International Business Cycles and Financial Integration
利用时间序列潜因子模型的新方法，研究六个发达国家的商业周期及其与股市价格的关系，发现各国商业周期虽不同但具有一致性，且国际经济活动一致性在浮动汇率时期增强，但股市与商业周期的一致性较弱。
Recently developed methods in the analysis and measurement of latent factor models for time series are utilised to study international business cycles and their relationship to international stockmarket price behaviour. An advantage of these methods is that the duality properties between time domain and frequency domain approaches for investigating the properties of time series can be exploited to identify and model business cycles. The empirical results show that the six countries studied, which include the United States, Australia, Canada, United Kingdom, Germany and Japan, exhibit coherent national business cycles, although these cycles are not all alike. It is also found that international coherence in economic activity has increased in the flexible exchange rate period, although it is not as strong as it is for the national business cycles. The coherence between stockmarket prices and business cycles is not strong, both nationally and internationally, but international stockmarkets appear to show greater mutual coherence than do the corresponding economies.
