Total revenue increases or decreases depending on how large the percentage change in the quantity demanded is relative to the percentage change in the price. Hence, the price elasticity of demand determines whether revenue will rise or fall.
Apr 25, 2016 · What happens to the price elasticity of demand when we travel along the demand curve? The answer depends on the nature of the demand curve itself. On a linear demand curve, such as the one in Figure 5.2 , elasticity becomes smaller (in absolute value) as we travel downward and to the right.
In Good 1 - Good 2 space, this means that an increase in the price of grape jelly (good 2) leads to a decrease in the quantity demanded of both goods: that is, the optimal bundle moves down and to the left. In other words, the price offer curve has a positive slope.
Use demand and supply to explain how equilibrium price and quantity are determined in a market. Understand the concepts of surpluses and shortages and the pressures on price they generate. Explain the impact of a change in demand or supply on equilibrium price and quantity.
Explain how and why the value of the price elasticity of demand changes along a linear demand curve. Understand the relationship between total revenue and price elasticity of demand. Discuss the determinants of price elasticity of demand.
Figure 2.17 “Changes in Demand and Supply” shows what happens with an increase in demand, a reduction in demand, an increase in supply, and a reduction in supply. We then look at what happens if both curves shift simultaneously.

A shift in demand means that at any price (and at every price), the quantity demanded will be different than it was before. Following is an example of a shift in demand due to an income increase. Step 1. Draw the graph of a demand curve for a normal good like pizza. Pick a price (like P 0). Identify the corresponding Q 0. See an example in ...
