This paper studies how corporate tax hikes transmit across countries through multinationals’ internal networks of subsidiaries. We build a parsimonious multicountry model to underscore two opposing spillover effects: While tax competition between countries generates positive investment...

We study the link between a country's institutional quality in tax collection and its optimal corporate tax policies in a model of heterogeneous multinationals that can shift income using both debt and transfer prices. Countries with weak institutional quality can be made worse off adopting...
