economist

noun

1. An expert in economics, especially one who studies economic data and extracts higher-level information or proposes theories.

   “Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.”

   “The formula, which AEI economists said had “no foundation in either economic theory or trade law,” instead wrongly incorporated the elasticity for retail prices. […] However, certainty is anything but a sure thing these days, and the bread-and-butter of the US economy might not go unscathed, said RSM economist Brusuelas.”

2. One concerned with political economy.
3. (obsolete)One who manages a household.
4. (obsolete)One who economizes, or manages domestic or other concerns with frugality; one who expends money, time, or labor, judiciously, and without waste.
