1. What should be done about Google’s quasi-monopoly in search? Mandatory data sharing versus AI-driven technological competition

Working Paper
Institution:

Abstract:
The first part of this paper focuses on competition between search engines that match user queries with webpages. User welfare, as measured by click-through rates on top-ranked pages, increases when network effects attract more users and generate economies of scale in data aggregation. However, network effects trigger welfare concerns when a search engine reaches a dominant market position. The EU Digital Markets Act (DMA) imposes asymmetric data sharing obligations on very large search engines to facilitate competition from smaller competitors. We conclude from the available empirical literature on search-engine efficiency that asymmetric data sharing may increase competition but may also reduce scale and user welfare, depending on the slope of the search-data learning curve. We propose policy recommendations to reduce tension between competition and welfare, including (a) symmetric data sharing between all search engines irrespective of size, and (b) facilitate user real-time search history and profile-data portability to competing search engines. The second part of the paper focuses on the impact of recent generative AI models, such as Large Language Models (LLMs), chatbots and answer engines, on competition in search markets. LLMs are pre-trained on very large text datasets, prior to usage. They do not depend on user-driven network effects. That avoids winner-takes-all markets. However, high fixed algorithmic learning costs and input markets bottlenecks (webpage indexes, copyright-protected data and hyperscale cloud infrastructure) make entry more difficult. LLMs produce semantic responses (rather than web pages) in response to a query. That reduces cognitive processing costs for users but may also increase ex-post uncertainty about the quality of the output. User responses to this trade-off will determine the degree of substitution or complementarity between search and chatbots. We conclude that, under certain conditions, a competitive chatbot markets could crowd out a monopolistic search engine market and may make DMA-style regulatory intervention in search engines redundant.

Working Paper

Abstract:
While the Russian invasion of Ukraine has created a new momentum for EU defence integration, the political feasibility of such integration remains disputed, as it may entail both additional financial costs and a loss of sovereignty. Furthermore, design of defence integration is inherently multidimensional, differing in terms of scope and level, governance and sources of financing, among other dimensions. To determine the extent of public support for European security cooperation, we conducted the first conjoint experiment ever fielded on public support for alternative defence union designs. We carried out a pre-registered, randomised conjoint experiment on a highly representative sample of the French, German, Italian, Dutch and Spanish populations in November 2022. This multidimensional conjoint experiment allows us to determine the causal link between policy features of potential defence pacts, and public support or opposition to such policy. Our results show that policy packages receiving the most support require joint EU-level governance, joint purchases of military equipment through joint procurement, and repurposing of existing national expenditure as the preferred form of financing. All in all, our results show not only that there is considerable cross-border support for defence integration in Western Europe, but also that citizens in different Western European countries have generally aligned preferences regarding the actual design of such policy, indicating that a compromise policy is feasible and publicly supported. Furthermore, our results support ongoing research on the nature of European solidarity at times of crisis, suggesting that European citizens are willing to support the creation of joint institutions and policies to face issues of common concern, and therefore indicating that major crises open important windows of opportunity to re-shape EU-level policies and institutions.

Abstract:
As the Chinese economy continues to decelerate, the central government is investing heavily in innovation, doubling down on research and development (R&D) spending and STEM-oriented human capital. In this paper, we assess China’s progress so far, looking at the inputs to innovation (R&D and human capital) as well as intermediate targets, such as scientific research and patents. We then evaluate how China has fared with respect to the ultimate goal of commercialising this progress, by looking at the value-added of Chinese exports and the overall productivity of the economy. We identify three potential bottlenecks that might be hindering the translation of China’s innovation efforts into productivity growth.

4. Antitrust issues raised by answer engines

Author:
Christophe Carugati
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Rapid development of generative artificial intelligence chatbots like ChatGPT is leading search engine providers to move from search to answer engines. Unlike search engines, which provide search results in the form of blue links to content creators, answer engines generate personalised answers through a conversation with end users. This revolution impacts the internet ecosystem of content creators and the digital advertising market. This paper outlines some early antitrust issues related to answer engines, from the transition from search to answer engines (sections 2 and 3) and the response competition authorities should adopt (section 4). It finds that search and answer engines complement and compete with each other. While the answer-engine market is still at an early stage of development, it already raises some competition issues in relation to data scraping, vertical integration and unfair terms and conditions. Intervention by competition authorities is more likely than not to prevent market power in this new market. In this regard, competition authorities should act to preserve dynamic competition and minimise adverse effects on content creators. Finally, the paper concludes with several research questions for future research (section 5).

