Abstract

In this paper, we test the stochastic properties of daily accumulated number of confirmed cases of Covid-19 (ANCCC) in the 20 countries using Fourier quantile unit root test. The results indicate that the negative shocks to ANCCC series have long lasting effects in all countries (except China) and big positive shocks have permanent effects in some countries. Our results have important policy implications.
