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.
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 Philosophy of Economics Foundational Text provides a systematic and well-structured overview over the field of philosophy of economics.
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.
The book is offered, in the first instance, to students who are beginners in economics, but some parts of it may be of wider interest. The three topics, Economic Doctrines, Analysis and Modern Problems, might be the subject of concurrent courses or they may be studied consecutively.
Here we look at the effect of the 2008 Climate Change Act passed in Parliament in the United Kingdom as an effort to curb emissions in all sectors. The Act aside from setting goals to become a low-carbon economy sets up an independent committee on Climate Change to ensure the implementation of policies to comply with the ultimate goal of 80% reduction in total emissions in 2050. I make use of the Synthetic Control Method (SCM) to create a comparative case study in which the creation of a synthetic UK serves as a counterfactual where the treatment never occurred (Cunningham, 2018).
Complexity economics focuses on interactions and interdependencies between individuals and structures in economic systems. Those are systems of organised complexity. High importance is given to the analysis of networks.
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.
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
This text provides an easy to understand introduction to complexity economics for non-specialist audiences such as bachelor's students.
A historical glimpse of how economists of the 19th century debated the usefulness of mathematics to economics
If there’s one method economists have neglected the most, it’s qualitative research. Whereas economists favour mathematical models and statistics, qualitative research seeks to understand the world through intensive investigation of particular circumstances, which usually entails interviewing people directly about their experiences. While this may sound simple to quantitative types the style, purpose, context, and interpretation of an interview can vary widely. Because of this variety, I have written a longer post than usual on this topic rather than doing it a disservice. Having said that, examples of qualitative research in economics are sadly scant enough that it doesn’t warrant multiple posts. In this post I will introduce qualitative research in general with nods to several applications including the study of firm behaviour, race, Austrian economics, and health economics. More than usual I will utilise block quotes, which I feel is in the spirit of the topic.
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 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.
Understanding international trade is central to economics and is currently a hot political issue. It’s an area where popular perceptions of mainstream economics are low, since they have historically missed some important downsides of trade agreements, especially the hollowing out of former manufacturing hubs in the Western world. et economists have for long time had a theory of trade with an impressive amount of scientific clout behind it: the gravity trade model.
This book presents a methodological framework for the analysis of intercultural issues frequently misinterpreted by existing theories. It uses a challenge-and-response theory of cultural development to examine the relationship between different natural disasters and threats and the developments of ancient civilizations.
Michael Kalecki famously remarked “I have found out what economics is; it is the science of confusing stocks with flows”. Stock-Flow Consistent (SFC) models were developed precisely to address this kind of confusion. The basic intuition of SFC models is that the economy is built up as a set of intersecting balance sheets, where transactions between entities are called flows and the value of the assets/liabilities they hold are called stocks. Wages are a flow; bank deposits are a stock, and confusing the two directly is a category error. In this edition of the pluralist showcase I will first describe the logic of SFC models – which is worth exploring in depth – before discussing empirical calibration and applications of the models. Warning that there is a little more maths in this post than usual (i.e. some), but you should be able to skip those parts and still easily get the picture.
This course provides future change makers in public and private sectors with a comprehensive overview on the structures and actors that shape markets.
What’s inflation? Why is it relevant? And is there an agreed theory about its roots and causes, or is it a contentious concept? That’s what this text is all about: We define what inflation actually means before we delve into the theoretical debate with an interdisciplinary and pluralist approach: What gives rise to it, what factors might influence it, and, consequently, what might be done about it?
The objective of this MOOC is to develop an understanding of the problems related to water management. Firstly, this course will define a resource and, more specifically, the resource of water. It will look at how water is used and the activities associated with it as well as any potential conflicts. The course will look at water management in detail through the analysis of the different types of rights and obligations associated with, for example, the development of a multi-sectorial regulation system or a watershed management approach.
Neoclassical economics focuses on the allocation of scarce resources. Economic analysis is mainly concerned with determining the efficient allocation of resources in order to increase welfare.
This syllabus provides an overview of the contents of the course "The Philosophy and Methodology of Economics" at the Duke University
This course offered by the International Monetary Fund (IMF) on edX provides an introduction in the major econometric tools used in standard Macroeconomics.
This book arose from our conviction that the NNS-DSGE approach to the analysis of aggregate market outcomes is fundamentally flawed. The practice of overcoming the SMD result by recurring to a fictitious RA leads to insurmountable methodological problems and lies at the root of DSGE models’ failure to satisfactorily explain real world features.
