Some of the defining features of entrepreneurship often omitted by standard capital taxation...

We analyze tax competition between large and asymmetric countries and derive conditions under which countries assist foreign authorities in collecting tax revenues via information exchange. It turns out that voluntary exchange of information is a Nash equilibrium between asymmetric countries,...
