Corruption and Economic Growth: An Econometric Survey of the Evidence

        with Ralitza Dimova and Ahmad Saleh

        October 2012

        Does corruption grease or sand the wheels of economic growth? This paper uses
        meta-analysis techniques covering 460 estimates of the impact of corruption on growth
        from 41 studies to systematically evaluate this body of evidence. We find that publication
        bias, albeit acute, does not dissipate the genuine (and negative, on average) effect of
        corruption on economic growth. The main factors explaining the variation in these estimates
        are accounting for institutions and trade openness, (academic) affiliation of the author(s),
        and lack of fixed-effects (all produce less negative effects of corruption on growth).
