Abstract:
Efforts to assess the possibilities for decoupling economic growth from negative environmental impacts have examined their historical relationship, with varying and inconclusive results. Part of the problem is ambiguity about definitions of environmental impacts, e.g. whether to use territorial or consumption-based measures of environmental impact. This paper shows that ambiguities arising from definitional changes to GDP are sufficiently large to affect the outcomes. I review the history of structural revisions to GDP using the example of the United States, and on international comparisons of purchasing power parity, compare decoupling results using various historical definitions of GDP on the same environmental indicator, and demonstrate that changing the GDP data vintage does impact decoupling results in qualitatively important ways, with and without purchasing power parity. Inconsistencies in economic measurement introduce an additional layer of ambiguity into historical decoupling evidence and model projection into the future. To advance debate and be clear about scenario assumptions, rigorous reporting of GDP definitions used and the sharing of data vintage for subsequent comparison and replication are urgently needed.

Abstract:
The distribution of ownership of transition risk associated with stranded fossil-fuel assets remains poorly understood. We compute global stranded assets of US$1.4 trillion in the upstream oil and gas sector as expectations change to be consistent with stated climate policies. We trace the equity risk ownership from these 43,439 assets through a global equity network of 1.8 million companies to their ultimate owners. Most of the market risk falls on private investors, overwhelmingly in OECD countries, including substantial exposure through pension funds. Financial markets are exposed to a US$690 billion correction, comparable to the mispricing that triggered the 2007-08 crisis. The ownership distribution also shows the large stake OECD investors have in the continued operation of fossil-fuel facilities incompatible with climate change mitigation goals.

Abstract:
The transition to a low‐carbon economy will entail a large‐scale structural change. Some industries will have to expand their relative economic weight, while other industries, especially those directly linked to fossil fuel production and consumption, will have to decline. Such a systemic shift may have major repercussions on the stability of financial systems, via abrupt asset revaluations, defaults on debt, and the creation of bubbles in rising industries. Studies on previous industrial transitions have shed light on the financial transition risks originating from rapidly rising “sunrise” industries. In contrast, a similar conceptual understanding of risks from declining “sunset” industries is currently lacking. We substantiate this claim with a critical review of the conceptual and historical literature, which also shows that most literature either examines structural change in the real economy, or risks to financial stability, but rarely both together. We contribute to filling this research gap by developing a consistent theoretical framework of the drivers, transmission channels, and impacts of the phase‐out of carbon‐intensive industries on the financial system and on the feedback from the financial system into the rest of the economy. We also review the state of play of policy aiming to protect the financial system from transition risks and spell out research implications.

4. Inequality in Energy Consumption: Statistical Equilibrium or a Question of Accounting Conventions?

Abstract:
Mitigating climate change requires information about the inequality in energy consumption. Recent contributions (Banerjee and Yakovenko, 2010; Lawrence et al., 2013; Yakovenko, 2010, 2013) have studied energy inequality through the lens of maximum entropy. They claim a weighted international distribution of total primary energy demand should approach a Boltzmann-Gibbs maximum entropy equilibrium distribution in the form of an exponential distribution, implying convergence to a Gini coefficient of 0.5 from above. The present paper challenges the validity of this claim and critically discusses the applicability of statistical equilibrium reasoning to economics from the viewpoint of social accounting. It is shown that the exponential distribution is only a robust candidate for a statistical equilibrium of energy inequality when employing one particular accounting convention for energy flows, the substitution method. But this method has become problematic with a higher renewable share in the international energy mix, and no other accounting method supports the claim of a convergence to a 0.5 Gini. We conclude that the findings based on maximum entropy reasoning are sensitive to accounting conventions and critically discuss the epistemological implications of this sensitivity for the use of maximum entropy approaches in social sciences.

5. Neither Crowing in nor Out: Public Direct Investment Mobilising Private Investment Into Renewable Electricity Projects

Abstract:
Rapid structural change towards a low-carbon energy supply requires significant additional investments into innovative but high-risk low-carbon technologies. Mobilising greater private investments requires applying the right policy instruments, but while fiscal measures and regulation have been well researched, systematic quantitative evidence about the effect of public direct investment is lacking. Absent empirical evidence, contradictory theoretical arguments claim that such public (co- )investments either ‘crowd out’ or ‘crowd in’ private investors. In this paper we show that the macroeconomic concept of crowding out/in is inapplicable to sectoral studies such as of renewable electricity. Instead, both neoclassical microeconomics and evolutionary economics suggest public direct investment to have a positive effect due to either externalities or market creation effects. We also provide the first quantitative estimate of the effect of public direct investment on private investment into renewable electricity technologies for 17 countries in the period 2004-2014. Using FGLS and static and dynamic GMM estimators, we find that public investments not only have a positive but also consistently the largest effect on private investment flows relative to feed-in tariffs, taxes and renewable portfolio standards in general, and for wind and solar technologies separately. Implications for policy aimed at accelerating the low- carbon transition are discussed.

7. Energy in Economic Growth: Is Faster Growth Greener?

Abstract:
An influential theoretical hypothesis holds that if aggregate productivity growth accelerates, then so does the decline in energy intensity. Whether faster growth is greener in this sense is crucial for modeling future growth and climate change mitigation, but empirical evidence is lacking. This paper characterizes the global, long-run historical relationship between changes in energy intensity and labor pro- ductivity growth rates. Basing estimates on an unbalanced panel of 180 countries for the period 1950-2014 and the world as a whole, it captures a significantly larger historical window than previous studies. The paper finds a stylized fact whereby the rate at which energy intensity changes is constant or even increases as labor productivity accelerates. Faster growth is not greener. This provides important new information for calibrating integrated assessment models, many of which make a green growth assumption in near term projections.

Abstract:
This paper surveys the current state of financing green growth in the energy sector, based on the insight that there are different qualities of finance. In past transformational changes in other sectors, public monies played a key role across the innovation landscape. Public financing was central also in a number of past national energy transitions, as reviewed here for Iceland (from fossil to geothermal energy), Norway (from mainly non-electricity energy to hydroelectricity), France (from oil to nuclear) and the United States (from conventional to shale gas). In the current transition to low-carbon energy supplies, there is much public activity, most directed and concerted in China, but also reasons to doubt it is enough and applied in the right places to be able to finance the transition to a low carbon sector on time scales consistent with current climate change mitigation targets. A discussion of opportunities and challenges to a more central role for public financing concludes, drawing also on insights from the recent mission-oriented innovation literature.

9. American Radical Economists in Mao’s China: From Hopes to Disillusionment

Abstract:
American radical economists in the 1960s perceived China under Maoism as an important experiment in creating a new society, aspects of which they hoped could serve as a model for the developing world. But the knowledge of ‘actually existing Maoism’ was very limited due to the mutual isolation between China and the US. This paper analyses the First Friendship Delegation of American Radical Political Economists (FFDARPE) to the People’s Republic of China in 1972, consisting mainly of Union for Radical Political Economics (URPE) members, which was the first visit of a group of American economists to China since 1949. Based on interviews with trip participants as well as archival and published material, this paper studies what we can learn about the engagement with Maoism by American radical economists from their dialogues with Chinese hosts, from their on-the-ground observations, and their reflection upon return. We show how the visitors’ own ideas conflicted and intersected with their perception of the Maoist practice on gender relations; workers’ management and life in the communes. We also shed light on the diverging conceptions of the role for economic expertise between URPE and late Maoism. As the first in-depth study on the FFDARPE we provide rich empirical insights into an ice-breaking event in the larger process of normalization in the Sino- U.S relations, that ultimately led to the disillusionment of the Left with China.
