The German government recently decided to purchase stolen data revealing tax avoiders hiding money in Swiss bank accounts. This is a risky move diplomatically, but, for Germany, the gains from tackling this tax flight appear to outweigh the risks. It is also illustrative of the proliferating efforts by individual governments and the international community to clamp down on tax flight: the loss of tax revenue due to cross border tax evasion or avoidance.

However, the recent spat between Switzerland and Germany is merely the tip of the iceberg; symptomatic of what is one the most serious systemic failures of our time: the lack of intergovernmental cooperation on cross-border financial matters.
