Wrong! - An upward-sloping and a downward-sloping labor supply curve imply that workers always increase and decrease labor hours, respectively, when the wage rate rises. In the Netherlands, at high wages, workers decrease labor hours when wages rise, so the curve is not forward bending.
Correct! - As wages rise, labor hours first increase, but at high income levels, as in the Netherlands, further wage increases lead workers to choose more leisure and fewer labor hours, making the labor supply curve backward bending.
