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.
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.
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.
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.
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 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.
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.
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.
Economist and politician Costas Lapavitsas: presents differing theoretical definitions of financialization, namely from Marxist and Post-Keynesian thinkers and compares their approaches. By presenting pattern and features of the economic and financial crisis, he interprets the latter as a crisis of financialization. Lapavitsas emphasizes his arguments by presenting data from the U.S. and Germany on the transformation of business, banks and households.
In this lecture, Konstantinos Katsikopoulos presents the concept of bounded rationality and contrasts two - as he calls it - cultures of research and analysis within Behavioral Economics: an "idealistic" and a "pragmatic" approach. Thereby, Katsikopoulos discusses amongst others their different assumptions on decision making (utility optimization vs. achievement of a satisfactory outcome), the psychological process as well as the epistemic aim and implications on policy recommendations (nudging vs. education).
Ha Joon Chang exposes the main ideas of his book Bad Samaritans, namely that historically states have developed and industrialized by making policy interventions related to industry protection, tariffs and subsidies and not by opening their markets to free trade. Chang elaborates on the examples of Japan, the US, Singapore and Germany amongst others to show that an interventionist path to development has been the regularity and not an anomaly. In the end of the lecture, he argues that they idea of a level playing field should be replaced by a trade order that accounts for differences in power and economic capacities of different countries. The last 20 minutes are questions and answers.
Keen first compares neoclassical approaches to modelling with heterodox ones. Then he discusses in length the required assumptions and the inconsistencies of the aggregate demand and supply model, which is extrapolated from a micro perspective. At the end some dynamic models with feedback mechanisms are shown.
This multimedia dossier is part of the series „Understanding Finance“ by Finance Watch and presents a description and critical review of financial markets and their functions. It furthermore discusses recent developments, as high frequency trading.
The website contains a vast amount of information on the history of economic thought. It presents thinkers, their main works (and links to those works) and schools of thought which are sorted by political economy schools, neoclassical schools, alternative schools as well as thematic schools.
First historical instances of colonialism such as the crusades are revisited. Then a lengthy account of the colonial experience of the Spanish Kingdom in South America and of the British Empire in India is given. The Indian case is illustrated with large amounts of archival materials from a colonial administrator. There the workings of the colonial bureaucracy and law and its (positive) achievements as well as the ignorance and arrogance of the external rulers are demonstrated. After narrating the Indian independence to some depth some recent colonial wars (Algeria, Vietnam, Congo, Angola) are briefly examined. In the end, the impact of colonialism on current, i.e. 1970s, (economic) international relations is discussed. The general tenor is that colonialism is a dysfunctional system. Still, agency is mostly placed with the empire rather than with the ruled.
The dossier first discusses the impact of colonialism on introducing foreign plants and thus disrupting ecosystems. Subsequently the case of the knotweed, a plant introduced from Japan to the UK and now considered a threat to biodiversity is explored. The complex economy built around the plant consisting of regulations, pesticides, experts, and landowners is then explored.
Mark Blyth criticises the political inability to solve the persistent economic crisis in Europe against the background of a deflationary environment. Ideological blockades and impotent institutions are the mutually reinforcing causes of European stagnation. The deeper roots lie in the structural change of the economic system since the 1980s, when neoliberalism emerged as hegemonic ideology. This ideology prepared the ground for austerity and resulting deflationary pressures and a strategy of all seeking to export their way out of trouble. Worryingly this is breeding populist and nationalist resentments in Europe.
Irene van Staveren, professor of pluralist development economics, presents her pluralist teaching method for the introductory level. Based on her textbook “Economics After the Crisis: An Introduction to Economics from a Pluralist and Global Perspective” she suggests to focus on real-world problems and pari passu apply economic theories such as Social economics, Institutional economics, Post-Keynesian economics as well as Neoclassical economics without wasting time to single out the latter. Besides pointing out advantages of such a pluralist method Irene illustrates her approach based on interesting topics such as growth or feminist economics.
In the inspiring interview on Economics of Care, Nancy Foblre takes a closer look to the consequences of the marketization of caring activities on those activities and on the societal organization of care. Folbre elaborates on how to value care and how this shifts the perspectives on living standards. She points to the fact, that caring activities are undervalued both in the market sphere and within the family and thereby questions the division between those spheres. Lastly, Folbre answers the question how to reteach Economics when accounting for caring activities.
This video animates part of the talk “On Economics” by Ha-Joon Chang in which he states that economics is not a science for experts but for everyone. Chang further argues why it is important to take into account different perspectives on economics – he identifies at least nine school of thoughts which all have their strengths and weaknesses and presents examples on free trade and well-being. Chang further elaborates on the difficulties of changing the economic status quo.
With this calculator you can assess the ecological backpack of your lifestyle. The ecological backpack visualizes the weight of all natural raw materials that are needed for our private consumption behavior. This includes all products and their production, use, and disposal.
At the 2013 Climate, Mind, & Behavior Symposium, Rebecca Adamson of First Peoples Worldwide illustrates alternative economic systems modeled after indigenous worldviews and the power they have in pushing us towards a more sustainable existence.
Peter Boettke, Professor of Economics and Philosophy at George Mason University, talks about the history and the main methodological and epistemological tenets of the Austrian school. He argues that good economics is the mainline tradition of "squaring rational choice with the invisible hand theorem through institutional analysis".
In this talk, Virgil Henry Storr, a Research Associate Professor of Economics in the Department of Economics at George Mason University, talks about his research into to post-disaster recovery and the role that social entrepreneurship plays in rebuilding the communities and social networks that get disrupted, or entirely eliminated.
This lecture is all about the challenge to include heterodox approaches into macroeconomics. After giving an overview of recent approaches to that problem Professor Michael Roos presents the theoretical framework of Complexity Economics as a means to combine behavioral aspects with macroeconomics.
Robert Costanza briefly present various methods of environmental valuation, and talks about the changes in the global value of ecosystem services. He then introduces the major ecosystem services, and how different methods of valuation affect the preferred policies to address environmental issues.
In order to describe the global structure of the monetary and financial system and its effects on the global economy, most economics textbooks rely on unappropriated theories that provide nothing but outdated descriptions. In this talk, key speakers in economics, economic history and banking try to make this complex system a little more understandable by relying on real-world insights.
Donald Trump won in 2016 largely because enough voters in three states, all in the Rustbelt, which had voted for Barack Obama in both 2008 and 2012, switched their electoral votes from Democratic to Republican.
In this post, Rethinking Economics sets out what it means to decolonise economics education and how we can do that. The article first breaks decolonising down into a "mind-set" and a "process", then applies this process to economics education. It finishes with a reading list and some suggested actions to get you started decolonising economics today.
