Decoding the barriers for a circular plastics industry: An equation framework

Sammanfattning

Empirical research on barriers to a circular plastics economy has predominantly relied on case study approaches. While research has provided insights into the conceptual and anecdotal aspects of these barriers, a gap remains in the application of formalized methodologies to systematically understand and address them. This paper seeks to bridge this gap by developing an equation system tailored to the plastics industry, bringing clarity to the complex interplay of factors that constitute barriers to a circular economy. The study identifies four primary barriers to the circular economy, as documented in the literature between 2017 and 2024: economic, institutional and regulatory, technological, and social. The results include 24 equations, synthesized into four master equations. A mathematical case study demonstrates how numerical weights, and the relative importance of variables can differ between countries, offering a practical guide for applying the framework across diverse contexts. The study concludes that reducing regulatory ambiguity, scaling recycling infrastructure, and fostering consumer trust in recycled materials are critical steps. However, each country will face unique challenges, requiring policymakers to adopt tailored approaches and variable weighting.

Sammanfattning

Artificial intelligence is reshaping academia, but instead of liberating scholars, AI might keep them running faster just to stay in place. This paper theoretically explores how AI increases institutional expectations rather than reducing workload. Using a formal workload model, the study examines how automation affects academic tasks, revealing that while AI streamlines some processes, it also creates new responsibilities in research, publishing, and administration. A case study illustrates how scholars experience rising pressures to verify AI-generated work, adapt to changing publication norms, and meet intensifying institutional demands. The findings suggest that AI’s role in academia is not one only of simplification, but acceleration—a race where efficiency gains are quickly absorbed, where the pursuit of academic excellence becomes ever more demanding, and where scholars must continuously push forward, not to advance, but merely to avoid falling behind.

Sammanfattning

This report investigates the rationale, implementation challenges, and evolving global context of vertical industrial policy, with a particular focus on Sweden. Against the backdrop of recent global crises—including the 2008 financial crisis, the COVID-19 pandemic, and geopolitical disruptions following Russia’s invasion of Ukraine—the analysis explores how governments have re-evaluated the role of state intervention to bolster economic resilience and strategic autonomy. The report distinguishes between horizontal and vertical approaches, where vertical policy targets specific sectors or technologies considered critical for national development, such as green technology, semiconductors, and renewable energy. Drawing on economic theory and empirical evidence, the report outlines the key justifications for vertical industrial policy, including market failures, coordination problems, and the under-provision of public goods. It also addresses the limitations and risks associated with such policies, including information asymmetries, rent-seeking, and political capture. A central contribution is a decision-making framework designed to help policymakers assess when vertical industrial intervention may be justified and how it can be designed to minimize inefficiencies and unintended consequences. While the report takes a cautiously critical stance toward vertical industrial policy, it acknowledges its potential when implemented with clear objectives, regular evaluations, and institutional safeguards. The analysis highlights the need for a balanced and flexible approach, especially in the context of green transitions and geopolitical fragmentation.

Working Paper No. 383 Insider activism in the forest industry: An empirical public choice analysis

Sammanfattning

Insider activism—where bureaucrats use discretionary power to advance own ideological goals—has significant implications for regulatory stability and property rights security. Using the Swedish forestry industry as a case study, the purpose of this study is to investigate if insider activism affects the Swedish forestry sector and how such possible regulatory uncertainty influences economic decision-making. Assembled survey data suggest that forest owners perceive regulatory enforcement as unpredictable, leading to defensive actions such as premature harvesting to preempt restrictive future regulations. To explain these patterns, we apply public choice theory and a game-theoretic approach, demonstrating how bureaucratic drift, regulatory ratcheting, and time-inconsistency problems contribute to persistent distortions in forestry policies. Policy wise, the findings emphasize the need for judicial review, regulatory impact assessments, and clearer legislative mandates to reduce enforcement uncertainty and improve institutional trust. This research advances discussions on bureaucratic incentives, regulatory capture, and legal certainty in environmental policy.
