What Are the Various Subfields of Economics

At the most basic level, the field of economics is divided into microeconomics, or the study of individual markets, and macroeconomics, or the study of the economy as a whole.  At a more granular level, however, economics has many subfields, depending on how finely you wish to divide the science. A useful classification system is provided by The Journal of Economic Literature. Subsets of Economics Here are some of the subfields that the JEL identifies: Mathematical and Quantitative MethodsEconometricsGame Theory and Bargaining TheoryExperimental EconomicsMicroeconomicsMacroeconomics and Monetary EconomicsThe Business CycleMoney and Interest RatesInternational Economics and International TradeFinance and Financial EconomicsPublic Economics, Taxation, and Government SpendingHealth, Education, and WelfareLabor and Demographic EconomicsLaw and EconomicsIndustrial OrganizationBusiness Administration and Business Economics; Marketing; AccountingEconomic HistoryEconomic Development, Technological Change, and GrowthEconomic SystemsAgricultural and Natural Resource EconomicsUrban, Rural, and Regional Economics In addition, there are a number of fields within economics that didnt significantly exist when the JEL classification was developed, such as behavioral economics, organizational economics, market design, social choice theory, and a number of others.