5. Global trends in countries‘ perceptions of the Belt and Road Initiative

Working Paper
Institution:

Abstract:
Drawing on global media reports, we conduct a sentiment analysis of the image of China’s Belt and Road Initiative (BRI) and the evolution of its image over time. Our main finding is that perceptions of the initiative deteriorated significantly in many geographies from 2017 to 2022. The notable exception is in sub-Saharan Africa where the BRI’s image remains positive, even if slightly less so than in the past. This is notwithstanding increases in debt levels with China, much of which now face potential restructuring. Furthermore, we find significant inter- and intra-regional differences in the average sentiment towards China’s landmark project, as well as a much worse image of the initiative in countries which, until today, are not part of the BRI. Finally, we focus on the European Union, Africa and China’s immediate neighbourhood to better understand the complexities behind the perceived benefits and challenges associated with China’s Belt and Road Initiative.

6. Pro- and anti-competitive provisions in the proposed European Union Data Act

Author:
Bertin Martens
Publication Date:
01-2023
Content Type:
Working Paper
Institution:
Bruegel
Abstract:
The proposed European Union Data Act gives users access and portability rights to the data generated by their use of tangible digital products and devices. This pro-competitive measure weakens the de-facto monopolistic control product manufacturers have over product data. However, the Data Act would also grant manufacturers a de-jure right to monopolistic pricing of data transfers to third-party service providers, restoring their control over data markets. Other anti-competitive provisions include restrictions on the use of data for competition purposes and a prohibition on transfering data to platforms identified as gatekeepers under the EU Digital Markets Act. Unnecessarily fuzzy definitions of products and data that fall under the Data Act would create uncertainty in implementation and incoherence with other EU data regulations. The Data Act should be simplified by dropping anti-competitive provisions and granting users and third-parties selected by users free access to all data generated by the use of a product or a service. This would increase competition in data-driven services and prevent users paying twice for their data. It would not disincentivise producers from investing in data-driven products and services. A further step could be the creation of a level playing field between producers and users in data-access rights. This can be achieved by introducing the principle of mutual exhaustion of data rights at point of sale. This would put all data co-generating parties in a position to generate economies of scale and scope in data aggregation, or data-driven externalities, to maximise innovation.

7. The EU can manage without Russian liquified natural gas

Content Type:
Policy Brief
Institution:

Abstract:
The European Union has committed to eliminate all Russian fossil-fuel imports by 2027. Progress has been made, with sanctions on oil and coal already introduced. The glaring exception is natural gas, on which the EU has so far refrained from imposing limitations, owing to greater dependence on Russia. Nevertheless, pipeline gas imports have fallen by four-fifths following Russia’s weaponisation of gas supplies. However, Russia’s exports of liquified natural gas (LNG) to the EU have increased since the invasion of Ukraine. The EU needs a coherent strategy for these LNG imports. Our analysis shows that the EU can manage without Russian LNG. Anticipated impacts are not comparable to those felt in 2022 as Russian pipeline gas dried up. The regional impact would be most significant for the Iberian Peninsula, which has the highest share of Russian LNG in total gas supply. Meanwhile, the global LNG market is tight, and we anticipate that Russia would find new buyers for cargos that no longer enter Europe. We discuss the options available to the EU. Wait-and-see implies delaying any action until 2027, while soft sanctions would discourage additional purchases but not break long-term contracts. We argue instead for an EU embargo on Russian LNG, to reduce exposure to an unreliable and adversarial entity, and to limit the extent to which EU consumers fund the Russian state. The embargo may be designed to allow purchases only if they are coordinated via the EU’s Energy Platform, with limited volumes and below market prices. This could be accompanied by the implementation of a price cap on Russian LNG cargos that use EU or G7 trans-shipment, insurance or shipping services.

