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
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.

Political Economy based on Marx
One hundred years ago the idea of 'the economy' didn't exist. Now, improving the economy has come to be seen as perhaps the most important task facing modern societies. Politics and policymaking are conducted in the language of economics and economic logic shapes how political issues are thought about and addressed.
The Econocracy
Modern Monetary Theory (MMT) is a school of monetary and macroeconomic thought that focuses on the analysis of the monetary and credit system, and in particular on the question of credit creation by the state.

This course will fundamentally ask whether we can, or even should use the word ‘decolonising’ in our pursuit of a better economics?
Decolonising Economics?
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
Capitalism is dissolving boundaries - not only in the sense of ever-expanding global trade flows, but also in the concrete everyday working lives of individuals. What implications does this have for our understanding of freedom, work and borders?
Capitalism & Boundaries
Understanding international trade is central to economics and is currently a hot political issue. It’s an area where popular perceptions of mainstream economics are low, since they have historically missed some important downsides of trade agreements, especially the hollowing out of former manufacturing hubs in the Western world. et economists have for long time had a theory of trade with an impressive amount of scientific clout behind it: the gravity trade model.
A Theory of Enormous Gravity
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.
GDP Growth: It’s Complicated
This lecture by Economy Studies lays out the foundations and current state of the ecological crisis, its main drivers and who is responsible for this. It is crucial for students to develop a deeper understanding of the problem they are likely to encounter in their future careers, before getting into various economic policies or solutions to this pressing issue.

Economic sociology is an entire subfield and one could write an series on it, so I’m going to stick to probably the most prominent economic sociologist and the founder of ‘new economic sociology’, Mark Granovetter.

Feminist economics critically analyzes both economic theory and economic life through the lens of gender, and advocates various forms of feminist economic transformation. In this course, we will explore this exciting and self-consciously political and transformative field.
Feminist Economics
Along with addressing core conceptual issues in defining heterodox economics, we will cover in some detail five heterodox traditions in economics: Marxian Economics, Institutional Economics, Post-Keynesian Economics, Feminist Economics, and Ecologi-cal Economics. In the first class meeting, we discuss the structure and goals of the course, as well as the expectations and requirements from the students. In addition, we will discuss the concept of heterodoxy in economics, along with discussing the concepts and key issues in mainstream and neoclassical economics.
Heterodox Economics
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.

The term "de-risking" can be seen as one element of a strategy aimed at discursively reframing the trade policy confrontation with China. This confrontation has mainly been driven by the US in recent years and received initially cautious, but later growing support from the EU.

Pluralist Economic Analysis
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.

Commons stand for a plurality of practices ‘beyond market and state’ as the famous Commons scholar – and first female noble prize winner of economics - Elinor Ostrom put it. Their practice and theory challenge classical economic theory and stand for a different mode of caring, producing and governing. Within this workshop we want to dive into theory, practice and utopia of Commons following four blocks...
The Future of Commons
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?

Marx’s theory of the falling rate of profit is not only empirically borne out, but the theory he proposed seems to describe accurately how that happens. Furthermore, the whole process is useful for understanding the history of contemporary capitalism.

After completing the module, participants should be able to understand the economic consequences of gender inequality. They should be able to explain the contradictions between capital and care, analyze the labor market with a gender perspective and develop the ability to describe phenomena such as public policies taking into account "gender" as a category of analysis.

How long the COVID-19 crisis will last, and what its immediate economic costs will be, is anyone's guess. But even if the pandemic's economic impact is contained, it may have already set the stage for a debt meltdown long in the making, starting in many of the Asian emerging and developing economies on the front lines of the outbreak.
