Critique of neoclassical economics is presented and contrasted with the more realistic assumptions made by an complex adaptive systems and evolutionary approach.
Steve Keen discusses DSGE modeling and microfoundations by asking the question if it is ideologically possible to derive macroeconomics from microeconomics.
Wolfram Elsner stellt in dieser Vorlesung die Charakteristika und grundlegende Konzepte der evolutionären institutionelle Ökonomik dar und kontrastiert dieser immer wieder mit denen der Neoklassik (u.a. im Bezug auf Märkte oder offene Systeme). Hierbei präsentiert er insbesondere die Beiträge Thorstein Veblens. Elsner skizziert evolutionäre Prozesse und stellt die Frage, welche Rolle Institutionen hierbei zukommt. Diese Ausführungen schmückt er mit zahlreichen Anekdoten.
Zunächst werden zentrale Aspekte der Institutionellen Ökonomik als Paradigma in diesem Vortrag erläutert, wie mulitdimensionale Akteure, Dynamiken, Interdependenzen, Komplexität, Populationsdenken und Institutionen. Danach wird die historische Genese Institutioneller Ökonomik von Mandeville und Smith, über Malthus und Darmwin hin zu US-Institutionenökonomen erläutert. Zudem werden Einblicke ins Komplexitätsdenken in Bezug auf das Finanzsystem gegeben.
James Glattfelder publizierte eines der aufsehenerregenden Paper der letzten Jahre. Mit Hilfe der Methoden der Komplexitätsökonomik - namentlich der Netzwerkanalyse - legt er Machtstrukturen von Großkonzernen und Abhängigkeiten in der Finanzbranche offen. In diesem dreistündigen Workshop erklärt er das theoretische Fundament der Komplexitätstheorie, zeigt die Grenzen der klassischen Ökonomik auf und stellt eines seiner Paper vor. Die Folien zur Präsentation sind hier abrufbar: http://www.boeckler.de/pdf/v_2016_08_12_glattfelder_slides.pdf
Diese Vorlesung gibt einen ersten Einblick in die Komplexitätsökonomie.
On this episode of the Hayek Program Podcast, Professor Roger Koppl talks with Hayek Program Research Fellow Solomon Stein about his research on experts, evolution, and the dynamics of epistemics, his career, and in what future direction(s) he thinks Austrian economics will go.
Antoine Godin gives a bright, illustrated, introduction to agent-based, stock-flow-consistent modeling, with a clear focus on the agent-based aspect.
This lecture is all about the challenge to include heterodox approaches into macroeconomics. After giving an overview of recent approaches to that problem Professor Michael Roos presents the theoretical framework of Complexity Economics as a means to combine behavioral aspects with macroeconomics.
"Why information grows" by Cesar Hidalgo and the atlas of economic complexity. César visits the RSA to present a new view of the relationship between the individual and collective knowledge, linking information theory, economics and biology...
As seen with the United Nations significant promotion of the Sustainable Development Goals (SDGs) in the past few years, the issue of global development is of growing concern to many international organizations. As humanity continues to become more interconnected through globalization, the inequalities and injustices experienced by inhabitants of impacted countries becomes increasingly clear. While this issue can be observed in the papers of different types (e.g., different schools of thought) of economists throughout the world, the work of behavioral and complexity economists offer a unique, collaborative perspective on how to frame decisions for individuals in a way that can positively reverberate throughout society and throughout time.
This article, looks at the complex interaction between an urban economy and the vegetation within that urban area. In summary, numerous studies have found a positive link between increased vegetation and social as well as personal health. It makes a case for increasing urban vegetation as a way to benefit local economies.
In this blog article, Dirk Brockmann illustrates how strong heterogeneities, cluster-like structures and high variability in node connectivities can naturally emerge in growing networks.
How countries achieve long-term GDP growth is up there with the most important topics in economics. As Nobel Laureate Robert Lucas put it “the consequences for human welfare involved in questions like these are simply staggering: once one starts to think about them, it is hard to think about anything else.” Ricardo Hausmann et al take a refreshing approach to this question in their Atlas of Economic Complexity. They argue a country’s growth depends on the complexity of its economy: it must have a diverse economy which produces a wide variety of products, including ones that cannot be produced much elsewhere. The Atlas goes into detail on exactly what complexity means, how it fits the data, and what this implies for development. Below I will offer a summary of their arguments, including some cool data visualisations.
