Economist entities are the individual scholars this atlas documents, from foundational classical and marginalist figures through contemporary Nobel laureates and policy economists, grouped by primary field of contribution into the Journal of Economic Literature (JEL) top-level classification, the discipline's own standard scheme, run through economist's own thirteen currently populated bands: History of Economic Thought, Methodology, and Heterodox Approaches, Mathematical and Quantitative Methods, Microeconomics, Macroeconomics and Monetary Economics, International Economics, Public Economics, Health, Education, and Welfare, Labor and Demographic Economics, Law and Economics, Industrial Organization, Economic History, Economic Development, Innovation, and Growth, and Agricultural, Natural Resource, Environmental, and Ecological Economics, with the remaining seven top-level bands opening as a future economist gains a live member in that field. An economist's page links out to the school they are associated with, distinct from the JEL field grouping here, which classifies by subject contribution rather than by theoretical tradition.
