假定艾克瑞玛是个“小国”，无法影晌国际价格。该国以每袋10美元的价格进口大豆。其国内需求曲线为：D=400-10P，供给曲线为：S=50+5P。

  确定自由贸易的均衡点。然后，计算并绘出把进口配额限制在50袋时对以下各项的影响：

  a．本国价格的增幅

  b．配额租金

  C．消费扭曲损失

  d．生产扭曲损失

  The nation of Acirema is“small，”unable to affect world prices．It imports peanuts at the price of ＄10 per bag．The demand curve is

  D=400-10P．

  The supply curve is

  S=50+5P．

  Determine the free trade equilibrium．Then calculate and graph the following effects of an import quota that limits imports to 50 bags．

  a．The increase in the domestic price

  b．The quota rents

  c．The consumption distortion loss

  d．The production distortion loss
