Economics is the social science which studies economic activity: how people make choices to get what they 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 of goods and services in an economy.[1]

Investment and income relate to economics.[2] The word comes from Ancient Greek, and relates to οἶκος oíkos "house" and νόμος nomos "custom" or "law".[3] The models used in economics today were mostly started in the 19th century. People took ideas from political economy and added to them because they wanted to use an empirical approach similar to the one used in the natural sciences.[4]
