaid'service'workers.'Workers'who'

    are'attracted' to' the' low'paid'service'sector' jobs'could'have'been'displaced' from'other'

    industrial' sectors' in' the' region,' therefore' through' this'mechanism' innovative' industries'

    and' low' paid' service' sector' will' experience' economic' growth,' while' other' industries'

    potentially' decline.' The'SBTC' theory' suggests' that' income' inequality' increases'within'

    industries'because'workers'within'an'industry'will'experience'differential'rises'(or'fall)'in'

    their'income'based'on'what'kind'of'tasks'they'are'doing'and'how'valuable'they'are.'

    The'presence'of'KIBS'sectors'can'also'affect'the'income'distribution'in'economic'

    regions.'KIBS'industries'can'perform'the'research'and'development'outsourced'by'other'

    industries,'create'knowledge'and'innovate'new'industries.'They'also'provide'the'support'

    activities' for' other' industries' in' their' innovation' progress' such' as' legal' services,'

    advertising,'infrastructures'design,'etc.''

    Concentration'of'KIBS'activities'can'increase'productivity'within'the'KIBS'sector'

    itself,'and'within'the'firms'in'other'industry'sectors'(which'enjoy'KIBS'services'benefits),'

    through'different'mechanisms'(Wessel'2011,'p.'1086):'

    •' Externalization+of+activities:'reduction'in'average'cost'of'production'through'outsourcing'specific'tasks'or'services'to'other'industrial'sectors'of'the'economyT'

    •' Spatial+reorganization+of+production:'reallocating'different'production'tasks'to'different'geographical'placesT'

    •' Utilization+and+development+of+new+technologies:'introduction'of'new'technologies'through'R&D'activities'within'KIBS'sector'or'in'partnership'with'other'industriesT'

    •' Participation+in+cross9border+networks:'expanding'demand'market'or'suppliers'of'an'industry'through'their'crossRborder'networkT'and'

    •' Adoption+of+flexible+working+practices:'allowing'workers'to'work'remotely'or'reduced'hours.'

    Wessel'(2011)'claims'the'KIBS'sector'is'an'important'distributive'force.'It'divides'

    the' lowRwage' and' the' highRwage' segments' of' economy' by' specialization' and'

    reorganization' of' production.' For' instance,' different' processes' of' production' that'were'

    formerly' done' within' a' single' firm' will' be' separated' to' be' done' in' different' firms' and'

    industries' or' different' geographical' locations.' Through' the' products' or' services' value'

    chain,'processes,'which'add'a'high'value' to' the'product,'will' create'highRincome' jobs,'

    whereas' ones,' which' add' a' low' value' to' the' product,' will' create' lowRincome' jobs.'

    Therefore,' KIBS' activities' can' increase' the' income' inequality' in' other' industries.'

    Moreover,'partly'because'of'the'use'of'flexible'labour'there'is'a'change'in'the'payment'

    scheme,' union' density,' union' coverage' and' legislative' intervention' in' KIBS' sector.' A'

    consequence'of'such'adjustment'is'a'growing'gap'between'income'in'KIBS'and'the'rest'

    of'the'economy.'

    2.4.$ Effect$of$Inequality$on$Innovation$

    Among' the' literature' considering' the' relationship' between' inequality' and'

    innovation,'most' researchers' do' not' empirically' investigate' to' find' out' which' of' these'

    parameters' affects' the' other' one.' There' could' be' a' mutual' effect' between' income'

    inequality' and' innovation,' and' it' is' an' open' question' whether' inequality' matters' for'

    innovation,'or'innovation'matters'for'inequality'(or'whether'they'are'mutually'dependent'

    to'each'other).'For'instance,'Tselios'(2011)'analyzed'microeconomic'data'of'102'Western'

    European'regions'over'the'period'of'1995'to'2000,'to'find'out'whether'inequality'is'good'

    for' innovation' or' not.' He' concluded' that' an' increase' in' a' region’s' inequality' favours'

    innovation.' To' find' out' which' one' is' affecting' the' other' one,' he' has' done' a' Granger'

    causality' test' between' 1995' and' 2000.' Tselios' concluded' that' the' casual' relation' of'

    innovation'and'inequality'varies'across'space,'because'innovation'has'local'character'and'

  • '

    '19'

    cumulative' nature.' In' other' words,' in' some' regions,' inequality' in' 1995' caused' more'

    innovation'in'2000'and'in'others'more'innovation'in'1995'caused'more'income'inequality'

    in'2000.'

