That austerity is a counterproductive economic policy in a situation of economic recession can be seen, rightly, as a “Keynesian critique.” Keynes did argue—and persuasively—that to cut public expenditure when an economy has unused productive capacity as well as unemployment owing to a deficiency of effective demand would tend to have the effect of slowing down the economy further and increasing—rather than decreasing—unemployment. Keynes certainly deserves much credit for making that rather basic point clear even to policymakers, irrespective of their politics, and he also provided what I would call a sketch of a theory of explaining how all this can be nicely captured within a general understanding of economic interdependences between different activities... I am certainly supportive of this Keynesian argument, and also of Paul Krugman’s efforts in cogently developing and propagating this important perspective, and in questioning the policy of massive austerity in Europe.
But I would also argue that the unsuitability of the policy of austerity is only partly due to Keynesian reasons. Where we have to go well beyond Keynes is in asking what public expenditure is for—other than for just strengthening effective demand, no matter what its content. As it happens, European resistance to savage cuts in public services and to indiscriminate austerity is not based only, or primarily, on Keynesian reasoning. The resistance is based also on a constructive point about the importance of public services—a perspective that is of great economic as well as political interest in Europe. (en) |
