Question

Quizplus · Accepted Answer

An increase in income taxes on wages would decrease the incentive for individuals to work, causing the labor supply curve to shift left. This would lead to a decrease in the equilibrium wage rate and employment level, as well as potentially causing some workers to drop out of the labor force. Therefore, it is ambiguous whether the unemployment rate would rise or fall because some workers may choose to drop out of the workforce, which would decrease the labor force participation rate and potentially offset the decrease in labor supply.
