问题如下：
If wages were automatically adjusted for changes in the price level, the short-run aggregate supply curve would most likely be:
选项：
A.flatter.
B.steeper.
C.unchanged.
解释：
B is correct.
The slope of the short-run aggregate supply curve reflects the extent to which wages and other input costs adjust to the overall price level. Automatic adjustment of wages would mitigate the impact of price changes on profitability. Hence, firms would not adjust output as much in response to changing output prices—the SRAS curve would be steeper.
考点：短期供给曲线
解析：如果工资水平可以跟随物价及时调整，那么短期供给曲线形状就会像长期供给曲线靠近，变得更加陡峭。
因为此工资及时调整，就可以及修正生产成本，修正后的生产成本没有实质性的改变，厂商就不会改变其产量，这在图形上就表现为供给曲线变得陡峭。
对AS curve来说，P的变化只会导致AS curve move along，不会导致它shift。所以这道题什么是更陡峭呀
