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 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.
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.
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.
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.
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.
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.
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.
This book arose from our conviction that the NNS-DSGE approach to the analysis of aggregate market outcomes is fundamentally flawed. The practice of overcoming the SMD result by recurring to a fictitious RA leads to insurmountable methodological problems and lies at the root of DSGE models’ failure to satisfactorily explain real world features.
Esther Duflo discusses the fact that in social policy one cannot check the big questions, i.e. whether development assistance as an aggregate is helpful, because there is no counterfactual. She then suggests to focus on smaller questions such as what prevents or incentiveses people from immunizing their kids or whether mosquito bednets should be distributed for free. These questions can be answered by using randomized control trials as in the medical sciences. Thus, she argues, by bringing the experimental method to social policy analysis better decisions as to where allocate funds can be made.
In diesem Workshop zeigt Christian Proaño die Kritik an der Neuen Neoklassischen Synthese aus Sicht der Behavioral Macroeconomics. Für Fortgeschrittene gibt er einen Einblick in Behavioral Macroeconomics und zeigt Modelle mit heterogenen Erwartungen (De Grauwe 2012), den Aggregate Sentiments Approach (Franke 2012) sowie den Learning Aproach (nach Evans, Honkapohja 2001). Kritiker könnten der Behavioral Macroeconomics Forschung vorwerfen, dass sie im Grunde Neoklassische Konzepte repariert, das wissenschaftstheoretische Fundament aber nie verlässt und sich damit selbst begrenzt. Die Folien des Vortrags sind hier verfügbar: http://www.boeckler.de/pdf/v_2016_08_12_proano_slides.pdf
Making sense of economists and their world in a persuasive and entertaining style, Arjo Klamer, shows that economics is as much about how people interact as it is about the models, the mathematics, the econometrics, the theories and the ideas that come from the enormous aggregate of economics literature. Knowing and understanding economics requires both bookwork and mingling with other economists.
In a capitalist system, consumers, investors, and corporations orient their activities toward a future that contains opportunities and risks. How actors assess uncertainty is a problem that economists have tried to solve through general equilibrium and rational expectations theory. Powerful as these analytical tools are, they underestimate the future's unknowability by assuming that markets, in the aggregate, correctly forecast what is to come.
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.
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.
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.
This course provides an introduction into the basic concepts of mainstream macroeconomics, including supply and demand in a competitive market, to all the usual introductory macroeconomic topics, and also to both international trade and the Foreign Exchange Market.
Designed for both undergraduates and MBA students taking their first course in business economics, this text focuses on introducing students to economics as a framework for understanding business. It is structured around problems that decision-makers face, such as rejuvenating the firm in the face of declining demand.
Forecasting is required in many situations. Stocking an inventory may require forecasts of demand months in advance.
To prevent the coronavirus shock to demand precipitating a long-lasting depression, government needs to become short-term payer of last resort.
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?

Neoclassical economics focuses on the allocation of scarce resources. Economic analysis is mainly concerned with determining the efficient allocation of resources in order to increase welfare.
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 goal of the class is to acquire familiarity with recently-published research in alternative macroeconomics with a focus on the distribution of income and wealth, cyclical growth models, and technical change.
What made the false assumption that saving the economy at all cost during a pandemic so popular? This paper discusses different pathways through the COVID-19 pandemic at national and international level, and their consequences on the health of citizens and their economies.
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.
Complexity economics focuses on interactions and interdependencies between individuals and structures in economic systems. Those are systems of organised complexity. High importance is given to the analysis of networks.
Der Fokus der Komplexitätsökonomik liegt auf den Interaktionen und Wechselwirkungen zwischen Individuen und Strukturen wirtschaftlicher Systeme. Diese werden als Systeme organisierter Komplexität aufgefasst. Ein besonderes Augenmerk liegt auf der Analyse von Netzwerken.
