You might also want to look at the Heritage Index of Economic Freedom:
Sweden's economy is 70.4 percent free, according to our 2008 assessment, which makes it the world's 27th freest economy. Its overall score is 1.4 percentage points higher than last year, reflecting improvements in trade freedom and financial freedom. Sweden is ranked 14th out of 41 countries in the European region, and its overall score is higher than the regional average.
Sweden enjoys exceptionally high levels of investment freedom, financial freedom, property rights, business freedom, and freedom from corruption. Virtually all commercial operations are simple and transparent. Foreign investment is permitted without government approval, though capital is subject to restrictions in some areas. The financial sector is highly developed, and the Stockholm stock market is open to foreign investment. The judiciary, independent of politics and free of corruption, has an exemplary ability to protect property rights.
In contrast, Sweden has some of the lowest scores worldwide in fiscal freedom and government size. The top income tax rate of 60 percent is one of the highest in the world, and total government spending equals more than half of GDP. The labor market was highly regulated, but reforms have led to a score equal to the world average in labor freedom.
