问题如下:
In an equilibrium economy, if there is an increase in aggregate demand in the short run, the least likely effect is
选项:
A. the price level in the market will not be affected.
B. actual GDP is larger than potential GDP.
C. working hours of labors is increasing.
解释:
A is correct. Due to a short-run increase in aggregate demand, the equilibrium GDP level is larger than full-employment GDP. Labors will work overtime. The price level in the market will increase.
考点:总需求
解析:
由于总需求的短期增长,此时,短期需求曲线向右上平移,与供给曲线产生的新的交点均衡GDP有着更高的纵坐标和更大的横坐标,这代表均衡GDP水平大于充分就业GDP水平,并且市场上的价格水平将会提高。所以B选项不入选,A选项入选。
总需求短期增长,为了暂时提高产能,工人可能会加班。所以C选项不入选。
我理解的是,Actual GDP是指AD向右移后,更大的Y点。但它还是xiaozu小于potential GDP呀。因为potential GDP是长期的嘛
