The Productivity Paradox: Policy Lessons from MICROPROD

Core Content

The productivity paradox refers to the phenomenon where, despite significant technological progress, total factor productivity (TFP) growth in Europe has been declining for several decades. This trend has raised critical questions about the underlying causes and consequences of the slowdown, especially in the context of an aging population and the challenges posed by the fourth industrial revolution.

Main Views

1. Productivity Slowdown and Its Drivers

• TFP growth in the euro area has fallen from around 5% per year in the 1950s to less than 0.5% in recent years.
• The slowdown is attributed to a combination of global factors (e.g., secular stagnation, low interest rates) and structural issues within Europe (e.g., digitalisation, globalisation, and concentration in certain firms).
• Low interest rates have contributed to the persistence of zombie firms and reduced the pace of creative destruction, which is crucial for productivity growth.

2. Intangible Capital and Productivity

• Intangible capital (e.g., software, R&D, organisational capital) plays a key role in firm-level productivity, but its aggregate impact is less visible.
• Investment in intangible capital is concentrated among a few firms, leading to uneven productivity gains.
• Financial capability is a key determinant of intangible investment, with more access to finance leading to higher productivity and mark-ups.
• Intangible capital includes human capital and organisational structures, and worker participation in decision-making (e.g., through work councils) is linked to better productivity, wages, and profits.

3. Globalisation and Global Value Chains (GVCs)

• Globalisation and free trade generally increase efficiency and productivity, but the type and origin of imports matter.
• Imports from low-income countries (e.g., China) tend to harm productivity and employment, while imports from high-income countries (e.g., the US) can stimulate R&D and productivity.
• Integration into GVCs can drive innovation, especially when buyers provide technical advice and knowledge transfers to suppliers.
• Sectoral differences and country development levels affect how firms respond to globalisation, with labour-intensive sectors being more vulnerable to negative impacts.

4. Finance and Resource Allocation

• Financial constraints significantly influence investment in intangible capital and thus productivity.
• Unconventional monetary policies (e.g., asset purchases) have had mixed effects, with some firms experiencing higher investment and productivity but lower employment growth.
• Credit allocation efficiency varies across European countries, with Germany and France outperforming Italy.
• A bank-based financial system hinders innovation in high-tech industries, highlighting the need for a more diversified financial system.

5. Social Consequences of Productivity Shocks

• Globalisation and automation can lead to asymmetric productivity gains, with some firms benefiting significantly while others face compressed margins.
• Import shocks increase income risk for workers, while export shocks reduce it. Diversified regions may thus offer better income protection.
• Technological change can exacerbate inequality, as innovation tends to be skilled-biased, potentially increasing worker inequality.
• Active labour market policies (e.g., retraining, promoting mobility) are essential to help workers adapt to new economic conditions.

Key Policy Implications

• Stimulate intangible investment: Policies should support R&D, innovation, and training, especially for SMEs, to enhance productivity.
• Deepen the single market: A stronger digital single market and capital markets union are needed to foster innovation and support high-tech industries.
• Reform competition policy: Addressing market concentration and monopoly power is crucial to ensure fair competition and prevent the negative feedback loop that stifles productivity.
• Improve financial systems: Encourage venture capital and alternative financing to support innovation and reduce reliance on bank lending.
• Enhance education and retraining: Policies should focus on upskilling workers to adapt to changes in the economy, especially in the context of digitalisation and globalisation.

Conclusion

The MICROPROD project provides a comprehensive analysis of the drivers and consequences of productivity slowdown in Europe. It highlights the importance of microeconomic mechanisms in understanding broader productivity trends and offers policy recommendations to address structural issues. The impact of the COVID-19 crisis has further complicated the picture, emphasizing the need for flexible and adaptive policies to support sustainable growth and equitable distribution of productivity gains.
