Abstract

The paper shows how tax rate cuts can increase revenues by improving tax compliance. The intuition is that tax evasion has externalities: tax evaders protect each other, because they tie down limited enforcement capacity. Thus, relatively small tax rate cuts, which decrease incentives to evade taxes, can lead to increased revenues through spillovers – creating Laffer effects. Interestingly, cutting de facto tax rates imply increasing de facto or effective tax rates. The model is consistent with the consequences of Russian tax reform, and may provide basis for further thinking about tax rate cuts in other countries.
