Solution to Quiz 3

 

If the city increased the bus fare, the quantity demanded of bus rides would decline and the number of riders would be expected to decline.  Total revenues would rise, however, if the price elasticity of demand for bus service were less than one, in which case the city’s losses would decline.  Alternatively, if the price elasticity of demand for bus service were greater than one, the city’s revenues would decline and its losses would increase if it raised the bus fare.  The opposite applies to a decrease in the bus fare—it would decrease revenues and increase losses if the price elasticity of demand were less than one and increase revenues and decrease losses if the price elasticity of demand were greater than one.  In the intermediate case of a price elasticity of demand for bus service equal to one, a price increase or decrease would have no effect on total revenues and hence would have no effect on the city’s losses. The income elasticity of demand indicates nothing about the effect of a price change on the quantity demanded or total revenues.
