The typical RD consists of controlling for a smooth function of the forcing variable (i.e. the score that has a cut-off where people on one side of the cut-off get the treatment, and those on the other side do not), and then looking for a discontinuity in the outcome of interest at this cut-off. A key practical problem is then how exactly to control for the forcing variable.<br /><br /></div></div></div>Mon, 08 Sep 2014 15:10:00 +0000David McKenzie1154 at http://blogs.worldbank.org/impactevaluationsRegression Discontinuity Porn

This has intrigued me with the possibility of a regression-discontinuity design to measure impacts of migrating. However, there are several problems – the points given tend to be lumpy (e.g.</p></div></div></div>Mon, 17 Dec 2012 14:24:11 +0000David McKenzie926 at http://blogs.worldbank.org/impactevaluationsWhy Students are Protesting all Over the World: Evidence From an RD in Chile: Guest post by Alex Solis

Despite the fact that our government counterparts are much more willing to consider a randomized promotion impact evaluation (IE) design these days, still this is often not possible. This could be, for example, because it has already been announced that the program is going to be implemented in certain areas starting on a certain date.</p></div></div></div>Fri, 19 Aug 2011 15:29:35 +0000Berk Ozler630 at http://blogs.worldbank.org/impactevaluations
