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.

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
In the second video of the series Investigating International Finance, an alternative view on capital controls is given contrasting with the paradigm of classical trade theory suggesting that the removal of trade and capital barriers is associated with higher market efficiency. After explaining the conceptual mechanisms underlying capital controls, examples are introduced where countries actually apply capital controls and how these controls have been associated with a lesser exposure to international financial crises spillovers.

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.

How do we get our dinner? And who cooked Adam Smith's dinner? Starting with Smith's answer on the origin of a dinner, Katrine Marçal problematizes and illustrates how unpaid labour was and is still being ignored by economic theory and how the homo economics represents characteristics perceived as male.
How Economics Forgot about Women
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.
Macroeconomics From the Bottom Up
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.

The total sum of squares and the total degrees of freedoms are disaggregated by calculating in sample variance and "between" sample variance and their respective degrees of freedoms. It is demonstrated numerically that both these measures add up to the total sum of squares and the total degrees of freedom.

Steve Keen discusses DSGE modeling and microfoundations by asking the question if it is ideologically possible to derive macroeconomics from microeconomics.
Discussing DSGE
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.
The Economics of Uncertainty
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.
Government - investor, risk-taker, innovator
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
First some terminology is explained. Then the interpretations of the coefficients and constants of the function are discussed. Afterwards the zero conditional mean assumption regarding the residual is problematized. Lastly, a graphical representation of a regression line is given and the least sum of squared errors is introduced and the equation for the coefficient of the linear function as well as for the intercept is given.

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.

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.
Introduction to Marxist Economics (Part 2)
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.
How The Economic Machine Works
In this keynote speech, Roger Backhouse gives a historical overview of theories on secular stagnation: how it evolved from a description of the economic situation, especially in the U.S. of the 1930s to an analytical tool and then lost importance until its current revival. Backhouse touches upon the contributions of J. A. Hobson, Alvin Hansen, Evsey Domar and Paul Samuelson.

In this radio interview, Philip Mirowski, author of the book "Never Let a Serious Crisis Go to Waste" presents several differences between neoclassical economics and neoliberalism. Apart from a historical outline, Mirowski primarily discusses different perceptions of markets and the role of the state. Mirowski further reflects on the role think tanks ("part of the "neoliberal thought collective") and the entrepreneurial self (the "neoliberal agent") in the spreading and fostering of the neoliberalism.
How Neoliberalism Survived the Financial Meltdown
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.

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).
