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.

Présentation générale des enjeux et objets d'étude d'une approche féministe de l'économie.

Dans cet épisode, nous nous posons la question du rôle de la monnaie dans une économie capitaliste. Pour cela, nous comparons le fonctionnement de deux économies en apparence identique, à ceci près que la première fonctionne sans monnaie, comme une économie de troc, et la seconde est monétaire. Nous nous apercevons alors que le caractère monétaire ou non d’une économie modifie radicalement ses propriétés. La détermination des profits sera ainsi très différente dans ces deux économies, les relations de causalité entre dépôts et crédits, épargne et investissement s’inversent, une crise de surproduction est possible dans un cas mais pas dans l’autre, et le chômage peut également avoir des origines très différentes, et même opposées, selon que l’on considère une économie monétaire ou non. Les propriétés de l’économie de troc recouvrent celles de la théorie économique standard (théorie néoclassique) qui s’est historiquement construite sans prendre en considération la monnaie, celle-ci étant considérée comme neutre sur l’économie. Les propriétés de l’économie monétaire rappellent quant à elles celles des modèles postkeynésiens, bien moins connus, et qui trouvent leurs origines dans les travaux et écrits de Keynes, qui affirmait dans son ouvrage le plus célèbre (la théorie générale de l’emploi de l’intérêt et de la monnaie) que « lorsqu’on s’attaque à la recherche des facteurs qui déterminent les volumes globaux de la production et de l’emploi, la Théorie complète d’une Economie Monétaire devient indispensable » (1936, p. 297). Pour approfondir le fonctionnement d’une économie monétaire, vous pouvez lire le livre de Laurent Cordonnier, maître de conférences à l’Université de Lille, « L’économie des Toambapiks » qui présente à partir d’une « fable » la loi des profits de Kalecki dont nous parlons dans la vidéo. Le livre se lit très facilement.

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.

Constatant la complexité de ses vidéos récentes, le youtubeur Heu?reka décide de faire un recapitulatif du "fonctionnement de l'économie, le PIB, les marchés financiers, les traders, les différentes banques, l'Etat, la création monétaire et la dette."

David Harvey illustrates the five most common narratives on why the financial and economic crisis took place – from human frailty to policy failure.

Markets are the focus in modern economics: when they work, when they don’t and what we can or can’t do about it. There are many ways to study markets and how we do so will inevitably affect our conclusions about them, including policy recommendations which can influence governments and other major organisations. Pluralism can be a vital corrective to enacting real policies based on only one perspective and a plethora of approaches provide alternatives to the canonical view. Although they have differing implications, these approaches share the idea that we should take a historical approach, analysing markets on a case-by-case basis; and they share a faith in the power of both individuals and collectives to overcome the problems encountered when organising economic activity.

Firms are the primary places where economic activity takes place in modern capitalist economies: they are where most stuff is produced; where many of us spend 40 hours a week; and where big decisions are made about how to allocate resources. Establishing how they work is hugely important because it helps us to understand patterns of production and consumption, including how firms will react to changes in economic conditions and policy. And a well-established literature – led by post-Keynesians and institutionalists – holds that the best way to determine how firms work is to…wait for it...ask firms how they work. This a clearly sensible proposition that is contested in economics for some reason, but we’ll ignore the controversy here and just explore the theory that springs from this approach.

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.

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.

In the inspiring interview on Economics of Care, Nancy Foblre takes a closer look to the consequences of the marketization of caring activities on those activities and on the societal organization of care. Folbre elaborates on how to value care and how this shifts the perspectives on living standards. She points to the fact, that caring activities are undervalued both in the market sphere and within the family and thereby questions the division between those spheres. Lastly, Folbre answers the question how to reteach Economics when accounting for caring activities.

Dans cet interview Roger Guesnerie, titulaire de la chaire "Théorie Économique et Organisation Sociale" au Collège de France, donne un point de vue d'économiste néoclassique sur la pertinence de sa propre perspective.

In this article, Gareth Dale analyzes and compares the main characteristics and differences of two visions that are currently emerging to tackle Climate Change: the Green New Deal and Degrowth. Which are the consequences from the environmental, economic and political point of view? And what are the underlying doctrines?

In this podcast, Amy Goodman and Juan González explore together with Joseph Stiglitz, a Nobel Prize-winning economist, inequality and the state of the U.S. economy. Topics they touch upon are capitalism, taxation, powerlessness of citizens and Joseph Stiglitz's book entitled People, Power, and Profits: Progressive Capitalism for an Age of Discontent.

What influence do changes in tax policy or state decisions on expenditure have on economic growth? For decades, this question has been controversially debated.

The most successful multialternative theories of decision making assume that people consider individual aspects of a choice and proceed via a process of elimination. Amos Tversky was one of the pioneers of this field, but modern decision theorists – most notably Neil Stewart – have moved things forward. At the current stage the theories are able to explain a number of strictly ‘irrational’ but reasonable quirks of human decision making, including various heuristics and biases. Not only this, but eye movements of participants strongly imply that the decision-making process depicted in the theories is an accurate one.

Nathan Tankus created this series to introduce people outside of the inner financial circles of professionals, journalists and policymakers to the basic mechanisms and dynamics of monetary policy.

In this podcast, Laura Basu focuses on how capitalist markets and nation-states perpetuate structural racism.

Fighting Neoliberalism with Keynes & Minsky? Riccardo Bellofiore proposes to revise the insights of Minsky's financial instability hypothesis, combining it with the Keynesian theory of the monetary circuit to answer many questions in modern economy.

In both economics textbooks and public perceptions central banks are a fact of life. On the wall of my A-level economics classroom there was the Will Rogers quote “there have been three great inventions since the beginning of time: fire, the wheel, and central banking”, summarising how many economists view the institution. There is a widespread belief that there is something different about money which calls for a central authority to manage its operation, a view shared even by staunch free marketeers such as Milton Friedman. This belief is not without justification, since money underpins every transaction in a way that apples do not, but we should always be careful not to take existing institutions for granted and central banking is no exception. In this post I will look at the idea of private or free banking, where banks compete (and cooperate) to issue their own currency.

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.

The need for the movement Black Lives Matter and the tragic events that preceded it are the clear manifestation of the problem of discrimination today, which we all intuitively perceive as a poignant socio-economic question of our times.

The historian Nicholas Mulder talks about the Western sanctions against Russia in the context of the Ukraine Crisis. He explains that the current sanctions are unprecedented in terms of size, speed and scope, expected consequences as well as potential drawbacks and problems.
