Post-Keynesians focus on the analysis of capitalist economies, perceived as highly productive, but unstable and conflictive systems. Economic activity is determined by effective demand, which is typically insufficient to generate full employment and full utilisation of capacity.

Complexity economics focuses on interactions and interdependencies between individuals and structures in economic systems. Those are systems of organised complexity. High importance is given to the analysis of networks.

The core idea of ecological economics is that human economic activity is bound by absolute limits. Interactions between the economy, society and the environment are analysed, while always keeping in mind the goal of a transition towards sustainability.

Der Fokus der Verhaltensökonomik liegt auf dem beobachtbaren Verhalten von Menschen und deren Entscheidungen.

Der Fokus des Postkeynesianismus liegt auf der Analyse kapitalistischer Ökonomien. Diese werden als sehr produktive, jedoch instabile und konfliktive Systeme angesehen. Wirtschaftliche Aktivität wird von der effektiven Nachfrage bestimmt, die in der Regel keine Vollbeschäftigung und Vollauslastung der Kapazitäten garantieren kann.

Der Fokus der Komplexitätsökonomik liegt auf den Interaktionen und Wechselwirkungen zwischen Individuen und Strukturen wirtschaftlicher Systeme. Diese werden als Systeme organisierter Komplexität aufgefasst. Ein besonderes Augenmerk liegt auf der Analyse von Netzwerken.

This article outlines the fundamental challenges of democratically planned economies and categorises proposed models into six groups, each of which approaches planning and coordination at different levels of authority and between myriad economic units in a particular way, taking into account efficiency as well as democratic principles and environmental and social sustainability. Through a classification system based on decision-making authority and mediation mechanisms, the article provides a framework for understanding and comparing these models. By examining their different approaches, it offers insights into the complexities and potential paths of democratically planned economies in the 21st century.