    Some'of'the'theories'on'the'effect'of'innovation'on'income'inequality'are'explained'

    above.'In'this'section,'some'of'the'theories'on'the'effect'of'inequality'on'innovation'are'

    studied.'

    Income'inequality'could'have'a'positive'or'negative'effect'on'innovation'through'

    its'direct'impact'on'market'size'and'price'effect'(Bertola'et.'al.'2006).'On'one'hand,'the'

    more' unequal' the' distribution' of' income'means' the' smaller' regional'market' for' a' new'

    product,' because' when' the' income' distribution' is' unequal,' only' a' small' number' of'

    consumers'can'afford'to'buy'the'newest'products.'Therefore,'the'markets'of'new'products'

    –and'consequently'innovative'industries–'grow'slowly.'This'mechanism'is'valid'only'when'

    the'markets'are'regional.'

    On' the' other' hand,' when' the' price' effect' of' income' inequality' becomes'more'

    dominant' than' the' market' size' effect,' one' can' argue' that' inequality' will' accelerate'

    innovations,'since'high' income'consumers'have'a'very'high'willingness'to'pay'for'new'

    products'and'services.'In'addition,'the'relatively'rich'individuals'are'more'likely'to'pay'for'

    better' technologies,' therefore' it' stimulates' the' creative' class' to' innovate' more' in'

    competition'with'each'other'(Vernon'1972).'

    Another'theory'explaining'the'effect'of'inequality'on'innovation'is'Werner'Sombart'

    Thesis' (1913),'Luxury+and+Capitalism.' It'explains' the'mechanism' through'which' luxury'

    consumptions' by' ‘rich’' people' leads' to' emergence' of' new'markets' and' consequently'

    innovativeness.'Therefore,' inequality'will'provide'an'appropriate'environment'–which' is'

    polarized'wealth'distribution–'for'production'and'consumption'of'luxury'materials.''

    Overall,' all' the' aforementioned' theories' in' this' section' implicitly' have' the'

    assumption' that' local' factors'are'more'dominant' than' interRregional' factors' in' the' local'

    market,'whereas'globalization'and'availability' of' transRregional'markets' through' cheap'

    transportation' cost' could' reduce' the' effect' of' regional'market' size' and' price' effect' on'

  • '

    '20'

    innovation.'To' the'extent' that' innovative' firms'are'not' limited' to' their' regional'markets,'

    they'will'be'able'to'sell'their'products'or'services'to'‘rich’'people'in'other'regions.'

    2.5.$ Patent$Policy$and$Capital$Income$Inequality$

    The'focus'of'this'research'is'on'employment'income'(or'wage)'inequalityT'however,'

    another'important'aspect'of'economic'inequality'lies'in'the'capital'income'inequality.'For'

    example,'Reed'et'al.'(2001)'show'that'oneRquarter'of'the'increase'in'income'inequality'in'

    the'1990s' in' the'US' is'due'to' the'capital' income' inequality.' Innovation'also'affects' the'

    distribution'of'capital'income.''

    Chu'(2010)'conducted'a'research'on'the'effect'of'patent'policy'on'capital'income'

    inequality,' and' he' concluded' that' strengthening' patent' protection' increases' economic'

    growth'through'encouraging'firms'to'spend'more'on'research'and'development,'and'also'

    increases'capital'income'inequality'by'increasing'the'rate'of'return'on'capital.'This'higher'

    return'on'assets'leads'to'an'increase'of'the'assetRwealthy'households’'income'relative'to'

    assetRpoor'households.'

