Corruption is widespread, and exists more or less in all countries in the world. It is today high on the international political agenda as a result of globalization and is seen as a serious impediment to development. In 2011, Sweden scored 9,3 out of 10 on the Transparency International corruption index which gave the country a 4th place of 182 on the list. This refers to a rather low corruption. Although Sweden is a country with low level of corruption that does not mean that it is completely corruption-free. During the last decade corruption scandals in Sweden has been revealed. At the national level is the bribe scandal with Systembolaget in 2004 where a total of 92 persons were prosecuted, by foremost the largest. On the municipal level is the bribe scandal in Gothenburg maybe the one freshest in mind. There is a reason to not completely dismiss corruption as an existing problem in Sweden. Often the measurements on corruption in Sweden are made at a national level. Therefore, this paper is made to complement national research with a study on the municipal level, to determine if there is a variation in the case of Sweden. The paper is based on the theory that a favorable temptation structure can serve as an explanation for the appearance of corruption. Potential underlying variables to the favorable temptation structure is also examined. A qualitative method is used in the study of corruption in municipalities in the form of a comparative case study. Two municipalities with corruption are examined and one without. A quantitative method is used in the study of the potential underlying variables to the temptation structure. Result show that corruption is a complex problem and that there is hard to find a general explanation to why corruption exists in municipalities.