8. Rebooting the European Union’s Net Zero Industry Act

Publication Date:

Content Type:
Working Paper
Institution:

Abstract:
In March 2023, the European Commission published a legislative proposal for an EU response to the US Inflation Reduction Act: the Net Zero Industry Act (NZIA). It is an unconvincing policy proposal, both for what is in it and for what is not in it. The proposal has five problematic aspects. First, it takes a top-down approach, in which specific technologies are selected for preferential treatment. Preferable would be a technology-neutral approach open to all current and future technologies that help tackle the net-zero challenge. Second, its blanket 40 percent self-sufficiency benchmark for EU domestic cleantech manufacturing by 2030 sends a protectionist signal, is poorly defined and does not reflect the differences in EU capacity in the cleantech sector. Third, it relies on the acceleration of permitting procedures as the main policy instrument, although this is not the main obstacle to cleantech investment in the EU. Fourth, it proposes more strategic use of public procurement. While this is an objective to be supported, the specific proposals are likely to be ineffective because of the way they are designed. Fifth and not least, the NZIA would lack a governance structure that would ensure effective implementation. In addition, the NZIA does not tackle three critical issues. It does not address investment obstacles related to failures of the single market. It does not tackle the coordination problem at the core of developing an EU green industrial policy. Finally, it does not develop an EU-level funding strategy, but rather relies on state aid, with the related risk of fragmentation. The European Parliament and EU countries in the Council of the EU should reboot the proposal and refocus its objectives, sharpening its limited instruments, improving its governance, and adding financial incentives to ensure implementation. In parallel, the EU should develop a broader green industrial policy strategy that leverages the single market in a credible manner, building a solid new governance framework and a new EU-level funding approach.

9. Can Chinese growth defy gravity?

Author:
Alicia Garcia-Herrero
Publication Date:

Content Type:
Policy Brief
Institution:
Bruegel
Abstract:
Chinese growth, astounding since the beginning of the reform era, has slowed in the last decade. We offer a baseline estimate (based on the current trend) of China’s medium-term growth rate, which we project to fall to 2.4 percent by 2035. Several factors create uncertainty around this baseline. China’s rapid aging is already incorporated into our long-term growth scenario, but its impact on growth will depend on how China’s remaining urbanisation process spreads over time, how the shrinking labour supply affects labour productivity and whether the decline in total factor productivity growth, reflecting the lack of reform during the last decade and possibly the rising role of the state, can be reversed. Investment in China, for decades the largest factor in China’s growth, is expected to contribute less to growth given the increasingly low return on assets, particularly on state-led investment. The rapid piling up of public debt is also becoming a heavy burden for the Chinese economy. Finally, the COVID-19 pandemic may have left significant scarring effects, such as structurally high youth unemployment and low investment confidence. On the upside for China, the rise in human capital and research and development expenditure may support innovation and growth, but the magnitude of this effect is uncertain, because it is unclear if higher innovation will translate into higher total factor productivity, and because of the United States’s push to contain China technologically.

10. The rising cost of European Union borrowing and what to do about it

Author:
Gregory Claeys and Conor McCaffrey
Publication Date:
05-2023
Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Debt issuance by the European Commission on behalf of the European Union has increased massively. Of the approximately €400 billion in outstanding EU debt as of May 2023, 85 percent has arisen from borrowing since 2020. Large-scale borrowing is expected to continue until 2026 to fund the remainder of NextGenerationEU, and concessional loans to support Ukraine. When these programmes were launched, interest rates were at historic lows – even negative for maturities below 10 years. However, interest rates rose sharply in 2022. Beyond the widespread rise in euro-denominated interest rates due to monetary tightening by the European Central Bank in response to the inflation surge, the EU has also faced a widening of the spread between its yields and those of major European issuers, including France and Germany. This widening is driven by a combination of market features, circumstantial factors and institutional features. The EU cannot affect the overall cyclical movement of interest rates and will have to learn to live with it, like sovereigns do. However, the European Commission should continue to try to narrow the spread with major European sovereigns by further developing the relevant market infrastructure and improving its issuance strategy. The Commission will not be able to do this alone. Institutional developments, including progress on the development of new own resources and a long-term substantial presence in the bond market, will be necessary to fully reap the benefits of EU borrowing. A large share of EU borrowing (around €421 billion in total by the end of 2026, in current prices) is intended to finance unprecedented non-repayable support: Recovery and Resilience Fund grants and additional funding for existing EU programmes under the EU budget. The interest costs associated with this part of the debt lie with the EU budget. Our estimates suggest that, because of the high current and expected levels of interest rates, this cost could be twice as high as what was initially estimated at the start of the EU’s 2021-27 budget cycle. As a result, because interest costs for the borrowing of the non-repayable support are accounted for under the EU budget’s ‘expenditure ceiling’, this will exert further pressure on the funding of important EU programmes, which are already affected by inflation. The EU should thus quickly review how interest costs are accounted for in its budget and financial framework.

