Abstract:
Higher levels of economic activity tend to go hand-in-hand with additional energy use and consumption of natural resources. As fossil fuels still account for 80 percent of the global energy mix, energy consumption remains closely related to greenhouse gas emissions and hence to climate forcing. This paper explores whether decarbonisation and economic growth are compatible or whether the world economy needs to grow less to be able to reduce greenhouse gas emissions fast enough to reach net zero in 2050. The literature provides profoundly different answers to this question, with scholars positioning along a spectrum that extends from the most optimist version of ‘green growth’ theories to sceptical ‘degrowth’ theories. While globally, CO2 emissions per unit of GDP are declining, the decoupling rate from 1995 to 2018 was only -1.8 percent annually. To achieve net zero by 2050, the rate would have to accelerate to -8.7 percent, assuming population and GDP growth projections as given, or by a factor of almost five. To keep GDP growth and population at their projections and thus reject the proposition of de-growth, decoupling would have to accelerate massively. Two avenues are crucial: reducing the energy intensity of production and/or the emissions intensity of energy. The huge fall in the price of renewable energy provides hope that decoupling can accelerate. Decoupling rates have accelerated in the last decade and decoupling is substantially faster in the European Union. In the EU, we estimate that decoupling only has to accelerate by a factor of 2.5. We do not think degrowth propositions advanced in the literature will be pursued and therefore focus on the main challenges that must be tackled to achieve decoupling. Unprecedented efforts are required to achieve green growth. But hoping for humanity to sacrifice growth appears unrealistic.

882. A new integrated-value assessment method for corporate investment

Author:

Content Type:
Policy Brief
Institution:

Abstract:
Companies are under pressure to change their business models and become more sustainable. Corporate governance codes across Europe have introduced the term ‘long-term value creation’ to capture companies’ social responsibility. However, the concept of long-term value creation lacks tools that would enable its application. Companies still steer their investments based on outdated valuation methods, which are entirely based on financial value. The concept of integrated value would give substance to long-term value creation. Integrated value involves managing and balancing the financial, social and ecological value dimensions of companies. Impact measurement aims to capture social and ecological value alongside financial value. The first impact measurements of companies are already taking place using cost-based methods. International reporting standards have been developed to harmonise the measurement and reporting of sustainability information. But there is no guidance on how to use the impact information. This policy contribution sets out a proposal on the use of impact information to steer investment decisions. We introduce decision rules based on integrated value. These decision rules allow for the prioritisation of specific types of value, in line with a company’s purpose. A practical example shows how this new decision model can help companies improve their valuation profiles. Society expects companies to include social and environmental value in their strategies and business models in order to retain (or regain) their social license to operate. Further investment in deepening measurement and decision-making methods based on integrated value can speed up the process. The willingness of corporate executives to use these new methods will be decisive for success.

883. Do robots dream of paying taxes?

Abstract:
Robot taxes embody the more futuristic challenges of managing automation and legacy workers. As machines and artificial intelligence take on more roles that used to be performed by humans, policymakers and technologists are assessing the costs this transition imposes and what parts of society will pay them. A robot tax on companies that replace employees with automated systems is easy to dismiss in its most simplistic forms but should be considered in the context of managing the next industrial revolution. A robot tax is a political construction, a way to shape democratic debate around technological shifts and societal needs. It is a construct of the public debate, and as such can contribute to broader discussions about how to make sure profitable companies pay their way in the economy. The political capital of ‘replacement robot’ imagery may be useful in designing a tax framework for legacy firms making the most of new economic opportunities. It is best to consider a ‘robot tax’ as a rallying concept for targeted levies. These policies should target finance and other data-driven sectors as well as traditional manufacturing and mining automation. Policymakers should consider overall employment, specific job losses and how to assess firms that make layoffs in specific areas of their workforces. This last will be especially difficult in cases where total headcount rises, even though some generations of employees may be put out of work. Tax policy can compensate for distortions due to shifts from human-driven to capital-intensive production in specific sectors. On the revenue side, there should be appropriate expectations of what a tech tax can raise and over what period, on the scale of targeted retirement assistance or retraining programmes with measurable outcomes, not long-running cash cows. Smaller and more innovative firms should not be asked to contribute disproportionately, particularly in legacy markets that are hard to break into, and they should be eligible for waivers and exemptions. Policymakers should stress that asking producers to help pay the costs of societal change is not immediately equivalent to stifling innovation, and they should make every effort to design policies in ways that protect against this type of side effect. Finally, any new tax on employers needs to fit with broader discussions of the corporate fair share, and with taxing the most profitable parts of the economy instead of relying on workers and consumers to foot society’s bills.

884. Does money growth tell us anything about inflation?

Author:

Content Type:
Working Paper
Institution:

Abstract:
Economists and central bankers no longer consider monetary aggregates relevant for inflation forecasts. We explain this neglect by advancing and testing the hypothesis that monetary aggregates are only relevant for inflation in unsettled monetary and inflationary conditions. When inflation is basically stable around the central bank target (1.9 percent), as it has been in most of the last two decades, there is no apparent relationship between monetary aggregates and inflation. This is not surprising: there is not much to be explained about a constant.

885. Towards efficient information sharing in network markets

Abstract:
Digital platforms facilitate interactions between consumers and merchants that allow collection of profiling information, which drives innovation and welfare. Private incentives, however, lead to information asymmetries resulting in market failures both on-platform, among merchants, and off-platform, among competing platforms. This paper develops two product-differentiation models to study private and social incentives to share information within and between platforms. We show that there is scope for ex-ante regulation of mandatory data sharing that improves social welfare better than competing interventions, such as barring entry, break-up, forced divestiture or limiting recommendation steering. These alternate proposals do not make efficient use of information. We argue that the location of data access matters and develop a regulatory framework that introduces a new data right for platform users, the in-situ data right, which is associated with positive welfare gains. By construction, this right enables effective sharing of information together with its context, without reducing the value created by network effects. It also enables regulatory oversight but limits data privacy leakages. We discuss crucial elements of its implementation in order to achieve innovation-friendly and competitive digital markets.

