Concepts

Concept entities are the theories, models, laws and analytical tools this atlas documents, grouped by the Journal of Economic Literature (JEL) top-level classification, the discipline's own standard scheme for organizing the whole of economics into General Economics, History of Economic Thought, Mathematical Methods, Microeconomics, Macroeconomics and Monetary Economics, International Economics, Financial Economics, Public Economics, Labor Economics, Law and Economics, Industrial Organization, Business Economics, Economic History, Development and Growth, Economic Systems, Agricultural and Environmental Economics, Urban and Regional Economics and further miscellaneous and special-topic bands. This band is where a reader browses economics by its ideas rather than by the people who proposed them or the schools that champion them; several JEL bands carry no live concept yet and are deliberately left unminted as subcategories until a concept actually needs them, scaffolding ahead of the atlas's width push rather than a finished tree.
