1F：推 bearching:B 当供给曲线为一价格低於需求曲线的水平线便不成立? 11/10 00:18
2F：→ bearching:就是没有均衡成交量的时候 11/10 00:19
3F：推 bearching:另外C的labor supply是指供给线移动还是供给的量增减呢? 11/10 00:25
4F：推 cotangent37:C选项的labor supply应该是指N(供给量)吧 11/10 00:45
5F：推 cotangent37:这题怎看起来是选错的 11/10 01:05
6F：推 cotangent37:D可以确定是公平赌局嘛? 11/10 01:19
7F：→ longlyg:补充这题是单复选混合题不知道有没有人会 11/10 12:46
8F：推 papapapain:B 当没有成交量的时候,CS不依然是0吗? 11/12 01:21