886. Biometric technologies at work: a proposed use-based taxonomy

Author:

Publication Date:

Content Type:
Policy Brief
Institution:

Abstract:
Biometric technologies have in principle the potential to significantly improve worker productivity, security and safety. However, they are also a source of new risks, including exposure to potential personal data abuse or the psychological distress caused by permanent monitoring. The European Union lacks a coherent regulatory framework on the mitigation of risks arising from the use of biometric technologies in the workplace. We propose a taxonomy to underpin the use of artificial intelligence-powered biometric technologies in the workplace. Technologies can be classified into four broad categories based on their main function: (1) security, (2) recruitment, (3) monitoring, (4) safety and well-being. We identify the benefits and risks linked to each category. To be more effective, EU regulation of artificial intelligence (AI) in the workplace should integrate more detail on technology use. It should also address the current scarcity of granular data by sourcing information from users of AI technologies, not only providers. There is an untapped potential for technology to address workplace health hazards. Policymakers should design incentive mechanisms to encourage adoption of the technologies with the greatest potential to benefit workers. Artificial intelligence users, in particular bigger companies, should be required to assess the effect of AI adoption on work processes, with the active participation of their workforces.

887. mRNA vaccines: a lucky shot?

Abstract:
MRNA technology has proved in the context of the COVID-19 pandemic its breakthrough value as a basis for vaccines. There has been rapid development of highly safe, effective and robust mRNA vaccines, and these can be delivered at large scale. Yet the technology is the result of a long process of accumulation of innovation and capacity. It was a bumpy process that could easily have turned out differently. The mRNA vaccines story suggests that a vibrant vaccine ecosystem cannot be taken for granted in terms of delivering the breakthroughs needed for global pandemic preparedness and response. This paper examines the background of mRNA technology development to understand better how public vaccine research and development policy can be improved to generate the full global social benefits from breakthrough novel vaccine technologies, like mRNA.

888. Market power and artificial intelligence work on online labour markets

Abstract:
The views are those of the authors and should not be regarded as stating an official position of the European Commission. Frank Mueller-Langer gratefully acknowledges financial support from a research grant of the University of the Bundeswehr Munich. We investigate three alternative but complementary indicators of market power on one of the largest online labour markets (OLMs) in Europe: (1) the elasticity of labour demand, (2) the elasticity of labour supply, and (3) the concentration of market shares. We explore how these indicators relate to an exogenous change in platform policy. In the middle of the observation period, the platform made it mandatory for employers to signal the rates they were willing to pay, as given by the level of experience required to perform a project: entry, intermediate or expert level. We find a positive labour supply elasticity ranging between 0.06 and 0.15, which is higher for expert-level projects. We also find that the labour demand elasticity increased while the labour supply elasticity decreased after the policy change. Based on this, we argue that market-designing platform providers can influence the labour demand and supply elasticities on OLMs with the terms and conditions they set for the platform. We also explore the demand for and supply of AI-related labour on the OLM under study. We provide evidence of a significantly higher demand for AI-related labour (ranging from +1.4 percent to +4.1 percent) and a significantly lower supply of AI-related labour (ranging from -6.8 percent to -1.6 percent) than for other types of labour. We also find that workers on AI projects receive 3.0 percent to 3.2 percent higher wages than workers on non-AI projects.

889. Timely measurement of real effective exchange rates

Author:
Zsolt Darvas
Publication Date:

Content Type:
Working Paper
Institution:
Bruegel
Abstract:
We demonstrate that short-run real exchange effective rate changes are dominated by nominal effective exchange rate changes, while inflation rates are sticky and contribute little to short-run real exchange rate changes. These observations allow a rather accurate real-time approximation of the real effective exchange rate using actual nominal exchange rate data and forecast inflation data. We measure the approximation error and find it is minor for most countries and sizeable only for a few countries experiencing high and volatile inflation. For a set of countries, the revision in our estimates using real-time data is slightly lower than the revision in World Bank estimates and much lower than International Monetary Fund estimates. By considering two widely studied economic issues, unit root testing in real exchange rates and nominal exchange rate forecasting with the real exchange rate, we find that using a version of real exchange rates based on approximated monthly price level data instead of actual price level data hardly changes the conclusions on unit roots and forecasting. By combining alternative data sources for exchange rates and consumer prices, we calculate up-to-date monthly real effective exchange rates for 177 countries and the euro area. Our dataset, which is frequently updated, includes more than twice as many observations as the second most comprehensive dataset.

890. Climate-related Security Risks in the 2020 Updated Nationally Determined Contributions

Author:

Institution:

Abstract:
Nationally determined contributions (NDCs) are the central instrument for states to communicate their con­tribution to the 2016 Paris Agreement on climate change and reflect their wider approach to climate mitigation and adaptation. This SIPRI Insights paper analyses how the 2020 updated NDCs (16 submissions as of October 2020) discuss climate-related security risks and compares them with 2015. It finds that climate change is mainly seen as a risk to socio-economic development and human security and almost never as a risk to societal stability or the functioning of the state. The assessment of risks in NDCs largely focuses on direct climate impacts. This suggests that countries are currently not considering the risks from indirect climate impacts, including those that cross national borders, or the unintended adverse con­sequences of adaptation or mitigation responses. Going forward, countries will need to take account of the multi­faceted and transboundary character of climate risks in their NDCs in order to meet global expectations and goals.
