Jan Pen

Jan Pen (15 February 1921 in Lemmer – 14 February 2010 in Haren) was a Dutch economist, professor and columnist. He is author of several books on economics.

Life and work
Pen studied at the University of Amsterdam, where in 1950 he received his PhD with a thesis concerning the theory of collective wage negotiations. He was Director General Economic Policy at the Ministry of Economic Affairs. In 1956 he was appointed professor of political economy and the theory of public finance at the Faculty of Law and the Faculty of Economics (FEW) of the University of Groningen. He published in 1959 Moderne Economie (Modern economy), for years the general introduction to macroeconomics in the Netherlands. It appeared in various translations, and in 1977 in an updated version entitled Marco-economie (Macroeconomics). Pen gave his farewell lecture in 1986, but remained active as emeritus professor at the Faculty of Economics FEW.

Pen is the creator of the so-called "Pen's parade", a graphical representation of income distribution. In this graph families or individuals are added along on the x-axis ranked from poor to rich, while the level of income is indicated on the y-axis. Another description for this graph is "Parade van dwergen en een enkele reus" (Parade of dwarfs and a single giant), because of the shape of the graph this image takes in many countries.

Pen became member of the Royal Netherlands Academy of Arts and Sciences in 1972.

In 1974 Jan Pen held the third Huizinga Lecture in Leiden. The title of the lecture was "The culture, the money and the people." For years he wrote as a columnist for Het Parool. He also wrote regularly in the Hollands Maandblad and Economisch Statistische Berichten (ESB).

In the 1975 novel Onder professoren about the academic scene in Groningen Willem Frederik Hermans referred to Jan Pen with the fictional character Tabe Pap.
