Cointegration in Panel, Spatial and Spatio‐Temporal Models: Some Recent Advances and Applications
回顾了协整概念在面板、空间和时空序列中的最新理论与应用，讨论了无协整原假设被拒绝时的挑战，并简要介绍了协整在气候模型中的应用及气候计量学中的问题。
ABSTRACT Cointegration was originally introduced to describe long‐term dependence between nonstationary time series. In this paper, we review some recent theory and applications of the cointegration concept in the context of panels of time series, spatial series, and spatio‐temporal series. Such an extension offers a number of challenges. In particular, it is not clear what the best approach is if the null hypothesis of no cointegration is rejected. An important part of the paper is a brief section on cointegration in climate models. Applications here have given rise to the new discipline of climate econometrics, and we seek to point out some problems pertaining to panels and cointegration.
