Wages Across Markets In explaining wage differences for different types of labour, we can use the conventional supply and demand framework. Even with its limitations, the model highlights the fact that wages are determined by BOTH supply and demand factors in the market for a given type of labour. A key implication of the competitive supply and demand model is that wages are equal to the Value of the Marginal Product of Labour, i.e., Differences in wage are therefore driven by differences in VMP. And people with the same VMP should be paid the same wage. 3 W = VMP

But improbable We now move to the question of why different groups (or people with a particular group characteristic) may earn different wages or incomes. Our focus will be on male-female differentials, with some attention to racial wage differentials (especially the Black-White differential in the United States).
