How is the worker’s weekly hour related to wage over the life cycle? The U.S. evidence

Abstract

ABSTRACTThe current study estimates the relationship between weekly hours and weekly wage over the life cycle of a representative sample of workers. Recognizing the endogeneity of these two variables, the study estimates both equations in a simultaneous equations framework and demonstrates that the relationship between weekly hours and weekly wage is not uniform over the worker’s life cycle. These two variables are negatively related when the workers are young and have a positive relationship when they are matured adults. This conclusion remains valid for both men and women. Our robustness check further confirms that workers respond to wage increases differently at different stages of their working career. This has interesting policy implications. Any policy to influence the worker’s hours decision through wage incentive must consider the stage of his/her working career.
