論文提要

Asymmetric information always affects the firm’s decision.  This paper investigates an impact for firm to adopt the eco-label on the abatement of emissions in a market where one of firms has asymmetric information and both firms’ products have an imperfect substitutability.  We find that the market effect of the eco-label may be larger than the cost effect under the case of eco-label on a low abatement of emissions.  At this time, it is benefit for firm to engage the R&D on an eco-label early.  And a large product’s substitutability obstructs the firm without the clean-technology to engage the R&D on an eco-label.  Finally, the overinvestment on R&D in the private section is likely to occur when the monetary value of environmental damage of emissions is small.

研究建議

1.      模型設定應該思考，產品排放減量到某一個程度後，才能取得環保標章。

2.      須思考環保標章在模型設定上是否應該是一個連續的變數。

3.      模型設定，訊息不對稱的設定，使得模型變的雜亂，須檢視訊息不對稱的設定在模型設定中所扮演的角色。

4.      模型求解的過程必須重新檢視。
