JEL classification codes
Articles in economics journals are usually classified according to JEL classification codes, which derive from the "Journal of Economic Literature". The "JEL" is published quarterly by the American Economic Association (AEA) and contains survey articles and information on recently published books and dissertations. The AEA maintains EconLit, a searchable data base of citations for articles, books, reviews, dissertations, and working papers classified by JEL codes for the years from 1969. A recent addition to EconLit is indexing of economics-journal articles from 1886 to 1968 parallel to the print series "Index of Economic Articles". Structure. There are  26 primary JEL categories: Each JEL primary category has secondary and tertiary subcategories, for example, under JEL: D – Microeconomics: JEL code (sub)categories, including periodic updates, are referenced at Journal of Economic Literature (JEL) Classification System. Links to definitions of (sub)categories are at JEL Classification Codes Guide with corresponding examples of article titles linked to publication information, such as abstracts. Purpose. Articles in economics journals also list JEL codes (for example ), facilitating their use across search engines. Comprehensive uses of JEL (sub)classifications include: JEL categories. A.
