Inelastic Inversions

To reduce corporate inversions, where US firms buy foreign firms to reduce taxes, in 9/14 the Treasury attempted to curb such deals by making them more difficult. That said, in the 16 months since 9/14 there have been 12 corporate inversions, about as many as occurred in the 16 months prior to the more stringent regulations. Maybe focus on corporate tax reform before there are no US domiciled firms left?
