The New Keynesian Synthesis
回顾了过去五年在名义价格刚性微观基础方面的突破，总结了当前对名义刚性的理解，并指出未来研究方向，对宏观经济学研究者有参考价值。
The new Keynesians made more rapid progress in understanding the microeconomics of unemployment than in understanding the microeconomics of nominal price rigidity. But the past five years have seen important breakthroughs in this second area. This paper will describe these breakthroughs, discuss our current understanding of nominal rigidity, and assess the work that remains to be done.
