| 摘要: | 本文考慮廠商提高企業社會責任程度的時候，消費者會提高對廠商產品的願付價格，故假設市場上有兩家廠商，在進行價格競爭或數量競爭的情況之下，探討廠商決定企業社會責任程度的時候，對於價格和消費者剩餘造成的影響。本文為兩階段賽局，第一階段為董事會決定企業社會責任程度；第二階段為廠商經理人決定產品的訂價或產量。研究結果發現在價格競爭時候，企業社會責任程度較高的廠商提升企業社會責任程度，會使得兩家廠商產品的價格提升和消費者剩餘可能會下降或上升。此外，企業社會責任程度較低的廠商提升企業社會責任程度的情況之下，兩家廠商產品的價格反而會下降及市場上的消費者剩餘會上升；在數量競爭時候，當一家廠商的企業社會責任程度提升時，該家廠商的產量和價格會提升，而另一家的產量和價格則會下降。此外，廠商提升企業社會責任程度，會使消費者剩餘增加。;This paper has discovered the positive relationship between a firm’s Corporate social responsibility (CSR) and the price that a customer is willing to pay for that firm. We assume there are two firms in the markets and discuss how price and quantity competition. We try to find the equilibrium cooperation in two-stage games. The first stage discuss how board of directors would decide their product’s price and quantity. Our result finds that both price in two firms will rise and the consumer surplus may rise or fall while the firm with higher level of CSR decide to prove its CSR under price competition. Moreover, both price will fall and the consumer surplus will rise when the firm with lower level of CSR increase its level of CSR. However, when one firm increase its level of CSR, the price and the quantity of its product will fall. Besides, the consumer surplus will increase if firms are deciding to rise its level of CSR. |
