Applied economicsApplied economics is the study as regards the application of economic theory and econometrics in specific settings. As one of the two sets of fields of economics (the other set being the core), it is typically characterized by the application of the core, i.e. economic theory and econometrics to address practical issues in a range of fields including demographic economics, labour economics, business economics, industrial organization, agricultural economics, development economics, education economics, engineering economics, financial economics, health economics, monetary economics, public economics, and economic history.
Coase theoremIn law and economics, the Coase theorem (ˈkoʊs) describes the economic efficiency of an economic allocation or outcome in the presence of externalities. The theorem is significant because, if true, the conclusion is that it is possible for private individuals to make choices that can solve the problem of market externalities. The theorem states that if the provision of a good or service results in an externality and trade in that good or service is possible, then bargaining will lead to a Pareto efficient outcome regardless of the initial allocation of property.
Evolutionary economicsEvolutionary economics is a school of economic thought that is inspired by evolutionary biology. Although not defined by a strict set of principles and uniting various approaches, it treats economic development as a process rather than an equilibrium and emphasizes change (qualitative, organisational, and structural), innovation, complex interdependencies, self-evolving systems, and limited rationality as the drivers of economic evolution.
Economics of religionThe economics of religion concerns both the application of the techniques of economics to the study of religion and the relationship between economic and religious behaviours. Contemporary writers on the subject trace it back to Adam Smith (1776). Empirical work examines the causal influence of religion in microeconomics to explain individual behaviour and in the macroeconomic determinants of economic growth. Religious economics (or theological economics) is a related subject sometimes overlapping or conflated with the economics of religion.
Dynamic inconsistencyIn economics, dynamic inconsistency or time inconsistency is a situation in which a decision-maker's preferences change over time in such a way that a preference can become inconsistent at another point in time. This can be thought of as there being many different "selves" within decision makers, with each "self" representing the decision-maker at a different point in time; the inconsistency occurs when not all preferences are aligned.
The Quarterly Journal of EconomicsThe Quarterly Journal of Economics is a peer-reviewed academic journal published by the Oxford University Press for the Harvard University Department of Economics. Its current editors-in-chief are Robert J. Barro, Lawrence F. Katz, Nathan Nunn, Andrei Shleifer, and Stefanie Stantcheva. It is the oldest professional journal of economics in the English language, and covers all aspects of the field—from the journal's traditional emphasis on micro-theory to both empirical and theoretical macroeconomics.
Adverse selectionIn economics, insurance, and risk management, adverse selection is a market situation where buyers and sellers have different information. The result is the unequal distribution of benefits to both parties, with the party having the key information benefiting more. In an ideal world, buyers should pay a price which reflects their willingness to pay and the value to them of the product or service, and sellers should sell at a price which reflects the quality of their goods and services.
Philosophy and economicsPhilosophy 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. It is useful to divide philosophy of economics in this way into three subject matters which can be regarded respectively as branches of action theory, ethics (or normative social and political philosophy), and philosophy of science.
Herd behaviorHerd behavior is the behavior of individuals in a group acting collectively without centralized direction. Herd behavior occurs in animals in herds, packs, bird flocks, fish schools and so on, as well as in humans. Voting, demonstrations, riots, general strikes, sporting events, religious gatherings, everyday decision-making, judgement and opinion-forming, are all forms of human-based herd behavior. Raafat, Chater and Frith proposed an integrated approach to herding, describing two key issues, the mechanisms of transmission of thoughts or behavior between individuals and the patterns of connections between them.
Behavioral game theoryBehavioral game theory seeks to examine how people's strategic decision-making behavior is shaped by social preferences, social utility and other psychological factors. Behavioral game theory analyzes interactive strategic decisions and behavior using the methods of game theory, experimental economics, and experimental psychology. Experiments include testing deviations from typical simplifications of economic theory such as the independence axiom and neglect of altruism, fairness, and framing effects.
