1.假設某一條河川的上游為一家化工廠，下游為魚蝦養殖場。假設化工廠生產化工產品
（Q）的邊際利潤為10（MR＝10），邊際成本為Q（MC＝Q）。由於化工廠生產化工產品會
同時排放污水於河中，將導致魚蝦養殖場有邊際損失Q（MDC＝Q），試回答下列問題。
（請利用數學搭配圖形分析）
（1）請問社會福利最適時，化工產品的生產數量應該為多少？
（2）請問追求利潤極大化時，工廠不考慮外部性的問題，則化工產品的生產數量為多少？
（3）請問當和流得所有權屬於化工廠，經過化工廠與魚蝦養殖場的談判與協調，則最適
的生產數量為多少？為什麼？（有完整說明才給分）
（4）請問當河川所有權屬於魚蝦養殖場，經過化工廠與魚蝦養殖場的談判與協調，則最
適的生產數量為多少？為什麼？（有完整說明才給分）
2.請證明某一獨佔廠商短期利潤為零時，只要該廠商的總固定成本（TFC）大於零，則該
獨佔廠商將繼續營運。（請用圖形分析，要有文字解釋）
3.某產業之需求函數為Q＝100-P，且生產產品之長期邊際成本值LMC＝10，試問以下問題
。（請利用數學搭配圖形分析）
（1）若此產業為完全競爭時，市場均衡價格與產量。
（2）若此產業為完全獨佔時，獨佔廠商之最適定價與產量。
