A wellbeing economy (WE) has been promoted by many advocates of a post-growth economy. Drawing on the growing WE literature, including detailed case studies of Wellbeing Economy Governments (WEGo), the article asks: does growing support for a WE represent a breakthrough for post-growth economic ideas? Or has mainstreaming the WE concept emptied it of radical post-growth content? The WE experience is interpreted in light of an earlier debate in the international development community over the mainstreaming of radical concepts that were purged of transformative meanings – becoming buzzwords that did not fundamentally alter existing practices. Wellbeing and the WE similarly risk becoming buzzwords: feel-good ideas that are hard to oppose, but which users can fill with their own meanings and political agendas. The WE's post-growth roots are contrasted with the pro-growth meanings given to it by organizations including the OECD and WEGo nations. The WE has nevertheless shown some promise in enabling limited steps in a post-growth direction in WEGo nations (within a broader context of continued pursuit of growth). The article presents – and invites debate on – some possible responses to resist dilution of the WE concept and advance a transformative post-growth vision.

The European Union regulation on deforestation-free products (EUDR) represents a policy innovation with important implications for the governance of global commodity chains. We discuss the risks and limitations of this policy derived from an ex-ante assessment of the robustness of its theory of change. For doing so, we use insights from the literature on zero-deforestation commitments and other private standards in value chains and from trade and deforestation patterns in three relevant producer countries (Brazil, Colombia and Indonesia). Despite the potentially positive symbolic effect in mobilizing a global agenda for combating deforestation, the EUDR faces several drawbacks and risks associated with three of its constitutive features: To be demand-oriented, having the value chain as the unit of intervention and holding a high degree of unilateralism. We conclude that to be effective in curbing tropical deforestation, the Regulation must be complemented with international cooperation aiming to strengthen national policies with a territorial approach, as well as social movements addressing the underlying causes of forest loss and human rights violations in the territories where it takes place.

Crop diversification, or growing multiple crops in farmland, has received attention as a risk-reducing strategy for smallholders. This study attempts to show that poor and non-poor farmers adopt different strategies of crop diversification. We first conceptualize farmers’ heterogeneous motivations for crop diversification by introducing a subsistence constraint into a utility maximization problem under uncertainty. Using the Tanzanian National Panel Survey, we then examine whether past experiences of shocks affect the adoption of crop diversification differently between poor and non-poor farmers. We rely on a threshold model to estimate heterogeneous impacts between poor and non-poor farmers. We find that poor farmers adopt crop diversification for robust food securities in response to drought/flood and large increases in food prices for purchase. In contrast, non-poor farmers adopt crop diversification to stabilize market income in response to large increases in input prices and large declines in crop prices for sale.

In recent years, a small but rapidly growing field of modeling alternatives to growth as represented by the de- (DG) and post-growth (PG) discourses has emerged. We compare selected model characteristics of 75 DG and PG related modeling studies, compiled through a systematic literature review (2000−2023), and link model structures and results to different theoretically contested debates surrounding DG/PG. The reviewed studies cover different geographical and temporal scopes, economic theories, modeling techniques and operationalizations of DG/PG. The majority of studies models DG/PG as intentional transition and does not question its compatibility with a capitalist system, while more radical strands of the DG/PG discourse are excluded. Although DG/PG modeling exercises frequently explore the effects of sustainability policies, they represent only a fraction of theoretical DG policy proposals, with the most frequent being: working time reduction, maximum income caps, carbon taxes and a universal basic income. DG/PG modeling studies have demonstrated the importance of integrating biophysical constraints in economic modeling but also have quantitatively assessed the feasibility of environmental integrity and social well-being without growth. Nonetheless, future modeling could be rendered more realistic by paying more attention to the Global South, introducing heterogeneous agents driving sustainability transitions and including multiple planetary boundaries.

