We are interested in the effect of capital income taxes upon security prices when investors face locally segmented stock markets and a global bond market. Therefore, we analyze an equilibrium model of an economy with binomial uncertainty, an exogenous risk-free interest rate and a representative...

In this paper, I investigate to what extent the cross-country variation in nominal interest rates can be explained as being due to governments' optimal response to economic conditions such as tax collection costs, tax evasion and government consumption needs. In particular, I study the effects...
