The book brings together representatives of three generations and three disciplines (economics, philosophy and journalism), who freely discuss the main “global social facts” (in the sense of Max Weber) that occurred during the first quarter of the 21st century and the perspectives opened up on the second quarter.  The debate focuses on five main themes: demographic change, technological and economic change, political recomposition, health protection and the climate challenge. The phenomena that have most marked the global consciousness since the beginning of the century are the rise of terrorism – marked by the attack on the World Trade Center – the financial crisis of 2008 and the development of AI since 2022.  These events have led to a questioning of the neoliberal principles defined by the Washington Consensus. The launch of the chatGPT software has revealed the creative destructive power of social networks and AI, and in particular, the ability of digital applications to influence, the monopolistic position of their developers and the speculative nature of their stock market shares. These events have contributed to the rise of populism and authoritarian regimes. In Europe, they have led to a reappraisal of the most permissive and expensive social models. The authors recognize that projecting the 2050 horizon is difficult. They envisage a “Europe that is undoubtedly greyer”, but more united between generations and within each generation.  The authors call for a more rational assessment of the impacts of AI on the organisation of work and social life, a “more participatory and local” democracy, a “reconciliation of health and care”, and a climate transition that better integrates short- and long-term requirements.   Through the sagacity of their exchanges, the authors invite readers to reflect on the control of their destinies.

Ferghane Azihari is the son of Comorian emigrants whose parents “did not only flee material poverty. They also escaped pollution that kills six to fifty times more in sub-Saharan Africa than in Western Europe”.  From the introduction, the tone is set for this fascinating critique of the current ecology in our countries.  He dismantles one by one the declinist, Malthusian and anti-capitalist arguments of these movements which, warm and sheltered, dream of becoming good savages again.  He demonstrates that far from ravaging the planet, the technical progress opposed by Greta Thunberg, Nicolas Hulot and others has made it possible to greatly improve the human condition, including in the poorest countries. In a dream world, hunter-gatherers have in reality destroyed more through their overexploitation of resources than agriculture has made it possible to reduce. Technical progress and the industrial revolution have gradually made it possible to reduce pollution in developed countries as well as reducing working hours.  The real solution is therefore to believe in technical progress, associated with individual property which allows the protection of wealth as opposed to collective property, where no one has an interest, as shown by the state of the ZAD of Notre-Dame des Landes.  Regressive ecology is a luxury of rich countries; are we going to force emerging countries to remain at their current economic level, or even regress?  The author also shows that the most radical ecologists are for the most part anti-capitalists who have been reconverted after losing their clientele to technical and social progress, and that this explains their hatred of property and progress. A work that goes against the grain and is ultimately beneficial at a time when prophets of doom are almost the only ones with the right to speak.

Right from the start of the book, the introduction is striking, because based on successive failures on the climate front, the economist fears, at worst, a possible collapse of civilization and, at best, the possible replacement of our liberal democracy by an illiberal and therefore less democratic system because of climate inaction. Through his book, he therefore proposes the solution of introducing a carbon price (CO₂ tax) that could help save the common good in terms of nature in relation to climate change. To do this, in the first part of the book, he shows that the problem of energy transition is a problem of allocating decarbonization efforts among a multitude of economic agents. He highlights a large number of quantified calculations between, on the one hand, the CO² emissions emitted by traditional economic activity, and on the other hand, the actions to be carried out today and tomorrow by economic actors in order to move towards the net zero emissions (NZE) objective by 2050 (limiting global warming to 1.5°C). Then, before tackling carbon taxation, he demonstrates the current contradictions of homo economicus, who wants to do something for the planet, but who in fact does not want to spend more for the same product/service; in other words, the social unacceptability of alternative climate policies. On this subject, he therefore addresses the fact of the stowaway, because the economic actor who acts on decarbonization bears the full cost, and does not benefit in any way from the climatic benefit of this action (the costs are private, and the benefits are socialized). In fact, he goes on to propose and explain his theory of introducing a single carbon tax (of the order of €250/T according to his calculations) equal to the carbon value. The principle being that everyone will make the effort to decarbonize if and only if its cost per ton of CO² avoided is lower than the carbon value. This assumes the establishment of a well-calibrated subsidy system, with this uniform carbon tax generating a social optimum. But in an open world, while the new presidency of the United States is making every effort to deploy its economy with traditional energies, the effort required must take place at the global level and not the national level, hence the problem of the stowaway. In addition, the author highlights an innovative idea proposing that the European Union set up an independent Carbon Central Bank (CCB) to manage the evolution of the price of carbon on an emission permit market covering the entire Union. Subsequently, the goal would be to raise the price of carbon to a level where oil and gas would no longer be competitive with renewable energies. Finally, while there is no simple solution to the energy transition, and many intellectuals today fail to see the challenges posed by the debate surrounding climate policies that are undermining our liberal democracy, economist Grollier simply wanted to show that carbon pricing was the least bad solution. This book helps us understand all the current economic issues we are facing without always realizing their full significance, as well as the major events that are shaping our century, such as electric cars, heat pump heating, soft mobility in cities, green steelmaking, e-fuels for aviation and maritime transport, etc. All that remains is to convince the global population… Christian Gollier is an economist, co-founder and director of the Toulouse School of Economics and his work focuses on the climate economy (recent works: “Entre fin de mois et fin du monde” and “Le climat après la fin du mois”) and on the science of decision-making in uncertainty.

