When prices are low，people will buy more，and when prices are high，they will buy less．Every shopper knows this．But at the same time，producers want higher prices for their goods when they make more goods．According to the economic（经济的）point of view，changes in the prices of goods cause changes in supply and demand． As is shown in the graph（图表），people buy fewer shoes as the price of shoes goes up．On the contrary，a decrease in the price causes an increase in demand．
