This paper investigates the determinants of job satisfaction using data from the National Educational Longitudinal Study. The determinants of interest include actual pay, relative pay, hours of work, job autonomy and several personal characteristics. We also investigate the determinants of satisfaction with pay conditional on a worker's satisfaction with other domains of job satisfaction, such as satisfaction with job security. We find that relative pay is statistically significant but that its effect on satisfaction with pay is relatively small. Job autonomy has a powerful influence on satisfaction with pay. So too does being black.
