物理化学实验改进——液体饱和蒸气压的测定

对传统的物理化学实验之一——液体饱和蒸气压的测定进行五点改进:1、将有毒的苯改成无毒的乙醇;2、将不易读数的水银温度计改成简单易读的数据温度计;3、将水银U形压力计改成DP-A精密数字压力计;4、将普通的缓冲瓶改成不锈钢缓冲储气罐;5、用Excel处理实验数据代替手工作图。如此这些既体现绿色环保又提高实验结果的准确性。

Estimating Open Economy New Keynesian Phillips Curve for Korea

We estimate the open economy new Keynesian Philips curve (NKPC) to characterize the inflation dynamics of Korea. While recent studies show that the NKPC holds for the pre‐currency crisis period, the empirical evidence is inconclusive for the post‐crisis period. Has globalization increased the role of global factors relative to domestic factors? Can labor income share still serve as a good measure of real marginal cost following the structural break? To address these issues for the post‐crisis period, we use two types of open NKPC: the relative prices model and the incomplete pass‐through model. The estimation of both models indicates that the forward‐looking behavior is important, and its role is reinforced in an open economy specification. Both NKPC models also show that the external factors are more relevant inflation drivers than the domestic factors.
