The demand curve is downward sloping illustrating the inverse relationship between quantity demanded and price. Therefore, a downward sloping demand curve embeds the law of demand. In a more specific manner: [3] = (,,,)
If income were to change, for example, the effect of the change would be represented by a change in the value of "a" and be reflected graphically as a shift of the demand curve. The constant b is the slope of the demand curve and shows how the price of the good affects the quantity demanded. [6]
According to the law of demand, the demand curve is always downward-sloping, meaning that as the price decreases, consumers will buy more of the good. Mathematically, a demand curve is represented by a demand function, giving the quantity demanded as a function of its price and as many other variables as desired to better explain quantity demanded.
The model assumes that when inflation rises the interest rate rises (monetary policy rule). It also assumes that when real GDP exceeds potential, there is upward pressure on the inflation rate and vice versa. The model features a downward-sloping demand curve (AD) and a horizontal inflation adjustment line (IA).
These inherited properties are not sufficient to guarantee that the excess demand curve is downward-sloping, as is usually assumed. The uniqueness of the equilibrium point is also not guaranteed. There may be more than one price vector at which the excess demand function is zero, which is the standard definition of equilibrium in this context. [14]
In microeconomics and consumer theory, a Giffen good is a product that people consume more of as the price rises and vice versa, violating the law of demand. For ordinary goods , as the price of the good rises, the substitution effect makes consumers purchase less of it, and more of substitute goods ; the income effect can either reinforce or ...
A Giffen good is a product that is in greater demand when the price increases, which are also special cases of inferior goods. [5] In the extreme case of income inferiority, the size of income effect overpowers the size of the substitution effect, leading to a positive overall change in demand responding to an increase in the price.
If the firm is a monopolist, the marginal revenue curve would have a negative slope as shown in the next graph, because it would be based on the downward-sloping market demand curve. The optimal output, shown in the graph as Q m {\displaystyle Q_{m}} , is the level of output at which marginal cost equals marginal revenue.