    On' the'other' hand,'Hatipoglu' (2008)' studied' the'effect' of' income' inequality' on'

    innovation'within'different' patent' policies.'As'discussed'above' firms'are'more' likely' to'

    innovate'where' the' income' inequality' is'high,'because' they'have' their'market' for'new'

    products'among'highRincome'consumers.' In'addition,'Hatipoglu'believes' that'when' the'

    income' inequality' is' low,' longRterm'patent'would'be'an' incentive' for' innovative' firms' to'

    spend'more' on' research' and' development' because' it' increases' the' profitability' of' an'

    innovation'by'increasing'the'likelihood'of'the'benefit'from'a'future'demand'jump'in'sales'

    to'the'poor.'These'different'ideas'confirm'the'importance'of'policy'making'in'minimizing'

    the'side'effects'of'innovation'while'the'economy'is'enjoying'its'benefits.'Specifically,'when'

    policy'makers'use'patent+policy'as'an'instrument'to'increase'research'and'development'

    and'consequently'economic'growth,'they'need'to'take'into'account'the'potential'negative'

    3.1.$ Census$Metropolitan$Areas$and$Census$Agglomerations$Boundaries$

    The' units' of' analysis' in' this' research' are' Canadian' cities.' These' entities' are'

    defined' by' Statistics' Canada' as' Census' Metropolitan' Area' (CMA)' or' Census'

    Agglomeration'(CA)'based'on'their'population.'Statistics'Canada'defines'CMA'and'CA'as'

    follows:'

    A' census' metropolitan' area' (CMA)' or' a' census' agglomeration' (CA)' is'formed'by'one'or'more'adjacent'municipalities'centred'on'a' large'urban'area'(known'as'the'urban'core).'A'CMA'must'have'a'total'population'of'at'least' 100,000' of' which' 50,000' or' more' must' live' in' the' urban' core.'A'CA'must'have'an'urban'core'population'of'at'least'10,000.'To'be'included'in'the'CMA'or'CA,'other'adjacent'municipalities'must'have'a'high'degree'of'integration'with'the'central'urban'area,'as'measured'by'commuting'flows'derived'from'census'place'of'work'data.'

    Inclusion'of'municipalities'around' the'urban'core'depends'on' the'degree'of' integration'

    with'the'central'urban'area,'which'is'measured'by'daily'commuting'flow.'Therefore,'it'is'

    not'unexpected' to'see'changes' in'Canadian'CMAs/CAs'boundaries' in'20'years'of' the'

    analysis'period'from'1991'to'2011.'These'changes'are'applied'every'5'years'prior'to'the'

    census'years'according'to'the'commuting'patterns'in'the'previous'census'data.''

    A' unique' CMA/CA' geographical' boundary' does' not' have' a' constant' identity'

    independent'from'its'social'and'economic'interactions.'When'the'interactions'between'a'

    CMA/CA' with' a' nearby' region' increases' between' two' census' years,' the' initial'

    geographical' boundaries' do' not' represent' the' same' characteristics' at' both' instances.'

    Therefore,' in' this'research,'boundaries'of'each'CMA/CA'for'crossRsectional'analysis' in'

    each'census'year'is'considered'as'the'CMA/CA'boundaries'defined'by'Statistics'Canada'

    at'the'year'of'analysis.'Similarly,'in'the'longitudinal'analysis'CMA/CA'boundaries'of'each'

    census'year'is'used'for'that'specific'year,'in'other'words'functional'economic'regions'with'

    dynamic'boundaries'over'time'are'considered'as'analysis'entities,'not'fixed'territories.'For'

    instance,'as'the'boundaries'of'Edmonton'have'been'changed'slightly'from'2006'to'2011,'

    when'I'perform'an'analysis'on'Edmonton'from'2006'to'2011,'I'use'boundaries'defined'by'

    Statistics'Canada'in'each'census'year'for'the'corresponding'census'year.'

