The ESRI in a paper entitled "Male-Female Wage Differentials: Analysis and Policy Issues" which was jointly commissioned by my Department and the Employment Equality Agency and was published last year, indicated that women's hourly earnings are approximately 80 per cent of men's, when all sectors of industry are taken into account. The report sought to identify the factors which contribute to the persistent sizeable earnings differential between men and women and to isolate residual factors which may be the result of discrimination.
Half the 20 per cent wage gap was explained by the ERSI as reflecting productivity-related factors, such as experience and a sustainable rise in length of women's employment during their lifecycle was seen as the most effective way of reducing this portion of the wage gap. The remaining 10 per cent gap could not be explained in detail. This reflects a lack of knowledge on the impact of wage determination process and very possibly the existence of discrimination. Measures to address both the length of service of women in the labour market and discrimination are being pursued on a number of factors.
