I'd like to start a list that could serve to measure the site's coverage of subfields of economics. This question is a partial response to the concerns expressed in the question, "How can we broaden the site's coverage of the various subfields of economics?". As a goal, it would be nice if we could find a question (or ask a new one if one doesn't already exist) from each of the 20 JEL classification categories. I've reproduces the list from the Wikpedia article here.
There are 20 primary JEL categories:
- JEL: A – General Economics, Handbooks and Teaching
- JEL: B – History of Economic Thought, Methodology, and Heterodox Approaches
- JEL: C – Mathematical and Quantitative Methods
- JEL: D – Microeconomics
- JEL: E – Macroeconomics and Monetary Economics
- JEL: F – International Economics
- JEL: G – Financial Economics
- JEL: H – Public Economics
- JEL: I – Health, Education, and Welfare
- JEL: J – Labor and Demographic Economics
- JEL: K – Law and Economics
- JEL: L – Industrial Organization
- JEL: M – Business Administration and Business Economics; Marketing; Accounting
- JEL: N – Economic History
- JEL: O – Economic Development, Technological Change, and Growth
- JEL: P – Economic Systems
- JEL: Q – Agricultural and Natural Resource Economics; Environmental and Ecological Economics
- JEL: R – Urban, Rural, and Regional Economics
- JEL: Y – Miscellaneous Categories
- JEL: Z – Other Special Topics.
Could we start by making each answer contain one or more example question from a single JEL category---one answer per JEL category?
From Wikipedia, Articles in economics journals are usually classified according to the JEL classification codes, a system originated by the Journal of Economic Literature.
