The five countries with the worst pensions climate are Belgium, Slovenia, Greece, France & Malta with the best three being Denmark, Estonia & Ireland. This ranking is generated using four broad macroeconomic categories, only one of which refers to occupational pensions. The categories are evenly weighted. The low weight of occupational pensions makes sense if seen in the context of the barometer's purpose.
The approach is interesting and expandable. Naturally, individual categories and variables are subject to the authors' discretion, but this type of helicopter view is often useful. Unfortunately, important countries are currently missing from the survey's assessment, such as Switzerland, which is certainly an important potential location, or the new EU members Bulgaria & Romania.
