This paper analyses the impact of aid, and its optimal allocation, when conditionality is ineffective. It is assumed that the recipient government will implement its own preferences no matter what. In this set up, aid can still affect the behavior of a recipient, not through conditionality but...

The standard theory of optimal income taxation under uncertainty has been developed under the assumption that individuals maximize expected utility. However, prospect theory has now been established as an alternative model of individual behaviour, with empirical support. This paper explores the...

We consider the optimal income tax problem when income differences are due to differences in abilities and in preferences between consumption and leisure among individuals. We model this problem as an optimal control problem and develop a numerical method for solving it. The method is based on...
