Question
The Reliable Aircraft Company manufactures small, pleasure-use aircraft. Based on past experience, sales volume appears to be affected by changes
in the price of the planes and by the state of the economy as measured by consumers' disposable personal income. The following data pertaining to
Reliable's aircraft sales, selling prices, and consumers' personal income were collected:
Year Aircraft Sales
2006
2007
2008
0
0.22
-0.38
-0.22
The arc price elasticity of demand between 2006 and 2007 is:
-8.11
-3.53
525
3.53
450
0
400
The arc income elasticity of demand between 2007 and 2008 is:
Average Price
(Dollars)
16,800
8,000
8,000
Disposable Constant Income
(In constant 2006 dollars, billions)
610
610
Aircraft Sales 2009 Forecast:
Assume that these estimates are expected to remain stable during 2009. Forecast 2009 sales for Reliable assuming that its aircraft prices remain
constant at 2007 levels and that disposable personal income will increase by 7%. Also assume that the arc income elasticity you just computed is the
best available estimate of income elasticity.
Aircraft Sales 2009 Forecast:
590
Forecast 2009 sales for Reliable given that its aircraft prices will increase by 6% from 2008 levels and that disposable personal income will increase by
7%. Assume that the price and income effects are independent and additive and that the arc income and price elasticities you just computed are the
best available estimates of these elasticities to be used in making the forecast.
