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.
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.
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.
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.
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.
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.
Critique of neoclassical economics is presented and contrasted with the more realistic assumptions made by an complex adaptive systems and evolutionary approach.
In a span of around 12 weeks, the course covers a wide range of topics including agent-based modeling, networks, dynamic, chaos, information, fractals, cooperation models and scaling in biology and society. The course acts as a perfect beginner level introduction spanning a wide range of topics in the field of complexity.
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...
The Atlas of Economic Complexity is an award-winning data visualization tool that allows people to explore global trade flows across markets, track these dynamics over time and discover new growth opportunities for every country.
The usual background and distinctions between complexity and neoclassical economics are presented Neoclassical economics deals with perfectly rational representative agents this creates states of equilibrium On the other hand complexity economics relaxes these assumptions to deal with responsive agents in an uncertain dynamic environment this creates states of disequilibrium More …
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 …
In this course you'll learn about the tools used by scientists to understand complex systems. The topics you'll learn about include dynamics, chaos, fractals, information theory, self-organization, agent-based modeling, and networks.
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.
When Santa Fe Institute Scientists first started working on economics more than thirty years ago, many of their insights, approaches, and tools were considered beyond heterodox. These once-disparaged approaches included network economics, agents of limited rationality, and institutional evolution—all topics that are now increasingly considered mainstream.
This is a hands on four chapter course to learn how to better understand and act when faced with complex situations By the end of the course students will be able to take a story from the news describe what makes the situation complex and identify opportunities for effective action …
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.
The last 15 years have seen extensive research into ecosystem service valuation (ESV), spurred by the Millenium Ecosystem Assessment in 2005 (Baveye, Baveye & Gowdy, 2016). Ecosystem services are defined as “the benefits people obtain from ecosystems” (Millenium Ecosystem Assessment, p.V). For example, ecosystems provide the service of sequestering carbon which helps regulate the climate. Valuation means giving ecosystems or their services a monetary price, for example researchers have estimated that the carbon sequestration services of the Mediterranean Sea is between 100 and 1500 million euros per year. The idea of ESV was a response to the overuse of natural resources and degradation of ecosystems, allegedly due to their undervaluation and exclusion from the monetary economy. ESV can be used (1) for policy decision-making, for example allocating funding to a reforestation project (2) for setting payments to people who increase ecosystem services, for example a farmer increasing the organic carbon content of their soil, and (3) for determining fees for people who degrade ecosystem services, for example a company that causes deforestation.
Since the Middle Ages, literature has portrayed the economic world in poetry, drama, stories and novels. The complexity of human realities highlights crucial aspects of the economy. The nexus linking characters to their economic environment is central in a new genre, the "economic novel", that puts forth economic choices and events to narrate social behavior, individual desires, and even non-economic decisions.
The leading edges of economic thinking in the early 21st century are marked by a nascent pluralism - a positive valuing of difference and complexity - regarding the nature and evolution of human behaviour and economic organization. Economic Pluralism brings these pluralist sensibilities to the fore.
The Austrian tradition in economic thought had a profound influence on the development of post-war economics including neoclassical orthodoxy, game theory, public choice, behavioral economics, experimental economics and complexity economics.
To grasp sex in all its complexity, including its relationship to gender, class, race and power, Srinivasan argues that we need to move beyond the simplistic views of consent in the form of yes-no, to rather consider the more complex question of wanted-unwanted.
A historical glimpse of how economists of the 19th century debated the usefulness of mathematics to economics
A review of:  Intermediate Microeconomics, H.R. Varian  Mikrooekonomie, R.S. Pindyck, D.L. Rubinfeld  Grundzuege der mikrooekonomischen Theorie, J. Schumann, U. Meyer, W. Stroebele
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.
Evolutionary economics focuses on economic change. Hence processes of change such as growth, innovation, structural and technological change, as well as economic development in general are analysed. Evolutionary economics often gives emphasis to populations and (sub-)systems.
This course focus on the behaviour of individuals from an pluralist economic and an interdisciplinary bevavioural science apprach.
Austrian economics focuses on the economic coordination of individuals in a market economy. Austrian economics emphasises individualism, subjectivism, laissez-faire politics, uncertainty and the role of the entrepreneur, amongst others.
Institutional economics focuses on the role of social institutions in terms of laws or contracts, but also those of social norms and patterns of human behaviour that are connected to the social organisation of production, distribution and consumption in the economy.
This paper starts with an evaluation of three common arguments against pluralism in economics: (1) the claim that economics is already pluralist, (2) the argument that if there was the need for greater plurality, it would emerge on its own, and (3) the assertion that pluralism means ‘anything goes’ and is thus unscientific. Pluralist responses to all three arguments are summarized. The third argument is identified to relate to a greater challenge for pluralism: an epistemological trade-off between diversity and consensus that suggests moving from a discussion about ‘pros’ and ‘cons’ towards a discussion about the adequate degree of plurality. We instantiate the trade-off by showing how it originates from two main challenges: the need to derive adequate quality criteria for a pluralist economics, and the necessity to propose strategies that ensure the communication across different research programs. The paper concludes with some strategies to meet these challenges.
