Policy Possibilities of the New Macroeconomics

从1999年4月到2001年12月，我们举办了23次宏观经济学研讨会，邀请了许多活跃在这一领域的研究人员。参加该项目的研究人员通过研讨会从这些研究人员那里受益匪浅。人们一致认为，财政政策不应经常用于稳定政策，例如降低失业水平，而应用于内部化市场失灵。我们得出了以下结论：应该使用货币政策来稳定经济;对于劳动力市场，根据工人纪律模型，退休金越多，失业成本越高。研究结果还表明，失业救济的发放时间长短对失业政策的制定具有重要意义，因此，期望的协调是失业政策制定的重要内容。协调失败可能导致就业和产出水平低下。但到目前为止，我们在这方面还没有很好的政策建议。这是一个很有前途的课题，为未来的研究。

We have had Macroeconomics Workshop 23 times from April 1999 to December 2001 and invited many researchers who are active in this field. Investigators who have taken a part of this project have been benefited from these researchers through the workshop.It is agreed that fiscal policies should not be used for the stabilizing policies frequently, for example, for reducing the unemployment level but should be used for internalizing market failures. We have reached the following conclusion: Monetary policies should be used to stabilize the economy.As for the labor market, it is shown that the larger retirement money the higher the cost of unemployment according to the worker discipline model. It is also shown that how long workers can get unemployment benefits is very important for unemployment policies.We have come to conclude that coordination of expectation is very important. Failures of coordination may lead to low levels of employment and output. However, we have not had good policy recommendations in this respect until now. This is a promising subject for future researches.
