====<span id=excessivewages>Wage rigidity</span>====
Keynes rejects the classical explanation of unemployment based on wage rigidity, but it is not clear what effect the wage rate has on unemployment in his system. He treats wages of all workers as proportional to a single rate set by collective bargaining, and chooses his units so that this rate never appears separately in his discussion. It is present implicitly in those quantities he expresses in [[wage unit]]s, while being absent from those he expresses in money terms. It is therefore difficult to see whether, and in what way, his results differ for a different wage rate, nor is it clear what he thought about the matter.
