In this paper, we perform a Tobit analysis of aid allocation, covering the period 1999-2002 and accounting for both altruistic and selfish donor motives. It turns out that poorer countries get clearly more aid from both bilateral and multilateral donors. Most donors are also found to direct...

In this paper, we perform a Tobit analysis of aid allocations, covering the period 1999-2002 and accounting for both altruistic and selfish donor motives. We first compare the allocative behavior of all bilateral donors taken together with that of multilateral aid agencies, and then look at nine...

The paper proposes two estimation approaches for duration models that are subject to right censored observations and selection effects. Main focus is on accelerated duration models and the estimators that are of the limited information type, i.e. they are not based on a fully specified selection...

Previous literature largely ignores the heterogeneity of aid channels used by each single donor country. We estimate Tobit models to assess the relative importance of recipient need, recipient merit and self-interest of donors for various channels of official and private German aid across a...

Interaction effects capture the impact of one explanatory variable x1 on the marginal effect of another explanatory variable x2. To explore interaction effects, so-called interaction terms x1x2 are typically included in estimation specifications. While in linear models the effect of a marginal...

To measure income inequality with right censored (topcoded) data, we propose multiple imputation for censored observations using draws from Generalized Beta of the Second Kind distributions to provide partially synthetic datasets analyzed using complete data methods. Estimation and inference...

Being closer to the poor, NGOs are widely believed to provide better targeted aid than state agencies. But empirical evidence is largely lacking. We contribute to closing this gap by drawing on an exceptionally detailed Swiss database that covers different forms of NGO aid and several official...
