Source: NPD Market Research Company. The reported sales for each brand is the sum over a 41-month period from January 2003 to May 2006. The sales volume of the overall market is calculated upon observations of all P&S cameras by 46 brands listed in the original dataset, which takes up above 80% of overall sales in the US market during this period.

Figure 5a. Price elasticity of demand excluding the age variable
Figures 5a and 5b plot the price elasticity of demand, where the former excludes the age variable but the latter includes it. All observations are organized into 5 groups according to their ages, i.e. age 1~6, age 7~12, age 13~18, agel9~24 and age > 24. Each group is plotted in a separate panel. The scatters are associated with individual elasticities, while the belts show the median predictions.
