Ekonomisk politik och födelsetal – en analys av effekter och evidens

Sammanfattning

Den femte skriften från regeringens utredning Framtid med barn. Studien analyserar hur ekonomisk politik påverkar födelsetal och konstaterar att strukturella reformer inom bostad, arbetsmarknad och välfärd är viktigare än enbart ekonomiska transfereringar för att vända Sveriges historiskt låga födelsetal.

Sammanfattning

Circular economy systems are often designed with a focus on material flows and technological substitution, but their ecological performance is also shaped by geography. As a circular economy expands geographically, it encounters rising institutional diversity, logistical constraints, and behavioral divergence. The paper introduces a framework, based on lessons from the plastics industry, that models how spatial frictions—defined across regulatory, logistical, behavioral, economic, and coordination dimensions—accumulate with scale and undermine system performance. Costs escalate, and reliability deteriorates as circular systems become more spatially dispersed. These dynamics can result in delayed material recovery, inconsistent quality, and increased ecological inefficiency, even when technical feasibility exists.

A transition probability analysis of material flows in the European aggregates industry

Sammanfattning

Recycled aggregates materials are often relegated to downcycled applications such as backfilling. Different barriers limit their reintegration into higher-value construction use. This paper develops a probabilistic model of material flows using a Markov chain framework to simulate transitions between four states: Input, Use/Waste, Recycling, and Disposal. The model draws on Eurostat data covering non-metallic minerals in 27 EU Member States (2014–2023) and incorporates barrier-adjusted transition probabilities reflecting economic, technological, institutional, and social constraints. Scenario simulations reveal that improvements in recycling probabilities can yield nonlinear gains in material retention. However, once structural barriers are introduced, system performance declines sharply—even under favourable technical assumptions. The results suggest that modest policy interventions may have outsized effects if targeted toward key transition points.
