问题如下：
Which of the following is most likely to increase after an increase in aggregate real personal income?
选项：
A.Equity prices
B.Building permits for new private housing units
C.The ratio of consumer installment debt to income
解释：
C is correct.
Aggregate real personal income is a coincident indicator of the business cycle and the ratio of consumer installment debt to income is a lagging indicator. Increases in the ratio of consumer installment debt follows increases in average aggregate income during the typical business cycle.
考点：Economic Indicators
解析：Aggregate real personal income 是一个同步指标，它的上升意味经济的向好。那么依据题意，我们要选一个证实经济向好的滞后型指标，C选项正确。
A和B都是领先型指标，所以不入选。
是贷款的比例会上升吗？就是经济好了，然后大家开始借钱了？
