What do modern academic economists do? What currently is mainstream economics? What is neoclassical economics? And how about heterodox economics? How do the central concerns of modern economists, whatever their associations or allegiances, relate to those traditionally taken up in the discipline?
Essays on the Nature and State of Modern Economics
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.
Post-Keynesian Economics
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.
A fresh perspective to economic theory: Social preferences and their impact on gender and policy
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.
Agents, agents everywhere
The notion that the demand and supply side are independent is a key feature of textbook undergraduate economics and of modern macroeconomic models. Economic output is thought to be constrained by the productive capabilities of the economy - the ‘supply-side' - through technology, demographics and capital investment. In the short run a boost in demand may increase GDP and employment due to frictions such as sticky wages, but over the long-term successive rises in demand without corresponding improvements on the supply side can only create inflation as the economy reaches capacity. In this post I will explore the alternative idea of demand-led growth, where an increase in demand can translate into long-run supply side gains. This theory is most commonly associated with post-Keynesian economics, though it has been increasingly recognised in the mainstream literature.
It’s Demand All the Way Down
The new online platform ‚DIY Macroeconomic Model Simulation‘ provides an open-source code repository and online script for macroeconomic model simulation. It follows a “do-it-yourself” (DIY) approach, empowering users to numerically simulate key macroeconomic models on their own using the programming language R.

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.
Pluralism in economics: its critiques and their lessons
How do people make decisions? There is a class of models in psychology which seek to answer this question but have received scant attention in economics despite some clear empirical successes. In a previous post I discussed one of these, Decision by Sampling, and this post will look at another: the so-called Fast and Frugal heuristics pioneered by the German psychologist Gerd Gigerenzer. Here the individual seeks out sufficient information to make a reasonable decision. They are ‘fast’ because they do not require massive computational effort to make a decision so can be done in seconds, and they are ‘frugal’ because they use as little information as possible to make the decision effectively.
Bounded Rationality: the Case of ‘Fast and Frugal’ Heuristics
If there’s one method economists have neglected the most, it’s qualitative research. Whereas economists favour mathematical models and statistics, qualitative research seeks to understand the world through intensive investigation of particular circumstances, which usually entails interviewing people directly about their experiences. While this may sound simple to quantitative types the style, purpose, context, and interpretation of an interview can vary widely. Because of this variety, I have written a longer post than usual on this topic rather than doing it a disservice. Having said that, examples of qualitative research in economics are sadly scant enough that it doesn’t warrant multiple posts. In this post I will introduce qualitative research in general with nods to several applications including the study of firm behaviour, race, Austrian economics, and health economics. More than usual I will utilise block quotes, which I feel is in the spirit of the topic.
Qualitative Methods in Economics: "You Can Observe a Lot Just by Watching"
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.

What data is used in the economic models of the IPCC? How problematic is it, that tipping points are often ignored? A very interesting presentation by Steve Keen during the OECD Conference "Averting Systemic Collapse".
Averting Systemic Collapse
Adam Smith's The Wealth of Nations provided the first, most influential and lasting explanation of the workings of modern economics. But with his focus on "the market" as the best mechanism for producing and distributing the necessities of life, Smith's concepts only told part of the story, leading to flawed economic models that devalue activities that fall outside of the market's parameters of buying and selling.
The Real Wealth of Nations
The models of portfolio selection and asset price dynamics in this volume seek to explain the market dynamics of asset prices. Presenting a range of analytical, empirical, and numerical techniques as well as several different modeling approaches, the authors depict the state of debate on the market selection hypothesis.

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.
Introduction to Complexity
This is the first intermediate microeconomics textbook to offer both a theoretical and real-world grounding in the subject. Relying on simple algebraic equations, and developed over years of classroom testing, it covers factually oriented models in addition to the neoclassical paradigm, and goes beyond theoretical analysis to consider practical realities.
Intermediate Microeconomics
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.
Beyond Equilibrium and Efficiency
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.
Complex Economics
This book tells the story of the search for disequilibrium micro-foundations for macroeconomic theory, from the disequilibrium theories of Patinkin, Clower and Leijonhufvud to recent dynamic stochastic general equilibrium models with imperfect competition.
Transforming Modern Macroeconomics
Derek Neal writes that economists must analyze public education policy in the same way they analyze other procurement problems. He shows how standard tools from economics research speak directly to issues in education. For mastering the models and tools that economists of education should use in their work, there is no better resource available.--
Information, Incentives, and Education Policy
Economics should schematically explain the key elements and main strands of this core part of social life: the actual workings of our economies. This book argues that orthodox, modern neoclassical economics does not fulfil this core task. Standard economics models do not address the real functioning of our market economies, but rather an imagined economy.
Economics and the Real World
Renowned scholars elaborate a critique on neoclassical economics and how it was unable to predict and even favoured the financial crisis. They refer to DSGE models, equilibrium theory and rational agents – a brief insight in the critique on neoclassic economics.

Banking 101 is a series of 6 short videos that ask the following questions: How do banks work and how is money created? Is reveals common misunderstandings of money creation and the role of banks. Furthermore, the videos show how models taught in many introductory classes to economics (Econ 101) do not reflect those processes:
Part 1) “Misconceptions around Banking” questions common comprehensions of how banks work (savings = investments).
Part 2) “What's wrong with the money multiplier” states that the model of the money multiplies is inaccurate.
Part 3) “How is money really made by banks” explains the process of money creation, loans and inter-bank settlement.
Part 4) “How much money banks create?” asks what limits the money creation by banks and presents the difference between reserve ratio, liquidity ration, equity and refers to the inter-bank market.
Part 5) Explores the question if banks create money or just credit and especially refers to credit risks.
Part 6) Explains how money gets destroyed when loans are paid back.
Note: The videos refer to the UK monetary and banking system, some explanations don't apply to other banking systems, e.g. the reserve ratio.

What's wrong with the money multiplier? - Banking 101 (Part 2 of 6)
This short video by the Khan Academy presents a classic introduction to economic teaching. Starting with the quote by Adam Smith in "The Wealth of Nations" on the invisible hand, it shows how economics deals with the question of the allocation of scarce resources and shortly presents different questions addressed by microeconomics and macroeconomics. It further makes reference to questions of simplification in mathematical models.

This paper presents an overview of different models which explain financial crises, with the aim of understanding economic developments during and possibly after the Great Recession. In the first part approaches based on efficient markets and rational expectations hypotheses are analyzed, which however do not give any explanation for the occurrence of financial crises and thus cannot suggest any remedies for the present situation. A broad range of theoretical approaches analyzing financial crises from a medium term perspective is then discussed. Within this group we focused on the insights of Marx, Schumpeter, Wicksell, Hayek, Fisher, Keynes, Minsky, and Kindleberger. Subsequently the contributions of the Regulation School, the approach of Social Structures of Accumulation and Post-Keynesian approach, which focus on long-term developments and regime shifts in capitalist development, are presented. International approaches to finance and financial crises are integrated into the analyses. We address the issue of relevance of all these theories for the present crisis and draw some policy implications. The paper has the aim to find out to which extent the different approaches are able to explain the Great Recession, what visions they develop about future development of capitalism and to which extent these different approaches can be synthesized.
