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.
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 Role of Fiscal Policy in Climate Change Mitigation Via Environmental Management and Sustenance in Nigeria
An essay of the writing workshop on contemporary issues in the field of Nigerian economics: The adverse effect of climate change is overwhelming, not just in Nigeria but globally. Global warming is the result of hostile human activities that have impacted the environment negatively. This is the principal variable the government should tackle through practical innovations such as the acceptable implementation of Adaptation Policies and also through the adequate implementation of environmental tax. These will enhance pro-environmental behaviour which is fit for socio-political and economic activities for sustainability.
This course seeks to interpret capitalism using ideas from biological evolution. The lectures are foundational on neoclassical economics and economist, as well as their roles in the proliferation of capitalist ideology. However, it is less concerned with the ultimate judgment of capitalism than with the ways it can be shaped to fit more specific objectives.
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.
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?
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).
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.
How do people make decisions? There is a class of models in psychology which seek to answer this question but have received scant attention in economics despite some clear empirical successes. In a previous post I discussed one of these, Decision by Sampling, and this post will look at another: the so-called Fast and Frugal heuristics pioneered by the German psychologist Gerd Gigerenzer. Here the individual seeks out sufficient information to make a reasonable decision. They are ‘fast’ because they do not require massive computational effort to make a decision so can be done in seconds, and they are ‘frugal’ because they use as little information as possible to make the decision effectively.
What data is used in the economic models of the IPCC? How problematic is it, that tipping points are often ignored? A very interesting presentation by Steve Keen during the OECD Conference "Averting Systemic Collapse".
Politics as supermarket? Or how current policy design changes the relationship between the state and its citizens
What are the implications of the politics of "behavioural change"? Alexander Feldmann took a closer look for you on nudging and framing and if this is a legitimate instrument being used by the state to make us behave better in terms of our carbon footprint.
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.
Exploring Economics, an open-source e-learning platform, giving you the opportunity to discover & study a variety of economic theories, topics, and methods.
An essay of the writing workshop on Nigeria’s Readiness for and the Effect of the Fourth Industrial Revolution
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.
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.
In this essay, the principle of capital accumulation, as well as the idea of homo economicus as the basis of the growth model, are located and analyzed from a feminist perspective. The sufficiency approach is presented as an alternative to these two economic logics.
What influence do changes in tax policy or state decisions on expenditure have on economic growth? For decades, this question has been controversially debated.
The global financial crisis (GFC) led to increasing distrust in economic research and the economics profession, in the process of which the current state of economics and economic education in particular were heavily criticized. Against this background we conducted a study with undergraduate students of economics in order to capture their view of economic education.
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.
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.
Evolutionary economics focuses on economic change. Hence processes of change such as growth, innovation, structural and technological change, as well as economic development in general are analysed. Evolutionary economics often gives emphasis to populations and (sub-)systems.
“Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses1.” This is how Lionel Robbins came to define economics in the early 1930s and there is a good chance that many of you heard a variant of this definition in your first Economics 101 lecture.
On July 2020 ZOE-Institute published a unique platform for transformative policymaking: Sustainable Prosperity. Building on insights from new economic thinking the platform provides knowledge about ideas, arguments and procedures that support effective promotion of political change. It aims to strengthen change makers in public policy institutions, who are working on an ambitious green and just transition. As such, it provides convincing arguments and policy ideas to overcome the reliance of economic policy on GDP growth
The outbreak of COVID-19 has substantially accelerated the digitalization of the economy. Yet, this unprecedented growth of digital technology brought novel challenges to the labour market. Rise in income inequalities and precarious working conditions or polarization of jobs. In this essay, we try to assess what tools to use to counter these trends.
This course introduces students to political economy and the history of economic thought. We will cover the core ideas in various schools of economic thought, positioning them in the historical and institutional context in which they were developed. In particular, we will cover some economic ideas from the ancient world and the middle ages; the enlightenment; the emergence of and main ideas in classical political economy (Adam Smith, David Ricardo, Thomas Malthus, and others); Marx, Mill, and Keynes; European versus American economic thought through history; the rise of mathematical economics; economic theories around state-managed economies versus socialism; Austrian economics; behavioral economics; and the future of economics.
This workshop offers an introduction to Degrowth and Ecological Economics. It starts by surveying the socio-ecological crisis and its pseudo-solutions, and then moves to Ecological Macroeconomics as a relatively recent field of scholarship within Ecological Economics.
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.
In this course you'll learn about the tools used by scientists to understand complex systems. The topics you'll learn about include dynamics, chaos, fractals, information theory, self-organization, agent-based modeling, and networks.
The volume has been conceived with current and future economics students in mind: they will be the economists of the future. One of the main ideas underlining the book is that "being an economist" in the XXI century requires a radical change in the training of economists and such change requires a global effort.
IS-LM is perhaps the prime example of `cognitive dissonance' in economics, and is problematic to many economists. On the one hand, the IS-LM model is still taught by many academic economists or they use it to derive the AD-AS approach. On the other hand, the same economists realize the limitations of the basic IS-LM model and would not now use it for policy analysis, as they did in the past. The distinction between pedagogical and analytical efficacy is made by all the authors in this volume regarding the IS-LM model.
This book represents a new foundation for the study of microeconomics, viewed from a broad perspective that takes into account new developments at the intersections with psychology, political science, the natural sciences and philosophy.
