Local nonsatiation (LNS [2]) is often applied in consumer theory, a branch of microeconomics, as an important property often assumed in theorems and propositions.Consumer theory is a study of how individuals make decisions and spend their money based on their preferences and budget.
In most simple microeconomic stories of supply and demand a static equilibrium is observed in a market; however, economic equilibrium can be also dynamic. Equilibrium may also be economy-wide or general, as opposed to the partial equilibrium of a single market. Equilibrium can change if there is a change in demand or supply conditions.
Graphical representation of the consumption function, where a is autonomous consumption (affected by interest rates, consumer expectations, etc.), b is the marginal propensity to consume and Yd is disposable income. In economics, the consumption function describes a relationship between consumption and disposable income.
At competitive equilibrium, the value society places on a good is equivalent to the value of the resources given up to produce it (marginal benefit equals marginal cost). This ensures allocative efficiency : the additional value society places on another unit of the good is equal to what society must give up in resources to produce it.
A price-budget-line change that kept a consumer in equilibrium on the same indifference curve: in Fig. 1 would reduce quantity demanded of a good smoothly as price rose relatively for that good. in Fig. 2 would have either no effect on quantity demanded of either good (at one end of the budget constraint ) or would change quantity demanded from ...
Consumer assets and wealth: These refer to assets in the form of cash, bank deposits, securities, as well as physical assets such as stocks of durable goods or real estate such as houses, land, etc. These factors can affect consumption; if the mentioned assets are sufficiently liquid, they will remain in reserve and can be used in emergencies.
Market equilibrium occurs when the demand of a good at the equilibrium price is equal to the supply of the good. If prices are deemed "too high" by the consumers, supply will exceed demand, and sellers will have to reduce their prices until the market clears (i.e., equilibrium is reached).
The transition from the short-run to the long-run may be done by considering some short-run equilibrium that is also a long-run equilibrium as to supply and demand, then comparing that state against a new short-run and long-run equilibrium state from a change that disturbs equilibrium, say in the sales-tax rate, tracing out the short-run ...
