Response to Chemin and to Pitt
Response to Chemin and to Pitt
We reply to the discussion and criticisms of Matthieu Chemin (MC) and Mark Pitt (MP) to our paper ((Duvendack and Palmer-Jones (DPJ)) (all this issue). MC clarifies many issues which now make replication pure probable (but not yet achieved), and MP identifies a number of problems with DPJ (some of which are shared with Chemin, 2008). Chemin (2008) made at least one crucial undocumented and unrealistic assumption, and did not document many of his variable constructions. MP correctly identifies inappropriate members of control groups, and other problems, but his claim that his propensity score matching (PSM) results provide support for Pitt and Khandker's (1998 – PnK) most important claim is misleading as it is not robust. We see no reason to change our conclusion that PnK is limited as an evaluation of microfinance by a weak research design which cannot be convincingly mitigated by the sophisticated methods used in PnK, or by PSM.
