In the last 20 years, the share of top incomes in Switzerland has risen, while
exhibiting large variations. Switzerland is similar to European countries for the top
1% but closer to the U.S. for higher top income groups. With the synthetic control
method we close a time gap in the tax data, exploiting the fact that Swiss cantons
changed their tax system at different points in time. Using social security data
which cover all top labor incomes, we document the growing importance of labor
compared to capital incomes among top income earners in Switzerland.
