One way to estimate the importance of SOEs (State Owned Entreprises) in a given economy is to take their revenues and simply transpose them onto the overall economy as measured by GDP. So I have applied the exercice to my home province of Quebec in Canada (and I intend to begin comparisons soon). This first set is available is my “data sets” section and will be updated regularly to include other nations, provinces or states.
As an interesting aside, everyone interested in the issue of privatization ought to read Netter and Megginson’s 2001 article in the Journal of Economic Literature concerning the results of privatization and the trends with regards to SOEs. It is void of all jargon that might terrorize non-economic readers and is quite instructive with regards to privatization.
