  • Reassessing EU Comparative Advantage: The Role of Technology Filippo di Mauro, Marco Matani, Gianmarco Ottaviano —
    Based on a sufficient statistics approach, we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data requirements, but still comprehensive in terms of information. The lack of systematic cross-industry correlation between export specialization and technological advantage suggests that standard measures of revealed comparative advantage only imperfectly capture a country’s technological prowess due to the concurrent influences of factor prices, market size, markups, firm selection and market share reallocation. These findings offer policy insights relevant to the EU’s external competitiveness debate, echoing several recommendations from the Draghi report. Achieving export specialization in key sectors requires more than just technological superiority.
  • Industrial Policy: New Evidence for the United Kingdom CMA Microeconomics Unit —
  • Danish productivity and competitiveness in a Globalised World Andreas Kuchler, Morten Spange, Mathias Busk Tjørnum, Thomas Rasmusen Damsgaard Tørsløv, Robert Wederkinck —
    Danish companies participate in the international division of labour with significant production abroad under Danish ownership, along with products being produced by foreign subsidiaries. There are indications that these activities are largely made possible by the position of strength of the Danish companies and that part of the profits from foreign activities cover the cost of employees and intellectual property rights in Denmark. Overall, there are indications of good productivity and competitiveness in manufacturing, but these trends are best illustrated at industry level and there are industries where things look weaker.

  • European Firm Concentration and Aggregate Productivity Marc Melitz, Filippo di Mauro, Tommaso Bighelli, Matthias Mertens —
    This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity toward large and concentrated industries. Over the same period, productivity gains from an increasing allocative efficiency of the European market accounted for 50% of European productivity growth while markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.
  • Inward Foreign Direct Investment, Superstar Firms and Wage Inequality Between Firms: Evidence from European Regions Juan Duran Vanegas, Iulia Siedschlag —
    Theoretical models and international evidence have established that foreign direct investment is associated with new technologies, productivity gains, higher wages, and wage inequality in the host countries. … We find that foreign direct investment, particularly international superstar firms, contributed to increased wage inequality between firms across European regions.
  • Declining Business Dynamism in Europe: The Role of Shocks, Market Power, and Technology Matthias Mertens, Filippo Biondi, Sergio Inferrera, Javier Miranda —
    We study the changing patterns of business dynamism in Europe after 2000 using novel micro-aggregated data for 19 countries… We derive a firm-level framework that relates changes in firms’ productivity, market power, and technology to job reallocation and firms’ responsiveness.
  • Labor Market Power and Between-Firm Wage (In)Equality Matthias Mertens — International Journal of Industrial Organization, 91 (Dec 2023), 103005
    I study how labor market power affects firm wage differences using German manufacturing sector firm-level data (1995–2016)… Using micro-aggregated data covering most economic sectors, I validate key results for multiple European countries.
  • Do Larger Firms Have Higher Markups? Matthias Mertens, Bernardo Mottironi — IWH-CompNet Discussion Papers No. 1/2023
    Several models posit a positive cross-sectional correlation between markups and firm size… We discuss implications and highlight studying input and output market power within an integrated framework as an important next step.
  • Monetary policy and local industry structure Alexander Popov, Lea Steininger — ECB Working Paper Series No. 2778 / Feb 2023
    We study how monetary policy affects local market competition in the euro area… The underlying mechanism is a decline (increase) in short-term debt and investment by smaller and medium-size firms relative to large firms following tightening (easing).
  • Does skill shortage pay off for nursing staff in Germany? Wage premiums for hiring problems, industrial relations, and profitability Arnd Kölling — HWR Berlin School of Economics
    This study investigates the impact of hiring problems, industrial relations, and profitability on wage premia for nursing staff in Germany… Overall, pay increases for nurses in firms with staffing problems; nevertheless, this does not apply to all skilled workers.

