if wages are too high, labour supply will be high but labour demand will be low because firms don’t want to pay high wages to more workers - leads to unemployment
in a competitive market, workers will have to accept lower wages or even go without a job, meanign that the wage rate will fall to the market clearing wage rate
The market clearing wage rate is the wage level where the quantity of labor supplied by workers equals the quantity of labor demanded by employers
if wages are too low labour demand will be high but supply will be low. leads to excess demand, so there will be a labour shortage because workers will not work if they are not paid enough to do so
When there is a labourshortage, firms will have to pay workers more to convince them to work so the wage rate will rise towards the market clearing wage
