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.
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.
By conducting a discourse analysis (SKAD) in the field of academic economics textbooks, this paper aims at reconstructing frames and identity options offered to undergraduate students relating to the questions ‘Why study economics?’ and ‘Who do I become by studying economics?’. The analysis showed three major frames and respective identity offerings, all of which are contextualized theoretically, with prominent reference to the Foucauldian reflection of the science of Political Economy. Surprisingly, none of them encourages the student to think critically, as could have been expected in a pedagogical context. Taken together, economics textbooks appear as a “total structure of actions brought to bear upon possible action” (Foucault), therefore, as a genuine example of Foucauldian power structures.
Homo Economicus: Why are new year’s resolutions so difficult to maintain and economic models so bad at predicting our behaviour?
Have you ever wondered why it is so difficult to follow through on new year’s resolutions, such as to exercise more or to start saving more money towards retirement? The agent that most traditional economic models are based on would not struggle to keep up these resolutions. These agents are referred to as homo economicus.
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.
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.
Based on a critique on econometric and DSGE models (in particular in the context of the financial crisis), Doyne Farmer presents his current research programme that aims at building an agent-based model of the financial and economic crisis. It models heterogeneous agents and from there simulates the economy, firstly for the housing market. The interview gives a short insight in the research programme.
In this radio interview, Philip Mirowski, author of the book "Never Let a Serious Crisis Go to Waste" presents several differences between neoclassical economics and neoliberalism. Apart from a historical outline, Mirowski primarily discusses different perceptions of markets and the role of the state. Mirowski further reflects on the role think tanks ("part of the "neoliberal thought collective") and the entrepreneurial self (the "neoliberal agent") in the spreading and fostering of the neoliberalism.
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.
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.
Dependency in Central and Eastern Europe - Self-reliance and the need to move beyond economic growth
In this essay, the author takes a critical perspective on the pursuit of growth as the solution for providing for environmental sustainability and economic stability in the countries of Central and Eastern Europe. Drawing from the framework of dependency theory and presenting brief insights into European core-periphery relations the author then argues for the implementation of an alternative strategy to development that is built around the concept of self-reliance.
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.
The module is designed to first present some of the main schools of thought from a historical and methodological perspective. Each week we explore and critically assess the main tenants of each school of thought. In the second part of the module we link history of economic thought and methodology to a specific and contemporary economic question. The second part allows you to engage with current economic issues with an awareness of methodology and methodological differences and with some knowledge of the history of economics.
The article pursues the two related questions of how economists pretend to know and why they want to know at all. It is argued that both the economic form of knowledge and the motivation of knowing have undergone a fundamental change during the course of the 20th century. The knowledge of important contemporary economic textbooks has little in common with an objective, decidedly scientifically motivated knowledge. Rather, their contents and forms follow a productive end, aiming at the subjectivity of their readers.
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.
Approaching the law of nature that determines all forms of economy. The bulk of economic theory addresses the economic process by setting out on a catalogue of aspects, seeking the laws in the aspects and hoping to get together a reliable view of the whole.
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?
A historical glimpse of how economists of the 19th century debated the usefulness of mathematics to economics
Behavioural economics deals with observing behaviour and economic decision making behaviour.
The objective of the course is to explore the main strengths and weaknesses of orthodox and heterodox paradigms within development economics.
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.
Feminist economics focuses on the interdependencies of gender relations and the economy. Care work and the partly non-market mediated reproduction sphere are particularly emphasised by feminist economics.
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.
This syllabus provides an overview of the contents of the course "Understanding Economic Models" at the University of Helsinki.
The novel coronavirus (Covid-19) is rapidly spreading around the world. The real economy is simultaneously hit by a supply shock and a demand shock by the spread of coronavirus. Such a twin shock is a rare phenomenon in recent economic history.
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.
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 lecture was held in the context of the a two day conference called Which pluralism for thinking about how to achieve a more sustainable and resilient economy The practices institutions and system logics of today s economy are not suitable for appropriately addressing fundamental human needs The climate crisis …
With the onset of an economic crisis that has been universally acknowledged since the end of March, two main questions arise: To what extent is the corona pandemic the starting point (or even the cause) of this crisis? And secondly: can the aid programmes that have been adopted prevent a deep and prolonged recession?
In this essay, the principle of capital accumulation, as well as the idea of homo economicus as the basis of the growth model, are located and analyzed from a feminist perspective. The sufficiency approach is presented as an alternative to these two economic logics.
