问题如下：
If household wealth increases, which of the following is most likely to increase?
选项：
A. investment expenses.
B. household saving.
C. consumption expenses.
解释：
C is correct.
Financial and real assets are included in household wealth. If household wealth increases, consumers tend to save less and spend more when it comes to the use of their current income, because they can still meet the demand of wealth accumulation.
考点： household wealth
解析：
个人资产包括不动产、股票和其他证券，其中不动产会占据很大一部分，如果不动产价格上升，个人的资产就会随之上升，此时人们就更愿意去增加消费，而减少储蓄。所以C选项正确，B选项错误。
不动产的增加不会影响投资的变动，因为投资不是个人行为，而是政府和企业的行为，所以A选项不入选。
household wealth专指不动产吗？
