1)minimum wage is above equilibrium. In that case the supply of labour force exceedes demad and quantity employed will decrease(Ld<L'). Such policy will effect welfare of consumers(employers) and suppliers(workers).

Cons.surplus:

before policy- a+b+c

after policy- a

Suppliers surplus:

before policy- d+e

after policy - b+d

So we can see decreace in wellbeing of employers and if b>e, the increase of welbeing of workers.

The market is not in equilibrium, so the economy loses (e+c).

That is for short-run, because in the long-run the market adjusts to new policy.


2)minimum wage is below equilibrium. In that case the demand of labour force exceedes the supply and quantity employed will decrease(Ls<L'). Such policy will effect welfare of consumers(employers) and suppliers(workers).

Consumers surplus:

before policy- a+d

after policy- a+b

Suppliers surplus:

before policy- b+c+e

after policy - c

So we can see decreace in wellbeing of workers and if b>d, the increase of welbeing of employers.

The market is not in equilibrium, so the economy loses (e+d).

That is for short-run, because in the long-run the market adjusts to new policy.