Can pluralism in economics be useful to tackle the fight against climate change? How can diversity in methods and ideas allow for a better understanding of the issue of the climate crisis? What solutions do different schools of thought offer to overcome the most pressing challenge of the 21st Century? Our Rethinker Henrika Meyer will give you some answers and give you a glimpse of the solutions pluralism offers to tackle the fight against climate change.
This article considers the strengths of agent-based modelling and the ways that it can be used to help central banks understand the economy. These models provide a complement to more traditional economic modelling which has been criticised in the wake of the Great Recession.
From the two premises that (1) economies are complex systems and (2) the accumulation of knowledge about reality is desirable, I derive the conclusion that pluralism with regard to economic research programs is a more viable position to hold than monism. To substantiate this claim an epistemological framework of how scholars study their objects of inquiry and relate their models to reality is discussed. Furthermore, it is argued that given the current institutions of our scientific system, economics self-organizes towards a state of scientific unity. Since such a state is epistemologically inferior to a state of plurality, critical intervention is desirable.
Dies ist eine Sammlung von Texten und Abbildungen zu verschiedenen ökonomischen Perspektiven. Zu Beginn der Sammlung wird jede ökonomische Perspektive einzeln vorgestellt. Im zweiten Teil werden alle Perspektiven miteinander verglichen, damit Gemeinsamkeiten und Unterschiede erkennbar werden. Die Texte in dieser Sammlung sind bewusst einfach gehalten, da sie eine Einführung in die Thematik darstellen. Die Sammlung ist zudem auf die Darstellung einiger Perspektiven beschränkt und deckt bei Weitem nicht das gesamte Spektrum pluraler Ökonomik ab.
Modern authors have identified a variety of striking economic patterns, most importantly those involving the distribution of incomes and profit rates. In recent times, the econophysics literature has demonstrated that bottom incomes follow an exponential distribution, top incomes follow a Pareto, profit rates display a tent-shaped distribution. This paper is concerned with the theory underlying various explanations of these phenomena. Traditional econophysics relies on energy-conserving “particle collision” models in which simulation is often used to derive a stationary distribution. Those in the Jaynesian tradition rely on entropy maximization, subject to certain constraints, to infer the final distribution. This paper argues that economic phenomena should be derived as results of explicit economic processes. For instance, the entry and exit process motivated by supply decisions of firms underlies the drift-diffusion form of wage, interest and profit rates arbitrage. These processes give rise to stationary distributions that turn out to be also entropy maximizing. In arbitrage approach, entropy maximization is a result. In the Jaynesian approaches, entropy maximization is the means.
Das Seminar wirft einen historischen Blick auf Fragen ökonomischer Entwicklung und ökonomischer Theorie und verbindet eine Einführung in die Wirtschaftsgeschichte mit einer vergleichenden Diskussion unterschiedlicher ökonomischer Denkrichtungen und Theorien.
This course focus on the behaviour of individuals from an pluralist economic and an interdisciplinary bevavioural science apprach.
Jason Smith takes a stab at blind faith in the efficiency of the price mechanism to provide market information. To do so, he calls upon Information Theory and Generative Adversarial Networks to argue the price mechanism is faulty and skewed towards supply.
This paper provides a logical framework for complexity economics Complexity economics builds from the proposition that the economy is not necessarily in equilibrium economic agents firms consumers investors constantly change their actions and strategies in response to the outcome they mutually create This further changes the outcome which requires them …
Complexity economics and institutional economics are complementary approaches to studying the economy. They can pool their methods and foundational theories to explain the mechanisms that underlie economies.
This course is an introduction to the economic theories of financial crises It focuses on amplification mechanisms that exacerbate crises such as leverage fire sales bank runs interconnections and complexity It also analyzes the different perspectives on the origins of crises such as mistaken beliefs and moral hazard and discusses …

The 2007-2008 financial crisis exposed the shortcomings of mainstream economic theory with economists unprepared to deal with it. In the face of this, a major rethinking of economics seems necessary and in presenting alternative approaches to economic theory, this book contributes to the rebuilding of the discipline.
The Microeconomics of Complex Economies uses game theory, modeling approaches, formal techniques, and computer simulations to teach useful, accessible approaches to real modern economies.
This book presents recent thought on market efficiency, using a complex systems approach to move past equilibrium models and quantify the actual efficiency of markets.
The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central.
This book makes the case that economies are complex systems and in response to this, develops a unique dynamic nonequilibrium process analysis of macroeconomics.