11. Adjusting to the energy shock: the right policies for European industry

Author:
Giovanni Sgaravatti, Simone Tagliapietra, and Georg Zachmann
Publication Date:
05-2023
Content Type:
Policy Brief
Institution:
Bruegel
Abstract:
In 2022, overall European Union industrial employment and output increased above 2021 levels, despite rocketing energy prices. However, output declined from energy-intensive industries including basic metals, chemicals, non-metallic minerals and paper, for which energy costs represent a much bigger share of production costs than for less energy-intensive manufacturing. Energy prices are likely to remain above historic levels for the foreseeable future. In its industrial strategy response to this context, the EU must ask first whether the energy-intensive parts of the value chain should be outsourced permanently. Conditional on the answer being no, the second question is how to reduce energy prices to ensure the competitiveness of the energy-intensive productions stages that remain in the EU. First, the EU could bridge the high energy price period with unconditional subsidies, which seems to be the preferred strategy currently. This will avoid irreversible large-scale relocation abroad but is expensive, does not help to drive down energy prices and poses risks of fragmentation within the EU. It will only succeed if internationally competitive energy supplies are made available quickly. Second, the EU could support decarbonised production processes built on large-scale deployment of domestic renewables, grid interconnectors and storage. This would accelerate the green transition and reduce clean-tech prices worldwide. However, EU taxpayers would bear the cost of new technologies, without any guarantee of solving the current cost-competitiveness issue. Third, the EU could facilitate imports of energy-intensive products, while helping EU industry move to higher value-added parts of the value chain. Subsidies could be given directly to industrial sectors that have not become structurally uncompetitive, while bringing down energy demand and thus energy prices. However, this strategy would result in temporarily higher unemployment and factory closures in energy-intensive industries, would need to accommodate concerns over excessive reliance on imports and would need to be engineered to address carbon leakage. Policymakers should implement a mix of these policies. The EU should subsidise existing energy-intensive industries only in clearly justified cases, while deciding which energy-intensive products can be left to international market forces. By choosing which decarbonisation investments should be supported in Europe, the EU can combine industrial competitiveness and environmental sustainability.

12. The longer-term fiscal challenges facing the European Union

Publication Date:
04-2023
Content Type:
Policy Brief
Institution:

Abstract:
The pandemic and subsequent price shocks triggered by Russia’s invasion of Ukraine, have increased longer-term fiscal pressures in the European Union through higher debt, higher expected real interest rates and higher public investment needs. This Policy Brief makes some simple quantitative assessments of those effects and discusses policy implications, with the following results. First, long-term increases in primary fiscal balances required to offset higher debt and higher expected real interest rates are in the range of 0.5 percent to 1.5 percent of GDP for most EU countries. However, because of pre-existing differences in fiscal space, not all countries will need to undertake that adjustment, while some countries may need to adjust by substantially more. Among the 21 EU countries for which we have data to undertake this analysis, 14 will need to adjust by more than they were planning to do by 2025. Second, the required additional fiscal adjustment looks manageable, although it is substantial in some cases. To achieve medium-term debt-reducing primary balances, several EU countries will need to raise primary balances by more than 2 percent of GDP above their 2025 target, but no country will need additional fiscal adjustment of more than 3 percent of GDP. Third, market data suggests that the future path of real interest rates is very uncertain. Compared to the period immediately preceding the pandemic, longer-term expected real interest rates have increased by about 2 percentage points but remain low on average, at about 1 percent in real terms. Future developments depend on whether the structural factors that led to low interest rates in the first place persist or unwind. While interest rates might decline again, fiscal policymakers should not make plans that assume such a decline. Fourth, public spending needs for additional defence and climate spending run well above 1 percent of GDP per year. These needs do not appear to have been incorporated into current fiscal baselines, and hence will come on top of the adjustment described above. To ensure that fiscal adjustment does not defeat its purpose by slowing growth, it is essential that it is conducted gradually. In countries that require such adjustment, it should start as soon as cyclical conditions allow.

