請幫我翻譯一段有關經濟的英文

1.The Firm's Decisions in Perfect Competition

* The firm produces the output at which marginal revenue (price) equals marginal cost .

* If price is less than minimum average variable cost, the firm temporarily shuts down.

* A firm's supply curve is the upward-sloping part of its marginal cost curve above minimum average variable cost.

* An industry supply curve shows the sum of the quantities supplied by each firm at each price.

2.Output,Price,and Profit in Perfect Competition

* Market demand and supply determine price.

* The firm produces the output at which price equals marginal cost.

* In the short run, a firm can make an economic profit,incur an economic loss,or break even.

* Economic profit induces entry. Ecomonic loss induces exit.

* Entry and plant expansion increase supply and lower price and profit.Exit and plant contraction decrease supply and raise price and profit.

* In long-run equilibrium, economic profit is zero.There is no entry,exit ,or change in plant size.

3.Changing Tastes and Advancing Technology

* A permanent decrease in demand leads to a smaller industry output and a smaller number of firms.

* A permanent increase in demand leads to a larger industry output and a larger number of firms.

* The long-run effect of a change in demend on price depends on whether there are external economies (price falls)of external diseconomies(price rises)or neither(price remains constant).

* New technologies increase supply and in the long run lower the price and increase the quantity.

4.Competition and Efficiency

* Resources are used efficiently when we produce goods and services in the quantities that people value most highly.

* When there are no external benefits and external costs,perfect competition achieves an efficient allocation.Marginal benefit equals marginal cost and the sum of consumer surplus and producer surplus is maximized.

*The existence of monopoly,public goods, and external costs and external benefits are obstacles to efficiency.

    1,公司的決定在完全競爭

    *該公司生產的產量在邊際收益(價格)等於邊際成本。

    *如果價格低於最低平均可變成本,該公司暫時關閉。

    *一個公司的供給曲線是向上傾斜的一部分,它的邊際成本曲線高於最低平均可變成本。

    *一個行業的供給曲線顯示了供應量的總和每個公司在每個價格。

    2.Output,價格和利潤在完全競爭

    *市場需求和供給決定價格。

    *該公司生產的產出在價格等於邊際成本。

    *在短期內,企業可以使經濟利潤,承擔經濟損失,或收支平衡。

    *經濟利潤誘使項。 684049的損失誘導退出。

    *進入和擴建增加供給,降低價格和profit.Exit和植物收縮減少供應,提高價格和利潤。

    *在長期均衡,經濟利潤是zero.There沒有入境,出境,或改變工廠的規模。

    3.Changing味和推進技術

    *一個永久性的減少導致需求較小的工業產值和較小的企業數量。

    *一個永久性的需求增加導致了較大的工業產值和更大的企業數量。

    *長遠來說影響了價格上的變化:喬齡山,取決於是否有外部經濟(價格下降)的外部不經濟(價格上漲)或既非(價格保持不變)。

    *新技術,增加供給,從長遠來看降低價格,增加的數量。

    4.Competition與效率

    *有效地使用資源,當我們在生產商品和服務的數量,人們最看重的高度評價。

    *當不存在外部效益和外部成本,完善的競爭達到高效率allocation.Marginal收益等於邊際成本和消費者剩餘的款項和生產者剩餘的最大化。

    *的存在壟斷,公共品,外部成本和外部效
