A change in price causes a movement along the Demand Curve. In this lecture, we will examine how to analyze supply and demand curves and the impact changes in market conditions and government policy can have on market equilibrium. Make sure you write your name So, a decrease in demand will cause both the equilibrium price and the equilibrium quantity to decrease.

B) if the total revenue from sales of A rises, we know the demand for A is elastic. Whereas supply and demand were in equilibrium at Q E1 at the initial price of $3, the demand shift has caused Q D > Q S. As discussed, this causes a shortage (see left side of Figure 3.6e).
