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.
History of discipline 
The new economic history originated in 1958 with the work of Alfred Conrad and John R. Meyer with the publication of "The Economics of Slavery in the Antebellum South," in the Journal of Political Economy. The new economic history revolution actually began in the mid-1960s and was resisted because many incumbent economic historians were either historians or economists who had very little connection to economic modeling or statistical techniques. Areas of key interest included transportation history, slavery, and agriculture. Cliometrics become better known when Douglass North and William Parker became the editors of the Journal of Economic History in 1960. The Cliometrics Meetings began to be held around this time at Purdue University and are still held annually in different locations. Today, cliometric approaches are standard in several journals, including the Journal of Economic History, Explorations in Economic History, the European Review of Economic History, and Cliometrica.
According to economist Claudia Goldin, the success of the cliometric revolution had as an unintended consequence the disappearance of economic historians from history departments. As economic historians started using the same tools as economists, they started to seem more like other economists. In Goldin's words, "the new economic historians extinguished the other side". The other side nearly disappeared altogether, with only a few remaining in history departments and business schools. However, some new economic historians did, in fact, begin research around this time, among them were Kemmerer and Larry Neal (a student of Albert Fishlow, a leader of the cliometric revolution) from Illinois, Paul Uselding from Johns Hopkins, Jeremy Atack from Indiana, and Thomas Ulen from Stanford. In spite of this, the separation of economic history and economics continued until the 1970s.
A group to encourage and further the study of cliometrics, The Cliometric Society, was founded in 1983.
Nobel Memorial Prize in Economics 
In October 1993, the Royal Bank of Sweden awarded the Nobel Prize in Economics to Robert William Fogel and Douglass Cecil North "for having renewed research in economic history." The Academy noted that "they were pioneers in the branch of economic history that has been called the 'new economic history,' or cliometrics." Fogel and North received the prize for turning the theoretical and statistical tools of modern economics on the historical past: on subjects ranging from slavery and railroads to ocean shipping and property rights.
Fogel is often described as the father of modern econometric history. He's especially noted for using careful empirical work to overturn conventional wisdom. North, a professor at Washington University in St. Louis, was honored as a pioneer in the "new" institutional history. In the Nobel announcement, specific mention was made of a 1968 paper on ocean shipping, in which North showed that organizational changes played a greater role in increasing productivity than did technical change.
Cliodynamics is a new multidisciplinary area of research focused at mathematical modeling of historical dynamics. It investigates dynamic processes in history, and is led by Peter Turchin and Andrey Korotayev. The term was originally coined by Peter Turchin in 2003.
