What is "cliometrics"

n. The use of econometrics to study economic history

Cliometrics, sometimes called new economic history, or econometric history, is the systematic application of economic theory, econometric techniques, and other formal or mathematical methods to the study of history (especially, social and economic history). It is a quantitative (as opposed to qualitative or ethnographic) approach to economic history. The term cliometrics comes from Clio, who was the muse of history, and was originally coined by the mathematical economist Stanley Reiter in 1960.
