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.

One of the most authoritative authors on the intellectual heritage of John Maynard Keynes, Robert Skidelsky draws a sketch of the great man's economic thinking both accessible and insightful.
Keynes: A Very Short Introduction
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 author identifies three principal economic phenomena, which are explained: long run productivity growth as the central driver of increasing economic activity, short-term and long-term debt cycles. The latter two are explained to some detailed with reference to money creation, central banking and long term crisis tendencies. With regards to the long run debt cycle, which leads into deleveraging and recession, some policy measures which can smoothen the crisis are discussed.

In this paper the main developments in post-Keynesian macroeconomics since the mid- 1990s will be reviewed. For this purpose the main differences between heterodox economics in general, including post-Keynesian economics, and orthodox economics will be reiterated and an overview over the strands of post-Keynesian economics, their commonalities and developments since the 1930s will be outlined. This will provide the grounds for touching upon three important areas of development and progress of post-Keynesian macroeconomics since the mid-1990s: first, the integration of distribution issues and distributional conflict into short- and long-run macroeconomics, both in theoretical and in empirical/applied works; second, the integrated analysis of money, finance and macroeconomics and its application to changing institutional and historical circumstances, like the process of financialisation; and third, the development of full-blown macroeconomic models, providing alternatives to the mainstream 'New Consensus Model' (NCM), and allowing to derive a full macroeconomic policy mix as a more convincing alternative to the one implied and proposed by the mainstream NCM, which has desperately failed in the face of the recent crises.
Post-Keynesian macroeconomics since the mid-1990s: Main developments
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
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 economist Thomas Piketty presents a central argument of his book Capital in the Twenty-First century: if the rate of return to capital generally exceeds an economy's growth rate, this leads to a higher concentration of wealth in the long run. He furthermore shows with historical data how wealth and income inequality increased within the past decades.

The world is coping with a global disaster, as the new Coronavirus takes a toll on many lost lives and a severe impact on economic activity. To provide a long-run perspective, this column documents the international response to a variety of disasters since 1790. Based on a new comprehensive database on loans extended by governments and central banks, official (sovereign-to-sovereign) international lending is much larger than generally known. Official lending spikes in times of global turmoil, such as wars, financial crises or natural disasters. Indeed, in these periods, official capital flows have repeatedly surpassed total private capital flows in the past two centuries. Wars, in particular, were accompanied by large surges in the volume of official cross-border lending.
Coping with disasters: Lessons from two centuries of international response
Some economic events are so major and unsettling that they “change everything.” Such is the case with the financial crisis that started in the summer of 2007 and is still a drag on the world economy. Yet enough time has now elapsed for economists to consider questions that run deeper than the usual focus on the immediate causes and consequences of the crisis.
Rethinking the Financial Crisis
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.

The short statements in the video also reflect other possibilities of transformation.
Green Economy and Sustainable Development: Bringing Back the Social
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.

Recovery from the Covid-19 crisis provides a chance to implement economic measures that are also beneficial from environmental and social perspectives. While ‘green’ recovery packages are crucial to support economies tracking a low-carbon transition in the short-term, green measures such as carbon pricing are also key to improving welfare in the long-term. This commentary specifies the need for carbon pricing, outlines its implications for our everyday lives, and explains how it works alongside value-based change in the context of climate action and societal well-being.

Philosopher and political economist John Stuart Mill laid several foundations for liberal thinking, amongst others with the harm principle: everyone should be given the individual freedom - and not be hindered by e.g. state intervention - to act as s/he wants as long as no other person is harmed by this action. A short insight in his book On Liberty.

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.
