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 principle of effective demand, and the claim of its validity for a monetary production economy in the short and in the long run, is the core of heterodox macroeconomics, as currently found in all the different strands of post-Keynesian economics (Fundamentalists, Kaleckians, Sraffians, Kaldorians, Institutionalists) and also in some strands of neo-Marxian economics, particularly in the monopoly capitalism and underconsumptionist school In this contribution, we will therefore outline the foundations of the principle of effective demand and its relationship with the respective notion of a capitalist or a monetary production economy in the works of Marx, Kalecki and Keynes. Then we will deal with heterodox short-run macroeconomics and it will provide a simple short-run model which is built on the principle of effective demand, as well as on distribution conflict between different social groups (or classes): rentiers, managers and workers. Finally, we will move to the long run and we will review the integration of the principle of effective demand into heterodox/post-Keynesian approaches towards distribution and growth.

This video by the Khan Academy presents the difference between monetary policy and fiscal policy and how they affect aggregate demand. The video especially elaborates on the basic explanation on how expansionary monetary policy increases aggregate demand via the market for money and the AD-AS model.

The short clip gives a basic introduction to the concept of the market equilibrium and its graphical representation: taking the example of a market for apples, it presents supply and demand curves as well as scenarios how prices and quantities adapt, leading to an equilibrium.

This journal article by Radhika Desai, Professor at the Department of Political Studies, and Director of the Geopolitical Economy Research Group at the University of Manitoba, Winnipeg, Canada, was originally published in 2010 and republished in an revised format in 2020. The article is a comprehensive treatment of Marx's theory of crisis, focusing on the role of consumption demand in capitalism and in the emergence of crises.

Usually, Critical Theory and Economics are, for better or worse, no longer seen to be in a continuum. This article by Lukas Meisner serves as an introduction to Critical Theory for all (heterodox) economists, who want to understand and explain what they can, otherwise, just state and describe.
Critical Theory for Heterodox Economists: Questioning the Premises of Supply and Demand
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.

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.

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?
Inflation in economic theory
For a long time, price controls were considered taboo, as neoliberal economic theory assumes that prices are supposedly formed freely by supply and demand. But especially in times of crisis, the state must intervene and cap prices to protect wage earners from excessive burdens. However, the how matters.
Price Controls Against Inflation
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.

Im AS-AD Gleichgewicht treffen die Gleichgewichtsbedingungen aller Märkte (Güter-, Geld-, Finanz- und Arbeitsmarkt) einer Volkswirtschaft zusammen. Das Gleichgewicht wird bestimmt durch die gesamtwirtschaftliche Nachfrage „aggregate demand“ und dem gesamtwirtschaftlichen Angebot „aggregate supply“ einer Volkswirtschaft.

In this keynote lecture during the conference „The Spectre of Stagnation? Europe in the World Economy“, Till van Treek presents research on how changes in income distribution lead to macroeconomic instability and crisis, focusing on currents accounts. Treek presents the relative income hypothesis in contrast to other mainstream and Post-Keynesian explanations. The relative income hypothesis proposes that aggregate demand increases and savings decrease with rising personal income inequality due to upward looking status comparison – but effects depend on the quantile where income inequality increases. Treek points to the importance of accounting for both income and functional income distribution and underlines his arguments with data comparing different pattern in Germany and the U.S.

Keen first compares neoclassical approaches to modelling with heterodox ones. Then he discusses in length the required assumptions and the inconsistencies of the aggregate demand and supply model, which is extrapolated from a micro perspective. At the end some dynamic models with feedback mechanisms are shown.
The Mainstream Obsession with Microfoundations and why it is an intellectual dead-end
Eckhard Hein criticises the mainstream's view of secular stagnation as the result of a negative real equilibrium interest rate. Arguing in a Keynesian spirit with particular reference to Steindl, secular stagnation is considered to be a result of shift in the functional income distribution, and oligopolistic organisation of industries, leading to excess capacity and reluctance to invest. This acts as a drag on effective demand and results in secular stagnation. Distributional policies and public investment can, however, overcome stagnation its tendencies.
Secular Stagnation or stagnation policy? Steindl after Summers
Özlem Onaran analyses the current problems of secular stagnation from a global perspective. At the core of global economic problems is insufficient demand caused by falling wage shares, because most individual countries, and the world as a whole are “wage-led”. Hence a strategy for global growth is to aim at increasing wages and thus the wage share, and the abandonment of policies focusing purely on national competitiveness. Financialization has broken the link between corporate profitability and investment. Reregulation of finance and higher public investment is required in order to crowd in private investment, in this way, reversing the declining trend of potential output growth.

An Introduction to the Political Theory of John Maynard Keynes. John Maynard Keynes was arguably the greatest economist of the 20th century. He discovered the idea that governments should stimulate demand during economic downturns.

The blog post by Marc Lavoie contrasts what he perceives as the two main interpretations of the current inflationary tendencies (the 'excessive demand inflation' story and the 'profit inflation' story) and contrasts them with a third interpretation. This interpretation acknowledes rising profits but argues in favor of a different mechanism that centers on changes in the relative composition of costs.

The Dichotomy, Inconsistency, and Peculiar Outmodedness of the "Mainstream" Textbook
The Great Recession 2.0 is unfolding before our very eyes. It is still in its early phase. But dynamics have been set in motion that are not easily stopped, or even slowed. If the virus effect were resolved by early summer—as some politicians wishfully believe—the economic dynamics set in motion would still continue. The US and global economies have been seriously ‘wounded’ and will not recover easily or soon. Those who believe it will be a ‘V-shape’ recovery are deluding themselves. Economists among them should know better but are among the most confused. They only need to look at historical parallels to convince themselves otherwise.
Origins & Emergence of the 2020 Great Recession in the US Economy
It is perhaps fitting that the seriousness of the coronavirus threat hit most of the Western world around the Ides of March, the traditional day of reckoning of outstanding debts in Ancient Rome. After all, problems and imbalances have accumulated in the Western capitalist system over four decades, ostensibly since it took the neoliberal road out of the 1970s crisis and kept going along it, heedless of the crises and problems it led to.
The Unexpected Reckoning: Coronavirus and Capitalism
Mainstream inflation theories in economics do little to explain the recent acceleration in price increases. The associated economic policy recommendations further increase the misery of low-income groups.
The inflation conundrum
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?
In parallel to rising inflation numbers, the concept of profit inflation has clearly risen to prominence in recent years. But what is it exactly? This dossier aims not only to collect the most important publications on profit inflation but also intends to map out the development of the discourse and the different positions within the debate.

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
The outbreak of COVID-19 has substantially accelerated the digitalization of the economy. Yet, this unprecedented growth of digital technology brought novel challenges to the labour market. Rise in income inequalities and precarious working conditions or polarization of jobs. In this essay, we try to assess what tools to use to counter these trends.
