问答题 如果上题中所有资产的美元价格同时上升10/%,实际收益率将是多少?
   What would be the real rates of return on the assets in the preceding question if the price changes described were accompanied by a simultaneous 10 percent increase in all dollar prices?
【正确答案】实际收益率≈名义收益率-通货膨胀率,在本题中所有资产的美元价格同时上升10/%,可视为通货膨胀率为10/%。
   因此,对于a而言,实际收益率=25/%-10/%=15/%;
   对于b而言,实际收益率=20/%-10/%=10/%;
   对于c而言,实际收益率=2/%-10/%=-8/%。
【答案解析】
