This paper explores zero lower bound (ZLB) economics. The ZLB is widely invoked to explain stagnation and it fits with the long tradition that argues Keynesian economics is a special case based on nominal rigidities. The ZLB represents the newest rigidity. Contrary to ZLB economics, not only...

This paper provides a critique of zero lower bound (ZLB) economics which has become the new orthodoxy for explaining stagnation. ZLB economics is an extension of pre-Keynesian economics which attributes macroeconomic dysfunction to rigidities and market imperfections. The ZLB is the latest...
