摘要

We show how different data types (stocks and flows) and temporal aggregation affect the size and power of the dynamic ordinary least squares residual-based Kwiatkowski-Phillips-Schmidt-Shin (KPSS) test of the null of cointegration. Size may be more effectively controlled by setting the minimum number of leads equal to one - as opposed to zero - when selecting the lag/lead order of the dynamic ordinary least squares regression using aggregated data, but at a cost to power. If high-frequency data for one or more series are available - that is, the model has mixed sampling frequencies - we show how to effectively utilize the high-frequency data to increase power while controlling size.