13. The potential of sovereign sustainability-linked bonds in the drive for net-zero

Author:
Alexander Lehmann and Catarina Martins
Publication Date:
03-2023
Content Type:
Policy Brief
Institution:
Bruegel
Abstract:
European Union governments have for some years issued green bonds that raise funds for climate-related spending. These bonds have been received well in capital markets but because they promise a certain use of proceeds, they complicate budget management and may not match investors’ claims of having an impact on national climate policies. Public commitments made by major investors and asset owners suggest that limiting climate transition risks and the assessment of the alignment of sovereigns with net-zero targets will now become key determinants of portfolio allocation. Yield differentials in bond markets are already beginning to reflect transition risks that arise from the inadequate pursuit by issuers of climate targets. Unlike standard green bonds, sustainability-linked bonds (SLBs) create a link between performance (outcome) indicators and the financial terms of the bonds. SLBs have grown rapidly in importance in private markets and are now being assessed by sovereign issuers. We show that sovereign SLBs could help incentivise climate policies in EU countries, and accelerate emission reductions. They would be an effective tool for signalling commitment. A common EU framework for issuance by EU countries would enhance capital market integration and the transparency of national policies, and would limit climate transition risks in EU capital markets more broadly.

14. Phased European Union electricity market reform

Author:
Georg Zachmann and Conall Heussaff
Publication Date:
03-2023
Content Type:
Working Paper
Institution:
Bruegel
Abstract:
In an environment of record-breaking electricity prices driven by a gas supply shock and below-average electricity generation, reforming the design of the European electricity market is seen as a means to delink consumer costs from volatility in short-term power markets. Electricity markets should meet three objectives: fairness, optimal investment and optimal operation. The current market design has achieved these objectives to varying degrees. Faced with the unprecedented shock, the electricity system has operated well, but electricity markets have struggled to achieve fair outcomes and investments have not been driven by market-based cashflows. Further complicating market reform, the power system is being changed radically by decarbonisation. The electricity system is becoming more decentralised and digitalised, with an active demand side. These transformations will have consequences for the optimal electricity market design in the later stages of the energy transition. Reform proposals have focused on increasing the share of long-term contracts in the remuneration of generation technologies. Different long-term contracting regimes have structural implications for the functioning of electricity markets, especially in relation to the roles of the state and the market, and the responsibilities of national governments and European Union institutions. A phased approach should be taken to EU electricity market design reform. In the near-term, reform should seek to protect consumers and drive investment. An assessment should also be made of what market design will best meet the fairness, investment and operational objectives in a decarbonised system, and what the conceptual role of electricity markets should be during the transition. This process should start as soon as possible so well thought-through proposals are available when the next European Commission takes office.

Abstract:
The 2022 United States Inflation Reduction Act (IRA) is a significant and welcome climate law. It also includes trade-distortive subsidies, including local-content requirements prohibited under World Trade Organisation rules – the first time the US has done this and a blow to the international trading system that could trigger protectionism in other countries. The expected IRA green subsidies are of similar size to those available in the European Union, except in renewable energy production, where EU subsidies remain far larger. However, there are important qualitative differences. Some IRA subsidies discriminate against foreign producers while EU subsidies do not. IRA clean-tech subsidies are simpler and less fragmented, and they focus mainly on mass deployment of green technologies rather than innovation. The IRA will likely harm Europe through its competitiveness effect, while it will likely benefit climate transition in Europe and most of the rest of the world. However, the magnitude of both effects is very uncertain, partly because the IRA will induce substitution away from Chinese inputs. By forcing the reorganisation of supply chains, the IRA may make the EU and other economies more competitive relative to China. It may also initially slow the green transition. But in the longer run, this effect should be outweighed by the reduction in the cost of clean tech driven by the IRA. In responding to the IRA, the EU should not just seek to protect its competitiveness relative to the US but to pursue broader aims, including competitiveness in general, speedy decarbonisation and broad foreign policy and development policy goals. These aims imply that the EU should not impose local-content requirements of its own, should not loosen state-aid rules and should not mimic the IRA’s approach to manufacturing subsidies. Rather, it should focus on boosting its structural competitiveness, formulate a trade policy response that includes reform of the international subsidies regime, and develop an instrument for EU-level subsidies that focuses on early-stage development and increasing EU resilience to trade disruptions.

