But labour taxation was especially high on low-wage workers, with a tax wedge about six percentage points above the OECD average for minimum wage earners (Figure 3.6, Panel B). This depends on a number of factors, namely: i) the presence of a net wage floor (i.e. a binding minimum wage), ii) the extent to which workers value social protection or public services provided by taxes, iii) the relative bargaining power of employers and employees, and iv) the relative generosity of possible replacement revenues (OECD, 2008|3i|). The effects of labour taxes on labour demand are thus likely to be particularly large at low wage levels.
