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.
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.
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.
Designed to give second-year undergraduates an intuitive understanding of basic mathematical techniques, and when and why they are applicable. Building on the traditional framework of calculus, the notion of a concave function is used to link the new algebraic methods with the more familiar graphical approachoand to introduce the modern use of duality in economic analysis.
Mainstream economic theory has been increasingly questioned following the recent global financial crisis. Marc Lavoie shows how post-Keynesian theory can function as a coherent substitute by focusing on realistic assumptions and integrating the financial and real sides of the economy.
Why is it that some countries become rich while others remain poor? Do markets require regulation to function efficiently? If markets offer an efficient way of exchanging goods, why do individuals even create firms?
In this video, Clara Mattei investigates the function of austerity in relation the stabilization of capitalism as a form of social order build around private property, wage labor and class relations. In order to develop this argument, she situates austerity in the history of World War 1 and its revolutionary aftermath. Zooming in on the politicization of the economy and the associated threat to class society that emerged in the period, she highlights how austerity was a „tool of reaction“ that was successful in curtailing demands for economic democracy and a society free from class oppression.
Austrian economics focuses on the economic coordination of individuals in a market economy. Austrian economics emphasises individualism, subjectivism, laissez-faire politics, uncertainty and the role of the entrepreneur, amongst others.
In the history of the social sciences, few individuals have exerted as much influence as has Jeremy Bentham. His attempt to become “the Newton of morals” has left a marked impression upon the methodology and form of analysis that social sciences like economics and political science have chosen as modus operandi.
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.
The concept of financialisation has undergone a similar career as ‘globalisation’, ‘neoliberalism’ or even ‘capitalism’, in the course of which it changed from the explanandum to the explanans; the process of financialisation is taken for granted, while the concrete historical and empirical causal conditions of its realisation and perpetuation are being moved into the background.
This article outlines the fundamental challenges of democratically planned economies and categorises proposed models into six groups, each of which approaches planning and coordination at different levels of authority and between myriad economic units in a particular way, taking into account efficiency as well as democratic principles and environmental and social sustainability. Through a classification system based on decision-making authority and mediation mechanisms, the article provides a framework for understanding and comparing these models. By examining their different approaches, it offers insights into the complexities and potential paths of democratically planned economies in the 21st century.

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.
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.
This text provides an easy to understand introduction to complexity economics for non-specialist audiences such as bachelor's students.
In this essay the author elaborates on the EU's perspective on the fast growing sector of the platform economy.
Approaching the law of nature that determines all forms of economy. The bulk of economic theory addresses the economic process by setting out on a catalogue of aspects, seeking the laws in the aspects and hoping to get together a reliable view of the whole.
With the onset of an economic crisis that has been universally acknowledged since the end of March, two main questions arise: To what extent is the corona pandemic the starting point (or even the cause) of this crisis? And secondly: can the aid programmes that have been adopted prevent a deep and prolonged recession?
The general idea of a Job Guarantee (JG) is that the government offers employment to everybody ready, willing and able to work for a living wage in the last instance as an Employer of Last Resort. The concept tackles societal needs that are not satisfied by market forces and the systemic characteristic of unemployment in capitalist societies. Being a central part of the Modern Monetary Theory (MMT), attention for the JG concept rose in recent years.
As the Covid-19 fueled economic downturn begins to intensify this winter, an extended study of the Italian cooperative sector’s historical resilience in times of crisis can serve as a learning experience for other countries seeking to create policies that foster more stable economies, with job security, care for marginalized communities and adequate counter-cyclical policies. Particularly, the Italian cooperative sector’s contributions to three aspects should be noted in closing. Firstly, the innovative phenomenon of cooperative enterprises has contributed to social inclusion of immigrant communities, the activation of youth, the unemployed and people with disabilities, a true compensation for both a market and state failure. Secondly, they have contributed to a reduction in income and wealth inequalities at a time when the issue of inequality is of global significance. Thirdly, the Italian cooperative movement has helped local communities revitalize in the face of demographic shifts and rendered them more resilient to the ravages of globalization. Each of these in their own right is a remarkable achievement.
The last 15 years have seen extensive research into ecosystem service valuation (ESV), spurred by the Millenium Ecosystem Assessment in 2005 (Baveye, Baveye & Gowdy, 2016). Ecosystem services are defined as “the benefits people obtain from ecosystems” (Millenium Ecosystem Assessment, p.V). For example, ecosystems provide the service of sequestering carbon which helps regulate the climate. Valuation means giving ecosystems or their services a monetary price, for example researchers have estimated that the carbon sequestration services of the Mediterranean Sea is between 100 and 1500 million euros per year. The idea of ESV was a response to the overuse of natural resources and degradation of ecosystems, allegedly due to their undervaluation and exclusion from the monetary economy. ESV can be used (1) for policy decision-making, for example allocating funding to a reforestation project (2) for setting payments to people who increase ecosystem services, for example a farmer increasing the organic carbon content of their soil, and (3) for determining fees for people who degrade ecosystem services, for example a company that causes deforestation.
Behavioural economics deals with observing behaviour and economic decision making behaviour.
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.
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.
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 18th century Europe figures such as Adam Smith, David Ricardo, Friedrich List and Jean Baptiste Colbert developed theories regarding international trade, which either embraced free trade seeing it as a positive sum game or recommended more cautious and strategic approaches to trade seeing it as a potential danger and a rivalry and often as a zero-sum game. What about today?
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.
Due to the IMF’s focus on gender budgeting, this essay will mainly examine its gender budgeting recommendations as an example of its general inclination towards gender issues and its conception of gender equality. What does the IMF’s focus on gender equality really mean from a critical feminist perspective? What are its main objectives? What does it seek to change and to maintain? What concept or idea of women does it follow and what are the underlying theoretical foundations?
This article explores if power dynamics in the household can be changed, and if so, how. In this context the focus is laid on government childcare policy and its various channels of possible influence.
