经济波动福利成本研究——从技术的推进到思想的拓展

Research on the Welfare Cost of Economic Fluctuations——From Technical Improvement to Idea Expansion

经济波动福利成本研究的早期量化分析认为,经济波动造成的福利成本微不足道,这一结论成为新古典宏观经济学基本观点的一个重要支撑。而在经济波动福利成本研究的后续研究中,这一领域在技术和思想上不断推进,尤其是增长效应、危机效应等新的福利机制不断被挖掘出来,使得我们对经济波动影响社会福利的机制有了更深入了解,也使得早期结论受到相当的质疑。

According to Lucas model of business cycle,eliminating economic fluctuations can not effectively improve social welfare level,which greatly supports the fundamental opinion of neoclassic macroeconomics. With the improvement of technology and idea on business cycle,we presently learn much more on how business cycle affects social welfare,which makes earlier findings quite questionable.
