Scholz (1998) revealed that there is a second necessary conditionthat the marginal revenue of the wage income tax is negative. In this note we show that (i) thesetwo conditions are not independent, but rather depend both on the slope of the wage curve; and(ii) if Schneider’s condition of a sufficiently flat wage curve is fulfilled, marginal revenue ofwage income taxes must be negative. By implication, both the green tax reform and the sign ofthe marginal revenue of wage income taxes depend on the slope of the wage curve which allowsto distinguish three cases of a tax reform: a) a double dividend for a very small slope of the wagecurve (Schneider’s case); b) failure of unemployment reduction (Scholz’ case) for a very steepwage curve; c) failure of emission reduction for an intermediate case of a wage curve slope.
