Die enorm innovationsstarke deutsche Industrie ist in der Lage, viele der für die Erreichung von Klimaneutralität benötigten technischen Lösungen zu entwickeln und auf den Markt zu bringen. Dies ist jedoch kein Selbstläufer, sondern erfordert auch ein langfristiges Engagement der öffentlichen Hand. Ein Beitrag von Jan-Erik Thie und Benjamin Görlach.
Wie der klimaneutrale Umbau des Industriestandorts Deutschland gelingen kann
Die scheinbare Eindeutigkeit der wirtschaftswissenschaftlichen Analyse von Maßnahmen gaukelt eine Berechenbarkeit vor, die nichts mit der Realität zu tun hat. Vielmehr braucht es gerade in der Klimapolitik einen Ansatz, der flexibel reagieren kann und gleichzeitig die Entwicklung neuer innovativer Lösungen befördert: das sogenannte agile Politikdesign.
Warum wir eine agile Klimapolitik brauchen
Der Begriff „Subsistenz“ steht in seiner ursprünglichen Bedeutung für das „Bestehen aus sich selbst heraus“ bzw. Selbsterhaltung. Dies bildet den Bedeutungskern ganz unterschiedlicher Vorstellungen von „Subsistenz“ in der Fachliteratur (z. B. im Bielefelder Subsistenzansatz). Entgegen der üblichen Darstellungen soll „Subsistenz“ aber nicht z. B. auf Landwirtschaft, karges Leben oder feministische Aspekte reduziert sein, sondern für ganz unterschiedliche Wirtschaftsstile fruchtbar werden. Der modernen Subsistenzperspektive geht es vielmehr darum, Selbsterhaltung ganz allgemein als ein Grundmotiv des Wirtschaftens im theoretischen und praktischen (normativen) Rechtfertigungskontext zu thematisieren. Dafür sind aber begriffliche Spezifikationen notwendig.
Ökonomik ohne Existenznotwendigkeit?
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.
What's wrong with the money multiplier? - Banking 101 (Part 2 of 6)
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.

The sum of squares and degree of freedom calculation from the previous videos are put into a ratio to calculate the F Value, on whose basis the null hypothesis is confirmed or rejected. If variance is higher between samples than within the null hypothesis is more likely to be rejected. The results of a numerical example are interpreted more abstractly and then tested with regards to a confidence interval and the corresponding F table.

Der Klimawandel – beziehungsweise die Emission von Treibhausgasen – hat gegenläufige Effekte auf die gesellschaftliche Wohlfahrt. Einerseits emittieren wir Treibhausgase, um Wohlfahrt stiftende Aktivitäten auszuüben (Mobilität, Ernährung, Wärmeerzeugung etc.). Andererseits verändert die zunehmende THG- Konzentration klimatische Systeme, wodurch die Wohlfahrt der in der Zukunft lebenden Menschen beeinträchtigt wird. Klimaökonom*innen gehen der Herausforderung nach, die beiden Effekte zu quantifizieren und zu bestimmen, wie viele Treibhausgase zu welchem Zeitpunkt in der Zukunft emittiert werden sollten, damit die gesellschaftliche Wohlfahrt über mehrere Generationen hinweg maximiert wird.
Was eine moderne Klimaökonomik berücksichtigen sollte
Momentan findet in der Klimapolitik eine Verzögerungstaktik unter dem Vorwand „sozialer“ Gestaltung der Klimapolitik statt. Noch unsozialer wäre es jedoch, eine noch uneffektivere Klimapolitik zu machen. Der Grund dafür liegt in einem Zusammenhang von Ungleichheit und Klimawandel, den der englische Wissenschaftler Ian Gough im Journal of Social Policy unter dem Begriff „Dreifache (Un-)gerechtigkeit“ erläutert.

