Assume that labor demand for engineering is perfectly inelastic and is given by the equation L^d=300, while the supply curve for engineering is given as L^s=210 +10W represents the hourly wage rate. (a) what is the level of employment, wage and, unemployment rate if the minimum wage is set at $7.25 per hour? (b) If the minimum wage is raised to $12 per hour, how many workers lose their job? what is the unemployment rate?
