Untitled[edit]

Perhaps someone should make a page comparing and contrasting Thunen and Ricardian rent.

Model[edit]

The article says : "R = Y(p − c) − YFm, where R=land rent; Y=yield per unit of land; c=production expenses per unit of land; p=market price per unit of commodity; F=freight rate; m=distance to market". To be correct, 'c' has to be production expenses per unit of commodity. The current formula is wrong.--Franchute 08:04, 23 May 2007 (UTC)[reply]
