This paper aims at extracting a common factor from major carbon pricing. For this purpose, we use a Dynamic Factor Model (DFM) for which the unobserved common factors and idiosyncratic noises are potentially non-stationary processes. The two-step Kalman smoother procedure is used to estimate the...

This paper investigates whether a common factor, which can be interpreted as a shadow carbon price, can be extracted from price series in 13 major national and subnational emission trading systems (ETSs). For this purpose, we estimate a dynamic factor model accounting for information...

The purpose of this paper is to provide a flexible parametric methodology to measure nonmonotone relationships between two variables. Indeed, in this context, the Pearson rho measure fails because it is only consistent for linear monotone dependence. Using the well-known return-volume...

In this paper we extend the FMLS-based CUSUM cointegration test (Xiao and Phillips, 2002) for testing the smooth time-varying cointegration null hypothesis. For this purpose we use Chebyshev time polynomials to specify time-varying coefficients under the null. We derive the limiting distribution...
