1 InnovaTion, InvesTment and ImiTation: How Information and Communication Technology Affected European Productivity Performance Bart Los and Marcel Timmer, University of Groningen (Faculty of Economics, Groningen Growth and Development Centre) This project is funded by the European Commission, Research Directorate General as part of the 6th Framework Programme, Priority 8, "Policy Support and Anticipating Scientific and Technological Needs".
4 ICT as a GPT ICT as GPT (see David, AER 1990; Brynjolfsson & Hitt, JEPersp 2000; Hall & Trajtenberg 2004 NBER) Europe has exhausted imitation in old technologies, and is lagging in application of new ICT-based innovations (Aghion and Howitt 2006, JEEA). Divergence is possible. Degree to which imitation can lead to productivity gains depends on technology operated (appropriate technology, Basu & Weil, QJE, 1998 ) Traditional growth accounting findings : Total Factor Productivity growth in market services in US, but not in Europe ( see Jorgenson, Ho and Stiroh 2005; Triplett and Bosworth 2004; Inklaar, OMahony and Timmer, RIW, 2003; Timmer & Van Ark, OxEP 2005.)
5 This paper TFP should be divided into pure technological change (innovation) and efficiency changes (imitation) through estimation of global production frontier. (see Los & Timmer, JDevE 2005, Timmer and Los, JPA 2005) ICT capital is a critical input Questions How many years are European countries lagging behind in ICT? How efficient are European countries in using old-vintage ICT? Does this differ for various sectors? How much of European growth is due to innovation and how much due to imitation?
6 Falling behind, catching up or leapfrogging? ICT/hour GDP/ hour GE00 US00 US04 GE04?
7 Frontier Estimation Data Envelopment Analysis on 1 output (GDP) and 3 inputs (labour, IT and non-IT), assuming CRS (Färe et all, 1994, AER) Non-parametric approach with very few restrictions on production technology Advantage is flexible functional form, which allows for localized technological change DEA with intertemporal dataset, to avoid technological regress. –Frontier for year y based on all observations from 1980 up to y –First frontier for 1990.
12 Data -Fourteen countries: EU-15 (minus Luxembourg and Ireland), and U.S. -GDP (at PPP), total hours worked and capital stocks for 1980-2004 -Harmonised Capital stock estimates for six assets, using Perpetual Inventory Method, aggregated into two groups: Non-IT and IT capital Non-IT: machinery, transport equipment and non-residential buildings; IT: office and computing equipment, communication equipment and software. -All data from The Conference Board and Groningen Growth and Development Centre, Total Economy Database, May 2006, (www.ggdc.net) (Updated from Timmer & Van Ark, OxEP, 2005)www.ggdc.net
23 Main findings and road ahead Global production frontier is driven by investment in ICT capital goods European countries lag US in application of ICT technology (4 to 16 years) Some countries are succesful imitators (FR, UK, DK), but others face divergence (IT, PT, ES) Different pattern at industry level: innovation in manufacturing in some countries
24 Main findings and road ahead Industry-level analysis, in particular services: EUKLEMS data project Explanation of divergence in terms of Imitation (inefficiency model) including regulation and skilled labour supply as determinants
