Abstract

This paper discusses frequency and quantile-varying linkage between economic policy uncertainty (EPU) and green bond index (GBI) using wavelet multiscale decomposition and quantile-on-quantile regression approaches. We construct nine different time frequency combinations of short-term EPU and long-term GBI and find that dynamic coefficients exist for their relationship across different quantiles. For the same cases, the corresponding coefficients even change from positive to negative or conversely, further proving the unstable linkage related to different quantiles and frequencies. The major contribution of this study is that time frequencies and quantile-varying analysis are used simultaneously. In addition, China’s economic reform and complex external economic shocks make it a case worthy of study. Furthermore, this work indicates a nonlinear link, which adds to the theoretical foundation of EPU and GBI. Thus, authorities should stabilize their economic policy, avoid drastic policy changes and increase policy transparency, which can strengthen investors’ confidence in the green bond market.
