“Intermediate between mathematics, statistics, and economics, we find a new discipline which, for lack of a better name, may be called econometrics. Econometrics has as its aim to subject abstract laws of theoretical political economy or "pure" economics to experimental and numerical verification, and thus to turn pure economics, as far as possible, into a science in the strict sense of the word.”

Accordingly, the quantitative study of economic phenomena here considered may be termed econometrics. <br class="br">Frisch (1927) as quoted in Divisia 1953, pp.24-25; Cited in: Bjerkholt, Olav. &quot; Ragnar Frisch and the foundation of the Econometric Society and Econometrica http://www.ssb.no/a/histstat/doc/doc_199509.pdf.&quot; ECONOMETRIC SOCIETY MONOGRAPHS 31 (1998): 26-57. <br class="br">Lead paragraph of a memorandum on the importance of establishing the journal &quot;Oekonometrika&quot; <br class="br">1920

Context: Our aim is to sketch the outlines of a new science which is to intermediate between the modern laboratory psychology and the problems of economics: the psychological experiment is systematically to be placed at the service of commerce and industry. So far we have only scattered beginnings of the new doctrine, only tentative efforts and disconnected attempts which have started, sometimes in economic, and sometimes in psychological, quarters. The time when an exact psychology of business life will be presented as a closed and perfected system lies very far distant. But the earlier the attention of wider circles is directed to its beginnings and to the importance and bearings of its tasks, the quicker and the more sound will be the development of this young science. What is most needed to-day at the beginning of the new movement are clear, concrete illustrations which demonstrate the possibilities of the new method. In the following pages, accordingly, it will be my aim to analyze the results of experiments which have actually been carried out, experiments belonging to many different spheres of economic life. But these detached experiments ought always at least to point to a connected whole; the single experiments will, therefore, always need a general discussion of the principles as a background. In the interest of such a wider perspective we may at first enter into some preparatory questions of theory. They may serve as an introduction which is to lead us to the actual economic life and the present achievements of experimental psychology