The European Union (EU) relies on imported raw materials to manufacture renewable energy, digital, mobility, aerospace, and defence technologies. A circular economy can mitigate this critical dependency, for example by recycling materials or remanufacturing products locally. These resource efficiency strategies, however, require new supply chain configurations supported by research and innovation. While this is taking place in few selected supply chains, notably lithium-ion battery technology, little is known about circularity for most critical raw materials and their applications. Information is scattered across industry players and disciplinary competences, or not publicly available due to confidentiality concerns. This article presents a case study on titanium metal circularity in the aviation and defence sectors. The results inform three industrial policy recommendations to mitigate the risk of supply disruption in the EU, aggravated by Russia's invasion of Ukraine. Based on the case study, a methodological framework is proposed to guide future research on circularity for resource security. This subject requires urgent attention to achieve EU strategic autonomy objectives, against the background of climate change, resource depletion and waste management challenges in a complex geopolitical landscape.

Climate challenge can be modelled as a multiplayer prisoner’s dilemma where ecological action – e.g., purchasing an electric car or adopting sustainable life-styles – is costly in terms of economic resources, time, and effort. The prisoner’s dilemma structure of the game implies that, even though the social benefit is maximized – and every player would be better off – with everyone taking ecological actions, the strategy profile with no player taking action is a Nash equilibrium, assuming players have purely self-regarding preferences. In this paper we analyse how this ecological dilemma is affected by people’s perceptions. Using the European Social Survey, we study how urgent the climate threat is perceived by respondents and their beliefs about other countries’ actions. Theoretical predictions suggest that the former increases, while the latter does not affect individual willingness to act ecologically when introducing heterogeneity about the effect of worry on intrinsic motivations. Our empirical findings however show that both factors positively affect willingness to act. We interpret the positive effect by arguing that intrinsic motivations are also affected by other people action and show that the effect is weaker as social capital increases.

This paper aims to explore opportunities for integrating Behavioral Economics (BE) into Ecological Economics (EE). By examining the frames of analysis for both disciplines, this study categorizes BE as operating at the individual level (i-frame), while EE addresses systemic aspects of society (s-frame) and extends its considerations to the biosphere (n-frame), advocating for collective action through bottom-up intermediate-level interventions (c-frame).

The study posits that EE can benefit from BE’s rich insights into human behavior and decision-making, especially for c-frame action strategies. However, integrating these disciplines requires finding common ontological and epistemological ground to avoid eclecticism and methodological flaws. The integration is approached in two steps: first, adapting BE epistemology to the systems thinking approach of EE, and second, addressing the ontological gap in BE regarding the world surrounding the individual. This paper argues that embedding BE within EE’s ontology points to the necessity of c-frame thinking for human decision-making.

A case study of the ex-GKN factory in Italy demonstrates the practical benefits of c-frame thinking in a complex decision process. An alliance of workers, researchers, and civil society movements collaboratively developed a future plan that considered the needs of all stakeholders, showcasing the effectiveness of collective action.

Managing pathogens is a challenge in biological production processes. To manage private risks and reduce externalities, biological controls leverage the technology of natural ecosystems and are often considered environmentally friendly alternatives to chemical controls. In salmon farming, parasitic sea lice reduce own-firm profitability by stressing fish and slowing growth and generate externalities by spreading to neighboring farms and threatening wild fish populations. Cleaner fish are a form of biological control based on ecological interaction that can be used instead of chemical control of sea lice, but little is known about their efficacy and value in commercial use. We estimate efficacy of cleaner fish using facility-level data. To identify exogenous variation in cleaner fish usage, we instrument site-level cleaner fish stocks using distance to cleaner fish farm with a commercial license. Cleaner fish use significantly reduces likelihood of sea lice levels exceeding regulatory threshold levels. Combining efficacy estimates with cost data and a structural model, we provide estimates of cost-effectiveness. Our results show that cleaner fish are privately cost-effective, which is consistent with high levels of adoption. However, cost-effectiveness also suggests that policy could encourage even more adoption of biological controls to reduce externalities.

Climate change has sparked a vivid discussion on its socio-economic risks, capturing the attention of academic circles and policymakers. While it is widely argued that a low-carbon transition should be socially just, the precise criteria that policies must adhere to, in order to be universally accepted as ‘just’, remain insufficiently defined. To fill this gap, we draw on relevant theories of distributive justice where equal responsibility should lead to equal outcomes. According to our definition, just transition policies should minimise relative costs for the most vulnerable groups. Furthermore, uneven responsibility for causing damages should be also taken into account by discounting the importance of relative costs of groups with high responsibility.
