Switzerland has a strong legal framework to combat corruption and several authorities are in charge of curbing the levels of it, particularly when it comes to corruption within Swiss financial institutions.[1] Several sources suggest that the country's fight against corruption has been effective.[2][3]
The Transparency International Global Barometer 2013 shows that 58% of the surveyed households believe that corruption has not changed over the past two years, and 28% believe that it has actually increased. The same survey also shows that political parties are considered the most corrupt institution in Switzerland.[4]
Regarding business and corruption, companies do not consider corruption a problem for doing business in Switzerland, and Swiss companies are active in Corporate Social Responsibility that are generally in line with OECD Guidelines for multinational enterprises.[5]
