需求价格弹性与收益的辨析

对于不同的需求价格弹性 ,价格升降能否为企业带来更大的损益 ,在价格的升降幅不超过阈值 1Ed- 1范围内存在一种必然的联系 ;但升降幅一旦溢出阈值 ,那种弹性与正收益的必然联系就不复存在了。在表述单位弹性时 ,不应将注意力放在价格变动引起的收益变动上 ,而应该表明价格定在单位弹性点上 ,即企业在单位弹性点上组织生产 ,其收益达到最大。以利用弧弹性公式计算的需求价格弹性作价格决策时应特别慎重

Analysis of price elasticity of demand and income

There exists a question whether price up and down can bring enterprises greater profits or losses based on different price elasticity of demand( E d ), the a rticle points out that there exists a kind of necessary relationship on condition of t he extent of price up and down not beyond the threshold 1 E d -1. There is no necessary relation between elasticity and positive income if the value of price up or down overflows the threshold. When expressing unit elasticity, we can neglect income changes resulting from price changes. Meanwhile, the article holds that enterpr ises will get the greatest incomes when they set suitable price on the point of unit elasticity, on which they organize production. We should be more careful wh en making price decision by means of curve elasticity calculating Ed.
