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.
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.
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.

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.
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.
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.
Institutional economics focuses on the role of social institutions in terms of laws or contracts, but also those of social norms and patterns of human behaviour that are connected to the social organisation of production, distribution and consumption in the economy.
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.
An examination of women's changing economic roles. Includes an analysis of labour force participation, wage inequality, gender differences in education, intra-household distribution of resources, economics of reproduction, and how technological change affects women.
Capitalism cannot fulfil the promises of the French revolution: Liberty, Equality, Fraternity. Why? Richard Wollf elaborates on Marx's analysis of the distribution and organisation of surplus in society and his conclusion that there is something inherently wrong in capitalist class structure that still causes economic crisis in our modern times. Change requires changing the organisation of the production. This goes far beyond a discussion of 'more-state' vs. 'less-state'.
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.
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.
James Robinson gives in this talk a short introduction into the theory and ideas of his popular book "Why Nations Fail" which was published together with D. Acemoglu in 2012. With many real-life examples he gives a lively description on the fundamentals for economic success from an institutionalist view. According to Robinson, the nature of institutions is a crucial factor for economic success. Whether institutions are inclusive (such as in prosperous economies) or extractive (poor economies) stems from the nation's political process and the distribution of political power.
The first day of the workshop is intended to initiate students to the foundational concepts of ecological economics. Ecological economics is an ecological critique of economics, applying the energetics of life to the study of the economy. It also investigates the social distribution of environmental costs and benefits. It does so by deconstructing concepts that are taken for granted like “nature” or “the economy”, excavating their ideological origins.
Mainstream economics almost completely ignores the role power plays in determining economic outcomes, which means it can only provide partial explanations of the distribution of wealth and income, and of the problems associated with inequality and poverty.
In this short video Peter Reich illustrates seven aspects of the state of the US economy. He provides suggestions on how to to get started to move towards a more fair distribution of wealth.
From the two premises that (1) economies are complex systems and (2) the accumulation of knowledge about reality is desirable, I derive the conclusion that pluralism with regard to economic research programs is a more viable position to hold than monism. To substantiate this claim an epistemological framework of how scholars study their objects of inquiry and relate their models to reality is discussed. Furthermore, it is argued that given the current institutions of our scientific system, economics self-organizes towards a state of scientific unity. Since such a state is epistemologically inferior to a state of plurality, critical intervention is desirable.
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.
This text summarizes the content of the 2018 Nobel Prize winner W. Nordhaus. It is extended by some critical perspectives on this topic. The short dossier gives an overview of the most important texts we have read in the climate economics reading group.
More-is-better ideals such as these have long shaped our vision of rationality. Yet humans and other animals typically rely on simple heuristics to solve adaptive problems, focusing on one or a few important cues and ignoring the rest, and shortcutting computation rather than striving for as much as possible.
This course will survey contemporary heterodox approaches to economic research, both from a microeconomic and a macroeconomic perspective. Topics will be treated from a general, critical, and mathematical standpoint.
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.
By conducting a discourse analysis (SKAD) in the field of academic economics textbooks, this paper aims at reconstructing frames and identity options offered to undergraduate students relating to the questions ‘Why study economics?’ and ‘Who do I become by studying economics?’. The analysis showed three major frames and respective identity offerings, all of which are contextualized theoretically, with prominent reference to the Foucauldian reflection of the science of Political Economy. Surprisingly, none of them encourages the student to think critically, as could have been expected in a pedagogical context. Taken together, economics textbooks appear as a “total structure of actions brought to bear upon possible action” (Foucault), therefore, as a genuine example of Foucauldian power structures.
Behavioural economics deals with observing behaviour and economic decision making behaviour.
If there’s one method economists have neglected the most, it’s qualitative research. Whereas economists favour mathematical models and statistics, qualitative research seeks to understand the world through intensive investigation of particular circumstances, which usually entails interviewing people directly about their experiences. While this may sound simple to quantitative types the style, purpose, context, and interpretation of an interview can vary widely. Because of this variety, I have written a longer post than usual on this topic rather than doing it a disservice. Having said that, examples of qualitative research in economics are sadly scant enough that it doesn’t warrant multiple posts. In this post I will introduce qualitative research in general with nods to several applications including the study of firm behaviour, race, Austrian economics, and health economics. More than usual I will utilise block quotes, which I feel is in the spirit of the topic.
As seen with the United Nations significant promotion of the Sustainable Development Goals (SDGs) in the past few years, the issue of global development is of growing concern to many international organizations. As humanity continues to become more interconnected through globalization, the inequalities and injustices experienced by inhabitants of impacted countries becomes increasingly clear. While this issue can be observed in the papers of different types (e.g., different schools of thought) of economists throughout the world, the work of behavioral and complexity economists offer a unique, collaborative perspective on how to frame decisions for individuals in a way that can positively reverberate throughout society and throughout time.

Game theory is the standard quantitative tool for analyzing the interactions of multiple decision makers. Its applications extend to economics, biology, engineering and even cyber security.
This course attempts to explain the role and the importance of the financial system in the global economy. Rather than separating off the financial world from the rest of the economy, financial equilibrium is studied as an extension of economic equilibrium. The course also gives a picture of the kind of thinking and analysis done by hedge funds.
Politics as supermarket? Or how current policy design changes the relationship between the state and its citizens
What are the implications of the politics of "behavioural change"? Alexander Feldmann took a closer look for you on nudging and framing and if this is a legitimate instrument being used by the state to make us behave better in terms of our carbon footprint.
