问题如下：
Which of the following statements about potential real GDP is least appropriate?
选项：
A.Technology advance and innovation will increase the potential real GDP.
B.The improvement of money wage rate will increase the potential real GDP.
C.An increase in Labor and capital input will increase the potential real GDP.
解释：
B is correct. Money wage rate will affect the short-run aggregate supply but not the long-run, therefore it cannot increase the potential real GDP. Technology, labor input and invested capital will increase the potential real GDP.
考点：
解析：货币工资率影响的是短期总供给，而不是长期总供给，因此不能增加潜在的实际GDP。技术、劳动力投入和投资资本的增加会提高潜在的实际GDP。所以B选项入选。
这里的货币工资率是W/P吗？还是名义工资率？
有一个公式：
％ΔY=％ΔA+WL％ΔL+WK％ΔK 这个里面不就体现出工资率对于经济增长的影响吗
