VON THUNEN MODEL: A model of land use develop by Johann von Thunen that illustrates the trade off between land values and the distance from a central point of attraction. While originally applied to agricultural land use, the von Thunen model is commonly used to explain urban land use patterns. Two primary conclusions from the model are (1) that land values decrease as distance from the central point of attraction increases and (2) that different land use activities are contained in concentric rings equal distance from the central point of attraction based on the weight (or transportation cost) of the activity.

Economic theories are abstractions of the real world.
Three ways to abstract:- Words. The earliest human method of abstraction was to represent objects with words. Words also represent ideas. But words can have different meanings.
- Graphs. Pictures, especially graphical pictures. Many economic theories are abstractly represented with graphs. A picture or graph can be less confusing that words.
- Equations. Graphs are two-dimensional pictures of mathematical equations. Economic theories are often abstractly represented by equations. Equations can represent relationships between three or more things, like that for X, Y and Z:
Y = 3 + 2X - 4Z
