1F：推 bearching:B 當供給曲線為一價格低於需求曲線的水平線便不成立? 11/10 00:18
2F：→ bearching:就是沒有均衡成交量的時候 11/10 00:19
3F：推 bearching:另外C的labor supply是指供給線移動還是供給的量增減呢? 11/10 00:25
4F：推 cotangent37:C選項的labor supply應該是指N(供給量)吧 11/10 00:45
5F：推 cotangent37:這題怎看起來是選錯的 11/10 01:05
6F：推 cotangent37:D可以確定是公平賭局嘛? 11/10 01:19
7F：→ longlyg:補充這題是單複選混合題不知道有沒有人會 11/10 12:46
8F：推 papapapain:B 當沒有成交量的時候,CS不依然是0嗎? 11/12 01:21
