This premise is tentatively supported by the quantile regressions of Fournier and Koske (2012) that reveal differences between the bottom and the top of the wage distribution. Low-income workers on temporary contracts indeed earn less than those on permanent ones, and this effect fades for workers that are better paid (Figure 7). Moreover, the cross-country panel analysis tentatively indicates that a larger gap between EPL on regular and temporary contracts is associated with more dispersed earnings (Table 1).
