Real-Time Measurement of Business Conditions
构建了一个框架，利用混合频率的存量和流量数据，通过动态因子模型实现高频甚至实时的经济活动测量，并通过实证和模拟验证了其有效性。
We construct a framework for measuring economic activity at high frequency, potentially in real time. We use a variety of stock and flow data observed at mixed frequencies (including very high frequencies), and we use a dynamic factor model that permits exact filtering. We illustrate the framework in a prototype empirical example and a simulation study calibrated to the example.
