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.
Stock Flow Consistent Macroeconomics
Chercheuse au CNRS, Lauriane Mouysset s'attaque au défi de concilier économie et écologie pour concevoir un développement durable.
Pas si simple de faire un choix, lorsqu’il s’agit de penser en amont, à tous les avantages mais aussi aux conséquences qui vont en découler. Peut-être que la clé de tout choix se trouve sur les valeurs fondamentales, celles qui font nos sociétés.
Lauriane nous invite à réfléchir à la meilleure façon d’agir et de faire un bon choix face à la crise écologique.

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.
The Economics of Care
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.
Markets, How Do They Work?
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.
The ‘How Firms Work’ Approach to How Firms Work
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.

What influence do changes in tax policy or state decisions on expenditure have on economic growth? For decades, this question has been controversially debated.
What is the fiscal multiplier and why is it so controversial?
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.

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.

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.
Economics of Discrimination - A CBD Perspective
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.

In the history of the social sciences, few individuals have exerted as much influence as has Jeremy Bentham. His attempt to become “the Newton of morals” has left a marked impression upon the methodology and form of analysis that social sciences like economics and political science have chosen as modus operandi.

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"
IS-LM is perhaps the prime example of `cognitive dissonance' in economics, and is problematic to many economists. On the one hand, the IS-LM model is still taught by many academic economists or they use it to derive the AD-AS approach. On the other hand, the same economists realize the limitations of the basic IS-LM model and would not now use it for policy analysis, as they did in the past. The distinction between pedagogical and analytical efficacy is made by all the authors in this volume regarding the IS-LM model.
