The chi-square distribution is used to test a hypothesis. Therefore, expected values are related to observed values using a chi-square distribution. Then using p-value tables the hypothesis is tested at a 5% significance level.
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.
Environmental catastrophe looms large over politics: from the young person’s climate march to Alexandria Ocasio-Cortez’s Green New Deal, increasing amounts of political space are devoted to the issue. Central to this debate is the question of whether economic growth inevitably leads to environmental issues such as depleted finite resources and increased waste, disruption of natural cycles and ecosystems, and of course climate change. Growth is the focal point of the de-growth and zero-growth movements who charge that despite efficiency gains, increased GDP always results in increased use of energy and emissions. On the other side of the debate, advocates of continued growth (largely mainstream economists) believe that technological progress and policies can ‘decouple’ growth from emissions.
Based on a critique on econometric and DSGE models (in particular in the context of the financial crisis), Doyne Farmer presents his current research programme that aims at building an agent-based model of the financial and economic crisis. It models heterogeneous agents and from there simulates the economy, firstly for the housing market. The interview gives a short insight in the research programme.
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.
Sheila Dow discusses the concept of radical uncertainty and the failure of neoclassical economics to integrate it into its analysis. As to the implications for financial regulation that arise from the presence of radical uncertainty she argues for institutional overhaul, where the banks see themselves as a licensed partner of the central bank and where rules, values, and conventions would be subject to a cultural shift. Also, Sheila Dow advocates for a renewed focus on retail banking.
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.
In this Ted Talk, Mariana Mazzucato argues against the juxtaposition of the state and entrepreneurial activities. By presenting examples of her research on the relation between innovation and (inclusive) growth, she shows how many innovations were led by states' initiatives. Mazzucato confronts the liberal narrative of the a state that merely provides the frame for the market.
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.
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 short talk „On Economics“ Ha-Joon Chang, author of the book „Economics: The User's Guide“, gives a critical wrap-up on the economic discipline – on what is perceived as economics, what are dominant paradigms, the role of numbers and economics in public life. He further elaborates on the importance of heterodox schools of thought.
In the keynote speech, Sigrid Stagl argues why it is necessary to include socio-ecological aspects in macoreconomic models. The talk focuses on the ecological necessities, mentioning limits to growth, resource extraction and planetary boundaries. At the end, Stagl shortly presents several current macroeconomic initiatives and models that move towards a a socio-ecological macroeconomics.
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.
Stiglitz answers the question why globalization and world trade has not delivered on its promise of increased well being as much as classical economists thought, by pointing to the power asymmetries: firstly, between industrialized nations and developing nations and secondly, between special corporate interest and social interests. In his analysis, developed countries and MNCs were able to extract the benefits, while shifting the costs (i.e. pollution) to states and communities with lesser power. Amongst many other historical examples the pharmaceutical and the mining industry are discussed to some length.
The premise of this workshop is that we, as knowledge producers - especially within westernized universities (Grosfoguel, 2013), are significantly implicated in neoliberal imaginaries that are often in service of hierarchical, binary, competitive and linear narratives of growth as civilizational progress.
Does Karl Polanyi's work “The Great Transformation” serve to analyse the current multiple crisis and social movements? Nancy Fraser revises Polanyi's concept of a double movement to capture social forces in the aftermath of the economic crisis of the 1930s – on the one side marketization and on the other hand social protection. Fraser proposes to talk about a triple movement and to account for emancipatory struggles. In the lecture, she discusses interactions as well as conflicts between those three forces, in particular conflicting aims of social protection. The lecture presents the content of her paper “A TRIPLE MOVEMENT? Parsing the Politics of Crisis after Polanyi“ in the New Left Review (2013).
Galbraith first explores the social darwinism of Herbert Spencer and others that served as apology for the highly unequal distribution of wealth in the US at the end of the 19th century and naturalized differences in wealth by appealing to the concept of natural selection of the fittest. Then some instances of the unscrupulous business practices (i.e. robberies) of the American railroad tycoons and other business magnates are recounted. Lastly, Galbraith lines out some of the arguments of Thorstein Veblen, who delegitimized and ridiculed the business and leisure activities of the rich by putting them in the same category as predatory and ritualized practices of primitive or ancient societies.
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.
Critique of neoclassical economics is presented and contrasted with the more realistic assumptions made by an complex adaptive systems and evolutionary approach.
Silvia Federici outlines the content of her book „Caliban and the Witch - Women, the Body and Primitive Accumulation“. Departing from a critique of the Marxist blindspot on reproductive labour, Federici aims at researching the historical process by which the exploitation of women and the construction of the unproductive housewife has been established. Federici points to the transition from the feudal to the capitalist mode of production and explains how the gender specific prosecution (witch hunt) was linked to necessity of control over bodies and the sexuality in the great transformation. Federici also presents arguments why this research is highly relevant for the analysis of women's situation in current capitalism.
In this lecture Mirowski claims that a good critique of and alternative to neoclassical economics should focus on microeconomics. In addition, he claims that mainstream economics is not about a specific "human nature", instead the understanding of markets (partially based on Hayek) is of special importance. As an alternative Mirowski proposes institutionalist economics that builds upon how markets work nowadays (e.g. links to computer science).
Paul Mason presents the main arguments of his book PostCapitalism. First, he argues that capitalism runs out of its capability to adapt to crises and second states that information technology challenges the capitalist system. In a nutshell, he argues that a society which fully exploits information technologies can't include concepts such as intellectual property, free market or private ownership. This has far-reaching consequences for the organisation of wages and work. The talk stops at minute 37.30.
In this lecture, Konstantinos Katsikopoulos presents the concept of bounded rationality and contrasts two - as he calls it - cultures of research and analysis within Behavioral Economics: an "idealistic" and a "pragmatic" approach. Thereby, Katsikopoulos discusses amongst others their different assumptions on decision making (utility optimization vs. achievement of a satisfactory outcome), the psychological process as well as the epistemic aim and implications on policy recommendations (nudging vs. education).
The guides provide links to texts by Marx and Engels and present possible questions to discuss in study groups. The texts include Capial Volumes I – III, Economic & Philosophical Manuscripts or “Value, Price and Profit”.

This dossier gives an overview of the functions and the nature of money. The concept of Islamic finance is briefly explored, too.
What is innovation, what drives innovation and the process that differentiates firms? What is competition and what kind of dynamics lie behind the differences between firms and their innovative activities? Mariana Mazzucato elaborates on those questions from an evolutionary economics' and Schumpeterian perspective. The slides of her lecture are not visible, hence some visualizations can't be followed.
Feminist economist Nancy Folbre presents a historical analysis of the interrelated development of Patriarchy and Capitalism. She describes the role of women in the reproduction of labour, their “specialization” in care and their changing involvement in the labour market. Folbre argues that capitalism weakens patriarchy but at the same time relies on unpaid caring activities.
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.
