Economics is the social science (https://simple.wikipedia.org/wiki/Social_science) which studies economic activity: how people make choices (https://simple.wikipedia.org/wiki/Choice) to get what they want (https://simple.wikipedia.org/wiki/Want). It has been defined as "the study of scarcity and choice" and is basically about the choices people make. It also studies what affects the production, distribution and consumption (https://simple.wikipedia.org/wiki/Consumption_(economics)) of goods and services (https://simple.wikipedia.org/wiki/Service_(economics)) in an economy (https://simple.wikipedia.org/wiki/Economy).[1] (https://simple.wikipedia.org/wiki/Economics#cite_note-1)
Investment (https://simple.wikipedia.org/wiki/Investment) and income (https://simple.wikipedia.org/wiki/Income) relate to economics.[2] (https://simple.wikipedia.org/wiki/Economics#cite_note-2) The word comes from Ancient Greek (https://simple.wikipedia.org/wiki/Ancient_Greek_language), and relates to οἶκος oíkos "house" and νόμος nomos "custom" or "law".[3] (https://simple.wikipedia.org/wiki/Economics#cite_note-etymology-3) The models (https://simple.wikipedia.org/wiki/Scientific_model) used in economics today were mostly started in the 19th century. People took ideas from political economy (https://simple.wikipedia.org/wiki/Political_economy) and added to them because they wanted to use an empirical (https://simple.wikipedia.org/wiki/Empiricism) approach similar to the one used in the natural sciences (https://simple.wikipedia.org/wiki/Natural_sciences).[4] (https://simple.wikipedia.org/wiki/Economics#cite_note-Clark-4)