Gemäß der „vorsorgeorientierten Postwachstumsposition“ ist es ungewiss, wie sich die Wirtschaftsleistung entwickeln wird, wenn die Wirtschaftsweise in den wohlhabenden Ländern im Einklang mit globalen ökologischen Zielen grundlegend verändert wird. Andererseits spielen aufgrund der heutigen Verfasstheit der früh industrialisierten, wohlhabenden Länder die Wirtschaftsleistung und die damit generierten Einkommen eine wichtige Rolle. Daraus lässt sich das Ziel ableiten, diese gesellschaftlichen Institutionen nach Möglichkeit vorsorglich so zu transformieren, dass sie ihre Funktionen unabhängig(er) von der Wirtschaftsleistung erbringen können. Dies würde der Politik auch größere Spielräume bei Konflikten zwischen ökonomischen und ökologischen Zielen ermöglichen.
Die vorsorgeorientierte Postwachstumsposition
The definition of a chi-square distribution is given. Chi-square is defined as the sum of random normally distributed variables (mean=0, variance=s.d.=1). The number of added squared variables is equal to the degrees of freedom. With more degrees of freedom the probability of larger chi-square values is increased.
Chi-square distribution introduction
First some properties about the Sum of squared residuals and the linear regression function are restated. In particular three properties that an ideal fitted regression line must fulfill are discussed. Then, the R squared is defined using the measures of the Sum of squared residuals, the total sum of squares and the sum of explained squares.
Econometrics // Lecture 3: OLS and Goodness-Of-Fit (R-Squared)
First some definitions regarding econometrics, regressions, types of data and independent and dependent variables are given. Then the basic function of a simple regression analysis is explained. Lastly, there is discussion of the meaning of the error term.

How much money can banks create - Banking 101 (Part 4 of 6)
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
With the onset of an economic crisis that has been universally acknowledged since the end of March, two main questions arise: To what extent is the corona pandemic the starting point (or even the cause) of this crisis? And secondly: can the aid programmes that have been adopted prevent a deep and prolonged recession?
Economic crisis only because of the Corona pandemic?
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
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
In the interview, Robert Skidelsky discusses the emergence of political influence of a certain school of economic thought and how the success of an economic theory depends on the power relations in the society. He introduces the historical example of Keynesian economics and its replacement by liberal economic theory and policy in the aftermath of the Great Depression, and transfers this historical case to the dominant paradigm of austerity policies in the Europe as response to rising public debts caused by the Financial Crisis. He contrasts austerity policies with a Keynesian approach. Furthermore, he relates the targets of policy to the underlying power structures, for example when not the reduction of unemployment but the protection of financial capital is politically addressed.
Economics and Political Power during the Crisis
Silvia Federici illustrates the potential of the concept of the commons as way of resistance and reorganization of the society in times of social injustice and ecological crisis. Amongst others, she outlines the role of women in the commons movement.
Federici explains why she regards the theory of the tragedy of the commons as unfounded and why she considers Marx's concept of primitive accumulation as still appropriate to describe current events of deprivation, such as land grabbing.
The Struggle for the Commons
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.
Social experiments to fight poverty
Christoph Freydorf geht der Frage nach, ob Marktwirtschaft ohne das Privateigentum an natürlichen Ressourcen funktionieren kann. Zunächst präsentiert er gängige Argumentationslinien in der Ökonomie, die sich für die Notwendigkeit von Privateigentum an Ressourcen aussprechen, insbesondere Leistungsgerechtigkeit und effizienter Nutzung. Anschließend präsentiert Freydorf Kritik an diesen Argumente und stellt eine ordnungspolitische Regulierung vor, die diese Kritik aufnimmt: die Ausgabe von und den Handel mit Ressourcenzertifikaten.

