In Switzerland, the KOF Swiss Economic Institute economic barometer measures the level of optimism that people who run companies have about the performance of the economy and how they feel about their organizations’ prospects. The KOF economic barometer is based on a multi-sectoral design with three modules. The 2014 version comprises 219 indicator variables, which are combined based on statistically determined weights. The most important module is GDP, which excludes construction and banking sectors and accounts for more than 90% of Swiss GDP.
