The Austrian school is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result primarily from the motivations and actions of individuals along with their self interest. Austrian-school theorists hold that economic theory should be exclusively derived from basic principles of human action.
Neoclassical economics is an approach to economics in which the production, consumption, and valuation (pricing) of goods and services are observed as driven by the supply and demand model. According to this line of thought, the value of a good or service is determined through a hypothetical maximization of utility by income-constrained individuals and of profits by firms facing production costs and employing available information and factors of production. This approach has often been justified by appealing to rational choice theory.
Rational choice theory refers to a set of guidelines that help understand economic and social behaviour. The theory originated in the eighteenth century and can be traced back to the political economist and philosopher Adam Smith. The theory postulates that an individual will perform a cost–benefit analysis to determine whether an option is right for them. Rational choice theory looks at three concepts: rational actors, self interest and the invisible hand.
The efficient-market hypothesis (EMH) is a hypothesis in financial economics that states that asset prices reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.
Feminist economics is the critical study of economics and economies, with a focus on gender-aware and inclusive economic inquiry and policy analysis. Feminist economic researchers include academics, activists, policy theorists, and practitioners. Much feminist economic research focuses on topics that have been neglected in the field, such as care work, intimate partner violence, or on economic theories which could be improved through better incorporation of gendered effects and interactions, such as between paid and unpaid sectors of economies. Other feminist scholars have engaged in new forms of data collection and measurement such as the Gender Empowerment Measure (GEM), and more gender-aware theories such as the capabilities approach. Feminist economics is oriented towards the goal of "enhancing the well-being of children, women, and men in local, national, and transnational communities."
Classical economics, classical political economy, or Smithian economics is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid-19th century. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange.
In the social sciences, methodological individualism is a method for explaining social phenomena strictly in terms of the decisions of individuals, each being moved by their own personal motivations. In contrast, explanations of social phenomena which assume that cause and effect acts upon whole classes or groups are deemed illusory, and thus rejected according to this approach. Or to put it another way, only group dynamics which can be explained in terms of individual subjective motivations are considered valid. With its bottom-up micro-level approach, methodological individualism is often contrasted with methodological holism, a top-down macro-level approach, and methodological pluralism.
Steve Keen is an Australian economist and author. He considers himself a post-Keynesian, criticising neoclassical economics as inconsistent, unscientific, and empirically unsupported.
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. A model may have various exogenous variables, and those variables may change to create various responses by economic variables. Methodological uses of models include investigation, theorizing, and fitting theories to the world.
Philosophy and economics studies topics such as public economics, behavioural economics, rationality, justice, history of economic thought, rational choice, the appraisal of economic outcomes, institutions and processes, the status of highly idealized economic models, the ontology of economic phenomena and the possibilities of acquiring knowledge of them.
Heterodox economics refers to attempts at treating the subject of economics that reject the standard tools and methodologies of mainstream economics, which constitute the scientific method as applied to the field of economics. These tools include:
Nicholas Georgescu-Roegen was a Romanian mathematician, statistician and economist. He is best known today for his 1971 magnum opus The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. A progenitor and a paradigm founder in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics.
In the history of economic thought, a school of economic thought is a group of economic thinkers who share or shared a mutual perspective on the way economies function. While economists do not always fit within particular schools, particularly in the modern era, classifying economists into schools of thought is common. Economic thought may be roughly divided into three phases: premodern, early modern and modern. Systematic economic theory has been developed primarily since the beginning of what is termed the modern era.
Microfoundations are an effort to understand macroeconomic phenomena in terms of economic agents' behaviors and their interactions. Research in microfoundations explores the link between macroeconomic and microeconomic principles in order to explore the aggregate relationships in macroeconomic models.
The Myth of the Rational Voter: Why Democracies Choose Bad Policies is a 2007 book by the economist Bryan Caplan, in which the author challenges the idea that voters are reasonable people whom society can trust to make laws. Rather, Caplan contends that voters are irrational in the political sphere and have systematically biased ideas concerning economics.
In economics, the freshwater school comprises US-based macroeconomists who, in the early 1970s, challenged the prevailing consensus in macroeconomics research. A key element of their approach was the argument that macroeconomics had to be dynamic and based on how individuals and institutions interact in markets and make decisions under uncertainty.
Thomas Palley is an American economist who was the chief economist for the United States-China Economic and Security Review Commission.
The Economics Anti-Textbook is both an introduction to, and critique of the typical approaches to economics teaching, written by Roderick Hill and Tony Myatt in 2010. The main thrust of the authors' argument is that basic economics courses, being centered on models of perfect competition, are biased towards the support of free market or laissez-faire ideologies, and neglect to mention conflicting evidence or give sufficient coverage of alternative descriptive models. This book has been updated and superseded by The Microeconomics Anti-Textbook and The Macroeconomics Anti-Textbook, by the same authors.
There have been many criticisms of econometrics' usefulness as a discipline and perceived widespread methodological shortcomings in econometric modelling practices.
Analytical Marxism is an academic school of Marxist theory which emerged in the late 1970s, largely prompted by G. A. Cohen's Karl Marx's Theory of History: A Defence (1978). In this book, Cohen drew on the Anglo–American tradition of analytic philosophy in an attempt to raise the standards of clarity and rigor within Marxist theory, which led to his distancing of Marxism from continental European philosophy. Analytical Marxism rejects much of the Hegelian and dialectical tradition associated with Marx's thought.
