The measure of wage provided refers to hourly labour cost, or gross earnings, i.e. includes labour income taxes and social security contributions as well as fringe benefits. In particular, it accounts for bonuses and executive compensation. Wage premia are calculated as the average of the wage premium for each triplet consisting of one age bracket, one education level and the gender, weighted by the number of financial sector employees in the triplet. Hence, the aggregate measure uses the relative frequency of financial sector employees in the different triplet categories.