  • Synergies and gaps between farm and non-farm micro-level data for sustainable rural development Amr Khafagy, Janet Dwyer — University of Gloucestershire
    The article discusses the importance of high-quality microdata… However, social and environmental indicators are under-represented in both datasets, limiting the ability to understand drivers of performance in the rural economy.
  • Productivity and Business Dynamism in Japan — Comparison with the EU Countries Using Firm-level Data (Japanese) Daisuke Miyakawa, Miho Takizawa — RIETI
    We measure productivity and determinants of business dynamism for Japanese firms and compare with EU countries (CompNet 8th Vintage)… productivity growth in Japan has stagnated in the 2010s while allocative efficiency deteriorated.
  • Corporate economic profits in the euro area: The relevance of cost competitive advantage Javier Vallés, Vicente Salas Fumás, Lucio San Juan — International Review of Economics & Finance
    We estimate aggregate and industry cost and profit shares for France, Germany, Italy and Spain (1995–2018)… In Germany, rising profits are better explained by cost competitive advantage rather than increasing market power.
  • The Geography of the Sharing Economy in Europe Camilla Lenzia, Elisa Panzera — Romanian Journal of Regional Science
    The sharing economy develops unevenly across EU regions… results warn against potential detrimental effects for wage inequalities.
  • Increase in Turbulence and Market Power Agnieszka Markiewicz, Riccardo Silvestrini — Erasmus University Rotterdam & Tinbergen Institute
    A sector-specific increase in turbulence accelerates turnover of leaders and mobility across the productivity distribution, reallocating shares toward most productive firms and driving higher markups; the model explains 35–57% of observed markup increases.
  • Globalization in Europe: Consequences for the Business Environment and Future Patterns in Light of Covid-19 Sergio Inferrera — in: Economic Challenges for Europe After the Pandemic
    Involvement in international supply chains is positively related to sector concentration and aggregate productivity, driven by top firms; real-time trade data suggest re-absorption of the Covid shock in several European economies.
  • The Political Economy of the EU Approach to the Rohingya Crisis in Myanmar Arlo Poletti, Daniela Sicurelli — Politics and Governance
    We provide a political-economy explanation for the EU’s 2018 stance prioritizing dialogue over trade preference withdrawal, highlighting pressures from EU firms to avoid GVC disruptions vis-à-vis Myanmar.
  • Estimating market power for the European manufacturing industry between 2000 and 2014 Adrián Rodríguez del Valle, Esteban Fernández-Vázquez — Empirica
    Using sectoral input–output tables and an entropy-based method, we document heterogeneous evolution of market power across 28 countries and 14 manufacturing sectors; globalization and value-chain positioning reduce markups.
  • Labor Share, Industry Concentration and Energy Prices Çürük Malik, Rik Rozendaal — Tilburg University
    Using data from 15 EU countries and 56 sectors (2000–2016), higher energy prices reduce the labor share; we find no robust evidence that energy prices affect industry concentration or markups in the short run.
  • The diffusion of technological progress in ICT Elstner, Grimme, Kecht, Lehmann — European Economic Review, 149:104277 —
    Since the mid-2000s there have been positive, persistent technology spillovers to sectors intensively using ICT; neglecting leasing activity overestimates TFP responses in most sectors.
  • Startup Types and Macroeconomic Performance in Europe Ralph De Haas, Vincent Sterk, Neeltje Van Horen — CEPR
    Using 1.3M startups in ten countries, we identify five startup types… Policies that shift composition toward high-performance types can yield sizable gains in employment and productivity.
  • Covid-19 pandemic, state aid and firm productivity Tommaso Bighelli, Tibor Lalinsky, Juuso Vanhala — Bank of Finland
    Across five EU countries, the pandemic led to a short-term productivity decline driven mainly by within-firm dynamics; subsidies were distributed relatively efficiently but had limited aggregate productivity effects.

  • Market Power, Productivity and Sectoral Labour Shares in Europe Martina Lawless, Luke Rehill — Open Economies Review
    We show the labour share varies considerably across countries and sectors… globalisation and the rise of “superstar firms” relate negatively to the labour share, more strongly within sectors than between sectors.
  • How European Markets Became Free: A Study of Institutional Drift Germán Gutiérrez, Thomas Philippon — NBER Working Paper No. 24700
    We model why a single market promotes a supranational regulator enforcing competition beyond individual-country preferences and confirm predictions with evidence on EU institutions’ independence and enforcement strength.
  • Regional economic impact of Covid-19: the role of sectoral structure and trade linkages Philipp Meinen, Roberta Serafini, Ottavia Papagalli — ECB Working Paper 2528 / Feb 2021
    A region’s economic structure and trade relations, not only infection spread, explain the heterogeneity of labour-market impacts; EU supply-chain integration creates vulnerabilities to disruptions.

  • EIB Group Survey on Investment and Investment Finance: A technical note on data quality Brutscher, Coali, Delanote, Harasztosi — EIB Working Papers 2020/08
    The ORBIS sampling frame captures the target population well; benchmarking shows little selection bias and EIBIS portrays cross-country differences and dynamics satisfactorily relative to SBS and CompNet.
  • What drives export market shares? It depends! An empirical analysis using Bayesian model averaging Benkovskis, Bluhm, Bobeica, Osbat, Zeugner — Empirical Economics (2020) 59: 817–869
    Export market share growth links to different factors across old vs new EU member states; competitive pressure from China is key for both; price competitiveness plays a limited role overall.
  • Rising Concentration and Wage Inequality Guido Matias Cortes, Jeanne Tschopp — Working Paper, Jan 2020
    Using industry data from 14 European countries (1999–2016), we find a positive, statistically significant correlation between market concentration and between-firm wage dispersion.
  • Trade, Productivity and (Mis)allocation Berthou, Chung, Manova, Sandoz Dit Bragard — CEP Discussion Paper No. 1668, Jan 2020
    Export and import expansion both generate large aggregate productivity gains via firm-level reallocations; institutional quality amplifies gains from import competition and dampens those from export access.

  • Cyclical and structural variation in resource allocation: evidence for Europe Bartelsman, Lopez-Garcia, Presidente — ECB Working Paper 2210, Nov 2018
    Using ECB CompNet data, we show reallocation toward more productive firms varies across countries and time; the silver-lining effect in downturns did not appear during the Great Recession.
  • Structural policies in the euro area Masuch, Anderton, Setzer, Benalal (eds.) — ECB Occasional Paper 210, Jun 2018
    Structural policies—labour, product, and financial market regulations plus governance and institutions—can yield substantial gains in income and employment and support social fairness; synergies between growth and inclusiveness are highlighted.
