供给价格弹性是指供给量相对价格变化作出的反应程度，即某种商品价格上升或下降百分之一时，对该商品供给量增加或减少的百分比。
多年以前我曾以一种完全价格弹性和固定货币供给的假想世界模型对此做过解释。
Many years ago I tried to explain this by considering a hypothetical world of perfectly flexible prices and a fixed money supply.
通常，s(p)表示单位价格p变动时供给量的变动，而供给弹性表示为h（来自古希腊字幕的第七个，因为第五个已经被选）。
Formally, if s(p)gives the quantity supplied for each price p, the elasticity of supply, denoted h (the Greek letter “eta”, chosen because epsilon was already taken) is
对居民要素交易机会的限制越大，要素保留价格越低，供给弹性越小，要素收入份额越小。
Besides, the more constraint put on opportunities of factor marketing, the less the reservation price and the elasticity of supply was, therefore the share of factor income became less.
