A literature review of the forms of age discrimination: an economic perspective

Long Description for Figure 6

Variance-based discrimination

Figure 6 illustrates possible distributions of the job performance of younger and older workers using two bell curves with normal distributions. The bell curve for older workers presents the hypothesis that their job performance has a smaller variance but same average as older workers. Older workers have the same average job performance as younger workers. The higher variance in the job performance of older workers implies that the two tails of their job performance in the bell curve distributions are fatter to account for a larger number of high performing workers in the right tail and workers whose performance is falling away in the left tail.
