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 the global mean is calculated from a matrix of three sets each containing three observations. Then the sum of squares is calculated. Lastly, the concept of degree of freedom is explained.
ANOVA 1: Calculating SST (total sum of squares)
The world is coping with a global disaster, as the new Coronavirus takes a toll on many lost lives and a severe impact on economic activity. To provide a long-run perspective, this column documents the international response to a variety of disasters since 1790. Based on a new comprehensive database on loans extended by governments and central banks, official (sovereign-to-sovereign) international lending is much larger than generally known. Official lending spikes in times of global turmoil, such as wars, financial crises or natural disasters. Indeed, in these periods, official capital flows have repeatedly surpassed total private capital flows in the past two centuries. Wars, in particular, were accompanied by large surges in the volume of official cross-border lending.
Coping with disasters: Lessons from two centuries of international response
Philosopher and political economist John Stuart Mill laid several foundations for liberal thinking, amongst others with the harm principle: everyone should be given the individual freedom - and not be hindered by e.g. state intervention - to act as s/he wants as long as no other person is harmed by this action. A short insight in his book On Liberty.
The Harm Principle: How to live your life the way you want to
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.
ANOVA 3: Hypothesis test with F-statistic
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.
ANOVA 2: Calculating SSW and SSB (total sum of squares within and between)
The 2007–08 credit crisis and the long recession that followed brutally exposed the economic and social costs of financialization. Understanding what lay behind these events, the rise of “fictitious capital” and its opaque logic, is crucial to grasping the social and political conditions under which we live. Yet, for most people, the operations of the financial system remain shrouded in mystery.
Fictitious Capital
The text presents a short perspective of International Political Economy, which "have often sought to complement discussions of governance with a healthy dose of critique", on resistance against e.g. economic inequality or economic and political power.

Dr Murieann Quigley (Senior Lecturer in Biomedical Ethics and Law, University of Bristol) discusses the ethics of nudging and whether it matters that third parties construct the context in which you make your decisions.

Croatia adopted the euro as its currency on 1 January 2023, becoming the 20th member state of the eurozone. In this teaching pack, students learn what it entails to join the eurozone and discuss what its effects might be. In this way, the case helps students connect theoretical insights about monetary unions with real world knowledge and economic developments in the news.

All leaders are constrained by geography. Their choices are limited by mountains, rivers, seas and concrete. People and ideas are important; but if you don't know geography, you'll never have the full picture.

It is fiercely debated when exactly the growth set off and what the drivers of Indian growth were. Scott Alexander summarises some of the recent literature on this question, demonstrating that not only the liberalisation policies of the 90s might be the driver of the take-off, but potentially public investments, political developments or cultural shifts.
Indian Economic Reform: Much More Than You Wanted To Know
In the late nineteenth and early twentieth centuries, Bombay was beset by crises such as famine and plague. Yet, rather than halting the flow of capital, these crises served to secure it. In colonial Bombay, capitalists and governors, Indian and British alike, used moments of crisis to justify interventions that delimited the city as a distinct object and progressively excluded laborers and migrants from it.

Regression Analysis: A Constructive Critique identifies a wide variety of problems with regression analysis as it is commonly used and then provides a number of ways in which practice could be improved.

Trade disputes are usually understood as conflicts between countries with competing national interests, but as Matthew C. Klein and Michael Pettis show in this book, they are often the unexpected result of domestic political choices to serve the interests of the rich at the expense of workers and ordinary retirees.

"Specialise!" is the advice often given by career advisers, school teachers and the like. David Epstein takes the opposite position: In an ever more specialised, highly complex world, it pays to have good old-fashioned broad common knowledge in as many areas as you take interest in, both in terms of intellectual curiosity and professional success. To have a decent grasp of various aspects of life means to be able to discern the links between them, thus developing a better understanding of how our world works and what drives events as they unfold.

Finance at the Threshold offers a unique perspective from an English economic and monetary historian. In it the author asks: Why did the banks stop lending to one another, and why now? Was it merely a matter of over-loose credit due to the relaxation of traditional prudence, or did global finance find itself at its limits?

Economic theory must distinguish between publicly owned and privately owned property if it is to account for the effect of institutions on the behavior of individuals. Careful study of the theories of Marxists and the real-world experience in the Soviet economy offer important lessons and insight for economic modeling and the ongoing development of theory. In this course, Marxist/Leninist theory and Soviet reality will be studied with an open mind, and with the goal of taking lessons from the case study. To what extent was the Soviet economy an accurate expression of Marxist theory? If Marxism were tried somewhere else would the results be the same?

Foreign exploitation of economic crises in the developing world has been a central claim of neoliberal critics. This important and recurring international theme is the subject of closer scrutiny in this new collection, where contributors offer competing interpretations of the interaction between international and domestic forces after crises.

John K. Galbraith tells the economic history of a couple of economies (mostly UK, US and to a lesser extent Germany) from the end of the first world war until the Bretton Woods conference. He also provides a biography of John M. Keynes and outlines some central ideas of Keynes such as the possibility of an underemployment equilibrium. Galbraith complements the historical remarks by the biographical experiences he made in economic management (and in engaging with Keynes) serving as deputy head of the Office for Price administration during the second world war.
