Economics

Economics (/iːkəˈnɒmɪks/, /ɛkəˈnɒmɪks/, /ɛkəˈnɑːmɪks/, /ikəˈnɑːmɪks/) is a social science concerned with the factors that determine the production, distribution, and consumption of goods and services. The term economics comes from the Ancient Greek from (oikos, pronounced eekos, "house") and (nomos, "custom" or "law"), hence "rules of the house (hold for good management)". 'Political economy' was the earlier name for the subject, but economists in the late 19th century suggested "economics" as a shorter term for "economic science" to establish itself as a separate discipline outside of political science and other social sciences.