Artificial intelligence has become a cross-cutting technology that concerns all economic sectors and has applications in all use cases as soon as there is a layer of analysis. AI has the potential for systemic transformation by simultaneously changing the way the entire economy produces, organizes and innovates. The financial sector is, of course, not exempt from these changes. Computers in the 1970s enabled the emergence of quantitative finance and the development of sophisticated mathematical models to assess risk and optimize portfolios. But AI is specific by its autonomy, its ability to interact in natural language, to adapt its decisions through learning, to process and analyze huge volumes of data in real time, and to convert textual information into investment strategies. These few examples, already adopted in daily operations, suggest disruptive upheavals in the sector. This issue of the “Revue financière d’économie,” edited by Marie Brière, explores the issues as well as the economic, financial and ethical challenges, and the impacts and risks associated with the increasing integration of AI in the financial sector. Thirteen leading contributors, such as Cédric Villani, Philippe Aghion, Agnès Bénassy-Quéré, to name but a few, provide a valuable synthesis around three main themes. The first is devoted to the economic and financial challenges of deploying AI. It addresses the strategic needs in terms of funding and research related to AI, ethical issues, recalling that humanity invests ten times more in AI and digital technology than in the ecological transition, the impacts on the dissemination of innovation and productivity and finally digital currencies and the role of fintechs as well as central banks. The second part addresses some  use cases of AI and generative AI in finance. The various contributors revisit integration strategies in scoring, payment default, loan applications, insurance claims management, and cyber risk prevention, but show that these productivity gains can be offset by new, less visible risks. In the last part of this issue, the experts focus on the risks and the different regulatory approaches, and in particular on the ability of regulatory authorities to use AI to assist them in their control mission.This issue of the “Revue d’économie financière” offers us a rather comprehensive approach to the current debates on the complex issues of the use of AI in the financial sector.

The authors respond to the main questions raised over the past thirty years by the impacts of global warming and the energy and ecological transitions. They recall the warnings issued since 1990 by the IPCC and other official bodies, as well as the (often disappointed) ambitions set out at the 29 Conferences of the Parties (COP) organized since 1995. They emphasize the importance of COP 21, held in Paris in 2015, which set a target of limiting global warming since the 19th century to 1.5°C by 2030 and achieving carbon neutrality by 2050. The authors reveal that IPCC reports have been the target of a veritable climategate, orchestrated by energy companies, which have sought to discredit the IPCC’s data, processing, and conclusions through biased studies. They also denounce banks that continue to finance projects that harm the environment. They point out that the multiple consequences (particularly on human health) of greenhouse gas (GHG) emissions are increasingly well documented and that a warming of 3°C or even 4°C would be catastrophic for the planet and humanity. They warn of the severity and simultaneity of recent natural disasters (droughts, floods, etc.). The authors are optimistic, however: they identify the devices to be implemented in order to achieve the objectives set by the COP: new instruments of “green finance”, alternative systems of heating, transportation and production, ecological materials… They show the progress of agroecology to preserve the soil and absorb GHGs, as well as the emergence of geoengineering that extracts carbon monoxide from the atmosphere. They hold up European countries as examples for nation states that are less economical with fossil fuels, such as China and the United States. Alain GRANDJEAN is the co-founder of the firm Carbon 4.

