The overall aim of the project is to study the possibilities of the Swedish legal system to combat companies that behave unfairly and thereby threaten free competition. This may involve various types of criminal or socially harmful actions to increase the company's profits, such as corruption, price cartels, tax crimes, human rights violations and environmental crimes. This crime puts good companies at a disadvantage; those companies that respect current legislation and accepted ethical guidelines. The conditions for them to do business are not on the same terms, which in an extreme situation can mean that the good companies are outcompeted. How does the Swedish legal system act to prevent this? To what extent is it possible to maintain a market with free competition between market participants? To answer this question, three complementary methods will be used: document and text analysis, interviews and participant observations. The texts and documents that will be studied include relevant legislation and preparatory work, as well as policy documents produced by the companies and their trade associations. Interviews will be conducted with the Financial Police, the Swedish Economic Crime Authority, the Swedish Prosecution Authority, the Swedish Competition Authority and the Confederation of Swedish Enterprise. Participatory observations will take place at the upcoming trials of two Swedish companies, Telia and Lundin Petroleum.
