Farm Size Distribution in EU(1987)Farm Size Distribution in EU(1987)Very skewed ownership:
• biggest 7 per cent of farmers owned ½ of the land• smallest 50 per cent of farmers owned only 7 per cent of the land.

But Now the price and quantity are gradually spiraling away from equilibrium.
This is an unstable cobweb.
Summary of Cobweb Effects
• With a demand SHIFT and supply fixed yearly, a sudden rise in demand will see a big increase in income.
• The lagged response next year can generate cyclical fluctuations in prices over the next few years.
• When Q goes up and P fall, income PxQ can also fluctuate.
• Not all cobwebs are stable

If elasticity equals 1 it means the percentage increase in quantity is
the same as the percentage fall in prices
So if the percentage price and income change is the
