Intangible Assets and Their Contribution to Growth in Germany –
Main Findings From a Macro-, Sector- and Micro-Level Perspective

Main Tasks of ZEW Within COINVEST
Collecting time series of intangible capital and exploring its contribu-tion to economic growth in Germany using growth accounting methods at the macro level● Focus on sensitivity analysis using alternative data sources
Collecting time series of intangible capital and performing growth accounting at the sector level
Assessing the impact of various (not all) types of intangible capital on productivity using German firm-level data

Intangible Assets: Benchmark Estimates
Computerized information ● Computer software: EU KLEMS
● Computerized databases: EU KLEMS (NACE K724)
Innovative property ● R&D, including social sciences and humanities: GERD (Eurostat)
● Mineral exploration: German national accounts
● Copyright and license costs (Creative Industries): German national accounts
● New product development costs in the financial industry: STAN (OECD)
● New architectural and engineering designs: EU KLEMS
Economic competencies ● Brand equity: EU KLEMS, SBS (Eurostat), World Magazine Trends,
● Firm-specific human capital: LCS 2004, CVTS 2005, EU KLEMS
● Organizational structure: Annual Survey of the European Management Consultancy Market, Structure of Earning Survey 2002 (Eurostat)
Intangible Assets: Sensitivity Analysis
Computerized information ● Computer software: EU KLEMS Nov2009 Release
● Organizational structure: Turnover tax statistics (74.14.1), Structure of earnings survey, EU KLEMS Nov2009
Advantage of Alternative Data Sources
Turnover Tax Statistics● Census from the data of the tax authorities that covers nearly all economic
sectors with high quality. It is not based on a sample survey such as the structural business statistics.
● Annual data since 1996 (before that on a biennial basis).
● Unlike SBS no structural break in the year 2000.
● Disaggregated data e.g. on market research (74.13.1) and public opinion polling (74.13.2) available.
● Used for: Computerized databases, mineral exploration, copyright and license costs, new architectural and engineering designs, brand equity, purchased organizational structure.
Advantage of Alternative Data Sources
MIP Mannheim Innovation Panel ● Part of Community Innovation Surveys
● Representative survey
● Annual survey in Germany (EU: 4/2 years), started in 1993
● Extrapolation of figures, based on appr. 5000-6000 firms per year
● Training
• Allows industry break-down for vocational training
• Only direct training costs. Indirect costs are estimated using the proportion of direct to indirect costs provided by IW (av. every 3 years)
● Question on innovation expenditure in the financial industry
● Covers internal and external marketing expenditures beyond advertising
● Used for: Brand equity, new product development costs in the financial industry, and firm-specific human capital
Advantage of Alternative Data Sources IW (Institute of the German Economy)
● Survey data (every three years)
● Direct and indirect training costs.
● Indirect costs: number of training hours * average wage
● Proportion of direct costs to total costs: on average 35%
● Indirect costs used for: Firm-specific human capital.
ZAW (Central Association of the German Advertising Industry)● Publicly available time series data since the mid eighties.
● Broad coverage of all advertising activities and media channels.
● Allows a distinction between net advertising expenditure (media revenues) and gross advertising expenditures (also exp. for the design/production of adv. content and material).
● Unlike SBS no structural break in the year 2000.

Motivation
At the micro level:
● Much evidence on productivity enhancing effects of R&D
● But only scarce evidence on the effect of other types of intangibles
investments at the firm level
Research question: Do all types of investments in intangible assets
enhance productivity at the firm-level?
Analysis based on panel data (MIP) for German companies from 2006-
2008 (5117 firms, 7552 observations).
Estimation Approach
Cobb-Douglas production function
● With Q: output, L: labour, K: physical capital, M: material, λ: exogenous technological change, u: error term
● RD: R&D capital, NI: non-R&D related innovation capital, TR: human capital, MKT: marketing
As log specification:
Estimation Methods: Pooled OLS, FE (fixed effects), FD (first difference estimation, i.e productivity growth)

Knowledge-related Intangible Input Factors R&D:
● log (R&D expenditure / employee)
Non-R&D related innovation: ● log (expenses for external knowledge, design, market introduction, training and
product preparation related to innovation / employee)
Marketing: ● log (marketing expenditure / employee)● Note: to avoid double accounting we correct for market expenditure for innovation
projects (based on industry average in prior wave)
Training: ● log (training / employee)● Note: to avoid double accounting we correct for training expenditure for innovation
projects (based on industry average in prior wave)
Organisational innovation: ● 4 dummies for whether the firm has introduced new practices, workplace
organisation, knowledge management and external relationships
Additional Explanatory Variables
Traditional input factors:● Labour : log (# employees)
Note: to avoid double counting we correct the total number of employees for R&D employees
● Physical capital: log (tangible assets / employee)Note: tangible assets are direct information from the survey
● Material: log (material expenses / employees)
Control variables:● East Germany: dummy whether firm is located in East Germany● Export intensity: exports / sales● Group: company is part of a group (0/1)● Time dummies● Industry dummies
Main Findings From Micro Work
We confirm strong positive productivity effects for R&D, marketing and training.
Effects of marketing are highest, even higher than those of R&D (in the short term).
Only weak evidence for positive productivity effects of non-R&D related innovation assets like design, licenses and product preparation.
Mixed productivity effects of firms increasing their organizational capital by introducing organisational innovations: ● positive effect for business practices
● but not for workplace organisation
