Maximum likelihood estimation (MLE) of stochastic differential equations (SDEs) is difficult because in general the transition density function of these processes is not known in closed form, and has to be approximated somehow. An approximation based on efficient importance sampling (EIS) is...

Tax competition has long been studied using panel models. According to this approach, each country's tax rate is assumed to depend on a weighted average of the tax rates applied in the rest of the world, where weights are exogenous. As a consequence, the estimated reaction functions of countries...
