The Robust Result in Meta-analysis of Aid Effectiveness: A Response to Mekasha and Tarp
回应Mekasha和Tarp对Doucouliagos和Paldam研究的批评，指出其验证了援助对经济增长作用微弱的结论，并讨论方法论分歧。
Our study, Doucouliagos and Paldam (2008), has recently been critically discussed by Mekasha and Tarp (2011). In this paper we show that contrary to what they state, their study validates our basic analysis: Both papers confirm that the literature has shown that aid is of little economic importance in generating growth. M&T find some random coding errors with virtually no effect on the basic results. Furthermore, we discuss some methodological disagreements and show that their choice of the random effects model is not appropriate for the problem at hand, and that the way they use multiple MRAs contradicts the robust results reached at the basic analysis.
