中文摘要 | 近幾年,有不少的經濟學者探討了在未確定需求條件下的廠商投入與產出之決策行為。雖然投入決策與產出決策之間有密切的關係,但他們卻很少在其相互作用下來探討廠商的決策行為。因而,本文就是要在投入與產出之詞以及兩種投入之間的相互作用下,來探討廠商的決策行為,而得到了與相關論文相類似或更為明確及一般化的結論。通常,風險驅避廠商會比風險中立廠商生產更少的產品及投資較少的資本。風險中立廠商會利用滿足期望邊際收益等於邊際資本成本之條件來決定其最佳資本投資,但風險驅避廠商在最佳資本投資時的期望邊際收益卻會大於邊際資本成本。在絕對風險驅避為漸減的假設下,資本成本的增加及風險的邊際衝擊均會使得風險驅避廠商減少其資本投資額及產量。對於風險中立廠商來說,只要產品的期望價格不變,則它的決策就不會受到風險邊際衝擊的影響,但它的投入及產出卻會隨著資本成本的增加而減少。 |
英文摘要 | RecentLy, several economists have discussed the firm's behaviors about imput and output decisions under demand uncertainty. Most of their papers separately examine the input and output decisions, though these decisions are very much related. In this paper, we investigate the decision behaviors of the firm facing uncertain demand under the interaction of input and output decisions. We can obtain some results that are similar to or more explicit than those examined in some other related papers. In general, the risk-averse firm produces less output and invests less capital than the risk-neutral firm. The risk-neutral firm decides its optimal capital investment by equating the expected marginal revenue to the niarginal capital cost, bùt the risk-averse firm requests more the expected marginal revenue than the marginal capital cost at the optimal capital level. Under the assumption of decreasing absolute risk aversion, an increase in capital cost and a marginal increase in uncertainty will both cause the risk-averse firm to decrease its capital investment and output level. For the risk-neutral firm, its decisions may not be affected by the uncertainty impact as long as the expected price of the output unchanges, but its input and output will decrease as the capital cost increases. |