16. Measuring the intangible economy to address policy challenges

Author:
Marie Le Mouel
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
European economies exhibit the so-called ‘productivity puzzle, whereby investments’ in digital technologies and intangible assets have not delivered the hoped-for productivity gains. Explanations for this puzzle lie in the unequal ability of companies to make use of these technologies, and resulting patterns of market concentration, productivity divergence and dampened business dynamism. Access to firm-level data is essential to properly understand these rich dynamics. The purpose of the first work package of the MICROPROD project was to improve the firm-level data infrastructure, expand the measurement of intangible assets and enable cross-country analyses of these productivity trends. The MICROPROD researchers developed the Micro Data Infrastructure (MDI), a centralised platform that harmonises access to the firm-level data gathered by national statistical institutes. The data infrastructure developed through this work package offers valuable insights into the evolution of productivity across the European Union and into the effects of digitalisation and globalisation. It can thus generate important evidence for designing policies to support the European Commission’s policy objectives, especially for achieving the digital and green transitions. In addition, the research enabled by this data infrastructure and carried out within the context of MICROPROD can provide valuable lessons about the response of European economies to the COVID-19 pandemic and its aftermath.

17. Raising EU productivity through innovation

Author:
Reinhilde Veugelers and Frederic Warzynski
Publication Date:
06-2022
Content Type:
Working Paper
Institution:
Bruegel
Abstract:
Research and development is seen as a key contributor to growth because it generates knowledge, leading to new or improved products through product innovation, and makes firms more efficient at producing goods through process innovation. Firm level studies generally find evidence of strong positive productivity effects for firms that invest in R&D. In this context, digital systems could be an important driver of productivity growth, particularly in combination with investments in R&D. But there has been little hard evidence of a significant productivity boost from digital technologies. How the relationship between productivity growth, innovation and digital technology adoption plays out is particularly important for the European Union, where productivity growth has long been weak. Researchers from the MICROPROD project have assessed the effect of technology investment on productivity and performance. Combining recent unique firm-level data and state-of-the art research methodologies, MICROPROD research provides a better overview of which firms are most likely to adopt digital technologies and to innovate, and to turn these investments into productivity growth.

Content Type:
Policy Brief
Institution:

Abstract:
Uncertainty about the supply of Russian natural gas is causing extremely high and volatile European gas and electricity prices. European Union countries may struggle to import sufficient volumes of natural gas at reasonable prices. During the summer, the imperatives are to fill storage sites sufficiently in a coordinated manner and to organise sufficient import volumes to replace a substantial share of gas that might no longer come from Russia. Coordination is essential to ensure that disruptions during difficult winter months do not lead to a break-up of the EU internal gas market with potentially serious political repercussions. One part of the EU response is establishment of an EU Energy Platform for the purchase of gas, LNG and hydrogen. This aims to pool demand to leverage the bloc’s economic clout, international outreach to reliable partners and efficient use of existing infrastructure. EU leaders have backed the plan but it has not yet been translated into a feasible scheme. The platform should be developed into an effective emergency tool to safeguard gas supply in case Russian flows stop. We detail two complementary proposals to achieve this. First, there should be EU-wide auctioning of remuneration for filling storage sites in specific regions. Companies would remain responsible for all stages of the value chain, benefitting from remuneration and in return offering the market operator some control over how this gas is released during winter months. Second, EU demand for additional LNG quantities, and the sourcing of this on international markets, should be coordinated through a platform, creating a transparent market for these volumes. These mechanisms would resolve the prevention paradox and prevent free-riding. If EU countries buy gas jointly, they will find it much easier to let markets allocate scarce volumes across borders in case of a complete stop to Russian supplies. . This would reduce the risk of energy market fragmentation, as well as the subsequent energy security, economic and political impacts of a shock that would hit member states very differently.

