‘New Keynesian’ and New Classical microfounded DSGE models do not incorporate such a basic fact of reality as involuntary unemployment. Of course, working with microfounded representative agent models, this should — as argued in my paper Micro vs. macro — come as no surprise. If one representative agent is employed, all representative agents are. The kind of unemployment that occurs is voluntary, since it is only adjustments of the hours of work that these optimizing agents make to maximize their utility. In this model world, unemployment is always an optimal choice to changes in the labour market conditions. Hence, unemployment is totally voluntary. To be unemployed is something one optimally chooses to be.
To Keynes it was a sad fact of the world that not all unemployment is voluntary. But obviously not so to New Classical and ‘New Keynesian’ economists.
