A binding minimum wage set above the equilibrium wage in a competitive labour market tends to:
A. Create surplus labour, showing up as unemployment among workers at that wage✓ 答案
B. Create a labour shortage at the higher wage
C. Leave the quantity of labour employed unchanged
D. Raise both the wage and the level of employment

A minimum wage above equilibrium is a floor: Qs of labour > Qd of labour. Employment is determined by the smaller side, so the surplus shows up as unemployment or shorter hours.
