Johann Heinrich von Thünen

Overview

Johann Heinrich von Thünen (1783–1850), a north-German estate owner who bought the estate of Tellow in Mecklenburg in 1810 and ran it as a decades-long economic experiment — systematically recording labour inputs, yields, and costs — is the father of location theory. From that data he built The Isolated State (Der isolierte Staat, Volume 1 published 1826; Volume 2, on marginal analysis of wages and interest, worked out 1826–1848 and published 1850, with a further part posthumously in 1863).[1][2] It models an isolated city on a featureless plain and asks what land uses arise where: the answer — concentric rings of activity ordered by transport cost — makes land rent a function of distance to market, independent of fertility.[1] This is the spatial complement to Ricardo's fertility-differential account carried on the wiki's law of rent page: modern urban economics' location rent — the value the wiki's whole land corpus is about — descends from Thünen, and Blaug's history treats him as both location theory's founder and an independent pioneer of marginal productivity reasoning (Ch. 14).[1] The agglomeration and optimal city size literatures the wiki carries are his modern descendants.
