Countries with strong codetermination regimes - Austria, Germany, Luxembourg, Denmark, Sweden, and Finland - tend to have low levels of corruption compared to other OECD countries like the US or UK.

"Tellingly, European countries with strong codetermination regimes — Austria, Germany, Luxembourg, Denmark, Sweden, and Finland — tend to have remarkably low levels of corruption, even compared to other OECD countries such as the United States, the United Kingdom, or Japan. We do not claim that these relatively low levels of corruption are solely due to codetermination. Still, they are certainly consistent with the assumption that codetermination helps to prevent “big money” from undermining the rule of law."
