This paper assesses the stochastic convergence of relative CO₂ emissions within three different sets of countries over the period 1950-2013. Using the Local Whittle (LW) estimator and its variants we investigate whether relative per-capita CO₂ emissions are long memory processes which, although...

In this paper we examine several approaches to detecting changes in the djustment coefficients in cointegrated VARs. We adopt recursive and rolling techniques as mis-specification tests for the detection of non-constancy and the estimation of the breakpoints. We find that inspection of the...

In more deregulated markets such as the UK, demand forecasting is vital for the electric industry as it is used to set electricity generation and purchasing, establishing electricity prices, load switching and demand response. In this paper we produce improved short-term forecasts of the demand...

This paper aims to shed new light on ”law of one-price” in the United States’ gasoline market over the period June-2003-December-2019. Specifically, we test for convergence of the retail prices of gasoline in di↵erent US PADDs, states and cities using the Local Whittle estimator (LW) and...
