We are currently running a randomised field experiment involving Local Support Organisations (LSOs) across Pakistan. We have completed the baseline, and the treatment (i.e. the implementation of protocols for reporting and for non-financial rewards) is ongoing. The LSOs have just completed sending the first self-reported data through that treatment, and at the time of registration of this document we have not accessed that data. This pre-analysis plan sets out the main regressions that we intend to run.

Experimental Details
We collected baseline data from 851 Local Support Organisations (‘LSOs’); of these, we are conducting a
randomised experiment with 836.1 This was collected through face-to-face interviews with representatives
of the LSO Executive Bodies (‘EBs’); we also collected data in all areas from an informed person in each
village (either in person or by telephone). In some cases, this was complemented by interviews with local

In addition to the baseline questionnaire, we anticipate obtaining two further sources of data from our
(i). At four six-monthly intervals over the next two years, treated LSOs will provide self-reports of
progress against key indicators (as Table 1 shows, these reports will either be against indicators for
governance or indicators for service provision); and
(ii). We will conduct two follow-up surveys of all LSOs, approximately one year and two years after the
start of the experiment.

Primary Outcomes
Primary Outcomes (end points)
We have a large number of outcomes, relating to LSO inputs, LSO activities, LSO outputs, and LSO reporting. All of these are defined clearly in the attached Pre-Analysis Plan document.

Experimental Design
Experimental Design
We are assigning Local Support Organisations to different reporting regimes, with a view to providing non-financial incentives to reward strong performers. We will test the effect of this incentive scheme on LSO performance. The details are set out in the submitted Pre-Analysis Plan document.

Randomization Method
Randomisation done in office by a computer.
Randomization Unit
We assigned treatment at the level of what we term a ‘sub-district’. For the purposes of our research, we define a ‘sub-district’ as
(i). A district (where ‘district’ has the meaning commonly used in Pakistan), or
(ii). If a district has more than 10 LSOs, the Tehsil.
