Law of demand and demand curve. Non-price factors affecting the change in demand. Factors affecting demand.
ers are willing and the able to purchase. Law of demand: The lower the price of an item, the greater is the quantity demanded, other things (non-price determinants) being equal. Demand curve: A graph of the relationship between price and quantity demanded. The negative (downward) slope of the demand curve illustrates the law of demand. Change in demand: A change in the relationship between the price of an item and the quantity demanded caused by a change in something other than the price of an item (non-price determinants changes). Non-price determinants: - average income of buyers (I); - population (the size of the market) - only for market demand; - prices of related goods - substitutes (Ps) and complements (Pc); - tastes or preferences (T); - expectations of changes in future prices (E); - special influences.
Let's present demand for the goods (for example to a writing-book) in the form of a scale
The increase in demand is displayed on the schedule in the form of moving a demand curve to the right (in our case from D 2 D¢), and accordingly reduction in demand in the form of moving a curve - to the left (from D 2 D¢ ¢).
