Antoine Godin gives a bright, illustrated, introduction to agent-based, stock-flow-consistent modeling, with a clear focus on the agent-based aspect.
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.
One method of economic modelling that has become increasingly popular in academia, government and the private sector is Agent Based Models, or ABM. These simulate the actions and interactions of thousands or even millions of people to try to understand the economy – for this reason ABM was once described to me as being “like Sim City without the graphics”. One advantage of ABM is that it is flexible, since you can choose how many agents there are (an agent just means some kind of 'economic decision maker' like a firm, consumer, worker or government); how they behave (do they use complicated or simple rules to make decisions?); as well as the environment they act in, then just run the simulation and see what happens as they interact over time.
Keen first compares neoclassical approaches to modelling with heterodox ones. Then he discusses in length the required assumptions and the inconsistencies of the aggregate demand and supply model, which is extrapolated from a micro perspective. At the end some dynamic models with feedback mechanisms are shown.
In this blog article Steve Keen elaborates on flawed climate change modelling and mainstream economics forecasts. In specific, he stresses the climate change forecasts of the DICE model (“Dynamic Integrated model of Climate and the Economy”) by Nobel Memorial Prize in Economic Sciences winner William Nordhaus.
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.
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.
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.
Steve Keen analyses how mainstream economics fails when confronted with the covid-19-pandemic. Mainstream economics has propagated the dismantling of the state and the globalization of production - both of which make the crisis now so devastating. More fundamentally, mainstream economics deals with market systems, when what is needed to limit the virus’s spread is a command system.
This lecture course, which will be taught in English, will deal with gender issues in developing countries. After providing an overview of the gender differences in various aspects of welfare and economic life, the course will then tackle a number of specific issues.
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.

Neoclassical economics focuses on the allocation of scarce resources. Economic analysis is mainly concerned with determining the efficient allocation of resources in order to increase welfare.
As opposed to the conventional over-simplified assumption of self-interested individuals, strong evidence points towards the presence of heterogeneous other-regarding preferences in agents. Incorporating social preferences – specifically, trust and reciprocity - and recognizing the non-constancy of these preferences across individuals can help models better represent the reality.
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.

This essay deals with the concepts of Sustainable Land Management (SLM) and Land Degradation Neutrality (LDN).
Hannes Vetter hat sich in Rahmen der Schreibwerkstatt "Varieties of Mainstream Economics?" mit der Evaluation der Bewertung von Umwelt in neoklassischen Makromodellen auseinandergesetzt.
Maria Nikolaidi on how Minsky’s theory has been modelled over past decades and how one can use these models in order to analyse contemporary issues such as financial fragility and financial instability caused by climate change.
Um der Klimakrise zu begegnen, müssen wir unsere Art zu wirtschaften radikal verändern. Ein großes Hindernis auf diesem Weg könnte die vorherrschende ökonomische Theorie sein. Denn der neoklassischen Wirtschaftswissenschaft ist es methodisch unmöglich, alternative Wirtschaftsformen abzubilden. Außerdem führt sie zu Politikempfehlungen, die systematisch die Möglichkeit einer Postwachstumswirtschaft ausblenden.
Exploring Economics, an open-source e-learning platform, giving you the opportunity to discover & study a variety of economic theories, topics, and methods.
Michael Kalecki famously remarked “I have found out what economics is; it is the science of confusing stocks with flows”. Stock-Flow Consistent (SFC) models were developed precisely to address this kind of confusion. The basic intuition of SFC models is that the economy is built up as a set of intersecting balance sheets, where transactions between entities are called flows and the value of the assets/liabilities they hold are called stocks. Wages are a flow; bank deposits are a stock, and confusing the two directly is a category error. In this edition of the pluralist showcase I will first describe the logic of SFC models – which is worth exploring in depth – before discussing empirical calibration and applications of the models. Warning that there is a little more maths in this post than usual (i.e. some), but you should be able to skip those parts and still easily get the picture.
One of the pluralist theories which has gained prominence following the 2008 financial crisis is Hyman Minsky and his Financial Instability Hypothesis (FIH). Minsky was unique in viewing balance sheets and financial flows as the primary components of capitalist economies, and his focus on the financial system meant he was well-equipped for foresee a crisis much like 2008. Although he died long before 2008 his framework anticipated many of the processes which led to the crash, particularly increased risk-taking and financial innovation which would outstrip the abilities of regulators and central banks to manage the system.

A stock-flow-fund ecological macroeconomic model
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.
The global financial crisis (GFC) led to increasing distrust in economic research and the economics profession, in the process of which the current state of economics and economic education in particular were heavily criticized. Against this background we conducted a study with undergraduate students of economics in order to capture their view of economic education.
What’s inflation? Why is it relevant? And is there an agreed theory about its roots and causes, or is it a contentious concept? That’s what this text is all about: We define what inflation actually means before we delve into the theoretical debate with an interdisciplinary and pluralist approach: What gives rise to it, what factors might influence it, and, consequently, what might be done about it?
