We propose a sieve bootstrap framework to conduct pointwise and simultaneous inference for time-varying coefficient regression models based on a nonparametric local linear estimator. The asymptotic validity of the sieve bootstrap in the presence of autocorrelation is established. We find that it...

While previous studies focus on linear unit root test to study the convergence of carbon price in some developed countries and the results might be biased due to the lower power of these linear unit root tests. China provides an interesting arena to investigate its carbon price convergence due...
