Use of e-commerce data for economic analysis • ICT usage by enterprises • Relation of e-commerce with – Competition – Innovation – Productivity • Need firm-level analysis – It is (too) often forgotten that the micro-data underlying national statistics is a valuable product!
E-commerce and competition • Background – Consequences of online trading: • Lower search cost • Lower transaction cost • Markets become more transparant – E. g. Brynjolfsson and Smith (2000, Management Science): “Frictionless markets” • Increases (price) competition • Motivates firms to operate cost efficiently

E-commerce and competition Markups lower in manufacturing relative to services, which indicates stronger competition in manufacturing Source: CBS (2015), ICT and Economic Growth.
E-commerce and competition Increases in e-sales and ecommerce in general have significantly lowered markups, in all sectors Source: CBS (2015), ICT and Economic Growth.
E-commerce and competition • Background – Innovation is a driver of economic growth – Crépon-Duguet-Mairesse (CDM): • Firms invest in R&D (innovation input) • … this leads to knowledge generation (product innovation) • … which ultimately results in increased business performance (productivity) – Variations: • Griffith et al. (2004): product and process innovation • Brynjolfsson et al: ICT investments and complementary organizational changes

E-commerce, innovation and productivity • In terms of productivity gains: e-commerce and process innovation complement each other – That is: combination of both leads greater increase in productivity than the sum of their effects in isolation • Same for e-commerce and organizational innovation • Combination of product innovation with e-commerce does not have any excess productivity gains in manufacturing, and leads to lower gains in services (substitutes) Manufacturing product process organizational e-commerce n. s. COMP Services product process organizational e-commerce SUBS COMP
Cross-country analysis using micro-data • Background: – Comparability of micro-level studies – What is the impact of institutional setting, regulation, and policy? – Lack of available cross-country micro-data

Cross-country analysis using micro-data • ESSNet projects on data linking and ICT impact (ICT Impact, ESSLimit, ESSLait) • 14 participating NSOs • ‘Micro-moments database’ – Indicators based on ‘micro-aggregated’ data – … from linked EC, IS, PS, trade databases – … going beyond usual breakdowns of aggregate data • Moreover: harmonized ‘distributed’ microdatasets at various NSOs allow for remote execution type of empirical analysis

Cross-country analysis using micro-data • Examples: – Dispersion of productivity growth and ICT • Productivity growth by country × time × industry • … and ICT vs non-ICT intensive firms – Resource allocation: • Employment growth by by country × time × industry • … and by quartile of the firm-level productivity growth distribution

Cross-country analysis using micro-data
Selected data issues International comparability is in general hampered by differences in • surveys between EU and non-EU and/or non-OECD countries • frequency of the survey • voluntary or compulsory nature of the survey • coverage of subsamples, especially in small countries • reference and recall periods • treatment of outliers and multinationals • ranges recorded in surveys • sectoral coverage • …
Data issues Micro-data analysis benefits from • Increased coverage of firms over time • Coordination of sampling design between surveys (e. g. innovation and ICT) • Stability of definitions and concepts over time • Harmonization of definition and concepts across surveys • Increased international harmonization allows the analysis of micro-data in a cross-country setting
