2. Growth in the knowledge economy
• Sustained increases in the demand and supply of skilled labour
– Technology
• New technology - skill complementarity (Goldin & Katz, 1998)
• Displacement of routine tasks (Manning & Goos, 2003; Autor, Levy, Murnane, 2003)
– Globalisation
• Tradewith labour intensive markets (Autor, Dorn, Hanson, 2013)
– Rapid expansionof higher education
• Skills matter for productivity
– Labourquality directly influences productivity
– As well as via spillovers/knowledgediffusion
• And the output of skilled labour has “investment” properties
– Intangiblesseen as the “missing input” in the knowledge economy
• Stems fromthe ICT-growth literature(O’Mahony & van Ark, 2003)
• Growing recognition of the importance of management and organisation (Black and Lynch,
2001; Basu et al, 2003; Bloomet al, 2007 )
• R&D literature

3. How much do intangibles matter?
• Macro studies have looked at intangibles in the national accounting
framework (Corrado et al, 2005; Giorgio Marrano et al, 2009; Haskel
et al, 2011)
– Economic competencies, Innovative property, Computerized information
– Treated as intermediates
– Need to be capitalised
• Magnitudes
– Evidence for the US: Corrado et al (2009) estimate around $800 billion are missing from
US GDP
– Evidence for Europe: Taking a relatively broad definition, estimates range from 7-12 per
cent of GDP over the 1990s and early 2000s (Roth and Thum, 2010)
– Evidence for the UK:
• Giorgio Marrano et al (2009) find GVA in market sectors is understated to the tune of around 6
per cent in 1970, increasing to 13 per cent by 2004.
• Haskel et al (2011) find investments in intangibles to be as important as tangibles in the 1990s
and MORE importantfrom2000 onwards.
• Dal Borgo et al (2013) analysing input-outtables suggestorganisationalinvestmentaccounts
for morethan half of UK intangible investment(mostly management & training).

4. More to learn from looking at firms’
use of intangibles
• Develop new data on firms’ knowledge assets
– Based on similar methods to those used in the recent macroeconomic
literatureon intangibles
– Providing a bottom-up approachto evaluatingpotentialmagnitudes and
patterns in intangibleinvestmentand capital
– Facilitatingnew analysis
• Study the role of knowledge assets in driving growth
– Within the unifying framework of the macroeconomic intangiblesliterature
– But at a more disaggregate level
– Within regression analysisframeworks

5. Measuring firms’ investments in intangibles
• Evaluate firms’ expenditures on intangibles:
– Using information on firms’ purchases of intangibles
– And costs of workers undertaking “intangible” tasks
– Evaluate investment share
• using common assumptions in the literature
– Capitalise investment flow (PIM)
• using depreciation rates in the literature
• Data sources:
– Annual Respondents Database
– Annual Survey of Hours and Earnings

6. Occupations involved in the
production of knowledge assets
• Digitised Information
– ICT professionals& managers
• Intellectual Property
– Natural& SocialScience professionals & managers
– Architects, Engineering professionals, Business research professionals
– Highly skilled artistic workers, designers
• Organisational Capital (Economic Competencies)
– HRM: human resources managers and directors, vocational
and industrialtrainers
– BRAND: sales, marketing, advertising & public relationsmanagers
– MANAGEMENT: chief executive and senior officials, production&
operationsdepartment managers
For related , but broader, occupational classifications of occupations involved in the production of intangibles see FP7 INNODRIVE and

14. Firms, intangible assets and productivity
• Clear role for intangibleassets in explainingfirms’ productivityperformance
• Potentiallyat least as importantas physicalcapitalin determining growth
– particularlyin knowledge intensivesectors
• Organisationalcapitalis importantin all sectors
– possiblymore importantin low-skill sectors,depending on asset type
– difficult to disentangle individual components
– and matters fordecisions to invest in innovation
• Digitised information more important in the skill-intensive/high-techsectors
– IT/Skill complementarity
• Intellectualproperty (own account) mainlyimportant in high-tech manufacturing
• Heterogeneity in links to productivity(across sectors/types of firm)
• Complexlinkages
