Cobweb Theory Economics Help The cobweb model is generally based on a time lag between supply and demand decisions. agricultural markets are a context where the cobweb model might apply, since there is a lag between planting and harvesting (kaldor, 1934, p. 133–134 gives two agricultural examples: rubber and corn). suppose for example that as a result of unexpectedly bad. Now, if the slope of the supply function (β 1) is positive and that of the demand function (β 2) is negative, then to examine the convergence or divergence of the current price towards or away from the equilibrium level. this model is known as the cobweb model because, the path taken by the observed price and quantity resembles a cobweb.
Cobweb Theory Economics Help Cobweb theory. cobweb theory is the idea that price fluctuations can lead to fluctuations in supply which cause a cycle of rising and falling prices. in a simple cobweb model, we assume there is an agricultural market where supply can vary due to variable factors, such as the weather. Supply and demand following variations in crops” (besomi 2008, p. 633). in 1839, james wilson proposed an earlier version of cobweb like theory that explained “fluc tuations in grain supply and prices in terms of output in earlier years” (boot 1983, p. 567). endogenous price dynamics also appear in explanations of market instability. The cobweb model is an economic theory used to explain fluctuations in prices and quantities in markets with supply time lags. it suggests that producers base their supply decisions on prices prevailing in the market in the previous period (or periods), leading to a cyclical pattern of over and under production relative to demand. The cobweb model's prediction of a convergent or divergent pattern depends on the relative elasticities of supply and demand in the market. if the supply curve is more elastic than the demand curve, the model will predict a convergent pattern, where the market eventually reaches a stable equilibrium.

Static equilibrium of supply and demand’ and persistence of observed cycles in prices. use of an econometric model with a supply function using a lagged price combined with a demand function dependent on current price as an explanation for cyclical behavior arguably originates with moore (1925) (schultz 1928; morgan 1990, p.170).
