In AS-AD model (assume sticky- wage model, perfect competitive market) 中,
labor demand 是 sum of Marginal product of labor(MPL) 的curve ( diminising), real wage 是等於MPL
, 如果現在 AD shit to the right, output 多左 price 上升的情況下,adjustment 係 wage都 上升 由於worker negotiate their wage.
SRAS shifts up 去返equilibrium.
我想問的問題是 price 上升點解唔駛考慮firm enter?