In this latest opus, the authors, who are not at their first book together, look at some long-term proposals to reinvent a social model for France and Europe vis-à-vis the ambitions of the United States and China. This first quarter of the 21st century has been marked by a spectacular drop in the European economy and even more so in the French economy. Since 2002, the US GDP has grown twice as fast as the European GDP. And this slide continues regardless of the elements of analysis: productivity, R&D, investment, employment rate, trade balance, training, etc. France has even fallen behind on its own continent compared to its neighbors. The irresistible French de-industrialization has not been offset by the development of a significant technological sector, the debt and the trade deficit are abyssal, the quality of public services is deteriorating despite an ever-increasing budget deficit, and finally, the wealth per capita is 15% lower than that of Germany. Europe is at odds with Schumpeter and is paying a high price for its risk aversion. 54% of American R&D is devoted to new technologies compared to 15% in Europe, which prefers to continue investing in its old industry. Nine of the top ten European capitalizations are in traditional sectors, while nine out of ten of the American ones are related to new technology and AI. The major advantage of the American model lies in an ecosystem that is conducive to innovation and investment, in stark contrast to the European model, which is hampered by a restrictive fiscal, legislative, and regulatory framework. It could be summed up in a slogan: risk appetite versus the “precautionary principle.”But this very “business friendly” American model hides weaknesses. Inequalities and impoverishment continue to grow, the exorbitant cost of care is a factor of indebtedness, and the financial situation of the Federal State, despite or because of the dollar, is catastrophic. While Donald Trump has promised the Americans to return to the golden age of the McKinley period, will a weakened and demoralized Europe be able to react? To achieve this, it will need to escape the trap of weak growth, regain its dynamism, and defend its position in the global arena. The authors make concrete proposals at both the national and European levels. The urgent reforms needed in France are well known, as are the solutions. Choices will have to be made if we want to preserve our social model. But above all, we will need to find consensus and active involvement in a context where exasperation, deadly dialectics, and mistrust of our leaders are preventing necessary reforms and fueling accusations of democratic models’ inefficiency.

Based on an extensive research program described in the book, the authors’ collective provides a precise overview of the different forms of associations and their resources; with, among other things, the extent of their dependence on public funding.The first part of the book is devoted to setting the framework of associations in the broad sense and to understanding their functioning as well as the plurality of market and non-market financial resources. The analysis of monetary resources shows that associations continue to drain public funding that is decisive for their socio-economic model in order to achieve their budgetary balance. The role of volunteering also remains major in the emergence of projects and in the functioning of associations, although some of them are becoming professionalized.The second part of the book focuses on the socio-economic models of associative social centers. The latter developed at the end of the 19th century in bourgeois circles. Their initial objective was to strengthen family and neighborhood ties during this period of industrial and urban development. Today, according to their purpose, social centers share the goal of fostering links and exchanges. The authors raise the issue of the monetary valuation of volunteering in the accounting balance sheets of this type of association, due to a lack of method.In a third part, the authors present the socio-economic model of “third-places”. This category is defined as a “space of sociability, of citizen initiative, where a community can meet, gather, exchange and share resources, skills and knowledge”. Whatever their actions, “third-places” claim autonomy by relying on non-monetary resources but still remain dependent on public funding.The fourth part of the book focuses on socio-economic models in the field of integration. The authors present their research and analysis in the IAE (Insertion par l’Activité Economique) sector and on the TZC (Territoires Zéro Chômeurs) experiment.In conclusion, the authors highlight three avenues for reflection: the mobilization of work and volunteering, access to capital, and the evaluation of social utility towards social impact.This book is very widely documented and makes it a collection that can serve as a reference in their field. With a very academic style, a technical and specialized vocabulary, this book is aimed at seasoned readers.The Inter-University Network of the Social and Solidarity Economy (RIUESS) was established in the year 2000. Today, it brings together around twenty French universities around its objective: to promote training and research in the social and solidarity economy and to encourage exchanges and shared initiatives between SSE actors. This book was produced by a multidisciplinary team composed of members of the network, economists, sociologists, and a philosopher,  constituting the RIUESS-MSE collective.With contributions from Mariagrazia Cairo Crocco, Melaine Cervera, Cyrille Ferraton, Anne Fretel, Laurent Gardin, Patrick Gianfaldoni, Florence Jany-Catrice, Vincent Lhuillier, Pierre Robert, Delphine Vallade.Reading note by Sophie FRIOT
