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 video presents different ways of how to measure the money supply and thereby explains the differences between M0, M1 and M2.
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 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.
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.
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 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.
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.
Jihen Chandoul, a member of the Post-Colonialisms Today Working Group, discusses the impact of import-dependency on African food supply chains since the onset of the COVID-19 pandemic.

John K. Galbraith recounts episodes in the history of money such as the creation of the bank of Amsterdam, John Law's fraudulent Bank Royal, the inception of the Bank of England and of the Federal Reserve to illustrate concepts such as money creation by commercial banks, the bank rate, open market operations or the money supply in general. The emotions, myths and struggles surrounding money are addressed and explained in a clear and consistent manner.
Modern authors have identified a variety of striking economic patterns, most importantly those involving the distribution of incomes and profit rates. In recent times, the econophysics literature has demonstrated that bottom incomes follow an exponential distribution, top incomes follow a Pareto, profit rates display a tent-shaped distribution. This paper is concerned with the theory underlying various explanations of these phenomena. Traditional econophysics relies on energy-conserving “particle collision” models in which simulation is often used to derive a stationary distribution. Those in the Jaynesian tradition rely on entropy maximization, subject to certain constraints, to infer the final distribution. This paper argues that economic phenomena should be derived as results of explicit economic processes. For instance, the entry and exit process motivated by supply decisions of firms underlies the drift-diffusion form of wage, interest and profit rates arbitrage. These processes give rise to stationary distributions that turn out to be also entropy maximizing. In arbitrage approach, entropy maximization is a result. In the Jaynesian approaches, entropy maximization is the means.
Jason Smith takes a stab at blind faith in the efficiency of the price mechanism to provide market information. To do so, he calls upon Information Theory and Generative Adversarial Networks to argue the price mechanism is faulty and skewed towards supply.
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.
"The New Classical Macroeconomics "gives an accessible, rigorous, critical account of the central doctrines of the new classical economics, without unnecessarily difficult mathematics. It focuses on four central issues: the foundation of monetary theory; monetary and fiscal policy; labour supply and business cycles; and the attack on econometric 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?
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.

A central question in development economics literature is, “Why do countries stay poor?” The key disagreements are whether the lack of economic growth stems from institutions or from geography (Nunn 2009). From an institutional perspective, hostile tariff regimes and commodity price dependencies form a barrier to a sectoral shift that would otherwise lead to economic development in developing countries (Blink and Dorton 2011) (Stiglitz 2006).[i]
What influence do changes in tax policy or state decisions on expenditure have on economic growth? For decades, this question has been controversially debated.
