Contemporaneous causality among office property prices of major Chinese cities with vector error correction modeling and directed acyclic graphs

Abstract

Purpose This study aims to investigate dynamic relations among office property price indices of 10 major cities in China for the years 2005–2021. Design/methodology/approach Using monthly data, the authors adopt vector error correction modeling and the directed acyclic graph for the characterization of contemporaneous causality among the 10 indices. Findings The PC algorithm identifies the causal pattern, and the linear non-Gaussian acyclic model algorithm further determines the causal path from which we perform innovation accounting analysis. Sophisticated price dynamics are found in price adjustment processes following price shocks, which are generally dominated by the top tier of cities. Originality/value This suggests that policies on office property prices, in the long run, might need to be planned with particular attention paid to the top tier of cities.
