A SIMPLE EXPLANATION OF THE SHAPE OF MULTIPLE CAR OWNERSHIP

The paper develops a theoretical explanation of the different car ownership levels as a function of income. The basis is purely mathematical, and deals with aggregate figures. However, only a few coefficients are needed, i.e. A saturation level of ownership of one or more cars (accounting for those who cannot own a car whatever their income), and transition probabilities between each level of ownership. Calibrations are given from GLTS data and French data. They give quite comparable results. The theory is still incomplete, and may be expanded on more accuracy, and be applied to other phenomena.
