斜率和弹性

Slope and elasticity

周三的帖子。 (关税要花多少钱?)提到斜坡和弹性不是同一件事。在这里,我将举几个示例的需求线示例。在第一张图中,我们可以清楚地看到,一个需求线比另一个需求线更陡。我将计算两种不同情况的需求价格弹性。在第一种情况下,我将使用中点公式对每条线的价格从8下降到4,并计算每条线的弹性(较陡的线将具有较低的弹性)。然后,我将计算所有每一行的弹性(在每种情况下,答案将是相同的数字)。在这里,中点公式是:(q2 -q1)/(q2 + q1)次(p2 + p1)/(p2 + p1)/(p2 -p1)计算图。对于较陡的线,这是(8-6)/(8 + 6)次(4 + 8)/(4-8)=(2/14)*(12/4)=(
