good afternoon,
I am analyzing the convergence of pollutant emissions
between 74 countries.
A possibility is to check the presence of a unit root
in the ratio emissions/mean of emissions. However,
this analyse has some drawbacks.
Therefore, it is better to analyse the presence of a
unit root in each pair (emissions of country i -
emissions of country j).
This study is based on the paper of Pesaran (2007) " a
pair-wise approach to testing for output and growth
convergence", Journal of Econometrics, vol 138, pp.
312-355.
Tahnk you for your help.
