Therefore, he made the specific assumption of short-period so as to concentrate on the problem at hand. Keynesian theory, on the other hand, is more realistic as it considers the economies of less than full employment also. Most of the modern economists agree with the concept of Keynes. In contrast, Keynesian theory (and its modern cousins) say that while "real recessions" in the above sense may indeed exist, there are also "nominal recessions": these are recessions caused by "less spending" (for instance, if you're working with MV = PY, they are recessions caused by a fall in V).