How is money really made by banks? - Banking 101 (Part 3 of 6)
Sebastian Thieme geht der Frage nach, ob die Wirtschaftswissenschaften misanthropische Elemente und Wirkungen hat. Thiemes Vortrag befasst sich mit menschenfeindlichen Abwertungen, die in einem ökonomischen Kontext stehen (z.B. die Wertung von Arbeitslosigkeit als unproduktiv) und deren sozialpolitischen Auswirkungen. Er diskutiert dabei die Rolle von Konzepten wie Effizienz, Nützlichkeit, Wettbewerb, Konkurrenz und Selektion.
Misanthropie und Ökonomik
Walter Ötsch stellt die Ergebnisse einer Netzwerkanalyse eines Datensatzes zu Deutschen ordoliberalen Ökonomen in der Nachkriegszeit vor. Um die Daten zu interpretieren, verwendet er die Netzwerktheorie von Bruno Latour und kontextualisiert die Verbindungen der Personen im Netzwerk mit historischen Daten. Die Interpretation der Daten legt nahe, dass schon vor dem Zweiten Weltkrieg, aber insbesondere danach, Ordoliberale enge Verbindungen mit politischen und unternehmerischen Akteuren sowie Akademikern der Neoklassischen und Österreichischen Tradition hatte. Diese Netzwerke hatten auch eine internationale Dimension. Laut Ötsch hielt diese Netzwerke der gemeinsame Gegenpol zur Keynesianischen Theorie zusammen sowie ihre binäre Interpretation des Markt-Staat Verhältnisses.
Marktradikalismus als politische Ökonomie - Das Beispiel der Ordoliberalen
In diesem Text aus der Reihe "Exploring Economics - Foundations" werden die Grundlagen der Internationalen Politischen Ökonomie als interdisziplinäre wissenschaftliche Strömung dargestellt.
Internationale Politische Ökonomie
In the history of the social sciences, few individuals have exerted as much influence as has Jeremy Bentham. His attempt to become “the Newton of morals” has left a marked impression upon the methodology and form of analysis that social sciences like economics and political science have chosen as modus operandi.
Bentham’s Two Sovereign Masters - Examining Bentham’s Influence on the Social Sciences
As the Covid-19 fueled economic downturn begins to intensify this winter, an extended study of the Italian cooperative sector’s historical resilience in times of crisis can serve as a learning experience for other countries seeking to create policies that foster more stable economies, with job security, care for marginalized communities and adequate counter-cyclical policies. Particularly, the Italian cooperative sector’s contributions to three aspects should be noted in closing. Firstly, the innovative phenomenon of cooperative enterprises has contributed to social inclusion of immigrant communities, the activation of youth, the unemployed and people with disabilities, a true compensation for both a market and state failure. Secondly, they have contributed to a reduction in income and wealth inequalities at a time when the issue of inequality is of global significance. Thirdly, the Italian cooperative movement has helped local communities revitalize in the face of demographic shifts and rendered them more resilient to the ravages of globalization. Each of these in their own right is a remarkable achievement.
How to strengthen the social economy
In this radio interview, Andrew Sayer first outlines some features of neoliberalism and policies that are associated with it. Then a difference between wealth creation via investment and wealth extraction by means of lending money to those deprived of it or by acquiring property such as real estate or financial assets on the secondary market as absentee owner is established. In this context reference is made to J.A. Hobson's concept of "improperty." Finally, there are some words on the power dynamics associated with capitalism and its relation to climate change.
Why We Can’t Afford the Rich
In this lecture Ben Fine aims at stimulating interest for and explaining the relevance of Marxist Political Economy. Ben Fine dedicates the first half of his comprehensible lecture to the question on how mainstream economics became the way it is by explaining its key concepts and how those evolved during the past 150 years. While critically reflecting those concept he also emphasizes that mainstream economics does not consider historical processes. This is the point of departure on his presentation of the core terms and crucial categories of Marxist Political Economy: e.g. the production process and class relations (Part 1). Part 2 examines the consequences of the capitalist mode of production and its propensity to crises. Ben Fine illustrates this Marxist analysis with the example of the current crisis and explains current conditions for the accumulation of capital.
