Definition – The cobweb theorem is an economic model used to explain how small economic shocks can become amplified by the behaviour of producers. Cobweb models explain irregular fluctuations in prices and quantities that may appear in some markets. The key issue in these models is time. The importance of the Cobweb Theorem is as one of earliest and easiest examples of dynamic analysis, which raises in sharp and relatively.

In response to the housing boom in Ireland, supply increased. This supply will be more than that required to satisfy demand at the price which prevailed at period 2, and so price must fall to induce buyers to take up the extra supply. This is true in this particular case because, the demand curve is the exact reverse of the supply curve so that at their overlap each has the same elasticity.

Cobweb theory

This is contrary to the principles of REH, where the measure of policies is an economic model, [6] not reality, and credibility, not truth. In the second period, there is a moderately reduced supply, Q 2with the corresponding higher price, P 2. The truth-value of a prediction is one measure in differentiating between non-deceiving and deceiving models. The Inconsistency of Optimal Plans. Should an ally blackmail the Coalition on the eve of.

Since this low price in the third period is identical with that in the first, the production and price in the fourth, fifth, and subsequent periods will continue to rotate around the path Q 2P 2Q 3P 3 etc.

The German concepts which translate literally “adjustment to lower” and “screw to lower” are known from the works of Hans-Peter Martin and Harald Schumann, the authors of The Global Trap.


The cobweb model has been interpreted as an explanation of fluctuations in various livestock markets, like those documented by Arthur Hanau in German hog markets; see Pork cycle. The equilibrium price is at the intersection of the supply and demand curves. Explore the year a word first appeared.

Of the three case considered thus so far, only this one behaves in the manner assumed by equilibrium theory ; and even it converges rapidly. Also, a low price will discourage farmers from growing that crop in the next year.

Rules Rather than Discretion: If they then expect low prices to continue, they will decrease their production of strawberries for the next year, resulting in high prices theofem. The importance of intellectual climate emphasized in Friedmans’ work [7] means that the credibility of a prediction can be increased by manipulating public opinion, despite its lack of truth.
