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 ...
This will tend to put downward pressure on the price to make it return to equilibrium. Likewise where the price is below the equilibrium point (also known as the "sweet spot" [3]) there is a shortage in supply leading to an increase in prices back to equilibrium. Not all equilibria are "stable" in the sense of equilibrium property P3.
Under general equilibrium theory prices are determined through market pricing by supply and demand. [6] Here asset prices jointly satisfy the requirement that the quantities of each asset supplied and the quantities demanded must be equal at that price - so called market clearing.
Over time, as well as to determine the factors driving equity premium in various countries / regions may still be active research agenda. [13] A 2023 paper by Edward McQuarrie argues the equity risk premium may not exist, at least not as is commonly understood, and is furthermore based on data from a too narrow a time period in the late 20th ...
The original equilibrium price is $3.00 and the equilibrium quantity is 100. The government then levies a tax of $0.50 on the sellers. This leads to a new supply curve which is shifted upward by $0.50 compared to the original supply curve. The new equilibrium price will sit between $3.00 and $3.50 and the equilibrium quantity will decrease.

The investor lives from time 0 to time T; their wealth at time T is denoted W T. He starts with a known initial wealth W 0 (which may include the present value of wage income). At time t he must choose what amount of his wealth to consume, c t , and what fraction of wealth to invest in a stock portfolio, π t (the remaining fraction 1 − π t ...
Example: there are three goods (a, b1, b2) and two voters, where Alice values a, b1 at 1 and b2 at 0, and George values a, b2 at 1 and b1 at 0. The budget of each agent is 3, and the cost of each good is 2. Producing only {a} is a Lindahl equilibrium, with prices for Alice: 2-0.009, 2-0.006, 0.001 and prices for George: 2-0.009, 0.001, 2-0.006.