    Along'with'the'changes'in'CMA/CA'boundaries,'some'CAs'has'been'merged'to'

    other'CMAs/CAs'and'they'do'not'exist'as'an'independent'CA'in'some'census'years'of'

    the'analysis.'In'addition,'some'CAs'are'introduced'sometime'after'1991.'Newly'emerged'

    CAs' are' excluded' from' the' analysis' because' in' longitudinal' analysis'CMAs/CAs' in' all'

    census' years' from' 1991' to' 2011' are' compared' with' each' other.' In' addition,' as' the'

    longitudinal'analysis'should'be'consistent'with'the'crossRsectional'analysis'in'each'census'

    year,'the'identical'group'of'CMAs/CAs'are'used'in'crossRsectional'analysis.'For'instance,'

    Miramichi'was'introduced'as'a'CA'in'2006,'whereas'it'was'not'considered'as'a'separate'

    CA'before'2001.'Therefore,'it'has'been'excluded'from'the'analysis.'

    CAs/CMAs'that'existed'before'and'merged'into'another'CMA/CA'sometime'after'

    1991' are' also' excluded' from' the' analysis.' One' might' consider' the' geographical'

    boundaries'of'merged'CAs/CMAs'as'a'single'CA/CMA'in'all'Census'years'(even'when'

    Statistics' Canada' did' not' consider' them' as' a' single' CA).' In' this' research,' these'

    uncommon' CAs/CMAs' are' excluded' from' analysis' and' merged' CMAs/CAs' are' not'

    considered' as' a' single' CMA/CA' in' all' years,' because' when' we' are' studying' a'

    geographical'area'as'a'single'entity'the'economic'activities'of'all' the'people'within'that'

    area' should' be' linked' together' to' a' specific' degree.' For' instance,' Magog' was' an'

    independent' CA' in' 2001,' after' which' it' was' merged' into' Sherbrook.' It' should' not' be'

    included'in'Sherbrook'for'analysis'before'2006'because'according'to'Statistics'Canada'

    the'social'and'economic'relation'between'Magog'and'Sherbrook'was'not'strong'enough'

    to'consider'them'as'one'CMA,'even'though'Magog'became'a'part'of'Sherbrook'CMA'after'

    2006.'

    According'to'the'aforementioned'selection'process'of'units'of'analysis,'among'all'

    CMAs/CAs'defined'in'the'census'years'from'1991'to'2011,'29'CAs'are'excluded'from'the'

    analysis'which'are'shown' in'Table'3.1'with' their' total'population' in'2011.'As' the' table'

    shows,'other'than'SaintRJérôme,'which'has'the'population'of'68,456'and'has'merged'into'

    Montréal'after'1991,'all'these'CAs'has'the'population'of'less'than'30,000.'A'list'of'all'130'

    3.2.$ Innovation$Measure$

    As'discussed'in'Chapter'2,'there'are'numerous'variables'used'by'researchers'to'

    measure' the' level' of' regional' innovation.' Among' these' measures,' three' of' them' are'

    selected' to' be' used' in' this' researchT' (1)' ratio' of' employees' in' highRtech' occupations'

    (defined'by'Chapple'(2004)),'(2)'ratio'of'employees'working'in'highRtech'industries'(used'

    KnowledgeRIntensive'Business'Services'(KIBS)'industries.'

    HighRtech' occupations' are' defined' according' to' Standard' Occupational'

    Classification' (SOC)' system,' whereas' in' Canadian' Census,' occupations' are' defined'

    based'on'National'Occupational'Classification'(NOC).'HighRtech'occupations'which'are'

    provided'based'on'SOC'are'transformed'into'NOC'classification'system.'Moreover,'the'

    NOC' classification' has' slightly' been' changed' from' 1991' to' 2011,' but' the' structure' of'

    classification' has' remained' constant3.' Therefore,' the' highRtech' occupations' list' is'

    consistent'among'all'analysis'census'years.'

    on'SIC'classification,'however'the'industrial'classification'in'Canadian'Census'changed'

    from' SIC' to' North' American' Industrial' Classification' System' (NAICS)' in' 2001.' This'

    transition' from' SIC' to' NAICS' changed' the' structure' of' the' classification' significantly.'

    Therefore,'being'consistent' in'analysis'would'be'challenging'when'using' the' industrial'

    year'that'includes'the'employment'data'based'on'both'NAICS'and'SIC'classification.'

    The' ratio' of' KIBS' employment' based' on' NAICS' classification' is' defined' as'
