Utility and demand:
The law of demand explains why the demand curve is negatively sloped, this law states that demand for a good declines as price rises and increases as prices decline. This law however applies to normal goods given that there are other types of goods that do not obey this law, example inferior and Veblen goods. For inferior goods as the income of consumers increase their demand declines, for example as the income increases for an individual who owns a bicycle he may decide to buy a car rather than buy another bicycle. Veblen goods also violate this law and they are those goods whose demand increases as their prices go up example luxurious products.
According to neoclassical economists one of the reasons why demand curve is negatively sloped is due to the substitution effect, this refers to a situation where good Z Women's Packers #52 Matthews Jersey is a close substitute of good T, as the price of good T increases then consumers will purchase good Z which is relatively cheap. For this
Income effect also explains the negatively sloped demand curve, the quantity of goods demanded by a consumer will depend on the level of income, a consumer with higher income levels will demand more goods, however the quantity of goods that a consumer will buy is limited by the price of that good, for example a consumer whose income is 1000 and the price of a good is 20 then the maximum quantity of that good the consumer can buy is 50. If the price of the good was increased from 20 to 50 then the maximum quantity of that good that the consumer will buy will be 20. Therefore as the price of a good increases then the consumer experiences a decline in his or her real income, real income being the quantity of goods the consumer can purchase.
Consumers demand for a good will also depend on the utility they gain from that good, when the utility gained from consuming a unit of a good is high then consumers will demand more of that good, according to the utility theory rational consumers aim at maximising utility by consuming more units, however the consumers will consume more and more units of that good until the marginal utility level is zero. For this reason therefore this explains why from our above example where the additional utility gained after consuming the second glass of water is greater than after consuming the fourth glass of water, marginal utility continues to decline until the value is zero and at this point the Women's Packers #52 Matthews Jersey consumer cannot consume more of that good.
