When imagining how a green transition can take place, the relationship between economic growth and environmental sustainability is commonly viewed in two ways: As ‘green growth, ’ where the two can be mutually supporting, and as ‘degrowth, ’ where they cannot. The two are considered mutually exclusive, internally coherent, and competing eco-political paradigms. Here, we conceptually analyze the literature and map standpoints within the two positions along nine dimensions covering national institutions, world order, and scientific cosmology. We find that there are substantial disagreements within as well as agreements between green growth and degrowth. In consequence, we argue that th..

This study investigates the evolution of France's carbon footprint from 2000 to 2014, with a particular focus on the role of international trade. During this period, France's territorial emissions decreased by 18%, yet its consumption-based footprint declined by only 5%. This divergence reflects an increase in emissions embedded in imports, which grew from 45% to 54% of the total. To analyze these dynamics, we develop a novel structural decomposition framework that disentangles the contributions of scale, composition, and technique effects from a consumption perspective. Our approach extends existing methods by explicitly distinguishing between domestic and foreign influences, and by separat..

The 2024 farmers' protests across Europe signaled widespread dissatisfaction in the agricultural sector. While low farm incomes and restrictive environmental regulations are commonly cited grievances, little is known about underlying motivations and individual farmers' reasons for protesting. This study explores individual farmers' protest motivations in Germany, France, Belgium, and the Netherlands to gain a deeper understanding of the diverse concerns shaping agricultural discontent across Europe. We analyze rich text data from 2232 farmers, collected through surveys using an open-ended question designed to elicit unprompted, top-of-mind protest reasons. By using a combination of hand and ..

This paper introduces a new approach to proving bootstrap consistency based upon the distribution of permutation statistics, using it to derive results covering fundamentally not-identically distributed groups of data, in which average moments do not converge to anything, with moment conditions that are less demanding than earlier results for either identically distributed or not-identically distributed data.

We study how passive investing affects asset prices. Flows into passive funds disproportionately raise the stock prices of the economy’s largest firms, and especially those large firms in high demand by noise traders. Because of this effect, the aggregate market can rise even when flows are entirely due to investors switching from active to passive funds. Intuitively, passive flows increase the idiosyncratic risk of large firms in high demand, which discourages investors from correcting the flows’ effects on prices. Consistent with our theory, prices and idiosyncratic volatilities of the largest S&P500 firms rise the most following flows into that index.

This paper examines the effects of a major 2012 student loan reform in Chile that reduced interest rates from 6% to 2% and introduced more flexible repayment terms. Unlike studies of initial loan implementation, this reform offers a rare opportunity to examine how changes in the cost of borrowing affect enrollment decisions among already-eligible students. Using rich administrative data and a difference-in-differences design, we estimate the effects of the reform on immediate enrollment, second-year enrollment, and second-year dropout. To strengthen causal inference, we complement our strategy with a difference-in-discontinuities approach that leverages eligibility thresholds. We find a comp..

This paper extends the existing individual decision-making framework of adapting to climate change by considering the effects of prior personal experience in shaping risk preferences. Conducting Prospect Theory-based “lab-in-field” risk experiments in rural areas of Xinjiang Province, we elicit Chinese farmers' risk curvature and probability bias by adopting more flexible Prelec's two-parameter probability functions. Using Bayesian approaches to estimation, we find that farmers' prior experiences not only provide information that influences the subjective distributions of future outcomes but also, by shaping farmers' personal risk preferences, affects how farmers absorb and update this i..

We evaluate the impact of attending two secondary free schools in England – new autonomous state-funded start-ups – using admission lotteries and a distance-based regression discontinuity design. We characterise each school’s ethos through text analysis of vision statements: one follows a 'no excuses' paradigm common among US charter schools; the other adopts a 'classical liberal', knowledge-rich approach. These features distinguish them from each other and from counterfactual schools attended by rejected applicants. Despite pedagogical differences, both schools significantly improve test scores, reduce absences, and lower student mobility. Our findings support policies promoting horiz..

North Korean leader Kim Jong-un’s attendance at China’s Victory Day parade in September reflects a potentially ominous development in Northeast Asia’s regional security landscape. At Tiananmen Square, Kim stood alongside Chinese and Russian leaders—just as his grandfather did in 1959—a display widely interpreted as a gesture of opposition to the United States and the Western-led…

South Korean President Lee Jae Myung’s recent appearance on a cooking reality TV show may seem like light entertainment, but it is actually reflective of a strategic highlighting of a key facet of U.S.-South Korea relations. According to KEI’s 2025 annual survey, food is both the most popular aspect of South Korean culture among Americans…

U.S. and South Korean defense authorities met for the fifty-seventh Security Consultative Meeting (SCM) on November 4 in Seoul. Conventionally, the SCM Joint Communiqué is released at the conclusion of the meeting; however, this year it was delayed, coinciding with the release of the long-awaited Joint Fact Sheet on U.S. President Donald J. Trump’s meeting…

Overeducation implies having a higher level of education than that required to perform a specific job. In this regard, a large body of literature shows that first-generation immigrants born in developing countries experience a higher likelihood of being overeducated than natives due in part to their foreign origin (i.e. immigrant overeducation). However, evidence is remarkably scarce regarding the overeducation of second-generation immigrants. Using a matched employer–employee database for Belgium over the period 1999–2016 and generalized ordered logit regressions, we contribute to the literature with one of the first studies on the intergenerational nexus between overeducation and origi..

This article aims to assess the impact of the Geographical Indications (GIs) protection policy on the sustainable development of agriculture in mainland France. More specifically, it analyses the impact over the last decade of the increase in the territorial magnitude of agri-food GIs on agricultural economic performance, agricultural employment and agricultural pressures on the environment (biodiversity and water quality). The magnitude of GIs is assessed using two distinct indicators: the proportion of farmers involved in GIs and the diversity of GI products within each territory. We use data at a fine territorial scale (cantonal level – NUTS4) and a meso-economic approach. We estimate a..

Partnerships have their own vision of sustainability, from formal broad concepts such as bioeconomy or blue economy to grounded-specific objectives. As highlighted in numerous studies, managing diverse visions towards a common goal can be challenging. This article seeks to explore the factors influencing sustainable value co-creation through a novel lens: the intermediaries operating at the partnership level. These intermediaries are potential key players in the success of partnerships focused on sustainable food and bioeconomy systems in Europe. To identify their roles and positions, three in-depth case studies were conducted on partnerships (Pôle Mer Mediterranée, Foodwest, and BIOEAST) ..
