Abstract: As a Nordic country, Finland is known as a nation with a low level of perceived corruption. This chapter analyzes how corruption is controlled in Finland by asking first, how the different forms of corruption can be identified, including the context and risk areas of corruption; second, what the policies, authorities, and tools for curbing corruption are; and third, how effective are these measures for controlling corruption in Finland. This chapter describes the different aspects of corruption and the corruption control system in Finland, including the level of perceived corruption, anti-corruption regulations, tools and instruments for curbing corruption, and the main watchdog institutions. The main finding is that the control system has worked well so far but it needs reform in the future. The concluding section deals with some challenges facing the control system.
