Using occupational wage structure survey(1996-2006) by Korean ministry of employment and labor, we explored the effect of performance based pay on the pay dispersion within firm. Pay dispersion is defined as the within-firm variance of wage residuals after controlling the individual characteristics in the labor market. The results show that introduction of performance-based pay system increases the level of pay dispersion significantly. However, The relationship of employees' ratio who receive performance-based pay and the level of pay dispersion is an inverted U-shaped($\bigcap$).
