The paper utilizes the methodology proposed by Johnson and Solon (American Economic Review, 76(5), 1117-25, 1986) to examine the impact of job segrega tion on the gender wage gap in the UK in 1991. The results suggest that des pite implementation of the UK 1983 Equal Pay Amendment there remains clear evidence that male/female workers in female dominated jobs continue to earn less for work of 'similar worth' than their counterparts in male dominated jobs within the same firm. This conclusion is insensitive to whether one a dopts an occupation or firm based measure of gender concentration.