19. Legal options for a green golden rule in the European Union’s fiscal framework

Author:
Zsolt Darvas
Publication Date:
07-2022
Content Type:
Policy Brief
Institution:
Bruegel
Abstract:
Achieving the European Union’s climate goals and decoupling from Russian energy will require a massive increase in green public spending, which will be difficult when EU fiscal rules requiring fiscal consolidation are reinstated. The two major proposals to address the conflicting goals of fiscal consolidation and increased green public investment needs are a possible new European climate investment fund and a green golden rule. The latter would exclude any increase in net green public investment from the fiscal indicators used to measure compliance with fiscal rules, for countries with sound public finances. An EU climate fund and a well-designed green golden rule would be equivalent in terms of project selection, implementation and control procedures. If the climate fund does not involve redistribution across member states, then the treatment of related spending and consequent borrowing in national fiscal indicators and in the EU’s fiscal framework would be the same. New regulations would be needed to set up both the climate fund and the green golden rule. Special legislation would be needed to exempt the subsequent climate expenditures from EU fiscal rules in both cases. A climate fund financed by EU borrowing with redistributive effects across countries would likely result in the exclusion of the fund’s activities from national fiscal indicators and EU fiscal rules without any legislative changes. There are question marks about the desirability and political feasibility of redistribution across the EU for climate purposes. An EU climate fund, irrespective of whether or not it involves redistribution, would mainly benefit southern and eastern EU countries. An instrument is needed to foster green public investment in western and northern EU countries as well. The green golden rule would be such an instrument. While there are some pragmatic options to mimic a green golden rule in the current EU fiscal framework, such as amending the so-called ‘investment clause’ and adjusting the medium-term objective for the structural balance, ultimately, elements of the 2011 Six-Pack legislation and the 2012 Treaty on Stability, Coordination and Governance should be revised to include a green golden rules.

Abstract:
Three quarters of the European Union’s greenhouse gas emissions stem from burning coal, oil and natural gas to produce energy services, including heating for buildings, transportation and operation of machinery. The transition to climate neutrality means these services must be provided without associated emissions. It is not possible today to determine tomorrow’s optimal clean energy system, largely because the cost, limitations and capability developments of competing technologies cannot be predicted. Energy systems with widely diverging shares of ‘green fuels’, in the form of electricity, hydrogen and synthetic hydrocarbons, remain conceivable. We find the overall cost of these systems to be of the same order of magnitude, but they involve larger investments at different stages of value chains. A large share of synthetic hydrocarbons would require more investment outside the EU, but less in domestic infrastructure and demand-side appliances, while electrification requires large investment in domestic infrastructure and appliances. Current projections show an overall cost advantage for direct electrification, but projections will evolve and critical players may push hard for alternative fuels. Policy will thus play a major role in shaping this balance. Political decisions should, first, push out carbon-emitting technology, primarily through carbon pricing. The more credible and predictable this strategy is over the coming decades, the smoother will be both divestment from brown technologies and investment in green technologies. Second, policy needs to help ensure that enough climate-neutral alternatives are available in time. Clear public support should be given to three system decisions about which we are sufficiently confident: the massive roll-out of renewable electricity generation; the electrification of significant shares of final energy consumption; and rapid phase-out of coal from electricity generation. For energy services where no dominant system has yet emerged, policy should forcefully explore different solutions by supporting technological and regulatory experimentation. Given the size and urgency of the transition, the current knowledge infrastructure in Europe is insufficient. Data on the current and projected state of the energy system remains inconsistent, either published in different places or not at all. This impedes the societal discussion. The transition to climate neutrality in Europe and elsewhere will be unnecessarily expensive without a knowledge infrastructure that allows society to learn which technologies, systems, and polices work best under which circumstances.
