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.
Popular Assemblies and the Promise of Direct Democracy Many similarities exist between the new movements against austerity that have emerged since 2011 ranging from Taksim Square in Turkey to the Chilean student protests and from Greece to NYC One of them is their return to the principles of direct democracy …
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.
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.
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.
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.
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.
An essay of the writing workshop on contemporary issues in the field of Nigerian economics: Labour and all the dynamics, such as laws, mobility, gender participation, regulation etc., that are associated with it cements the need for this paper which seeks to objectively review, analyse, and if deemed necessary, give plausible recommendations.
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.
Trickle Down Economics - an old topic, but still present in our lives. The idea consists of deregulation of the economy and of lower tax for the top in order to increase the "size of the pie" so everybody would have a bigger piece, even with a smaller share.
This course provides future change makers in public and private sectors with a comprehensive overview on the structures and actors that shape markets.
In China's Gilded Age, Yuen Yuen Ang maintains that all corruption is harmful, but not all types of corruption hurt growth. Ang unbundles corruption into four varieties: petty theft, grand theft, speed money, and access money.
The most successful multialternative theories of decision making assume that people consider individual aspects of a choice and proceed via a process of elimination. Amos Tversky was one of the pioneers of this field, but modern decision theorists – most notably Neil Stewart – have moved things forward. At the current stage the theories are able to explain a number of strictly ‘irrational’ but reasonable quirks of human decision making, including various heuristics and biases. Not only this, but eye movements of participants strongly imply that the decision-making process depicted in the theories is an accurate one.
This paper starts with an evaluation of three common arguments against pluralism in economics: (1) the claim that economics is already pluralist, (2) the argument that if there was the need for greater plurality, it would emerge on its own, and (3) the assertion that pluralism means ‘anything goes’ and is thus unscientific. Pluralist responses to all three arguments are summarized. The third argument is identified to relate to a greater challenge for pluralism: an epistemological trade-off between diversity and consensus that suggests moving from a discussion about ‘pros’ and ‘cons’ towards a discussion about the adequate degree of plurality. We instantiate the trade-off by showing how it originates from two main challenges: the need to derive adequate quality criteria for a pluralist economics, and the necessity to propose strategies that ensure the communication across different research programs. The paper concludes with some strategies to meet these challenges.
Thirty-years of economic transformation has turned China into one of the major players in the global capitalist economy. However, its economic growth has generated rising problems in inequality, alienation, and sustainability with the agrarian crises of the 1990s giving rise to real social outcry to the extent that they became the object of central government policy reformulations.
With a focus on Chile, Pinochet’s Economic Accomplices: An Unequal Country byForce uses theoretical arguments and empirical studies to argue that focusing onthe behavior of economic actors of the dictatorship is crucial to achieve basic objectivesin terms of justice, memory, reparation, and non-repetition measures.
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.
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 analyzing the global competition between Chinese and Indian tea, Andrew B. Liu challenges past economic histories premised on the technical “divergence” between the West and the Rest, arguing instead that seemingly traditional technologies and practices were central to modern capital accumulation across Asia.
Richard Thaler gives a lecture in the 2018 Nora and Edward Ryerson Lecture at the University of Chicago. In the lecture he discusses his Nobel Prize winning research.
Caring activities are one central element of feminist economists' analysis – also since in particular unremunerated work is a blind spot in mainstream economics and most other economic paradigms. Those focus on the market sphere: activities are considered as productive and as real labour if they are remunerated and market-intermediated. Goods and services are considered as labour if they create a value which can be traded on the market. Feminist Economics remarks that this perspective creates certain dichotomies and consequent devaluations: unproductive – productive; private – public; unpaid – remunerated OR paid less – well paid; female – male; soft work – hard work; caring – rationality.
This chapter discusses the role of gender in economic relations, processes, and outcomes. Gender differences in economic outcomes such as labor force participation and wages have received growing attention from economists in the last several decades – a positive and much needed development in economic thinking.
A review of:  Intermediate Microeconomics, H.R. Varian  Mikrooekonomie, R.S. Pindyck, D.L. Rubinfeld  Grundzuege der mikrooekonomischen Theorie, J. Schumann, U. Meyer, W. Stroebele
Due to the economic crisis of 2008/2009, households faced drastic decreases in their incomes, the availability of jobs. Additionally, the structure of the labour market changed, while austerity measures and public spending cuts left households with less support and safeguards provided by the state. How have these developments affected the burden of unpaid labour and what influence did this have on gender relations?
Towards a post-work future: a necessary agenda to reconcile feminist & ecological concerns with work
In this essay the author outlines the basis for embracing a post-work agenda, rooted in an emancipatory potential from the domination of waged work, which could help answer both feminist and ecological concerns with work.
In this essay the author reviews empirical studies in economics that analyze factors behind the rise of nationalist and populist parties in Western countries. He stresses that economic factors (e.g., trade shocks and economic crisis) play a crucial role in the rise of populist parties; however, the discussion of mechanisms driving this trend remains unsatisfying
As opposed to the conventional over-simplified assumption of self-interested individuals, strong evidence points towards the presence of heterogeneous other-regarding preferences in agents. Incorporating social preferences – specifically, trust and reciprocity - and recognizing the non-constancy of these preferences across individuals can help models better represent the reality.
An essay of the writing workshop on contemporary issues in the field of Nigerian economics: In Nigeria, it appears that there is nothing in the constitution, which excludes the participation of women in politics. Yet, when it comes to actual practice, there is extensive discrimination. The under-representation of women in political participation gained root due to the patriarchal practice inherent in our society, much of which were obvious from pre-colonial era till date.
A historical glimpse of how economists of the 19th century debated the usefulness of mathematics to economics
In this podcast 'How Economic Theory and Policy Reinforce Racism' William Spriggs, the AFL-CIO’s chief economist, discusses the inadequacies of the pandemic economic rescue package and the influence of mainstream economic theory. He further explores how mainstream economic theory continues to fail everyone, especially Black communities, by disregarding history.
The course will teach students to analyze the goals, implementation, and outcomes of economic policy.
