Conditional Relative Price Variance and Its Determinants: Open Economy Evidence from Germany
基于开放经济多市场均衡模型，用ARCH方法估计条件相对价格方差，检验其与国内外货币及实际冲击的正相关关系，以及对正常产出的负向影响，德国数据支持这两个假说。
The authors present empirical tests of two hypothesis derived from an open economy version of the multimarket equilibrium model. The first hypothesis holds that the conditional relative price variance is positively related to the variance of domestic monetary and foreign nominal and real shocks. The second hypothesis claims a negative impact of an increase in conditional relative price variance on normal output. In contrast to earlier studies, the authors use direct measures of conditional relative price variance based on ARCH estimates. The authors' results show that both hypotheses are consistent with German data.
